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: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:Why can't build refractory brick behind the skew block?
refractory is heat expansion and cold contraction, it is also called refractory brick, can resist high temperature up to 580-770 degrees. Mainly used for the smelting furnace. faint yellow or brown, when it is high temperature, it will squeeze toward the center. Refractory material made of refractory clay or other refractory raw materials. the shortened form of fefractory brick is brick. vault will be extrusion deformation. Refractory material with a certain shape and size
Q:What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
Exterior wall uses red brick, preheating zone uses lightweight high aluminum bricks, burning zone uses mullite, cooling zone uses ordinary refractory bricks
Q:The matching ratio of masonrying refractory bricks cement
When building refractory bricks, use matching chamotte, do not use cement
Q:What are the main raw materials of refractory brick and runner brick?
Types of refractory bricks are divided into low-grade and high-grade. generally, siliceous, semi siliceous and high aluminous runner brick brick have higher requirements. If it needs to contact melting in high temperature molten steel directly, then it is high alumina(the main raw material is clinker of bauxite with high alumina, corundum( brown corundum and white corundum), the refractoriness is high, lower than 1580 DEG C temperature, but the actual using temperature reaches 1630 DEG C
Q:when to replace the worn refractory bricks in rotary kiln?
But also depend on the other conditions of the furnace, many aspects should be understood, not only to see the degree of wear!
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:What is the best color of refractory brick
Clay refractory brick: Yellow and deep yellow; acid-proof brick: Red, high alumina brick Beige, a little white; square viewing brick: Yellow, red, white, gray, brown, brown, nigger-brown and so on; color is just one aspect of the selection of refractory bricks, it mainly is to see the inherent quality
Q:How aluminium oxide becomes a entity from the the form of powder (such as a ball, a stone, or a refractory brick)?
Just like the process of making steamed bun from flour. Ball milling ---in the auxiliary material to make the slurry --- suppress the body --- high temperature calcination
