Rock wool, also known as rock wool, mineral wool is one. To natural rocks and minerals and other raw materials made of fluffy short, thin fibers. 70 years of the 20th century is widely used in metallurgy, machinery, building materials, petroleum, chemical industry. The natural rock, ore and other raw materials, or other pools in the cupola melting kiln (temperature 2000 ℃ below), with 50 atmospheres of pressure strong winds, sudden cold as fibrous. Or rejection wire method, the melt flow in the multi-turn off the rotor, through the centrifugal force thrown into the fiber, usually 3 to 9 microns in diameter, bulk density of 50 ~ 200 kg / m ^ 3, room temperature, thermal conductivity of 0.029 ~ 0.046 W / m open, following in 600 ℃ 0.111 ~ 0.145 W / m open, non-combustible, not mold, not boring. By using the temperature sub-ordinary rock wool (less than 900 ℃) Rock wool is a natural rock such as basalt, gabbro, dolomite, iron ore, bauxite as raw materials, high temperature melting, fibrosis, made of inorganic fibers. Slag wool is industrial slag such as blast furnace slag, phosphorus slag, fly ash as main raw material, after remelting, fibrosis, made of inorganic fibers. The two fiber-processing, can be made into plates, tubes, felt, ribbons, paper and a variety of products, should be used for construction and industrial equipment, pipes, furnace insulation, fireproofing, acoustic, seismic, etc..
