$Refractory Castable ASC-6 Used For Iron Runner Of Casthouse$

Q: Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: The cut is relatively transparent if you jam, we have also used silicon manganese alloy

Q: What materials is silicious thermal insulation board made of?: Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Of course the amount of insulation board materials used by different companies is different. In terms of Hua Heng, siliceous insulating boards can be divided into insulating panels for casting slabs and insulation board for intermediate tank according to the usage. The latter one can be divided into liner plate (wallboard, side panels, baseboard) and impingement plate based on parts it is used on. Siliceous insulating panels use quartz sand as the main material and are composited with fiber. Method for manufacturing a silicon insulating panel is divided into semi-dry method and wet method. It is used for casting ingot insulation cap of the killed steel and continuous casting tundish.

Q: What's the function of aluminium dihydrogen phosphate on the refractories?: Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace

Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?: I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.

Q: Does refractory belong to stone, building materials or other?: Refractories belong to organic non-metallic materials.

Q: How long is the fire endurance of the rock wool board?: Hello. The limit is up to 2 hours. Of course such a thing is not desirable.

Q: which kind of refractory is commonly used in the industry: Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary?kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.

Q: Are refractory materials and fireproofing materials the same?: The refractory material and fireproofing material are not the same in the strict sense. Refractories refer to non-metallic materials of which refractoriness are higher than 1580 degrees. Now commonly used heat insulation materials can also be considered as refractory materials. The fire endurance of fireproof materials reaches certain requirements. Its test temperature is 540 degrees. Range of applications for two material are not the same. Refractory materials can be used in high-temperature region as it can withstand high temperature. Fireproof materials can not be used under high temperatures for a long time.

Q: Where is the development of refractory industry?: Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories.
