Safe pouring production system for refractory materials

Abstract

The invention discloses a safety casting production system for a refractory material. The safety casting production system comprises an electric arc furnace, a heat exchanger, a water storage tank, a cooling tower, a head water tank, a water supplementing tank arranged in a sealed manner, a water supplementing pump and a refractory material rotating casting device. The refractory material rotating casting device comprises a casting base, a casting supporting plate and a casting rotating bearing plate. A water jacket is arranged on the electric arc furnace and is connected with the water supplementing tank. The water supplementing tank is connected with the head water tank, and the head water tank is connected with the water supplementing pump. According to the safety casting production system, the phenomenon that the electric arc furnace releases high-temperature thermal pollution to the outside can be avoided, the phenomenon that steam is dispersed into a plant in the production process is avoided, the phenomenon that cooling water releases steam pollution outwards is avoided, in addition, water resources can be recycled, the electric arc furnace is effectively cooled, rotating casting is achieved in the production process, the time needed for replacing casting boxes is greatly shortened, and the production efficiency is improved. According to the safety casting production system, the work safety of the electric arc furnace can also be ensured during the accidental power failure.

Description

Technical field [0001] The invention relates to the technical field of refractory material production, in particular to a refractory material pouring system. Background technique [0002] In the production process of molten refractory materials, electric arc furnaces are commonly used equipment. During operation, the electric arc furnace melts the refractory raw materials in it, so it needs to continue to maintain a high temperature state during the production process. Too high temperature will reduce the service life of the equipment and make the staff unable to work normally in the workshop. Therefore, it is necessary to cool the furnace wall of the electric arc furnace. While maintaining the high temperature in the furnace, the high temperature area is controlled in the electric arc furnace to prevent a large amount of heat in the furnace from being transferred to the environment, reducing the service life of the equipment and making the workshop unsuitable for labor. operat...

Problems solved by technology

The disadvantages of this cooling structure are: the temperature of the cooling water is high after being heated by the electric arc furnace, and even boiling occurs when the flow rate is small; when the cooling water is discharged, the steam diffuses, which pollutes the factory area and damages the walls of the factory area due to long-term humidity

At present, domestic manufacturers of molten casting refractories basically adopt the method of driving or forklift lifting to cast. The biggest disadvantage of this pouring method is that the driving and forklift have to have a running process after each pouring. It belongs to intermittent production. According to different brick shapes There may even be more than six cases of pouring in each furnace, making the pouring time about 30 minutes, which results in a very low pouring efficiency. During this period, the electric furnace has to keep heating the material liquid in the electric arc furnace, resulting in increased power consumption
