Specifications

1.high refractoriness
2.low creep and liner change
3.stability in high tempreture
4.low heat conductivity , low bulk density

High alumia hollow ball refractory brick is one type of refractoy productions which has high alumina content above 84%, which insure the production high refractoriness and stability in high tempreture. While through special producing process and treatment, the micro hollow ball gives this prodution low bulk density and high porosity.

This type of high alumina refracory is widely used in many industries, such as the steel smelt industry/cemen manufacture industry/glass smelt industry/themoelecticty industry and so on. The refractoy production will help the enterpraises to reduce the pollution and energe exhaust,to supply a safer working enviroment to the employees.

1. Applicatons of the high alumina refractoy brick

The high alumina refracory brick is widely used and installed in different equipmnts, such as the steel blast furance/ hot blast airheater furnnce/glass kiln/cement kiln/lime kiln and so on.

Q: What are the specific raw materials for plastic pallets?: With excellent mechanical properties, its strength and elasticity are higher than HDPE, and it has good flexural fatigue resistance. It has good heat resistance and good chemical stability. Besides being concentrated by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents. The high frequency insulation performance of polypropylene is excellent because of its almost no water absorption, so the insulation performance is not affected by temperature.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: RT3 series trolley type resistance furnace is a national standard energy-saving cycle type operation furnace. It has super energy-saving structure, adopts fiber structure and saves electricity 30%. Exclusive production of composite high aluminum nails group, car anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, without the basic installation, placed on the ground floor can be used. Mainly used for high chromium, high manganese steel castings, ductile iron, roller, steel ball, 45 steel, stainless steel quenching, annealing, aging, and various mechanical parts heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high temperature control accuracy, furnace temperature uniformity. 4, a high degree of automation, simple. 5, PID programming can be used to set, fully automatic operation. 6, good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electricity, ships, paper, mining, medicine, central heating and other industrial sectors. With the development of social productive forces, its application in various industries is more and more widespread. Two, pitannealingfurnace (for example: flange heat treatment furnace) use: the furnace for metal parts, such as ring of equipment heat treatment at rated temperature: the furnace is composed of furnace body and a movable furnace cover and control system.

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: The T3 in T3 refractory bricks refers to the model indicating that the refractory brick model is T-3, and that the corresponding T-3 model is 230*114*65 (mm)

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: How much is one ton / ton of high alumina refractory brick?: The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012

Q: What are the requirements for refractory materials in heat treatment furnace?: The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.

Q: How are the grades of high alumina bricks differentiated?: High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%

Q: How to reduce the harm caused by two times mullite in high alumina refractory material: Prolong the sintering time and adjust the aluminum content of the high alumina brick.

Q: Use of high alumina refractory bricks?: Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.

Q: What is the high temperature limit of refractory bricks and refractory soil?: Refractory bricks are stone powder and clay paste. They are fired in a kiln of 1300 degrees. The upper limit is 1500 degrees above normal pressureRefractory bricks - refractory materials of a specified shape and size.
