Q:What material is good for refractory brick?
1, silicon aluminum refractory bricks mainly include the following.(a) is the main varieties of acidic silica brick, refractory brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.(two) clay brick is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.(three) the mineral composition of high alumina refractory brick and high alumina refractory brick is corundum, mullite and glass phase. The raw materials are high alumina and sillimanite natural ore. They are also made of fused alumina, sintered alumina, synthetic mullite and calcined alumina in different proportions with clay. It is produced by sintering process. But the products are casting brick, brick, brick fused grain and unshaped refractory brick. High alumina refractory brick is widely used in iron and steel industry, non-ferrous metal industry and other industries.
Q:What's the use of refractory bricks?
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, ordinary brick, specific rotation. 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:Is the wall around the fire area using a firewall? What's the difference between a fireproof brick and a regular brick?
A cuboid with stone walls, with mud firing, mostly red, commonly known as "red brick", there are "blue brick". The size of China's standard clay bricks is 240 x 115 * 53mm. The purpose of this size is to ensure that the length and width of the bricks are 4:2:1 (including the width of the 10mm seam). The thickness of brick to brick brick due to multiple titles, length is 240mm, so the thickness of a brick wall called "24" wall thickness of brick and a half wall called "37" wall thickness is the half brick wall is also known as the "one or two wall". Use bricks online to compare some extreme jokes.
Q:What is the face brick
You should be talking about refractory bricksThe refractory brick brick. Referred to as refractory material has a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick, refractory insulating bricks (Rong Zhuzhuan);
Q:How can the silica in zircon sand be removed during the smelting of zirconium corundum?
Fused zirconia corundum brick is pure alumina and zirconia containing silica 65%, about 34% of the zircon sand in electric furnace melting after internalization into moulds cooling and the formation of the white solid, the petrographic structure by zirconium corundum and plagioclase eutectoid and glass phases, from the phase is eutectoid zirconium corundum and plagioclase phase, glass phase filling between their crystallization.
Q:Zirconium corundum 25 content or 40 content, how to distinguish in appearance?
The fused zirconia corundum brick is mainly made of fused zirconia and corundum. ZrO2-Al2O3-SiO2 three element system fused brick, containing Al2O3:40% to 50%, ZrO2:30% to 50%, SiO2:10% to 17%.From the point of view of data analysis, there is no radioactive substance in it, and it will not cause harm to the human body.
Q:What are the forming methods of refractory materials?
Casting molding is suitable for casting brick, electric melting brick and so on. And the machine press forming is the most widely used. The common refractory brick, clay brick and other sintered brick are adopted this method.
Q:What is the weight of the refractory bricks?
Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
Q:What are ordinary bricks, refractory brick, hollow bricks?
Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
Q:Just what is in the furnace material?
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..
