Coke furnace silicon bricks are mainly used in the heat storage room, oblique road, charcoal room, combustion room, top of the furnace, and bottom of the furnace.
Anti stripping high alumina bricks are referred to as anti-stripping bricks or anti-stripping refractory bricks. Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
The heavy parts of the chrome-zirconium mullite composite bricks are made of high-purity sintered mullite, high-purity chromium oxide, high-purity zirconia, and Guangbai mud as the main raw materials, and the light part of the raw materials are made of 47 mullite, kyanite, Bleaching beads, coke gemstones and Guangxi white mud are the main raw materials
The refractory pre -production is the category of irregular refractory materials, also known as the prefabricated block of the pouring materials, and the irregular refractory prefabricated block.
Yuying Refractory produces a complete set of refractories for electrolyzers, and the new impermeable bricks are used in conjunction with impermeable castables
Brown corundum refractory brick is made of fused corundum as the main raw material. It is formed by high pressure and fired at high temperature. It has high thermal shock stability, low porosity, low expansion, good resistance to melt vapor and gas erosion, and excellent oxidation resistance. Dimensionally accurate advantages.
Refractory wet mud used to block the iron outlet can be divided into two categories: water cannon mud and waterless gun mud. On large and medium -sized blast furnaces on high top pressure and high degree of smelting.
