Firebricks Description
High alumina insulating fire brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory,which has such advantages as high porosity, small volume density,good insulation effect,high mechanical intensity,small thermal conductivity and long service life.For various industrial kilns&furnaces,it is a kind of essential refractory for energy saving and temperature preservation.This series of High Alumina fire resistant brick are made of selected high alumina bauxite, kaolin caly,hollow microsphere as the mian material.By shaping at high pressure and sintering at high temperature.

Firebricks Application
High alumina bricks are commonly used in blast furnace,hot blast furnace,the roof of electric furnace,teeming ladle,rotary kiln,regenerator etc.

Firebricks Features
.Low thermal conductivity
.Excellent acid and base slaging resistance
.High refractoriness
.Excellent thermal shock resistance
.Excellent mechanical strength

Q:What kinds of minerals are there in the five major categories of ore crystal chemistry?: Natural element minerals. Of minerals produced by an element (elementary substance). There are about 90 natural elements in the earth's crust, accounting for 0.1% of the total weight of the earth's crust. Can be divided into metal elements, mainly platinum and copper, silver, gold, etc., non-metallic elements, carbon, sulfur, etc., half metallic elements, arsenic, bismuth and so on.

Q:How to test the aluminium bricks of high alumina refractory bricks?: Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!

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:What are the specifications for bricks?: In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

Q:Can high alumina brick resist carburizing?: It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling

Q:What is fireproof concrete?: According to the different properties of fire resisting and heat resisting concrete, they can be divided into silicate, aluminate, phosphate, sulfate, chloride, sol and organic substance, fireproof and heat-resisting concrete, etc.. The following are mainly used silicate, aluminate, phosphate, sulfate fire, heat-resistant concrete.

Q:What are the requirements for Rubble backfill height?: Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.

Q:What's the difference between high alumina refractory bricks and high alumina refractory bricks?: High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.

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: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.
