Q:The United States of our brick anti-dumping duties?
At present of our brick anti-dumping rate is 73.10%
Q:High temperature refractory material?
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, the refractory material used for special occasions.Now the definition of refractory materials, has not only depends on whether the refractoriness at 1580 DEG. Refers to the current refractories used in metallurgy, petrochemical, cement, ceramics and other production equipment with inorganic non-metallic materials.
Q:Glass kiln brick for physical and chemical indicators?
Glass kiln with high quality silica brick with silicon oxide content, low melt index, mainly used for glass kiln crown, parapet, wall hanging, small furnace arch superstructure and regenerator.
Q:Semisilica brick interpretation
Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.
Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
Heating calcination is the best way to extend this sort of impurity removal. Remove impurities
Q:Because of the recent relates to this industry, by way of learning to name for all raw materials, I hope knowledgeable friends exhibitions, thank you.
Classification of chemical components of refractory materialsAccording 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:Physical solid waste disposal
Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
Q:Physical solid waste disposal
The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
Q:The introduction of silica brick
The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass
Q:Which material is good for furnace refractory?
Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment.
