Problems solved by technology

However, in the high-temperature thermal slag conditioning process, it is difficult for the slag to mix with the conditioning agent and reduce the temperature, resulting in high viscosity of the slag, and it is difficult to form the silicate system required for silk, which seriously affects the production of mineral wool and the quality of silk, and restricts The utilization of silicomanganese slag has resulted in the environmental protection pressure of silicomanganese production

Abstract

The invention provides a tempering method of mineral wool produced from silicon manganese slag and relates to a tempering method of high-temperature hot-molten slag during the production of building mineral wool from metallurgy furnace slag. According to the tempering process, molten silicon manganese slag produced during the production of silicon-manganese alloy through mine heating method is directly poured into a heating furnace and is heated and subjected to heat preservation, and a tempering agent is added and is uniformly mixed with the molten silicon manganese slag for tempering. According to the tempering method, the molten slag is poured into an electrode of a heat preservation furnace so as to generate fluidity, so that adequate mixing with the added tempering agent is accelerated, and a silicate system is rapidly formed; and the molten slag with proper melt temperature and viscosity and with components meeting wool slag blowing requirements is obtained through the heating ofthe heat preservation furnace, so that the problem that molten slag is difficult to be mixed with the tempering agent so as to be cooled is solved, the performance standard of the mineral wool is satisfied, the mineral resources are saved, and the industrial waste slag is well utilized.

Description

technical field [0001] The invention relates to a tempering method for producing mineral wool from silicomanganese slag, which relates to a high-temperature thermal slag conditioning method in the process of producing mineral wool for construction by using metallurgical slag. Background technique [0002] Mineral wool and rock wool belong to the same type of thermal insulation materials. Compared with other inorganic fiber thermal insulation materials, rock wool has a wide range of applications and has developed into an important thermal insulation material for construction. [0003] Mineral wool is made of blast furnace, ferronickel, silicomanganese and other industrial waste slag as raw materials, and the molten slag is made of silky inorganic fibers by high-speed centrifugal blowing and other processes to make mineral wool. Compared with rock wool, which is widely used at present, mineral wool still has a big gap with rock wool in terms of acidity coefficient, water resis...
