A necessary refractory material for the eccentricity furnace tapping, that is, drainage sand, is mainly used as the main raw material in Henan forsterite and the magnesia of Liaoning Dashiqiao, and the carbon material of Hubei Yichang as an additive. The drainage sand has good dispersive fluidity, high refractoriness, no sintering, non blockage, 100% of the drainage rate of tapping rate. The use temperature is more than 1750 degrees C, no chemical reaction with the composition of steel and alloy, the quality of storage does not occur, it can meet the requirements of steelmaking process, and it is the ideal refractory for steelmaking in eccentric furnace.
Stuffing sand is made of chromium ore, forsterite, quartz sand, flux and additive, which is composed of specific particles. It is suitable for all kinds of ladle and refining ladle drainage sand. It has the characteristics of simple operation, safety and high opening rate.
Can be adjusted according to the needs of the user
