Low cement castable has the characteristics of high density, low porosity, high strength, low wear, thermal shock resistance and corrosion resistance. It is mainly suitable for metallurgy, electric power, petroleum, chemical industry and various silicate kilns, such as refining outside the furnace Some components of the device, the outer refining bag cover, the electric furnace top lining body, the heating furnace soaking furnace lining, the annealing furnace lining, the tundish lining, the tapping groove, the high temperature burner and the blast furnace tapping groove cover, the hot metal ladle Lining, etc.

1. Precautions before opening the furnace

The intermediate frequency electric furnace must be checked for electrical equipment, water cooling system, inductor copper pipes, etc. before the furnace is opened. The furnace can only be opened when these equipments are in good condition to ensure the safety of heat treatment. Personnel who are specially responsible for power transmission and furnace opening, and the responsible personnel shall not leave their posts without authorization, and the external conditions of the inductor and the crucible must be supervised during work to prevent someone from touching the inductor and cable after the power supply, affecting the operation of the intermediate frequency electric furnace. normal operation or a safety accident occurs.

2. Precautions after opening the furnace

After the intermediate frequency electric furnace is started, when charging, the charge should be checked to avoid mixing inflammable and explosive and other harmful substances. After the molten liquid is filled to the upper part, it is not allowed to add larger blocks; in order to avoid explosion accidents, it is necessary to ensure that the pouring site and the pit in front of the furnace are free of water and obstacles; and two people are required to cooperate when pouring. The remaining molten steel can only be poured at the designated location, and cannot be poured everywhere.
