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 specifications for bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.

Q:What are the characteristics of high alumina bricks?: 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 high-temperature kilns and other energy consuming industries, such as chemical industry, electric power industry, etc.

Q:What are ordinary bricks, refractory bricks, hollow bricks?: Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q:What's the price of high alumina refractory bricks?: Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.

Q:What does refractory consist of?: According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.

Q:In 2016, a few of the traditional refractory materials will be able to survive: From the year 2015 to the year 16 the end of the year, refractories industry presents two kinds of situations: one is a small business, a single product variety and equipment, to meet the demands of both environmental protection and the downstream market, such enterprises are generally in the Qing state inventory;

Q:How to reduce porosity of high alumina brick: High alumina brick used as refractory products in refractory material, has a great application in masonry kilns, insiders pointed out that the quality of high alumina brick general porosity and it has a great relationship! So, how to reduce the porosity of high alumina brick rate is very important!

Q:What are the categories of bricks?: Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels.

Q:Which thermal shock stability of clay brick and high alumina brick is good?: Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products

Q:Can high alumina brick resist carburizing?: The resistance to carburization is not directly related to the bulk density of bricks
