Hot melt Slag Granulation Electric Holding 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.
Process description:
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.
Structural features:
1. Less smoke emissions and obvious environmental benefits;
2. High efficiency: the melting efficiency of electric furnace is twice that of coke cupola;
3. Electric furnace flow control is stable; Ensure the stability of the stock flow from the following aspects:
① The volume design and electrode design of electric furnace are reasonable;
② Precision design of water cooling outlet control;
③ Mobile chute with free movement.
4. Low energy consumption: the main power consumption of hot slag in electric furnace: 350-400 degrees/ton of cotton, graphite electrode consumption is 2-3kg/ ton of cotton.
5. High degree of electrical automation;
