DETAILED DESCRIPTION

[0018] The alloy heating furnace is generally installed above the converter post-rotary chute, and the required alloy to be roasted is weighed by a forklift or a high-position silo and then added to the heating furnace, the equipment is automatically started to roast for 10-15 minutes, and after the roasting is completed, the heating furnace is opened to put the alloy directly into a ladle.

[0019] However, the current alloy heating furnace control assembly is single, the control function is limited, and it cannot meet the diversified production conditions and cannot be flexibly adjusted according to the diversification of the production conditions. It also cannot respond to emergencies in time, and the safety and stability still need to be further improved.

[0020] Therefore, the present application provides a converter post-alloy heating furnace which has multiple control assemblies and can solve the above problems to a certain extent.

[0021] Specifically, the present application provides a converter post-alloy heating furnace, as shown in the accompanying drawings, comprising: Figure 1

[0022] a furnace body 1 for heating alloy materials;

[0023] a combustion system comprising an ignition groove connected with the furnace body 1 for igniting fuel in the furnace body 1 and a burner 22 connected with the furnace body 1 for controlling the combustion degree of the furnace body 1;

[0024] a fuel delivery pipeline connected with the furnace body 1 for delivering fuel, wherein the fuel delivery pipeline is provided with multiple control instruments and detection instruments.

[0025] The furnace body 1 has high temperature resistance and corrosion resistance, is usually made of high temperature resistant and corrosion resistant materials, can withstand the heating process of high temperature alloy materials, and can resist the corrosion of corrosive gases or substances in the furnace; and has strong adaptability, the internal space of the furnace body 1 can be adjusted according to the types and quantities of alloy materials to adapt to different heating requirements.

[0026] The ignition groove can quickly ignite the fuel in the furnace body 1, shorten the starting time of the heating furnace, prevent backfire, prevent gas leakage, etc., and ensure the safety during operation.

[0027] The burner 22 can accurately control the combustion degree in the furnace body 1, including the size, shape and temperature of the flame, to meet the heating requirements of different alloy materials.

[0028] The control instruments and detection instruments can monitor the flow, pressure, temperature, etc. in the fuel delivery pipeline in real time, ensure the stable delivery of fuel and the normal combustion in the furnace, and through real-time monitoring and automatic adjustment, the safety of the fuel delivery process can be ensured, and safety accidents caused by fuel leakage, overpressure, etc. can be prevented.

[0029] ​Further, the ignition groove comprises a top ignition groove 211 and a bottom ignition groove 212, the top ignition groove 211 is located above the furnace body 1 and connected with the furnace body 1 through a top ignition port, and the bottom ignition groove 212 is located below the furnace body 1 and connected with the furnace body 1 through a bottom ignition port.

[0030] The arrangement of the top ignition groove 211 and the bottom ignition groove 212 enables the fuel inside the furnace body 1 to be ignited at multiple positions simultaneously. This multi-point ignition method helps the fuel to reach a stable combustion state more quickly, thereby improving the combustion efficiency; through the simultaneous ignition of the top and bottom ignition grooves 212, a more uniform flame distribution can be formed, which helps the alloy material inside the furnace body 1 to be heated more uniformly, avoiding the occurrence of local overheating or insufficient temperature, thereby improving the quality of the alloy material; when a certain ignition groove fails, normal heating can still be ensured through another ignition groove.

[0031] Further, the burner 22 is located between the top ignition groove 211 and the bottom ignition groove 212.

[0032] The burner 22 is located between the top ignition groove 211 and the bottom ignition groove 212, which can form a more balanced flame distribution. The top and bottom ignition grooves 212 are responsible for initially igniting the fuel, while the burner 22 is responsible for maintaining and enhancing the combustion intensity of the flame. This layout helps the fuel to burn more fully in the furnace, improving the combustion efficiency. At the same time, by arranging the burner 22 between the top ignition groove 211 and the bottom ignition groove 212, it can also be flexibly adjusted according to production needs. For example, when rapid heating is needed, the power of the burner 22 can be increased; when temperature stability needs to be maintained, the power of the burner 22 can be reduced. This flexibility enables the heating furnace to better adapt to different production conditions.

[0033] Further, the fuel delivery pipeline comprises a first pipeline 31 and a second pipeline 32, the first pipeline 31 is used to input external fuel and deliver it to the furnace body 1, and the control instrument and detection instrument are arranged in the first pipeline 31; one end of the second pipeline 32 is connected with a fan 32a, and the other end is connected with the first pipeline 31, and the connection between the first pipeline 31 and the second pipeline 32 is a pipeline connection port.

