- Q: Refractory net
- The development of the industry of refractory materials is very good, manufacturers are also more and more, especially in the Henan Xinmi side, next to the factory factory, we had visited gold refractory material factory, the scale is very large.
- Q: Is fireclay corrosive?
- No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
- Q: Physical and chemical indicators of various refractory.
- it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
- Q: Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?
- High alumina brick, clay brick, brick and other high-quality refractory products, widely used in metallurgy, building materials (cement and glass), non-ferrous metal smelting, petroleum, chemical, electric power, machinery manufacturing and other industries.
- Q: What type of firebrick does TZ-3 represent?
- It is the standard brick.
- Q: What's the fire endurance of hollow brick?
- This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. This is the maximum limit.
- Q: Who knows the fire resistant level of the rock wool color plate?
- The rock wool color steel rock wool board is used in a area of high ??fire safety requirements. According to "interior decoration of buildings for fire protection design", the color steel rock wool board belongd to level A. Its life is more than 15 years and still can be used when the temperature is up to about 700 ℃, with maximum fireproofing hour of six hours. And the rock wool color plate is a environmentally friendly material, the preferred material in the construction industry .
- Q: What are the specific steps of stirring the steel ladle castable?
- Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.
- Q: What refractories can withstand high temperature above 2100 degrees?
- It depends on refractoriness of refractory materials. The three refractory bricks above is 300 degrees higher than quartz sand in refractoriness. Magnesia brick: Cast corundum brick with greater than 2000 degrees refractoriness should be enough for you to use. But products like quartz sand merely keeps 1600 to 1700 in refractoriness generally. As you described that refractoriness is greater than 1990 degrees, it is feasible to use hearth made by mixing of quartz sand and refractory cement, which can work for some time at 200 degrees. It is also ok to use dolomite brick whose refractoriness is greater than 2000 degrees.
- Q: Which refractory is better for building 1500 degree kiln ?
- High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
