Q: How much is the bending temperature aluminum silicon carbide brick for torpedo car
High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
Q: What is the heat preservation material used in a laboratory furnace?
Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt 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'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: What is the content of free silica in the refractory bricks of high alumina bricks?
In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
Q: Difference between low creep high alumina brick and ordinary high alumina brick
The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012
Q: Which is better, the soft core or the hard core?
When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.
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: Corundum, high alumina and fireclay refractory difference is what
They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.
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: Does the chimney have high acid resistance?
The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred.
