Nitrogen Silicon Carbide Furnace Eye Bricks for Submerged Arc Furnaces
Ferroalloy ore furnace linings are basically carbonaceous linings. Carbonaceous furnace lining has very obvious advantages, but carbonaceous materials have obvious shortcomings in practical applications such as tap holes. After continuous exploration and application, Nitrogen Silicon Carbide Bricks were finally selected as the taphole material. At the same time, it has continuously changed its masonry methods and operating procedures for the use of furnace eyes and has achieved certain success. Ferroalloy Ore Submerged Furnace Lining Nitrogen Silicon Carbide brick manufacturing process principle and advantages and disadvantages Nitrogen Silicon Carbide bricks use silicon carbide (SiC) as aggregate, add industrial silicon powder, stir evenly, and stamp into shape. The thickness should be moderate and not too thick. If it is too thick, the nitrogen permeability will be low and the performance of the product will be reduced. It is nitrided and sintered at high temperature, 3Si+2N2=Si3N4.
