Mineral wool, rock wool electric furnace - AC rock wool furnace
Application of equipment:
This equipment is used to melt the production of rock wool basalt,
slag, dolomite and auxiliary materials, after heating homogeneous
insulation, control the temperature and flow of the slurry
transported to the centrifuge, continuous production of rock wool
products.
Process overview:
Basalt ore and auxiliary materials are the main raw materials of
rock wool electric furnace. After drying by drying system, the
prepared raw materials are loaded into the high bin of electric
furnace through feeding system for storage. After measuring and
weighing the raw materials through the distributing system, the raw
materials are lowered into the furnace by the feeding pipe in the
furnace, and the thin materials are continuously heated by electric
power for submerged arc smelting. After melting to meet the
temperature requirements, the thin materials are released through
the slag outlet and enter the centrifuge to make rock wool
products.
Structural features:
(1) The operation flexibility of the equipment is strong, the slag
flow is controllable, the operation is simple;
(2) Adopt advanced impedance control method and introduce
temperature feedback;
(3) high degree of automation, centralized control of the whole
smelting process;
(4) Fast melting speed, continuous feeding, continuous discharge;
(5) smelting melting process without coke;
(6) The equipment performance is stable and can work continuously
for 24 hours;
(7) Production waste can be recycled, resulting in less waste;
(8) The flue gas is easy to recover, and the emission is small
(mainly for soot 350mg/m²);
