- Q:What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Natural element minerals. Of minerals produced by an element (elementary substance). There are about 90 natural elements in the earth's crust, accounting for 0.1% of the total weight of the earth's crust. Can be divided into metal elements, mainly platinum and copper, silver, gold, etc., non-metallic elements, carbon, sulfur, etc., half metallic elements, arsenic, bismuth and so on.
- Q:What's the weight of the refractory bricks?
- Fireclay refractory bricks: 3.4kg-3.8kg - according to the quality of raw materials, prices ranging from 1 yuan to 2.7 yuan, high alumina refractory brick: three, high aluminum in 3.9kg or so. Ordinary T-3 firebrick weight calculation method: 230*114*65*2.2/2.1.
- Q:What's the difference between a well type annealing furnace and a box type annealing furnace?
- 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.
- Q:How are the grades of high alumina bricks differentiated?
- In China, the content of Al2O3 in high alumina brick is usually divided into three categories: I, etc. - Al2O3 content > 75%; II, etc. - Al2O3 content is 60 to 75%; III and so on - Al2O3 content is 48 ~ 60%.
- Q:What are the requirements for Rubble backfill height?
- Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
- Q:What are the alloy wear resistance materials?
- Alloy wear-resistant materials from different manufacturers different components in Beijing Naimo company as an example, the following alloy wear resistant material:1: Ni Cr alloy wear-resistant material2: chrome carbide wear-resistant material3: high manganese alloy wear-resistant material4: tungsten carbide alloy wear-resistant material5: nickel tungsten alloy wear-resistant material
- Q:Is glass wool inorganic thermal insulation material?
- The use of glass wool, glass wool is usually used as raw materials of various types of insulation materials, such as glass wool board, glass wool, glass wool, glass wool pipe, can be used in the following areas:1) roof insulation, cold protection, sound-absorbing materials; 2) building exterior wall insulation and cold protection; 3) entertainment places, theaters, television stations, radio stations, laboratories, sound absorption treatment.
- Q:Introduction of high alumina brick
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.
- 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
- Q:What are the high temperature refractory mortars made of?
- Siliceous mud, mineral composition and chemical composition is similar with silica, excellent corrosion resistance, water glass slurry, drying shrinkage, but also can be used for bonding fiber products, sealing furnace wall.
