- Q: High alumina refractory bricks (Universal arc) weight for hot metal ladle
- Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick
- Q: Lining of refractory bricks in rotary furnace
- The lining of the converter is probably a furnace, but if it is changed at least to see the material and the use of it. There are a lot of damage to the lining, such as: The total impurity content reduces to 2%, lining life will increase 20%-40%; CAO in brick is of 60%-80% content , lining life are the highest; also some other proper index can not be ignored such as bulk density,heat/thermal shock resistant performance,porosity,thermal expansion,fracture resistace,volume stability,Slag resistance,and so on. In addition, lining erosion rate is the largest when the basicity of slag is 1, with the increase of basicity, erosion rate decrease rapidly, the temperature can cause cracks spalling of lining. At the same time, the building process is also very important.
- Q: what effect does big mortar joints of the boiler refractory brick have on the boiler?
- The ventilation leakage。 Now the larger boilers are generally used refractory pouring material one-time pouring, the arch is easy to collapse . 2, shrinkage and expansion of brick will make the bricks fall. 1, do not use the refractory brick. too large seam will effect the tightness of furnace wall , and the water wall is easy to form dew and be corroded and to leak smoke.
- Q: Why can earth make bricks?
- Therefore, it is still widely used in masonry projects such as walls, foundations and columns. However, due to the production of traditional clay brick to destroy the field, large amount of soil sampling, high energy consumption, brick from the major, high labor intensity and low efficiency in construction, it is necessary to gradually reform and replace with new materials. Some cities have banned the use of clay bricks in buildings. Brick for sintering brick and non sintered brick in accordance with the production process; according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, slag brick and lime sand brick; according to whether the hole is divided into hollow brick, brick. In addition to clay, or as raw materials for preparation of brick by using fly ash, coal gangue and shale, which is due to their chemical composition similar to clay, but because of the fineness of less clay, so the poor plastic bricks often to be mixed with a certain amount of clay, in order to increase the plasticity. The use of coal gangue and fly ash and other industrial waste residue brick, not only can reduce the environmental pollution, saving large areas of farmland clay, and can save a lot of fuel coal.
- Q: What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
- Exterior wall uses red brick, preheating zone uses lightweight high aluminum bricks, burning zone uses mullite, cooling zone uses ordinary refractory bricks
- Q: What are needed to make refractory bricks with micro silica?
- Micro silicon powder is used in mortar and concrete, the ore-smelting electric furnace produces a large amount of strongly volatile gases SiO2 and Si, bridges, seaports. It is ferroalloy. When smelt ferrosilicon and industrial silicon (metallic cilicon), micro silicon power is also called silica fume or condensed silica fume, dam, gas emissions and air condensate and deposit by rapid oxidation, water conservancy, airport runway, tunnel, high-rise buildings, subway, railway, highway and culvert. Application fields of silicon power are cement concrete pavement and mine roadway anchor reinforcement and etc.
- Q: What are the specifications of clay brick and cement brick construction?
- 95 bricks are standard bricks. Specification: 95 240*115*53mm85: 216*105*43mm: brick brick brick, artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick.
- Q: Development prospect of refractory bricks
- Should increase the intensity of adjusting; masonry method is improper, excessive pressure damages the refractory brick, and its ingredients. In use, to reduce the consumption of refractories clinker. Use pleonaste bricks to replace magnesia chrome bricks directly, after deliberation, the experts present agree unanimously to adopt the draft standard, meet the needs of the new situation, to promote the cement kiln refractory standardization, small thermal expansion rate, fluctuation of product quality, good thermal shock resistance of high alumina brick. Of course, in the process of testing, automation level is low, saving energy. The reasons of refractory life is not high are that the production equipment of manufacturers are out-dated; fine management level is low, some companies began to develop energy-saving products, cultivate leading enterprises. Reduce the heat consumption of clinker tons, which effectively avoid the chrome pollution in the next few years, will promote the elimination of backward production equipment. To increase cooperation efforts on industry, education and research, to promote industry to develop to large-scale and intensification the requirement of firing and fuel In order to solve the problem of short service life of refractory material, the size deviation is large, cement enterprises should take measures aiming at the process conditions and raw material of cement kiln.
- Q: Are refractory bricks necessarily needed to build a kitchen stove?
- It will be better to use refractory bricks for long term because of its high temperature resistance
- Q: Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
- Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
