Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting machines, in particular to a heating mechanism for continuous casting machines. Background Art

[0002] The equipment required to complete this process is called a complete set of continuous casting equipment. The electromechanical and hydraulic integration of steel pouring equipment, continuous casting machine equipment, cutting area equipment, dummy bar collection and transportation equipment constitutes the core equipment of continuous steel casting, which is usually called a continuous casting machine. The continuous casting machine is mainly composed of a tundish, a crystallizer, a vibration mechanism, a dummy bar, a secondary cooling channel, a straightening machine and a cutting machine.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN201026521Y discloses a heating mechanism for a continuous casting machine. The utility model adopts the above technical structure. When in use, the heating device of the utility model is arranged in the furnace body of the continuous casting machine, and the heat-insulating material is arranged outside the graphite ring heating device. When the graphite ring heating device is powered on, the electrothermal effect of electricity makes the graphite ring heating device equivalent to a high-power resistance wire. After generating heat energy, it is radiated to the graphite pile, and then transmitted to the smelting raw materials in the field. It uses resistive heating to melt the smelting raw materials. Compared with the heating method of the existing continuous casting machine heating mechanism, it has the following obvious advantages: 1. Since the graphite furnace body will not break like the melting groove in the case of power outage, the mechanism will not be damaged by power outage. 2. Since no heating coil is used, there is no need to supply cooling water in the furnace body. 3. The life of the graphite furnace is basically equivalent to that of the induction furnace body, thereby extending the service life of the entire mechanism. 4. The furnace construction process is simple, and the material cost is greatly saved. When replacing graphite gantuan, there is no need to build the furnace every time, which can save a lot of manpower and material resources. 5. When smelting different raw materials and products such as copper-silver alloy and copper-magnesium alloy, the furnace can be reopened after removing the original smelting raw materials, so there is no need to rebuild the furnace, which can save a lot of time, manpower and money.

[0004] Although the existing heating mechanism for continuous casting machines saves time, manpower and money, the continuous casting machine tundish is mostly heated by induction heating coils during the heating process. The heating structure and the tundish are used in conjunction with each other. After the molten iron in the tundish is heated, the temperature of the molten iron will drop rapidly due to the single structure of the tundish, resulting in a large amount of energy waste, causing the induction heating coil to be used inefficiently and reducing the practicality of the heating mechanism.
