General Information of Fireclay brick RN40

Our corporation produces a comprehensive range of Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Fireclay bricks are the final result of blending excellent fused alumina and silicon as the main raw materials with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Feature of Fireclay Brick RN40

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining

Low apparent porosity, and low Fe₂O₃ content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion

Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?: Portland slag cement 325 or 425. Use phosphate cement or aluminate cement. Use portland cement. You can also use the fragment and power of waste refractory brick or fireclay brick or aluminous refractory brick.

Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?: The life of refractory bricks in rotary kiln is generally short.

Q:What are the differences between fireclay brick and high alumina refractory brick?: One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting

Q:what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?: Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.

Q:The advantages of using alkalinty refractory brick?: Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln

Q:what type of refractory bricks does TZ-3 stands for ?: Standard brick

Q:MU10 what are the non clay solid bricks?: Clay solid brick with clay and is needed by adding admixture as raw materials, solid bricks by water mixing, molding, high temperature calcination made, mainly used for masonry bearing and non bearing wall, wall materials is a kind of widely used.

Q:the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall: 9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value

Q:how heavy are boiler of six tons plus refractory bricks?: The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material

Q:What raw materials can be added to fireclay brick to respond to the urgent cold and urgent heat?: The effect of adding andalusite is better

Our products are mainly mullite brick, high alimina brick acid-resistant refractory brick, phosphate abrasive brick and andalusite brick, with annual output of 20000 tons heavy refractory, the tunnel kiln with 80m in length is mainly for manufacturing of top quality refractory, such as corundum products, alumina products and spinel products. In order to promote sustainable development, we will insist on scientific development.
