英文摘要： Making use of the waste heat of the blast furnace molten slag product insulating material such as slag wool, which pass the mineralogical reconstruction direct fibrosis. The research overcome the technical problem of restricting slag wool production scale to large, which is limited of the energy consumption by melting, and solve the market problem that heat insulating material of inorganic building is difficult to supply for the enhance of fire prevention level of high-rise building. The project will focus on multiple key scientific theories which restrict blast furnace slag direct fibrosis and bonding shape. The main contents include:(1)The mineral phase reconstruction mechanism research of the fibrosis liquid blast furnace slag.(2)The mechanism research of the fibrosis liquid blast furnace slag. (3)The slag fiber bond forming mechanism. (4)The heat compensate mechanism of direct fibrosis of the liquid blast furnace slag. This project research will completely solve the molten slag directly fibrosis forming bottlenecks scientific theory problem:(1)The Influential Mechanism of the Element reconstruction on the liquid blast furnace slag fiber forming, Mineral phase composition and microscopic structure.(2)The Influential Mechanism of the liquid blast furnace slag fibrosis methods on the liquid blast furnace slag f
