FAQ
Q1: How do you control the products quality?
A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.
From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis
Q2: What`s the lead time for my order?
A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.
- Q: Scheme of cement kiln replacing 40 meter refractory brick kiln
- If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
- Q: What is the material of refractory brick used in the high temperature zone of the kiln?
- The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
- Q: In tunnel kiln, what is the meaning of refractory proportion 2.0?
- The proportion of refractory bricks is related to the density.
- Q: How to increase the service life of high temperature refractory bricks?
- The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
- Q: which kind of refractory bricks do coke oven and oxtongue brick belong to ( ) A, silica?brick B, clay brick C, high alumina brick
- Beef tongue is to regulate the flow of gas, gas flow is not the same, so is the temperature, so choose the temperature resistance brick which is clay brick only.
- Q: What kind of refractory brick is suitable for clinker production line of 2,500 tons?
- Silicon carbide composite brick, series of refractory casting material, etc.. In addition to choose above refractories, suggested to put the thermal insulative alkali-resistant clay bricks or ordinary clay brick on the front and back kilneyes, use high strength alkali-resistant clay bricks or alkali resistant castables for arching the roof , insulating brick vault series: use direct- bonded magnesia-chrome brick in burning zone and high alumina brick in decomposing belt. if it is cement kiln then use skilled production line of 2000 tons, combined with silicon carbide brick
- 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
- Q: why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
- There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
- Q: What are the advantages and disadvantages of clay refractory bricks?
- The clay brick refractory brick and be roughly the same, up to 1690~1730 DEG C, but the load softening temperature is 200 degrees Celsius above the low brick. Because clay bricks contain crystalline Mullite with high refractoriness, they contain nearly half of the amorphous glass phase of low melting point.In the temperature range of 0~1000 DEG C, the clay brick volume increases with temperature uniform expansion, linear expansion curve approximates a straight line, the line expansion rate is 0.6%~0.7%, about half of the brick. When the temperature reaches 1200 degrees Celsius and then continues to heat up, the volume will begin to shrink from the maximum expansion. The residual shrinkage of clay brick results in the cracking of masonry joints, which is a major drawback of clay bricks. When the temperature is above 1200 degrees, the low melting point of the clay brick gradually melts because the particles are very close to each other due to surface tension, resulting in volume shrinkage.
- 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.
