Description

Technical Field

[0001] This invention relates to the field of magnesium-carbon brick manufacturing technology, and in particular to a molding equipment and process for magnesium-carbon bricks with added anhydrous phenolic resin. Background Technology

[0002] In the production of magnesia-carbon bricks, the raw materials containing anhydrous phenolic resin need to be pressed and cured using molding equipment. Traditional molding equipment often uses a simple mold and press head structure, during which gas is generated inside the raw materials due to chemical reactions and physical compression.

[0003] When the punch presses the raw material in the mold, the mold becomes a closed space temporarily after the punch enters the mold due to the tight fit between the punch and the inner wall of the mold. During the process of the punch pressurizing the raw material, the inside of the mold becomes a closed high-pressure ring. The air inside the mold will also generate a lot of heat due to the high pressure. When the brick is formed and the punch is pulled out of the mold, the high-pressure air inside the brick expands rapidly under its own pressure. The phenolic resin, which is the binder, is also affected by the heat, which causes the brick to temporarily lose strength. The rapidly expanding high-pressure gas may cause the brick to crack. However, the existing equipment lacks an efficient exhaust design, which causes the gas to remain inside the brick and form defects such as pores and cracks. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes a molding equipment and process for adding anhydrous phenolic resin to magnesium carbon bricks.

[0005] This invention proposes a molding device for magnesium-carbon bricks with anhydrous phenolic resin, comprising a matching mold and a pressure plate. The pressure plate is mounted on the output shaft of a hydraulic rod, which is installed inside a control box. The control box is mounted on a frame. A base plate rests on a limiting part inside the mold. The base plate is mounted on the output shaft of a second hydraulic rod, which is fixed to the frame by a crossbeam. An exhaust structure is provided inside the mold. Magnesium-carbon brick raw material with anhydrous phenolic resin is placed into the mold. The control box controls the first hydraulic rod to drive the pressure plate downward. The raw material is extruded and molded by the pressure plate and the base plate. Gas generated during the molding process is discharged through the exhaust structure inside the mold. After the brick is molded, the second hydraulic rod is controlled to drive the base plate upward, lifting the brick to a height above the mold, and then the brick is removed.

[0006] Preferably, the exhaust structure includes an exhaust layer, and the inner wall of the mold has multiple exhaust ports for installing the exhaust layer. The outer walls on both sides of the mold are respectively provided with exhaust channels that communicate with the multiple exhaust layers on the same side. The gas generated during the extrusion molding of the magnesia-carbon brick raw material in the mold enters the exhaust channel through the exhaust layer and is finally discharged from the mold through the exhaust channel. This can also dissipate heat in time, which is conducive to the curing and molding of the brick.

[0007] Preferably, the exhaust structure is an elastic diaphragm, and a plurality of inner cavities for installing the elastic diaphragm are provided on the inner wall of the mold; when the raw material of magnesia-carbon brick is extruded in the mold, the air pressure in the mold cavity rises, pushing the elastic diaphragm to deform towards the inner cavity side, prompting the elastic diaphragm to form a spherical shape to collect the extruded gas, thus effectively avoiding the problem of instantaneous sharp rise in the internal air pressure of the mold when pressing the brick body.

[0008] Preferably, a molding device for magnesia-carbon brick added with anhydrous phenolic resin further includes:

[0009] A heat dissipation fan installed in the corresponding exhaust passage; a pressure acquisition module embedded on the inner wall of the mold for real-time monitoring of the air pressure fluctuation in the mold cavity and generating a pressure fluctuation coefficient through the control module; a temperature acquisition module installed on the outer wall of the first hydraulic rod for real-time monitoring of the temperature rise during the curing of phenolic resin and generating a temperature change coefficient through the control module; the control module in the control box comprehensively analyzes the generated pressure fluctuation coefficient and temperature change coefficient to generate an evaluation coefficient, compares the evaluation coefficient with a preset reference threshold, and controls the working state of the molding device according to the comparison result; the heat dissipation fan works in the exhaust passage to accelerate the gas discharge for cooling; the pressure acquisition module real-time monitors the air pressure fluctuation in the mold cavity of the mold and transmits it to the control module to generate a pressure fluctuation coefficient, and the temperature acquisition module real-time monitors the temperature rise during the curing of phenolic resin near the first hydraulic rod and transmits it to the control module to generate a temperature change coefficient; the control module comprehensively analyzes the two coefficients to generate an evaluation coefficient, compares it with the reference threshold, if the evaluation coefficient is within the threshold range, the device works normally, if it exceeds the threshold, the device is controlled to adjust the working parameters or stop.

