Q: What are the fire protection standards of insulation materials?: 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: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.

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: What are the construction measures of refractory material in winter? Please descriptive briefly.: Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.

Q: what's the varieties of thermal insulation material with A level fire?rating?: the main A level fireproof material is rock wool now (note:it is rock wool not mineral wool). A1 level fireproofing, now the largest producer is Taishi rock wool Co., Ltd.; hope my answer can help you, thank you.

Q: Manganese steel belongs to refractories: Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are

Q: How to make the service life of refractory materials longer?: Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.

Q: What are the materials used in refractory material processing?: Refractory materials generally refer to inorganic non-metallic materials with a refractoriness of more than 1580 degrees. It includes natural ore and a variety of products made by a certain process according to certain requirements. It has certain high temperature mechanical properties and good volume stability. It is the necessary material for all kinds of high temperature equipment. Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..

Q: Classification of porosities in refractories and their effects on properties: Effect of apparent porosity on properties:The porosity is high, the volume density is low, the structure become more loose, generally low strength, corrosion resistance worse (slag infiltration and erosion along the hole toward the inside), but to improve the thermal shock resistance (resistance to thermal shock and not damaged).

Q: How do refractory materials apply into pyrophyllite?: Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