[0034] The first pipe 31, serving as the main input channel for external fuel, is designed to ensure a stable fuel supply. By precisely controlling the fuel input quantity and rate, the combustion process within the furnace 1 can be ensured to be continuous and stable, thereby meeting production needs. This is crucial for adjusting combustion conditions, optimizing combustion efficiency, and preventing safety accidents. Through precise fuel input control, the first pipe 31 helps achieve complete fuel combustion. This not only improves combustion efficiency and reduces energy consumption but also lowers emissions, meeting environmental protection requirements.

[0035] The second pipe 32 is connected to a blower 32a at one end and to the first pipe 31 at the other. The blower 32a introduces air or other combustion-supporting gases into the first pipe 31, allowing for thorough mixing with the fuel. This mixing promotes more complete combustion and improves combustion efficiency. The introduction of air optimizes the combustion process, providing the necessary oxygen and promoting complete combustion. Simultaneously, the airflow helps to distribute heat more evenly within the furnace body 1, improving heating efficiency. Furthermore, the second pipe 32 enhances the furnace's safety. By adjusting the speed of the blower 32a and the amount of air input, the oxygen concentration and combustion speed within the furnace body 1 can be precisely controlled, preventing accidents caused by excessively fast or slow combustion. Additionally, the connection between the second pipe 32 and the first pipe 31 is a pipe connection port, facilitating maintenance and repair. When a pipe malfunctions or requires cleaning, the connection port can be disconnected for individual operation without affecting the overall operation of the furnace.

[0036] Furthermore, the control instruments include: a manual regulating valve 311b, an electric regulating valve 311c, and a gate valve 311a; the detection instruments include: a pressure gauge 312a, a temperature gauge 312b, and a flow meter 312c.

[0037] The manual regulating valve 311b allows the operator to directly and manually adjust the fuel flow rate. By rotating the valve handle, the diameter of the fuel pipeline can be changed, thereby controlling the amount of fuel input. The electric regulating valve 311c automatically adjusts the fuel flow rate by receiving signals from the detection instrument. The gate valve 311a is mainly used to cut off or connect the fuel pipeline. When it is necessary to stop the fuel supply, the gate valve 311a can be closed to cut off the fuel flow. When it is necessary to restore the supply, the gate valve 311a can be opened to allow fuel to pass through.

[0038] The pressure detector 312a is used to monitor the pressure changes in the fuel pipeline in real time, and can convert the pressure signal into an electrical signal or a mechanical signal for monitoring and analysis by the operator or the control system. The temperature detector 312b is used to measure the temperature inside the heating furnace or in the fuel pipeline, which can convert the temperature signal into an electrical signal or a digital signal for real-time monitoring and recording. The flow detector 312c is used to measure the flow in the fuel pipeline. It can calculate the flow value by measuring the speed, pressure difference or mass of the fluid, etc.

[0039] The control instruments and detection instruments play a crucial role in the converter post-alloy heating furnace. They not only ensure the stable operation and high efficiency of the heating furnace, but also improve the safety and reliability. By reasonably configuring and using these instruments, the combustion process can be further optimized, energy consumption and emissions can be reduced, production efficiency and product quality can be improved.

[0040] Further, the control instruments are located closer to the first pipeline 31 side of the pipeline connection port. Since the first pipeline 31 is used to input external fuel, the control instruments are located closer to the first pipeline 31 side of the pipeline connection port to monitor the flow, pressure and other key parameters of the fuel in real time and adjust the fuel supply according to these parameters. By placing the control instruments near the first pipeline 31, the instruments can directly and accurately monitor the fuel state input from the first pipeline 31. In this way, the operator or the automatic control system can quickly respond and adjust the fuel supply to meet the combustion needs of the heating furnace.

[0041] Further, the detection instruments are located closer to the furnace body 1 side of the pipeline connection port. The main function of the detection instruments is to monitor the temperature, pressure, flow and other key parameters inside the furnace body 1 in real time. By placing these instruments near the furnace body 1, the instruments can directly and accurately monitor the actual state inside the furnace body 1. In this way, the operator can real-time understand the combustion situation of the furnace body 1, so as to make accurate judgments and decisions. During the fuel delivery process, the pipeline connection port may introduce certain disturbances or pressure losses. If the detection instruments are placed on the other side of the connection port, these disturbances may interfere with the readings of the instruments, causing measurement errors. By placing the instruments near the furnace body 1, the interference can be minimized, improving the accuracy and reliability of the measurements.

[0042] According to a preferred embodiment, the furnace body 1 is also provided with an alarm device 4 for judging the carbon monoxide content in the production environment, and issuing an alarm when the carbon monoxide content exceeds a set threshold.

[0043] Timely discovery and treatment of carbon monoxide leakage and other problems can avoid damage to workers due to long-term exposure to high-concentration carbon monoxide environment, improve safety, ensure smooth production, and reduce maintenance costs.