[0010] Preferably, the output end and input end of the pressure acquisition module, and the output end and input end of the temperature acquisition module are respectively electrically connected to the input end and output end of the control module, and the output end of the control module is respectively electrically connected to the input end of the first hydraulic rod, the input end of the second hydraulic rod and the input end of the heat dissipation fan.

[0011] Preferably, the implementation steps for the control module to control the working state of the molding device according to the comparison result are as follows:

[0012] The pressure acquisition module acquires the air pressure fluctuation in the mold cavity; the temperature acquisition module acquires the temperature rise during the curing of phenolic resin; the control module calculates the pressure fluctuation coefficient, temperature change coefficient and evaluation coefficient; 0.8R threshold ≤ Rpg < R threshold: the rotation speed of the heat dissipation fan increases by 20%, and the current pressure holding time is maintained; R threshold ≤ Rpg < 2R threshold: the rotation speed of the heat dissipation fan increases by 50%, the pressure holding time is extended by 30%, and the audible and visual yellow light warning is triggered; Rpg ≥ 2R threshold: the device stops urgently, the device is locked, the audible and visual red light alarm is triggered, and the fault code is sent to the MES system.

[0013] Preferably, the logic for generating the pressure fluctuation coefficient is as follows:

[0014] Based on the actual air pressure data collected by the pressure acquisition module within a set time period, the deviation between the actual air pressure and the average air pressure is calculated, and a pressure fluctuation coefficient reflecting the intensity of gas compression and expansion is generated.

[0015] Preferably, the logic for generating the temperature change coefficient is as follows:

[0016] Based on the actual temperature data collected by the temperature acquisition module within a set time period, the deviation between the actual temperature and the average temperature is calculated, and a temperature change coefficient reflecting the resin softening trend is generated.

[0017] Preferably, the logic for generating the evaluation coefficients is as follows:

[0018] The control module performs dynamic trade-off calculations by coupling the pressure fluctuation coefficient and the temperature change coefficient, combined with preset weighting coefficients, to generate an evaluation coefficient that quantifies the competitive relationship between gas expansion force and brick crack resistance.

[0019] This invention also provides a molding process for magnesium-carbon bricks with anhydrous phenolic resin, including raw material pretreatment, mold loading, extrusion molding, dynamic monitoring and control, pressure holding and curing, and demolding and brick removal steps. During extrusion molding, an exhaust structure is used to exhaust air. During dynamic monitoring and control, parameters are acquired through a pressure acquisition module and a temperature acquisition module, and the operating status of the equipment is adjusted after analysis by the control module.

[0020] Compared with the prior art, the present invention provides a molding equipment and process for adding anhydrous phenolic resin to magnesia-carbon bricks, which has the following beneficial effects:

[0021] 1. A molding equipment and process for magnesium-carbon bricks with added anhydrous phenolic resin, which, through a specially designed venting structure (such as a venting layer or elastic diaphragm), can specifically vent the gas generated by the chemical reaction and extrusion of the raw materials during the pressing process, thereby significantly reducing defects such as pores and cracks inside the brick and improving the density and mechanical properties of the product.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Reference Figures 1-6 A molding device for magnesium carbon bricks with anhydrous phenolic resin, comprising a matching mold 1 and a pressure plate 6, the pressure plate 6 being mounted on the output shaft of hydraulic rod 1 5, the hydraulic rod 1 5 being mounted inside a control box 4, the control box 4 being mounted on a frame 3, a base plate 2 being provided inside the mold 1 and resting on a limiting part 14, the base plate 2 being mounted on the output shaft of hydraulic rod 2 8, and the hydraulic rod 2 8 being fixed to the frame 3 by a crossbeam 7, and an exhaust structure being provided inside the mold 1;

[0033] In use, magnesium carbon brick raw materials with added anhydrous phenolic resin are placed into mold 1. Control box 4 controls hydraulic rod 5 to drive pressure plate 6 downward. The raw material is extruded and molded by pressure plate 6 and bottom plate 2. The gas generated during the molding process is discharged through the exhaust structure in mold 1. After the brick is pressed and molded, control hydraulic rod 8 to drive bottom plate 2 upward, lift the brick to a height above mold 1, and then remove the brick.

