Caustic Calcined Magnesite is produced in the Rotary Kiln by sintering raw magnesite at a controlled temperature of 1750 degree centigrade and its chemically inactive. Dead Burnt Magnesite is consume almost exclusively in the production of Refractory Field.

Dead Burnt Magnesia Uses:
1. Refractory Industry for manufacture of Basic Refractory Bricks
2. Manufacture of Ramming Mass composition, Fettling material and Magnesite Mortar
3. It is used in SLAG beneficialness and in SLAG splashing in Arc Furnaces
4. It is also used as a coating material in Steel Industry.

Q:The manufacturing technique of refractory material: Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank

Q:What are the uses of refractory materials of glass furnace?: crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks.

Q:What kind of refractory decorative board has good quality?: Baby Rabbit has excellent refractory decorative board. It once won the Chinese famous brand, and was awarded iconic brand in plywood industry and the most influential integrated service providers of indoor decoration materials . Fireproof?panel is made from body paper(titanium coated paper, kraft paper) in high temperature and pressure through impregnation technology of melamine and phenolic resin. Refractory door slab is made by sticking fireproof?panel on base materials such as density board or chipboard.

Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: There are a lot of silicon manganese alloy manufacturers, production market is relatively large, the manganese content in manganese alloys between 63 to 70 or more common

Q:What kinds of fireproof materials does the safe use?: The fireproof materials of the safe, cement foam. It is often said recently that the safes with cement inside are bad. Actually, it is not like this. Chemical means are taken to make the cement inside safes rise like a leaven dough so as to achieve good insulation. The principle is the cement foam. Fireproof safes with such techniques have good performance in terms of fireproofing and anti-theft. The manufacturing processes of this fireproof safe are highly technical, some safes with poor techniques have problems in quality. Here are some data of the foam cement.

Q:what's the fireproof levels of fireproof and thermal inuslation matertial?: What are the fireproof levels of fireproof and thermal inuslation matertial on the market? how to divide the fireproof levels of fireproof and thermal insulation material?

Q:Urgently!! Refractory problems, online, etc.: The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process

Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?: Pay attention to the performance of the materials, and the use of non oxide materials!

Q:Is there any difference between insulating bricks and refractory bricks? Are there any professional refractories factories that are reliable in the quality and quality of these irritated materials?: Seven characteristics of insulating brick:Insulation and heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.Per square metre weighs only about 1.4 kilograms, reduce the burden of building.Simple production: completely break through the traditional process, greatly shorten the construction cycle.Beautiful: can be modulated into a variety of colors, suitable for Ming outfit.Durable: long service life.

Q:How long is the fire resistance time of the AAAfire resistance rolling shutter door?: How long is the fire resistance time of the AAA fire resistance rolling shutter door?
