Method for preparing light insulating brick from refined manganese slag and forming production line of light insulating brick

Abstract

The invention discloses a method for preparing a light insulating brick by using refined manganese slag and a forming production line of the light insulating brick, and belongs to the field of insulating materials. The light insulating brick comprises the following solid raw materials in percentage by weight: 15-20% of refined manganese slag, 30-45% of silica sand, 10-15% of silicon fireclay, 10-15% of mullite, 20-25% of perlite and 20-30% of sawdust powder. The preparation method comprises the steps of raw material preparation, uniform stirring and mixing, slip casting, drying and sintering.According to the invention, the occupied area of refined manganese slag stacking generated by ferroalloy production can be alleviated, the problem of environmental pollution is solved, the fire resistance of the thermal insulation material is improved, the problems confronted by the ferroalloy field and the thermal insulation material industry at the same time are overcome.

Description

technical field [0001] The invention relates to a method for preparing lightweight insulating bricks and a molding production line thereof, in particular to a method for preparing lightweight insulating bricks by using refined manganese slag and a molding production line thereof, belonging to the field of insulating materials.
