Description

Technical Field

[0001] This invention relates to the field of metallurgical mixing furnace technology, specifically a metallurgical mixing furnace with water-cooled casting function. Background Technology

[0002] Metallurgy refers to the process and technology of extracting metals or metal compounds from minerals and processing them into metal materials with certain properties using various processing methods. The metallurgical industry is an important basic industry of the national economy. As a key piece of equipment in the metallurgical process, the mixing furnace is widely used for heat preservation, composition adjustment and preparation before casting of molten metal. Traditional metallurgical mixing furnaces are used to cast molten metal into ingots. Traditional casting relies on natural cooling or simple air or water cooling, which results in slow cooling rates and low production efficiency. In addition, many steps from the discharge of the mixing furnace to the forming and removal of the casting depend on manual operation, which not only results in high labor intensity and limited production efficiency, but also poses safety risks due to personnel operating close to the furnace. Therefore, we propose a metallurgical mixing furnace with water-cooled casting function. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a metallurgical mixing furnace with water-cooled casting function. The molten metal inside the crystallizer is cooled and cast by cooling thread grooves and continuously circulating coolant. The coolant sprayed from the annular nozzle is atomized and sprayed onto the surface of the casting for secondary cooling. At the same time, the entire device adopts automated metallurgical casting to reduce the safety problems that are easily caused by manual operation, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a metallurgical mixing furnace with water-cooled casting function, comprising a box body and a cooling casting unit; Box body: The top surface is provided with an outer shell, and the furnace body is fixed inside the outer shell. The bottom end of the furnace body is conical. The bottom outlet of the furnace body is connected to the top of the control valve. The right side of the box body is fixed inside. The top surface of the furnace body is connected and fixed with a liquid replenishment pipe. The furnace body is equipped with a mixing unit inside. Cooling casting unit: includes a crystallizer, cooling threaded groove, liquid tank and negative pressure pump. The metal liquid port on the top surface of the crystallizer is connected to the bottom end of the control valve. The cooling threaded groove is opened on the outer side of the inside of the crystallizer. The liquid inlet of the cooling threaded groove is connected to the liquid outlet pipe of the negative pressure pump. The liquid tank is placed inside the tank frame. The liquid outlet of the cooling threaded groove is connected to the liquid inlet pipe of the liquid tank. The negative pressure pump is placed inside the liquid tank. It also includes a control box, which is fixed to the front side of the housing. The input terminals of the control valve and the negative pressure pump are electrically connected to the output terminal of the control box, and the input terminal of the control box is electrically connected to the output terminal of an external power source.

[0005] The molten metal is mixed and stored inside the furnace. A control valve is set up to transport the molten metal into the crystallizer. At the same time, a negative pressure pump is started to circulate coolant into the cooling thread groove to cool and cast the molten metal inside the crystallizer.

[0006] Furthermore, the cooling casting unit also includes a housing, an intelligent three-way valve, a delivery pipe, an atomizing nozzle, connecting rods, and an annular spray pipe. The housing is connected to the left side of the interior of the housing. The through hole on the right side of the housing corresponds to the discharge port on the left side of the crystallizer. Connecting rods are provided at both ends of the outer side of the annular spray pipe, and the two connecting rods are fixed to the inner walls on both sides of the housing.

The input end of the intelligent three-way valve is electrically connected to the output end of the control box. When the intelligent three-way valve is activated, the coolant is delivered into the annular spray pipe. Thus, when the casting is completed and removed, the atomizing nozzles on the inner side of the annular spray pipe atomize the coolant and spray it evenly on the surface of the casting to further enhance the cooling effect and improve the efficiency of subsequent casting cooling.

The right end of the bracket is connected to the middle of the left side of the sealing cap. The sealing cap is inserted into the through hole on the right side of the housing and corresponds to the discharge port on the left side of the crystallizer. The input ends of the linear motor and the electric telescopic rod are electrically connected to the output end of the control box. Activating the electric telescopic rod in conjunction with the linear motor can automatically open and seal the discharge port of the crystallizer.

[0010] Furthermore, the cooling casting unit also includes a semiconductor cooler and a temperature sensor. The semiconductor cooler is fixed inside the liquid tank, with its heat-dissipating end located outside the liquid tank. The temperature sensor is installed on the right side of the liquid tank, with its detection probe located inside the liquid tank. The input end of the semiconductor cooler is electrically connected to the output end of the control box, and the output end of the temperature sensor is electrically connected to the input end of the control box.

[0023] The working principle of a metallurgical mixing furnace with water-cooled casting function provided by this invention is as follows: First, molten metal is added into the furnace body 5 through the replenishment pipe 8. The electromagnetic heater 36 is activated to control the electromagnetic tube 35 to continuously heat the molten metal inside the furnace body 5. The motor 31 drives the mixing blades 34 on the outside of the fixed shaft 33 to continuously stir the molten metal. The mixing blades 34, which are attached to the inner wall of the furnace body 5, work with the bottom conical design of the furnace body 5 to reduce molten metal waste. When casting is required, the electric telescopic rod 215 is activated to seal the outlet of the crystallizer 21 with the cover 214. The control valve 6 is used to transport the molten metal into the crystallizer 21. Simultaneously, the negative pressure pump 24 is activated to circulate coolant into the cooling threaded groove 22 to cool and cast the molten metal inside the crystallizer 21. After the casting inside the crystallizer 21 is completed, the linear motor 211, in conjunction with the electric telescopic rod 215, opens the cover 214 and moves it out of the housing 25. This automated production process... To improve efficiency and avoid safety issues that may arise from close-range operation, the intelligent three-way valve 26 is activated to deliver coolant into the annular nozzle 210. Subsequently, an external robotic arm pulls out the casting. When the casting is removed after casting, the atomizing nozzle 28 on the inner side of the annular nozzle 210 atomizes the coolant and sprays it evenly onto the surface of the casting to further enhance the cooling effect and improve the efficiency of subsequent casting cooling. The conical drip groove 221 collects the dripping coolant and pumps it back into the liquid tank 23 for later use. The temperature sensor 223 detects the temperature of the coolant inside the liquid tank 23 and activates the semiconductor cooler 222 to lower the coolant to a suitable temperature to ensure the effective casting cooling. The temperature measuring camera 10 inside the placement rack 9 measures the temperature of the cooled casting and adjusts the coolant circulation speed according to the temperature change to ensure the best cooling effect. This completes the water-cooled casting process of the molten metal.