[0034] In embodiment 1, the exhaust structure includes an exhaust layer 10, and the inner wall of the mold 1 is provided with a plurality of exhaust ports 9 for installing the exhaust layer 10. The outer walls on both sides of the mold 1 are respectively provided with exhaust channels 11 that communicate with the plurality of exhaust layers 10 on the same side.

[0035] It should be noted that the exhaust layer 10 only needs to possess air permeability, material barrier properties, and pressure resistance; therefore, its material and structure are not limited. In this application, the exhaust layer 10 specifically includes a support mesh layer (sintered stainless steel mesh), a filter buffer layer (mullite fiber felt), and a functional surface layer (silicon carbide microporous coating). Air permeability: under 15MPa molding conditions, the air permeability is ≥200L / (m³). 2 •s)(@25℃); Raw material barrier rate: Retention efficiency of magnesia-carbon brick raw materials (particle size ≤0.075mm) >99.97%; Thermal stability: After 300 thermal cycles (room temperature → 600℃ → water quenching), the pore size change rate is <3%;

[0036] During use, the gas generated during the extrusion molding process of the magnesia-carbon brick raw material in the mold 1 enters the exhaust channel 11 through the exhaust layer 10 and is finally discharged from the mold 1 through the exhaust channel 11. This can also dissipate heat in time, which is conducive to the curing and molding of the brick.

[0037] In embodiment 2, the exhaust structure is an elastic diaphragm 13, and the inner wall of the mold 1 has a plurality of inner cavities 12 for installing the elastic diaphragm 13.

[0038] When the magnesia-carbon brick raw material is squeezed in the mold 1, the air pressure inside the mold cavity increases, which pushes the elastic diaphragm 13 to deform towards the inner cavity 12, causing the elastic diaphragm 13 to form a spherical shape to collect the squeezed gas, thereby effectively avoiding the problem of sudden increase in air pressure inside the mold when pressing the brick.

[0039] In another embodiment, a molding apparatus for magnesium-carbon bricks with anhydrous phenolic resin further includes:

[0040] Cooling fan 15 is installed in the corresponding exhaust channel 11;

[0041] The pressure acquisition module 16 is embedded in the inner wall of the mold 1 and is used to monitor the air pressure fluctuation in the mold cavity in real time and generate the pressure fluctuation coefficient through the control module.

[0042] Temperature acquisition module 17 is installed on the outer wall of hydraulic rod 5 to monitor the temperature rise process of phenolic resin curing in real time and generate temperature change coefficient through control module.

[0043] The control module inside control box 4 performs a comprehensive analysis of the generated pressure fluctuation coefficient and temperature change coefficient to generate an evaluation coefficient. The evaluation coefficient is then compared with a pre-set reference threshold, and the working status of the molding equipment is controlled based on the comparison results.

[0044] It should be noted that the pressure acquisition module 16 can be a piezoresistive pressure sensor or other device that can monitor the air pressure fluctuations in the mold cavity in real time, the temperature acquisition module 17 can be a K-type thermocouple or other device that can monitor the temperature rise process of phenolic resin curing in real time, and the control module is an embedded controller (such as the STM32 series) that integrates data fusion algorithms. Therefore, the pressure acquisition module 16, the temperature acquisition module 17 and the control module are not specifically limited here and can be selected according to actual needs.

[0045] During use, the cooling fan 15 operates within the exhaust channel 11 to accelerate gas discharge for cooling; the pressure acquisition module 16 monitors the air pressure fluctuations within the mold cavity of the mold 1 in real time and transmits the data to the control module to generate a pressure fluctuation coefficient; the temperature acquisition module 17 monitors the curing temperature rise of the phenolic resin near the hydraulic rod 5 in real time and transmits the data to the control module to generate a temperature change coefficient; the control module comprehensively analyzes the two coefficients to generate an evaluation coefficient, compares it with a reference threshold, and if the evaluation coefficient is within the threshold range, the equipment operates normally; if it exceeds the threshold, the control module adjusts the operating parameters or stops the machine.

