Q:Which plant need to make refractory mould?
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What are the characteristics of magnesium fireproof plate
Plate glass magnesium fire with high temperatures, flame retardant, sound absorption, shock-proof, pest control, anti-corrosion, non-toxic tasteless non-polluting, can be used directly on the painting, direct veneers, available gas nail directly on the tile, the surface has good coloring , high strength, resistance to bending toughness, nails, saw, can be sticky, easy decoration. It can also be made into thermal insulation materials with a variety of compround composite insulation plate.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
Sodium silicate, pure calcium aluminate cement, boric acid
Q:How long does it take for refractory cement to solidify?
1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
Q:can slag tailings be used to be the base materials of refractory materials ?
perhaps not, because it has many pores.
Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
In the construction of high-temperature refractory mortar, the following matters should be noted: 1. Take out the organic fire blocking material and knead it into tha shape of a ball. If the temperature is too low, the blocking material along with the package can be put into 40-70℃ warm water and heated before any other operation. 2. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 3. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 4. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting. The holes should be cleaned up before plugging. Lay, embed, and fill the blocking material into the gap of holes evenly. For larger holes, flame screen can be used as the framework to increase strength.
Q:What is the criterion of entry of refractory clay industry?
Refractory clay refers to clay which has a refractoriness of more than 1580 ℃ and can be used as refractory material and bauxite which used as refractory material . In addition to a higher refractoriness, they can keep the stability of volume under high temperature conditions and have slag resistance and thermal shock resistance and mechanical strength, so they are extremely firm after calcination.
Q:What's the frequently used refractory material?
Refractory material is generally used in industrial departments like metallurgy, glass, cement, ceramics, machinery, hot working, petrochemical industry, power and national defense. Frequently used common refractory: silica brick, semi-silica brick, clay brick, high alumina brick, magnesia brick, etc. Frequently used special refractory: AZS brick, corundum brick, direct-bonded magnesia-chrome bricks, carborundum brick, calcium oxide, chromium hemitrioxide, alumina, magnesium oxide, etc. Frequently used fireclay insulating refractory: diatomite product, asbestos product, insulation board, etc. Frequently used unshaped refractory: ramming refractory, refractory castable, plastic refractory, refractory mortar, gun-mix refractory, refractory coating, lightweight refractory castables, etc.
Q:The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
