Fire/firecaly brick

Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Linquan series alumina bricks are high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content.

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 are the main components of high alumina bricks?: Sweat is like water mineral alumina bauxite, aluminum ore, magnesite, waves of gibbsite. Anhydrous alumina raw material, such as corundum, alumina, fused corundum. High alumina brick Zhengzhou gold company specializing in the production of various specifications, you can directly ask their technical staff.

Q: Application characteristics of high alumina brick: Load softening temperature. The softening temperature of high alumina brick products decreases with the increase of silica and alkali metal oxide content, but is higher than that of clay brick products, which is about 1420 - 1530 degrees centigrade. Al2O3. The softening temperature of corundum brick with content greater than 95% can reach above 1600 DEG C.

Q: How many cubic bricks does a high alumina brick have?: Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.

Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it: Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.

Q: Can high alumina brick resist carburizing?: The key is to look at the content of Fe3O2 metal oxides (so-called anti carburizing brick generally refers to the content of Fe3O2 less than 1% clay brick and Gao Lvzhuan) just a photo shoot, out for everyone to see, high alumina brick common in reductive atmosphere has been chalking up.

Q: What is spalling resistant high alumina brick?: Spalling resistant high alumina brick is a kind of high alumina brick. Antistripping high alumina brick with high grade bauxite and containing Zr02 synthesis as raw material, according to a certain proportion by high pressure molding system in sintering products, products with anti stripping ability, and have the anti erosion potassium, sodium, sulfur, chlorine and alkali salt, low thermal conductivity and other properties that is the transition zone of cement kiln and decomposition of ideal material with remarkable characteristics, the product is good thermal shock resistance, strong ability to adapt to the environment. It is used in the preheating or decomposing furnace, grate cooler and so on.

Q: How to test the aluminium bricks of high alumina refractory bricks?: Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

Q: What is the apparent porosity of high alumina brick?: Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.

Q: How are the grades of high alumina bricks differentiated?: In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.
