- Q:What's the difference between a high aluminum brick and a clay brick, two?
- Light clay brick, refractory material is a kind of high porosity, low density, low thermal conductivity of refractory material, refractory materials called lightweight refractories, it includes insulating refractory products, refractory fiber and refractory fiber products. Heat insulation refractory material is characterized by high porosity, general 40%-85%, low volume density, lower than 1.5g/cm3, low thermal conductivity, generally lower than 1.0W (m.K). The utility model has the function of heat insulation of an industrial furnace, and can reduce the heat dissipation loss of the kiln, save energy, and can reduce the quality of the thermal engineering equipment. The mechanical strength, wear resistance and slag resistance of insulating refractory material are poor, and it is not suitable for the load-bearing structure of kiln and direct contact with slag, burden, molten metal and other parts.
- Q:How much fireclay is needed per cube refractory bricks?
- Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
- Q:Shale brick and clay brick? Answer before you know it
- The clay brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing.
- Q:What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
- When the production of sintered clay brick, brick baking in an oxidizing environment and a kiln, produce red brick; if the first brick in an oxidizing roasting, and then watering stuffy kiln, the kiln to form reducing atmosphere, makes the three brick red iron oxide is reduced to a high oxygen low iron and preparation so blue. The durability of brick brick than good.
- Q:What is the perservation method for refractory bricks used for cement kiln?
- The place should be dry and ventilated. Remember that the packaging can't be damaged. If is not used for a long time, put desiccant next to the bricks. Then have thermoplastic packaging again, it won't get damp. Under normal circumstances, it can be stored for 3-5 years and won't be hairy
- Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
- It can't be the surface of coal, at least it is coal seed.
- Q:Clay brick, red brick, always fried brick how to do?
- Red brick fired, try using a bubble, if not burst, you can use.
- Q:Is the thickness of the kiln lining and the refractory brick the same concept?
- This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
- Q:Can mud and salt be used as refractory materials
- Definitely not, the refractory temperature of soil just is more than 800 degrees, it belongs to eutectic mixture
- 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.
