Specifications

We can supply Insulation firebrick, alumina hollow ball brick, acid resisting brick, refractory brick, high alumina brick.

Insulation firebrick Detailed Product Description :

Insulation firebrick , the most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.

Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.

Insulation firebrick :

Using big vibrating table and adopting special castables, the company produces furnace large fireclay blocks with vibrate moulding technology. The physical and chemical properties and appearance of the blocks have exceeded the national standards. The resistant ability to molten glass of the products is better than that of fanditional casting process products and ramming products . the products are especially suitable to build the bottom of furnace, cooling and working end side wall of glass furnace.

Insulation firebrick Typical Application :

Lining of hot-surface of industrial furnaces as carbon furnace, cracking furnace, heating

furnace for oil refining, roller kiln, tunnel kiln.

Back lining insulating layer of industrial furnace as glass tank kiln.

Deoxidizing atmosphere furnace.

Q: How much is the bending temperature aluminum silicon carbide brick for torpedo car: The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.

Q: What is fireproof concrete?: Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.

Q: Is there a big difference between two high alumina brick and one high alumina brick?: The difference between the two kinds of high alumina bricks is great. I perennial in Zhengzhou was responsible for the production and sale of colt refractories

Q: What is the heat preservation material used in a laboratory furnace?: Asbestos, high alumina brick, or carbonized silicon are often used.Thermal insulation materials are generally used to guide heat coefficient less than or equal to 0.2 of the material. Thermal insulation material development is very fast, and in industry and building the use of good insulation technology and materials, often can get twice the result with half the effort. Each ton of mineral cotton insulation used in the building saves one ton of oil a year.

Q: Introduction of high alumina brick: Made from alumina or other raw materials of high alumina content; formed and calcined. High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining.

Q: What are the grades of high alumina bricks?: High alumina brick according to the aluminum content is generally divided into: super high alumina brick, a high aluminum brick, two high alumina brick, three high alumina brick

Q: What is the density of a super high alumina brick and what is the price?: Super high alumina brick, alumina content of 80% bricks, bulk density of 2.7g/cm3 or more, the factory price of about 1900 yuan

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material

Q: Are there any differences between insulating bricks and refractory bricks?: As the name suggests, the main role of insulating brick is used to preserve heat and reduce the loss of heat. Such as: Molai S; and the firebrick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.

Q: How to reduce the harm caused by two times mullite in high alumina refractory material: Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
