Low Creep Fireclay Refractory Brick Heat Insulation High Temperature Fire Resistant Clay Refractory Bricks for Furnace
Product Description
Low Creep Fireclay Refractory Brick Heat Insulation High Temperature Fire Resistant Clay Refractory Bricks for Furnace are made of clay (including shale, coal gangue and other powder) and processed by sludge, molding, drying and roasting.
Low Creep Fireclay Refractory Brick Heat Insulation High Temperature Fire Resistant Clay Refractory Bricks for Furnace are made of local materials, cheap, durable, and have the advantages of fire prevention, heat insulation, sound insulation, moisture absorption, etc., which are widely used in civil construction projects. Scrap bricks can also be used as aggregate for concrete. In order to improve the disadvantages of ordinary clay brick, such as small size, heavy weight and high soil consumption, it is developing towards light weight, high strength, hollow and large size.
Low Creep Fireclay Refractory Brick Heat Insulation High Temperature Fire Resistant Clay Refractory Bricks for Furnace were mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.

Performance characters of Low Creep Fireclay Refractory Brick Heat Insulation High Temperature Fire Resistant Clay Refractory Bricks for Furnace:
The Al2O3 content of Chinese clay is generally above 40%, while the Fe2O3 content is less than 2.0 ~ 2.5%.At high temperature, the clay brick is slightly acidic and it can resist the corrosion of acid slag and acid gas, but of low resistance to alkaline matters. It is of good thermal performance and good thermal shock resistance.With the increase of Al2O3 content, the thermal stability is better than that of silicon brick and magnesium brick.
Packaging
Wooden pallets with plastic film or according to your request. 1.Strong packing will protect the goods from any possible damage during transit. 2.Solid packing and overall stuffing can prevent the cases from vibration and jarring. 3.We must take necessary precaution that the packing can protect goods from pilferage or rain. 4.We can confirm that we take every possible precaution to ensure that our products reach our customers all over the world in prime conditon.