[0046] The output and input terminals of the pressure acquisition module 16 and the output and input terminals of the temperature acquisition module 17 are electrically connected to the input and output terminals of the control module, respectively. The output terminal of the control module is electrically connected to the input terminal of the hydraulic rod 1 5, the input terminal of the hydraulic rod 2 8, and the input terminal of the cooling fan 15, respectively.

[0047] In another embodiment, the control module within control box 4 comprehensively analyzes the generated pressure fluctuation coefficient and temperature change coefficient to generate an evaluation coefficient. The evaluation coefficient is then compared with a pre-set reference threshold, and the following steps are taken to control the working state of the molding equipment based on the comparison results:

[0048] Real-time monitoring: Pressure acquisition module 16 collects air pressure fluctuations inside the mold cavity; temperature acquisition module 17 collects the temperature rise process of phenolic resin curing.

[0049] Coefficient calculation:

[0050] Pressure fluctuation coefficient Pσ: quantifies the intensity of sudden changes in gas pressure within the mold cavity. Its core function is to reflect the severity of gas compression-expansion during pressurization / depressurization of the punch, and characterizes the impact risk of high-pressure gas on the brick structure.

[0051] The generation logic for the pressure fluctuation coefficient is as follows:

[0052] S1. The actual air pressure inside the mold cavity at different times within time T during the pressing of the brick is obtained through the pressure acquisition module 16. The actual air pressure obtained at the i-th time within time T is calibrated as... i is a positive integer;

[0053] S2. Calculate the pressure fluctuation coefficient. The expression for the calculation is:

[0054]

[0055] In the formula, q represents the average air pressure over time T; q represents the number of samples taken over time T.

[0056] Temperature change coefficient TΔ: Characterizes the local temperature rise rate during the curing process of phenolic resin. Its core function is to monitor the critical point of strength decay caused by resin softening due to heat and to identify the heat accumulation area in the mold 11 (which is prone to gas expansion).

[0057] The generation logic for the temperature change coefficient is as follows:

[0058] S1. The actual curing temperature of the phenolic resin at different times within time T during the pressing of the brick is obtained through the temperature acquisition module 17, and the actual temperature obtained at time j within time T is calibrated as... j is a positive integer;

[0059] S2. Calculate the temperature change coefficient. The expression for the calculation is:

[0060]

[0061] In the formula, Let r be the average temperature over time T; and r be the number of samples taken over time T.

[0062] The evaluation coefficient Rpg: This coefficient represents the cracking risk level resulting from both sudden changes in air pressure and softening due to temperature rise. Its core function is to quantify the competitive relationship between gas expansion force and the crack resistance strength of the brick. It is analyzed using a formulaic approach through a control module, based on the following formula:

[0063]

[0064] In the formula, w1 and w2 are weighting coefficients (e.g., w1 = 1.8, w2 = 1.5, the specific values ​​are dynamically determined based on experimental data), and w1 and w2 > 1.

[0065] Dynamic adjustment: 0.8R threshold ≤ Rpg < R threshold: The rotation speed of the cooling fan 15 increases by 20%, and the current holding time is maintained. The purpose is preventive intervention: When the coefficient approaches the threshold, enhance the air cooling in advance to inhibit the softening trend of phenolic resin; R threshold ≤ Rpg < 2R threshold: The rotation speed of the cooling fan 15 increases by 50%, and the holding time is extended by 30%. Trigger the yellow warning light of the sound and light warning. The purpose is active inhibition: By strengthening heat dissipation + extending the holding time, balance the air pressure release and the resin curing rate; Rpg ≥ 2R threshold: The equipment stops suddenly, locks the equipment, triggers the red warning light of the buzzer alarm, and sends the fault code to the MES system. The purpose is safety protection: To avoid the structural damage of the brick body, manual intervention is required for troubleshooting.

[0066] The present invention also provides a molding process for magnesia-carbon bricks added with anhydrous phenolic resin, including steps of raw material pretreatment, mold loading, extrusion molding, dynamic monitoring and regulation, pressure holding and curing, and demolding and brick taking. During extrusion molding, exhaust is carried out in cooperation with an exhaust structure. During dynamic monitoring and regulation, parameters are obtained through a pressure acquisition module and a temperature acquisition module, and the working state of the equipment is adjusted after analysis by a control module.

[0067] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
