Problems solved by technology

[0002] At present, most of the existing rock wool production processes are cumbersome and complicated. Most of the equipment for melting ore in rock wool production uses cupolas, which melt the ore through the heat generated after coke combustion, and a large amount of waste gas is generated during the melting process. The exhaust gas contains harmful gases such as carbon monoxide and sulfur dioxide, which must be desulfurized and denitrified after incineration. The rock wool industry has strict exhaust gas emission standards, which will undoubtedly reduce the living space for rock wool produced by cupola furnaces.

Abstract

The invention discloses a production technology of rock wool. The technology comprises the following steps: (1) preparing raw materials: mixing dolomite, basalt, blast-furnace slag and waste residuesas raw materials; (2) melting the raw materials: adding the raw materials into an electric furnace and melting into molten rock; (3) centrifuging to form fibers: spinning the molten rock into the fibers through a centrifugal machine and collecting the fibers; (4) molding a cotton felt: paving the collected fibers on a pendulum bob cotton paving machine and molding the fibers into the cotton felt through a molding conveyor; (5) molding a cotton plate: pleating the cotton felt and pressurizing and molding; drying and curing to obtain the cotton plate; (6) cutting: cutting the cotton plate into aregulated size. According to the production technology of the rock wool, the electric furnace is used as raw material melting equipment and the production of harmful gas is effectively prevented; a waste gas treatment link is avoided and a production process is simple and easy to realize.
