Product Introduction
Product Details
Production method:
Lightweight high-alumina thermal insulation brick is a lightweight thermal insulation brick with an Al₂ Oover content of not less than 46%. It is a high-temperature heat-resistant and heat-insulating refractory material. It uses refractory clay clinker as raw material, plastic clay as binder, and an appropriate amount of combustibles or foaming agent are added. It is formed by a brick press and then sintered. It has the characteristics of high strength, good thermal shock stability, small change of re-burning line, small thermal conductivity, energy saving and heat insulation.
Product details: Lightweight high-alumina brick is a lightweight thermal insulation brick with an Al₂ Oready content of not less than 46%. It is a high-temperature heat-resistant and heat-insulating refractory material. It uses refractory clay clinker as raw material and plastic clay as binder., Add an appropriate amount of combustible or foaming agent, form it by a brick press, and then sinter it. Lightweight thermal insulation bricks are generally used in the thermal insulation layer of various high temperature kilns and are used as thermal insulation materials.
Product characteristics: light high alumina brick its high porosity, low volume density, good thermal insulation performance, is widely used in a variety of industrial furnace internal refractory brick and ketone body between the space of thermal insulation filling material, to reduce the kiln heat loss in order to obtain high energy efficiency. It has the advantages of high strength, good thermal shock stability, small change of re-burning line, small thermal conductivity, thermal insulation and so on.
Light high alumina bricks are widely used: suitable for blast furnace, hot blast stove, carbon baking furnace, carbon calcination furnace, coke oven, steel barrel, casting system, boiler, cement kiln, glass kiln and all kinds of kiln lining and thermal equipment.
