development of slag woolWANG Xu1，YUAN Shou-qian1，LI Hai-chao2

The application and the specific process of slag wool are introduced. Specific applications include length slag wool fibers, slag wool and phenolic resins general slag wool products can be used for heating equipment and piping. But insulation of various slag wools is achieved in different conditions. Moreover, slag wool acoustic board can be widely used in fields such as construction and engineering decoration. Raw melting technology include cupola melting, furnace melting, electric arc furnace melting; fiber injection molding process include injection, centrifugation, centrifugal blowing. Finally, it illustrates the necessity of the development of mineral wool.
