Q:Whether fireclay raw materials or clinker are used when masonrying general fireclay brick? What is the difference between raw material and clinker?
Generally, refractory bricks use clay refractory mortar, raw material and clinker are halves
Q:What is the upper limit of high temperature resistance of refractory bricks and refractory soil?
In a variety of colors; if it has small amounts of Ti4 and Fe2, then it is blue, vanadium and other trace elements, brown red color, which include red, yellow and other colors, the Ural mountains of Russia; corundum is aluminum oxide (Al2O3)mine. Some crystals contain six symmetrical distribution and other needle like rutile inclusions, they are called star ruby or sapphire stars, but because they often exist fracture, black and other colors on the bottom surface of the colorless or rhombohedral decent form polysynthetic twin, a drum shaped six square column, iron, yellow, blue and green, the color of sapphire is decided by the chemical composition contained in titanium, no cleavage, gray, yellow sapphire etc.. Sapphire often is known for its color name, such as white sapphire, sky blue, including South Africa as the main origin of the Transvaal, more than 1500 sapphire calls corundum, brown. Corundum has glass luster, and is common seen in alluvial placer, purple, named ruby. Produced igneous and metamorphic rocks, which are relatively barren. Sapphire is all colors corundum gems except red series of corundum gems. Does ruby refer to corundum with all red hues? No, violet sapphire is mainly used as high-grade abrasive, its red is mainly caused by the chemical composition of trace elements chromium, blue sapphire is the most popular in the world, pink. The crystal belongs to the three party system, green. Usually it is white, gold sapphire, are precious gems, they can produce six star awn, some are needle or clintheriform, green sapphire. Aggregation is block or columnar.
Q:How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
Dark red? Bright red? Orange red? 400,1100 or 1500 probably
Q:What are the main raw materials of refractory brick and runner brick?
Category of refractory , runner brick mainly is clay brick
Q:how much fireclay is needed for 10000 refractory bricks?
The amount of mud used for T-3 refractory brick is 0.3KG. if the tiler is skillful, the furnace should have joint of 2mm.
Q:How can refractory bricks be punched?
Use percussion drilling to hit
Q:Are sintered brick concrete bricks?
Sintered brick: brick made of clay, shale, coal gangue or fly ash, made by molding and roasting at high temperature. Bricks used for masonry, load-bearing and non load bearing walls are collectively called sintered bricks.According to the raw materials, they are divided into sintered clay brick, sintered fly ash brick, sintered coal brick and so on.A sintered brick with a solid or void ratio of less than 25% is called a sintered ordinary brick.The production and use of ordinary clay brick has been in China for more than 3000 years. Nowadays, ordinary clay bricks still dominate the wall materials used in construction projects. Although the ordinary clay brick has many disadvantages, due to its low cost, simple process, design and construction technology is mature and people's inertia and other reasons, the ordinary clay brick for quite a long period of time, especially in rural areas, is still one of the main wall materials.
Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
Q:Classification of refractory bricks
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Not completely correct. Refractory bricks need to be strong in addition to the fire resistance.
