- Q: Lining of refractory bricks in rotary furnace
- About 7000~10000 furnace in steelmaking, the level of maintenance and management of each plant is different! Refractory thinning relates to safety issues (equipment and people safety). i am not clear about zinc smelting! Zinc smelting may use rotary kiln! blow the zinc powder into the kiln.
- Q: what is consequence of high load and soft low of high alumina refractory brick ?
- softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
- Q: What is the meaning of special shaped refractory brick material n-2b?
- In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
- Q: Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
- It's certain that refractory brick is better.
- Q: What is the difference between clay brick, glazed tile and brick?
- Glazed tiles are bricks that have been burnt and glazed on the surface of bricks. Is the surface of glaze firing together, the main body consists of clay and clay two, back out of the red clay, abaxially grayish white porcelain clay fire. Glazed tile surface can do a variety of patterns and patterns, than polished brick color and pattern rich, because the surface is glaze, so wear resistance is better than polished brick.
- Q: th choose of different refractory bricks in the rotary?kiln
- According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
- Q: Are refractory bricks poisonous?
- Zirconium minerals are often associated with other minerals in the mining, because the bricks are basically burned under more than 1 thousand degree. But some of the bricks contain heavy metal elements chromium. Some of the brick contains zirconium, the vast majority are very safe, and heavy metal elements have a certain toxicity, there are many kinds of refractory bricks that the nature is very stable, and the associated minerals are generally radioactive
- Q: Can you direct the clay brick walls embryo
- Times are different, where there is no modern calcination process. With glutinous rice water in the soil, but glue well, but there is no comparable with cement and other building materials. Not long, can not withstand weathering.
- Q: cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?
- Portland slag cement 325 or 425. Use phosphate cement or aluminate cement. Use portland cement. You can also use the fragment and power of waste refractory brick or fireclay brick or aluminous refractory brick.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
