Specifications
refractory ladle lining brick
1) Good thermal shock resistance
2) High-temperature endurable
3) Good thermal insulation
Description:
1. Good acid stability
2. Good thermal performance
3. Good thermal shrinkage
4 Good resistance to abrasion and corrosion
Advantage:
Fire brick is refers to the Al2O3 content is 30% ~ 40% aluminum silicate.Clay brick is made of soft clay and 50% and 50% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of 1300 ~ 1400 ℃.Clay brick belongs to the weak acid refractory products, can resist acid slag and the erosion of acid gases, the alkali resistance ability is a bit poor. Clay brick has good thermal shrinkage.
- Q:Corundum, high alumina and fireclay refractory difference is what
- In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
- Q:What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Sulphide. A total of more than 200~300 kinds, followed by the type of silicate minerals, the weight of 0.25% of the crust. Chang Fu is an important nonferrous metal deposit, which is an important source of copper, lead, zinc, antimony and so on. It is of great economic value. The main features are: metal luster, color, streak is deep, low hardness, good thermal conductivity, than the major. Another feature is that because sulfides are often associated with magma, it is very easy to oxidize under the surface supergene action. Except for pyrite (6 ~ 6.5 hardness), the hardness is very low. Such minerals pyrite, chalcopyrite, galena, FeS2 CuFeS2, PbS, Sb2S3, stibnite sphalerite molybdenite, cinnabar HgS MoS2.
- 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:What is the content of free silica in the refractory bricks of high alumina bricks?
- Refractory powders are not rich in free silica in varying degrees
- Q:What are the alloy wear resistance materials?
- According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
- Q:Is glass wool inorganic thermal insulation material?
- The use of glass wool, glass wool is usually used as raw materials of various types of insulation materials, such as glass wool board, glass wool, glass wool, glass wool pipe, can be used in the following areas:1) roof insulation, cold protection, sound-absorbing materials; 2) building exterior wall insulation and cold protection; 3) entertainment places, theaters, television stations, radio stations, laboratories, sound absorption treatment.
- Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?
- Top burning type hot blast stoveIt means that the burner is installed on the top of the hot blast furnace of the iron making equipment, and it does not need a special combustion chamber in the vault space. It is also called a non combustion chamber type hot blast stove.
- 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: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 kind of material is the general metal case?
- Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.
