Method for producing mineral wool fiber by using high-temperature liquid waste slags of metallurgical furnace as raw material

The invention provides a method for producing a mineral wool fiber by using high-temperature liquid waste slags of a metallurgical furnace as a raw material. The method is characterized by comprising the following steps: discharging the high-temperature liquid waste slags of the metallurgical furnace, allowing the waste slags to flow into a heat insulting electric furnace and keeping the temperature; melting the slags to generate fibers; melting a hardening and tempering agent; drawing and blowing the fibers by using a high-voltage fan; and blowing the generated mineral wool into a wool collecting chamber. The method is simple and convenient to operate; the fiber filaments are smaller than 7 micrometers in diameter, long and good in toughness; sensible heat in the raw material is fully utilized; comprehensive utilization of different industrial waste materials such as copper, lead, zinc, nickel, tin and high-temperature liquid waste slags are realized; the prepared mineral wool fiber is better than rock wool and mineral wool produced by other methods in acid resistance and waterproofness, excellent in technical performance, wide in application and applicable to preparing excellent environment-friendly energy-saving heat-insulating materials; the method disclosed by the invention is relatively low in investment cost, reliable in technology, low in resource consumption, environment-friendly and clean in production and obvious in economic benefits.
