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:How to test the aluminium bricks of high alumina refractory bricks?
Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
Q:What are the high aluminum bricks made of?
It's OK to use corundum bricks and alumina hollow ball bricks to build a furnace,
Q:High alumina brick 80 with which high aluminum cement?
Which kind should be chosen should be determined according to the conditions of use, life expectancy and cost control. By the way, the quality of masonry is also very influential.
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: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:What is the difference between high alumina brick and clay brick?
Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
Q:What is the standard classification of high alumina bricks or high alumina bricks?
High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
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 difference between T3 refractory bricks or high alumina refractory bricks?
High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick
