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's the price of high alumina refractory bricks?

Their refractory bricks are of good quality and low ex factory prices. Special high alumina refractory brick factory price of 1900 yuan / ton, a high alumina brick factory price of 1650 yuan / ton... This price applies to standard size, size 230*114*65mm, more products, prices go to see.

Q:What is the difference between metal compounds and metal solid solutions?

Solid solution refers to the alloy phase in which the solute atoms are dissolved into the solvent lattice and remain solvent type. A crystalline substance consisting usually of atoms or molecules in which a chemical substance is dissolved as a base; other substances are found in alloys and silicate systems; also present in polyatomic substances. The mixture can be treated as a solution when the crystal structure of the solvent can be stabilized and homogeneous after addition of solute. Some mixtures can form solid solutions in many concentrations, while some mixtures do not form solid solutions at all.

Q:Use of high alumina refractory bricks?

Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.

Q:How to make refractory bricks and boiler wall adhesion more firm?

Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry

Q:Which is better, the soft core or the hard core?

The wire has two kinds of hard core and soft core, the hard core line is only one wire core, and the soft core line has a plurality of wire cores. For the same sectional area, the 7 core is more than the more than 30 core. There is a difference in use. Generally used for DC is the use of hard core line, because of its small line consumption; and for communication, we should use soft core line, but also in order to reduce its line consumption

Q:What is the heat preservation material used in a laboratory furnace?

Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".

Q:Is glass wool inorganic thermal insulation material?

Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.

Q:What is the price of the latest thermal insulation material?

Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.

Q:What are the common thermal insulation materials for thermal conductivity?

The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.
