Q:What are the requirements for refractory materials in heat treatment furnace?

Refractoriness is the property of a refractory against high temperature, which means the temperature at which a refractory is softened to some extent after heating, but not its melting point. According to the degree of refractory, refractory materials can be divided into: General refractories, refractory degree is 1580 to 1770 DEG C; advanced refractories, refractory degree is 1770 to 2000 DEG C; special refractory material, refractory degree is greater than 2000 DEG C.

Q:Difference between low creep high alumina brick and ordinary high alumina brick

The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.

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 is the density of a super high alumina brick and what is the price?

Of course, the transaction price, please choose refractory brick manufacturer is better.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of high temperature refractory brick?

High alumina brick clay brick up to 1700 degrees above 1500 degrees -1750 degrees of magnesia brick and magnesia chrome brick 1500-1650 degrees, I is the production of clay brick, brick my temperature at 1500-1700 degrees. Specific depends on what kiln, brick is only part of it

Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?

All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..

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 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 is fireproof concrete?

A series of concrete with fire resistance and heat resistance is made of Portland cement series as cementing material and heat-resistant material as aggregate. Silicate fireproof heat-resistant concrete with Portland slag cement, Portland cement and water glass as cementing material, broken clay brick, clay, cement clinker, broken high alumina brick as aggregate.

Q:How high can aluminum bricks expand at 80O degrees of heat?

When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
