- Q: Which thermal stability of clay bricks and high alumina bricks is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials. The product has the advantages of high temperature, little creep, strong corrosion resistance and good thermal shock resistance, and is suitable for large and medium-sized hot blast stoves.
- Q: What types of building blocks do you have?
- 1. the use of the different parts, building bricks into bricks, floor brick, brick, brick arch shell, brick brick chimney and sewer.2. different building performance, building bricks into bearing brick, brick, brick, non bearing engineering insulation brick, brick, tile, acoustical tile and other flowers.The use of 3. different materials, is divided into building brick clay brick, shale, coal gangue brick, fly ash brick, slag brick, lime sand brick etc..4. according to the shape, the building brick can be divided into solid brick, microporous brick, porous brick and hollow brick. Ordinary bricks and special-shaped bricks, etc..
- Q: Are sintered brick concrete bricks?
- Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick;According to the production process can be divided into sintered brick and non fired brick, in which non fired brick can be divided into compressed brick, steam brick and autoclaved brick;With or without holes, ordinary bricks, porous bricks and hollow bricks can be divided into ordinary bricks.
- Q: How to do refractory bricks
- Sorting materials -- mixed?material - molding - drying - firing embryo
- Q: What are the reasons for the production of waste in the formation of fireclay bricks?
- The reasons for the production of waste when form fireclay bricks: Tile size is unqualified. This is due to the mold installation is not firm, the template transfers when molding; if the amount of material being added fluctuates largely, also can cause the body size changing. Ji Yangon Chi lie charge generation layer containing decyl poke pull and crack. The molding operation does not according to the principle of the light first and the thick later. At the initial pressure, the air doesn't releases, which causes the elastic aftereffect by repressing. Too much mud water, uneven mixture and inequal template all can make the body produce layer crack or crack. Twist. The template is used for too long, the template deforms, so raw brick deforms, the amount of water is too large, brick naturally deforms, causing the body twist. Miss edge and angle. Because of poor plasticity of mud, particles segregate, feeding back corner is not real, the body will appear side missing and angle modulation phenomenon. Bias voltage. Due to the deflection of the die head or the uneveness of mold bottom. Loose。 Due to insufficient feeding amount or insufficient pressure times.
- Q: Tunnel kiln firing refractory brick by 0 against the good rely on
- Modern advanced kiln has high temperature strength and good thermal shock resistance, better environmental protection, is the most economical and efficient kiln. (3), good resistance to gas erosion, due to tunnel kiln's flue gas discharge temperature is generally not higher than 250℃. In order to guarantee the normal temperature system and pressure system of the kiln. Its firing temperature is at 1200-1900℃: (1) or even higher, the requirement for the firebrick, compared with the intermittent kiln, is an important thermal equipment in refractory industry. It is a kind of energy-saving kiln. Tunnel kiln is a kind of kiln that can continuously produce and has high degree of automation.
- Q: What are the properties of clay bricks?
- Clay brick is very important. It can make clay brick not only with high refractoriness, but also can be used in many high temperature thermal equipment. The brick brick has better resistance to hot and cold, and the water cooling can reach 10~25 times at 850 centigrade. Clay brick can resist weak acid slag corrosion, the resistance to alkaline slag is slightly worse, increasing the content of Al2O3, can improve the ability of alkali resistance slag.
- Q: How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?
- 1, classify according to the smelting method : Open-hearth?furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...
- Q: What mud is the refractory brick made of?
- Firing with refractory clay, the main component is AI2O3
- Q: what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
- you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
