Q:Ask for help about the phase of refractory material
Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.
Q:What problems should we pay attention to in the use of fused zirconia corundum brick (fused zirconia corundum brick) in glass furnace?
The expansion curves of fused cast AZS brick at 1000 DEG C near a crystal anomaly, its internal changes of ZrO2 crystal are reversible, with large volume change, therefore, products containing ZrO2, should not be used in the temperature of 1000 DEG C, often have sharp fluctuations in the position. When baking the kiln, the temperature can not be too large at 900~1150 degrees centigrade. Generally, the temperature can not exceed 15 degrees /h, and the temperature should be raised steadily. Some parts to prevent the cold, with other brick protection, to prevent explosion.
Q:How much is a refractory brick?
This question is too general, refractory bricks according to the use of the environment and industry, there are a variety of materials, a variety of specifications, prices vary greatly.
Q:What is the difference between corundum and high alumina?
The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.
Q:What does refractory consist of?
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:Wave tile and throwing glaze, tile which good?
These two tiles have their respective advantages and disadvantages, in fact, to say which kind of good, mainly depends on the decoration of personal preferences and the location of the shop. If it is only the shop wall, then design and pattern rich whole glazed tile is good, it can make the room impressive, improve decorative effect, make the decoration style to fit the characteristics of his personality. In addition, clean up is relatively easy, not easy to contaminated with oil stains and other pollutants. If it is laying floor tiles, tile Douglas suggested the use of tiles, tiles of good antiskid effect, water absorption rate is relatively low, so the kitchen toilet bathroom and other wet places is not easy to water seepage, improve the convenience of life.
Q:What can zirconium sponge do for those industries?
Zirconium metal, also known as sponge zirconium, silver gray metal, the appearance of steel, shiny; melting point 1852 points, sub points, boiling point 4377 density 6.49. Zirconium is easy to absorb hydrogen, nitrogen and oxygen; zirconium has a strong affinity for oxygen; at 1000 DEG C oxygen dissolved in zirconium can make its volume increase significantly. Zirconium is relatively stable in the air; powder zirconium is easy to burn; fine zirconium wires can be ignited by matches; at high temperatures they can be combined directly with dissolved oxygen, nitrogen and hydrogen.
Q:What material is used in an iron smelting furnace?
In fact, refractory refractory ah is special ceramic frequently used AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials.
Q:What are the refractory materials?
Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, there are refractories for special occasions.
Q:What kind of rock is corundum produced?
Aluminum oxide (Al2O3) mineral. Due to Mohs hardness of up to 9, mainly used as high-grade abrasives. The crystal belongs to the three party system, a dolioform six square column, some are needle or plate. Aggregates are massive or columnar. Usually white, gray, yellow and other colors. If a small amount of Cr3+ is red, a ruby is called;
