Fused magnesite chrome sinter

Finished Fused Mag-Chrome is made of high-quality chrome concentrate and high purity magnesite at accurate proportion, adjusting Cr2O3 content from high chrome to low chrome, in order to achieve low impurity content and high bulk density, as well as meet different needs. after molding into brick with our clincker, it is widely used in secondary refining device for RH,VOD,AOD and non-ferrous metallurgical furnace.

Q: What's the fire?retardant material of roller shutter fire resistance door ?: Core board of fire door materials are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smooth surface, unibody. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute.

Q: Concrete composition and function of magnesia bond used in refractory: Mainly high purity magnesia powder and silica fume, in accordance with the 4:1 ratio of the mixture, that is, we often use in the castable MgO-SiO2-H2O binding system! Compared with cement, the content of CaO is lower, the high temperature strength of the product is increased, and the slag corrosion resistance of the product is increased!

Q: Is there requirement for radiation indicator in refractory?: All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon?dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.

Q: What are the insulation fireproofing materials?: Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.

Q: What defect does fused cast refractories have ?: What defect doesfusion-cast refractory material have ? In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are sidewall block and brick kiln bottom. I hope my answer can help you.

Q: Is aluminium oxide refractory material?: Calcination aluminium oxide is refractory material of fine performance made from pure aluminium oxide through high-temperature calcination. It can be made into coarse-grained material, fine-grained material, fine powder and micro powder, which can be made into pure jade burnt products. For example, corundum brick, lightweight corundum bricks. It can also be made into a variety of unburning products together with other materials, such as carbonaceous materials. For example, aluminum carbon and aluminium zirconium carbonaceous materials. As for the production of unshaped refractory material, there are more species. It can be corundum, rubing grain, corundum spinel and can also be added into other materials to improve specific performance. It isn't limited to high-alumina castable refractory and it can be castable refractory, ramming?mass, impressionable plastic material, gunning mix and refractory mortar.

Q: What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?: STP has a certain chance to self-destruct. After the sealing layer is damaged, the property will be bothered. When filling the foam glass, burst foam cement and low-strength glass fiber, the structural requirements are very high with big spraying limitations. As everyone knows that rock wool absorb organic matters, and the government do not allow us to use self-insulation, so it is not the mainstream with too low adoption rates. In fact the owners shouldn't worry about this problem. Since the developers have installed it for you, it is useless to worry about it. The other is that for those who want the original balcony closed up, if you want to shovel the original balcony wall insulation, you must pay attention to ask the construction team before you start. Because it is common that the cold bridges formed thereby will cause water seepage and moisture condensation in the balcony.

Q: What types does refractory floor include?: There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.

Q: What are the best refractory materials in 2,400 Celsius degree?: It is the purpose that decides what kind of materials you should use. What you have said is 2,400 Celsius degree, right? It is about the fire resistance of the material or the required temperature of it?

Q: Who knows about the types of Dalian thermal insulating and refractory materials?: There are mainly following types: rock wool series, rubber and plastic series, glass wool series, mesh series, ventilation series, mortar series, extruded sheet series, geothermal series, insulation supporting pin series, glass silk cloth series. I hope my answer can help you.
