- Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- Therefore, the choice and masonry of refractory bricks are of vital importance. If there is a brick kiln kiln off block process of reproduction, is now because of the use of refractory brick kiln material mostly three grade high alumina bricks. The content of AL2O3 is about 55%, of which the content of Fe2O3 is about 2%, which is weak, and the alkali corrosion resistance is a little worse. In a containing three grade high alumina bricks in the composition of AL2O3, Si2O3, and other elements also contain K, Na trace, were the most, thus causing the system of the low melting point is very low, even at 1400 DEG C has been liquid phase, and generate CaAL12O19 limestone and calcium feldspar etc.. Form corrosion loss. Therefore, a long time will cause the loss of block. On the one hand, it may be caused by construction.
- Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?
- The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.
- Q: How are the high alumina bricks fired?
- Generally, the high alumina bauxite is added with a small amount of clay. After being ground, the gas is injected and shaped in the form of slurry by the way of gas attack or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used to replace part of bauxite clinker. Used for lining and thermal insulation of masonry kilns, as well as for areas where there is no high temperature, high melting material erosion and erosion effects. When touching the flame directly, the touch temperature shall not be higher than 1350 degrees.
- Q: What's the price of high alumina refractory bricks?
- Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.
- Q: The cloth blowing is not uniform on the lime kiln refractory brick is damaged it
- Lining 1 yuan to prevent direct damage to the Sindh kiln high temperature flame or air, to protect the kiln carcass; 2, to prevent harmful substances (CO, SO2) erosion of the kiln body; 3, to prevent corrosion, material flow on the kiln body; 4, reduce the kiln temperature, kiln body to prevent oxidation 5, has the function of corrosion; thermal insulation; 6, to improve the coating performance.
- Q: What are the characteristics of high alumina bricks?
- A neutral refractory with an alumina content of more than 48%. Made from alumina or other raw materials of high alumina content; formed and calcined.
- 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: The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina brick, also called high alumina insulation brick. Alumina content of 48% or more, mainly from mullite and glass phase or corundum composition of lightweight refractory. Volume density 0.4 - 1.35g/cm3. Porosity 66% - 73%, compressive strength 1 - 8MPa. Better thermal shock resistance. Usually, a high alumina clinker is added with a small amount of clay. After grinding, it is poured and shaped in the form of slurry by gas generation or foam method, and it is 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 causes breakage of refractory bricks?
- There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
- Q: High alumina brick 80 with which high aluminum cement?
- In order to maintain a reasonable comprehensive lining, should adopt high quality aluminum refractory mud, such as Sichuan resistance card phosphate refractory mud, refractory clay, high alumina refractory mud PA-80 LN-75, if you use the card volume of Sichuan resistant refractory clay masonry, the effect is better.
