Mineral wool, rock wool furnace - AC slag furnace

Application of equipment:

This equipment is used to receive hot melt slag from ironmaking blast furnace, through a small amount of tempering (adjusting the mass of 10-15%), adjust the current and voltage to make the temperature of the flow port is stable, and use the patented equipment copper gate to control the flow of slag port, and continuously transport to the centrifuge to prepare mineral wool. By adjusting a small amount of mass (adjusting 10% of mass), the current and voltage are adjusted to make the temperature of the flow port stable, and the flow rate of the slag port is controlled by the patented equipment copper gate, which is continuously transmitted to the electric furnace equipment for preparing mineral wool.

Process overview:

The slag bag containing industrial waste slag is transported to the electric furnace workshop with a slag truck or rail car, poured into the furnace, began to raise the temperature and adjust the composition, and determined by temperature measurement and sampling to meet the production requirements of mineral wool, and transported to the centrifuge and subsequent mineral wool production line to provide raw materials for the mineral wool production line.
