Specification:
Product characteristics; General use high-alumina brick use yangquan bauxite clinker with high quality combined with clay and additives made from. Product has high refractoriness, good acid and alkali erosion resistance, high temperature strength, good thermal shock stability etc, and widely used in metallurgy, light oil, chemical industry, building materials, machinery, processing, thermal technology equipment of military industry and other industries.
- Q: What are the grades of high alumina bricks?
- According to the size of high aluminum brick is divided into: standard brick, special-shaped brick.
- Q: What is the price of the first grade high alumina brick?
- Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
- Q: The difference between aluminium refractory and magnesia refractory
- Magnesia refractory belongs to alkaline refractory materials refers to refractory products such as magnesia magnesia brick magnesium iron spinel magnesium aluminum spinel magnesia ramming materials and other products of raw materials is the main crystal phase is periclase magnesia products
- 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
- People with the shaft kiln cement clinker kiln, because of small size, low calcination temperature, using only Al2O3 containing a single clay brick is 30 ~ 40%, the rotary kiln was improved in the early Yuan faith this experience, use of high alumina brick and clay brick, from 60s onwards, due to large scale kiln and to strengthen the operation of the high temperature parts of kiln lining, alkaline brick masonry is widely used, the main varieties are: magnesia chrome brick, magnesia spinel brick and dolomite brick.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Forming high alumina brick will be tested on some professional equipment, it is suggested that you can go to the professional testing department to know about it!
- Q: How high can aluminum bricks expand at 80O degrees of heat?
- The expansion of high alumina brick is not only related to temperature, but also related to its material composition. The refractory temperature of high alumina brick is above 1770 centigrade. The temperature of 800 DEG C has little influence on the expansion of high alumina brick.
- Q: How to reduce the harm caused by two times mullite in high alumina refractory material
- Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- 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.
