In applications of high temerature industries, there is a must demand for fire bricks. Among so many kinds of refractory products, customers always have problems on specific types of fire bricks. Today, Kerui offers a complete guide on different types of fire bricks.
Different Chemical Compositions of Fire Bricks
Kerui has customers from all walks of life around the world. But they all have a common feature, that is, high-temperature kilns are used in business. These high-temperature furnaces may be used to smelt steel, non-ferrous metals, molten glass, or make cement, generate electricity, and more. As an essential material in high-temperature kilns, customers will purchase a large number of fire bricks from Kerui Refractory. Kilns for different purposes have specific requirements for the performance of refractory bricks. For example, cement kilns need magnesia bricks with strong alkali resistance, and glass kilns need silicon-aluminum bricks that are resistant to acid corrosion for the inner wall.
Now I’d like to list complete types of fire bricks with different chemical compositions and their features:
- Types: clay brick, high alumina brick, mullite brick, corundum mullite brick, corundum brick, andalusite brick, sillimanite brick and so on.
- Features: alumina bricks are neutral refractory bricks. It has good chemical resistance. Customers can use this brick in a lot kinds of high temperature furnaces, except for furnaces with extremely strong chemical corrosion.
- Types: magnesia brick, magnesia calcium brick, magnesia carbon brick, magnesite chrome brick, magnesia alumina spinel brick, magnesia iron spinel brick and so om.
- Features: as a kind of basic refractory material, magnesia brick has good resistance of alkaline composition.
- Types: silica refractory brick, alumina silica brick, silicon carbide fire brick, alumina silicon carbide brick, silicon nitride bonded silicon carbide brick.
- Features: silica brick is a kind of acid brick. This brick has better chemical resistance of acid furnace. For example, customers in glass industry, non-ferrous industry will choose silica brick as lining of kiln.
Different Shapes of Fire Bricks
- Types: 230mm×114mm×65mm;
- Features: in general, professional refractory brick manufacturers usually have strong production capacity. This also means that they will have enough standard bricks in stock. This size is the most convenient option if your business has an urgent need for bricks and the standard brick size fits well in your kiln.
- Types: knife-shaped bricks, ax-shaped bricks, wedge-shaped bricks, two-piece bricks, four-piece bricks, etc.
- Features: the above-mentioned common firebrick shapes have made some changes on the basis of standard bricks. The production of these bricks is also relatively efficient. These common brick types are not only affordable, but also fit the size of the kiln when used, improving the economic benefits of customers.
- Types: anchor bricks, runner bricks, flow steel bricks, checker bricks, rod hole bricks, preforated bricks, arch foot bricks and so on.
- Features: custom-shaped refractory bricks can be better made into shells and linings of industrial kilns, etc. For example, the anchor brick that Kerui is good at can be embedded in the refractory lining to play the role of anchor and connection. Special shaped fire bricks can bring higher economic value to customers.
Different Fire Bricks Especially for The Industry
- Types: AZS refractory brick for glass furnace, silica brick for clay brick for garbage incinerator/blast furnace, fire brick for carbon roaster and so on.
- Features: in fact, these industry-specific refractory bricks overlap to some extent with the previous two classifications. The highlight of customized fire brick is to better maintain the operation of the customer’s kiln. On the whole, the use of refractory bricks for specific industries can reduce subsequent maintenance and replacement and bring higher economic benefits.
The above are all types of refractory bricks summarized by Kerui. We sincerely hope that every customer can benefit from it and understand what type of refractory bricks they really need.
