Q:How to do refractory bricks
There are many varieties of refractory bricks, and the pratice of it is similar to ordinary brick practice, but the requirements of equipment and technology will be much higher
Q:What types of refractory bricks are divided into?
middle rank。 A refractory is stronger than B refractory, low rank, the other is refractory, the senior is AB. Shale is hollow, it is not refractory, refractory, advanced, refractory B, there are nonfireproof materials in intermediate and low rank. Three types of refractory A
Q:What are the factors that determine the weight of the refractory bricks?
(5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
Q:Lining of refractory bricks in rotary furnace
The lining now is built with MgO-C brick, the specific time to change it mainly to see the quality and usage of MgO-C brick. A few years ago, the mills are desperately seeking furnace age, some can use thirty thousand furnace, by the way, furnace age of converter refers to the number of steelmaking furnace not time. So now most mills are not simply pursuit furnace age, but economic furnace age, currently furnace age of steel mills around us is mostly in about ten thousand to twenty thousand. In general, the furnace service of the converter is arranged with the overhaul of other equipment. This can realize the synchronous maintenance of various equipment. If the stove is too old but the maintenance is not timely, also is not to replace the lining brick timely, there will be leakage, then the furnace shell and even ring will be damaged, consequences are more serious . The reason is very simple for brick falling off. One is the poor quality of furnace brick,causing brick lining loose, rocking furnace will lead lining brick falling. the other one is the furnace lining brick is pressed too tight in the use procedure and the brick is too thin.
Q:What are the main raw materials of refractory brick and runner brick?
Category of refractory , runner brick mainly is clay brick
Q:can castable refractory replace refractory bricks in rotary kiln?
The heat produced in the welding process will cause local deformation of the rotary kiln, which will affect the dynamic balance, and the construction difficulty in the middle position of the rotary kiln is much larger than that of the refractory bricks. Moreover, the construction quality is not easy to ensure, generally only replace the refractory brick in the kilneye, because the construction of the castable refractory need to weld the anchor
Q:How to wipe off the white paint on the refractory brick (red).
Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
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: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.
