Improvements in brick-formed basic refractory linings for metallurgical furnaces

摘要

A method for lining a metallurgical furnace, such as a crucible furnace, and especially a large furnace, with bricks of a basic lining material in which inter-brick sintering is prevented by applying a sintering- preventing coating at least to the surfaces of each brick which are destined to contact an adjacent brick. The bricks in the layer (2) can be of arcuate form and forced into contact one with another by a layer (3) rammed between the layer (2) and an electrical coil (4). The coating may be magnesium chromite. IMAGE
