Q:Classification of refractory bricks
Q:What is refractory brick? What is refractory clay? ?
Fire clay refers to the light pouring material, raw materials adopt light porous clinker, bauxite, cenosphere, silicon dioxide ultrafine powder and alumina micropowder. Use calcium aluminate cement CA-80 as binder. Refractory brick is burned from stone powder and clay put in 1300 degrees' kiln
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:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:What is the refractory brick in silicious model?
Adding appropriate amount of mineralized agent to promote the transformation of quartz in the body into phosphorus quartz. Smaller coefficient of thermal expansion. Also used in high temperature bearing part of hot blast stove and acid open hearth furnace, refractory materials and ceramic kiln, kiln vault and other load-bearing parts, thermal shock resistance variation. High temperature strength. the glass furnace is burnt in 1430 to 1350 degrees Celsius in the reducing atmosphere. use natural silica as raw materials. True density 2. more than 93% of silica content. generally there is no crystal type transformation above 600 degrees celsius. With acid slag erosion and sediment chamber regenerator performance, soaking furnace, open hearth furnace. there is more crystal type transformation below 600 degrees celsius. mainly used in coking chamer of coke oven and partition of firebox. acid refractory material made of high thermal shock resistance, large volume change, square quartz and a small amount of residual quartz and glass box . Long term use at high temperature without deformation
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
Q:Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
If the temprature is below 1200 degrees, the clay castable refractory can be used at what temprature, or use lightweight clay thermal insulation bricks. Thus, the furnace body is not easy to crack. The service life will be long.
Q:What are the release agents of refractory bricks?
Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.
Q:What kind of refractory brick is suitable for 1400 degrees shuttle kiln?
Corundum mullite
