Method for preparing mineral wool

Abstract

The invention provides a method for preparing mineral wool, which includes the following steps: mixing electric furnace smelting clinkers of liquid red soil nickel ore with aluminum donors, and throwing the obtained mixture to obtain the mineral wool. Through the adoption of the method, electric furnace smelting clinkers of liquid red soil nickel ore can be effectively utilized to prepare the mineral wool.

Description

technical field [0001] The present invention relates to the preparation method of mineral wool. Background technique [0002] In recent years, as my country has paid more and more attention to building energy conservation and environmental protection, as a kind of thermal insulation and energy-saving material with excellent performance, the market demand prospect of mineral wool is very broad. At present, most rock wool (a type of mineral wool) is prepared by melting basalt and blast furnace slag as the main raw materials in a cupola. The melting of bulk raw materials needs to consume a large amount of coke, which also increases the production cost of rock wool. At the same time, electric furnace smelting laterite nickel ore to produce ferronickel produces a large amount of molten slag, almost all of which are treated as waste, which not only pollutes the environment, but also increases the cost of waste disposal for enterprises. Since the composition of ferronickel slag i...
