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 is streaming fireproof material?: Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.

Q: What are the specifications of fire resistant bag?: Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.

Q: what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q: Who knows the external wall thermal insulation materials fire rating requirements?: The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q: What is refractory cement?: Ordinary portland cement is common cement with relatively high early strength, while refractory cement is low in this regard. Refractory cement is a characteristic cement which can only be used in special projects, not suitable for general engineering. And in the winter, it is not suitable for construction use.

Q: What types does refractory floor include?: It includes ecoplates, chipboard,density board, composite?board, etc. Wherein ECO-plate is solid wood board, and it is environmetanl and healthy. Its nail-holding ability and flatness is much better than that of chipboard and solid wood particle board. After all it is solid wood board. But we must pay attention to whether the eco-board is produced in the original factory. According to our original factory, the board only produced by Treezo Group and Dede board are the original.

Q: Which refractory is suitable for the tunnel kiln?: Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.

Q: What are the new refractories?: Most are ordinary refractories.

Q: What are the refractories for converter?: Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
