- Q: There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
- High temperature prevention, warmth keeping and heat insulation.
- Q: How to test the various components of the refractory brick?
- It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.
- Q: What is refractory brick? What is refractory clay? ?
- refractory brick----is refractory material with a certain shape and size. According to the preparation process, bricks can be classified into burnt bricks, unburned brick, electric melting brick (fused cast brick) and the refractory insulating bricks; according to the shape and size, bricks can be classified into standard brick, ordinary brick and specific brick and etc. High-temperatured building material and structural material that can be used to build furnaces and various thermal equipments, and can endure various physical and chemical changes and mechanical effects at high temperature. For example, refractory clay brick, high alumina brick, cilica brick and magnesia brick and etc.. Fireclay -- usually refers to a kind of soil clay used for fire the stove and the furnace hearth in folk 1, characteristics and usages: Clay refractory brick is a kind of weak acid refractory material, its thermal stability is good, suitable for hot blast stove, various boiler lining, and flue, smoke room, etc.. 2, product specifications: Standard form, general profile, special shaped and special shaped brick. Physical and chemical properties of clay refractory bricks. The upper limit ---- about 1500 degrees under normal pressure
- Q: Can someone tell me the refractory brick in the boiler mixed with what material to build the wall, and what proportion?
- Go to the refractory factory to buy some refractory clay that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
- Q: Characteristics of refractory bricks
- The ability to resist rapid changing temperature and not to be destroyed is 6, it refers to the change of the volume expansion and contraction in the same temperature change. the porosity is 3, this parameter is very important in its own properties, anti bending strength, but as a manufacturer, you must strictly control the explicit hole through the material unit area of heat flow rate: The main composition determines the quality and characteristics of the refractory material 2: Unit volume weight, good impact resistance, abrasion resistance show good compactness: Also called high temperature load, it begins to deformation temperature, the volume density, we define such a linear change rate is 0 physical and chemical properties is 1: 5, but the heat conductivity coefficient may be large, load softening temperature, porosity: The ability to withstand shear stress is 8, compressive strength: Did not make specific requirements about thermal shock resistant performance: Resistance to anti penetration erosion under high temperature and not destroyed 7: Don't have to explain it, linear change rate, thermal conductivity, slag resistance: Also known as linear?change?on?reheating or the residual line change, if the expansion and contraction of each time is the same: Under the condition of unit temperature gradient, the service life is 4, chemical composition.
- Q: What are the ingredients of brick?
- Artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick. Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and. Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
- Q: the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall
- 9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value
- Q: Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
- They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
- Q: What material are used to burn firebrick?
- Alkaline series of refractory bricks /, can be classified into five types. Refractory bricks are generally made from refractory clay (white clay) or other refractory materials. Refractory brick according to the composition of refractory material, that is, silicon aluminum refractory brick / carbon containing refractory brick / thermal insulation refractory brick/ zirconium containing refractory brick /
- Q: How much refractory material is required for 1 million tons of coke oven
- This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
