The high strength insulation board for steel ladle is non-toxic and non-asbestos. Its heat insulation effect is excellent. It won't release harmful gas during the process of heating. With low thermal conductivity, the product has the properties of high temperature resistance and high pressure endurability. It's mainly used in the equipment of steel ladle, foundry ladle, tundish and torpedo car in the steel making plant, which can achieve the functions of heat insulation and preservation, energy saving and prolonging the lifetime of steel ladle with the cooperation of firebrick and refractory castables.

The high strength insulation board for ladle can also be used in other equipment in iron and steel plant, it can also be used in the equipment of reheating furnace, annealing furnace, rotary kiln, carbonization furnace, bell-type furnace, continuous annealing furnace, blast furnace, converter, hot metal mixer, coke oven, sintering furnace, electric furnace, continuous casting furnace  and induction heater. In petrochemistry industry, the product is mainly used in reheating furnace, cracking furnace and pipeline system. While in non-ferrous metal industry, this kind of high strength insulation board is used in the equipment of ladle for aluminum, tundish, launder, bell-type furnace, ingot mold, metal delivery system, distribution bin and casting bin. In ceramic industry, the product is mainly used in tunnel kiln, rotary kiln, shuttle kiln, body of kiln and pipeline. In cement industry, it's mainly used in rotary kiln. In kiln, the product is often used as furnace lining, heat insulation back lining and furnace insulation zone.
