Note:

Q:What materials mix mortar to build walls (with bricks)? The more burned the harder: Refractory mortar

Q:What are the application of used refractory brick pieces?: It can be produced into refractory bricks again, as long as the quality is good. It is much more cost-effective than buying Bayerite.

Q:Can mud and salt be used as refractory materials: Definitely not, the refractory temperature of soil just is more than 800 degrees, it belongs to eutectic mixture

Q:Where are clay bricks or cement bricks?: Cement brick is the use of fly ash, cinder, coal gangue, slag, chemical residue or natural sand, sea mud etc. (more than one or several kinds of raw materials) as the main raw material, made of cement coagulant, a kind of new wall materials by high temperature calcination made called cement brick.

Q:What material is sk-34 on the refractory brick: Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products

Q:What are the differences between sintered bricks and refractory bricks?: Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss

Q:How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?: 1, classify according to the smelting method : Open-hearth?furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...

Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?: They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem

Q:How about clay bricks?: Fired ordinary brick is one of the indispensable building materials in production and life, but its quality is not good or bad in the absence of professional equipment. Now to introduce a little trick:According to the main raw materials for clay brick, shale, coal gangue and fly ash brick. Mainly in our local clay brick. According to the compressive strength of weathering resistance of radioactive material and qualified brick, according to the size deviation, appearance quality, efflorescence and lime burst into superior products, first-class products, qualified three quality grades.

Q:How many bricks, mortar and how much wear and tear does one side of the clay brick masonry need?: The loss rate of mortar is 1%, so the total consumption of mortar is 0.212M3*1.01=0.214M3
