Mineral wool, rock wool furnace - silica manganese slag mineral
wool furnace
Application of equipment:
The equipment is used to receive the hot melt slag from the silicon
manganese ore furnace, through a small amount of tempering (mass
adjustment 10%), 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 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.
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;
Main parameters and indicators:
1 Furnace capacity ~ 50t
2 Shell diameter Φ5200 ~ Φ5600
3 Shell height ~ 3500 mm
4 Electrode diameter Φ400mm
5 Electrode pole circle Φ1350 ~ Φ1400mm
6 Maximum electrode stroke 1800 mm
7. Transformer rated capacity 4000 KVA
Performance index:
(1) Slag production capacity: ~ 5 tons/hour (annual output of more
than 30,000 tons)
(2) Slag temperature (mineral wool machine requirements) ~ 1500℃
(3) Original slag temperature ~ 1300℃ (to be measured)
(4) tons of cotton power consumption 350-500KWh/T;
3. Ton of cotton electrode consumption: 2.5-3.0Kg/t
