Mineral Wool, Rock Wool Electric Furnace - AC Rock Wool Furnace(New)

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);
