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 are the fire protection standards of insulation materials?: This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.

Q: What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?: The rapid development of the technology of continuous casting refractories so the corresponding development and improvement in variety and quality, continuous development of refractories for the continuous casting billet continuous casting production and quality have a significant impact. Especially, the completion and operation of Baosteel have greatly promoted the technological progress of refractory materials in China, and the refractory materials for continuous casting have made great progress both in variety and in quality.

Q: how about the performance of aluminum silicate fire proof thermal insulation?: aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.

Q: How to prolong the furnace age of Induction furnace by using fireproof materials?: magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.

Q: What is the particle size of boron carbide for refractories?: 0.3-0.5% is OK, but also with other additives, such as aluminum powder, silicon powder, magnesium alloy powder and so on. To achieve good results.

Q: Fire insulation and fireproof insulation board materials What is the difference in performance?: Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.

Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?: You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into

Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?: Looking for refractory materials network, you can conduct online transactions, funds guaranteed
