Q:What kinds of minerals are there in the five major categories of ore crystal chemistry?: Sulphide. A total of more than 200~300 kinds, followed by the type of silicate minerals, the weight of 0.25% of the crust. Chang Fu is an important nonferrous metal deposit, which is an important source of copper, lead, zinc, antimony and so on. It is of great economic value. The main features are: metal luster, color, streak is deep, low hardness, good thermal conductivity, than the major. Another feature is that because sulfides are often associated with magma, it is very easy to oxidize under the surface supergene action. Except for pyrite (6 ~ 6.5 hardness), the hardness is very low. Such minerals pyrite, chalcopyrite, galena, FeS2 CuFeS2, PbS, Sb2S3, stibnite sphalerite molybdenite, cinnabar HgS MoS2.

Q:What are the characteristics of high alumina bricks?: High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.

Q:What are the high aluminum bricks made of?: The amount of refractory mud accounts for about 6% of the brick weight

Q:What is the density of a super high alumina brick and what is the price?: Of course, the transaction price, please choose refractory brick manufacturer is better.

Q:In 2016, a few of the traditional refractory materials will be able to survive: The other is in large enterprises and individual has the unique advantage of the small enterprises, with independent technology system, production equipment advanced, there are certain funds set up to deal with risk, timely reform, such enterprises compared to a few years ago the productivity and sales or have declined, but overall is still in the stage of production increased steadily.

Q:How to reduce porosity of high alumina brick: When proportioning, the ratio of coarse to medium to fine is 4:2:4, and the maximum particle size should be no more than 5mm. The mixing order is as follows: first adding coarse particles, then adding sulfite pulp waste liquid, premixed 3min, then adding high aluminum fine powder for mixing. The operation process is coarse and fine particles added in sulfuric acid with crushed pulp waste.In order to reduce the porosity, our company suggested that the single-sided pressure changed to double-sided pressure instead of double-sided pressure, the number of strikes should also vary according to the amount of feeding. If the kiln is fired, the location of the fire hole shall be adjusted so that the middle part is dense, the edge is thin, and the door near the kiln is properly encrypted so that the temperature difference between the furnace top and bottom and the temperature difference between the inside and outside are not greater than 20 degrees.

Q:What refractory material does cupola lining use?: A class of inorganic nonmetallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.

Q:What is the standard size of high alumina brick?: The country has laid down a number of criteria for the use of refractory bricks to unify market demand.

Q:What are the common thermal insulation materials for thermal conductivity?: Aerogels are known to be the lightest solid materials in the world. It is made of nanometer silica aerogel as main material and is compounded by special process. The utility model has the advantages of high temperature resistance, low thermal conductivity, small density, high strength, green environment protection, waterproof and non inflammable performance. At the same time, with excellent sound insulation and shock absorption performance, it is now widely used in metallurgy, chemical, national defense, aerospace and other fields, is an indispensable high-performance insulation materials.

Q:What causes breakage of refractory bricks?: Refractory brick is a non metal mineral products can be used in the high temperature of 1550 DEG C under belongs to a class of inorganic, used in high-temperature furnace lining materials as protection kiln, which causes damage, usually have these points.Furnace temperature is not clear, there is no corresponding choice of refractory bricks.Physical impact, abrasion and erosion cause damageChemical factors, especially chemical industry, should be made of refractory bricks, which should be resistant to penetration and erosionIV: products from the factory when the factory did not pass the quality inspection standards
