Q:How many refractory materials does the annual output of 1 million tons of coke oven require?
Refractory materials are expensive, and any refractory accident will lead to a considerable waste of production time and equipment, and sometimes even the product itself. The type of refractory material will also affect energy consumption and product quality. Therefore, it is very important to select the refractory material which is most suitable for various applications. While the economic benefits have great influence, refractory material most suitable for some applications need not be used for materials, but can achieve a balance between material installation cost and performance, this balance is not fixed, but with the introduction of new technology or new refractory materials and changing. History has proved that unremittingly seek metallurgical process more reasonable and development, greatly promoted the development of refractories, quickly resolve these problems has become the modern refractory steel technology development is an important element. The content of this article is to discuss a number of factors including these issues and to provide information on how to solve them.
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:What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
Common red brick and refractory brick.
Q:What are included in wall fireproofing material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake.
Q:What are the material requirements of class A fire resistant door ?
What are the material requirements of class A fire resistant door ?
Q:What is special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
Q:Who knows how many poured refactory material are there?
Pouring refractory material can be classified into the followings according to the body density: Heavy (> 2.0g\cm3), medium heavy (1.0-2.0g\cm3), light (0.4-1.0g\cm3); by binding agent: Combination of hydration, chemical binding, condensation, hydration and condensation: Clay, high alumina, silica, magnesia, alumina magnesia, magnesium and chromium, magnesium zirconium, silicon carbide etc.. Clay brick, high alumina brick, bead brick, silica brick, light mullite, alumina hollow spherical brick, oxidation zirconium hollow spherical brick, corundum brick, magnesia brick, magnesia brick, magnesia alumina spinel brick, magnesia chrome brick and so on
Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors can be divided into steel and wood, so fire doors can be divided into fireproof steel door and fireproof wooden door. In fact, fire doors of all classes are divided into steel, wood, steel and wood, and other materials (see GB ). Mainly depending on what kind of material the customers want. The fire door is called class A fire door not because of the material but because of the fire-resistant time. The fire resistant time of class A fire door is not less than 1.2 hours and fire doors as long as meeting this condition can be called class A fire doors . The filling material in class A fire doors is generally perlite, whose difference is in thickness. A few of them will use fireproofing materials like foam core board, vermiculite fireproof board, MC composite material and so on. The thickness of class A fire door is usually 50mm. I hope my answer can help you.
Q:What's the fireproof specification for constrcution external wall thermal insulation materials?
Specification for constrcution external wall thermal insulation materials: Article 1 In order to implement the "State Council opinions on strengthening and improving fire prevention work" (state issued [2011] No. 46), to standardize fireproof design and application of external wall thermal insulation materials of newly constructed, renovated, and expanded civil buildings and to prevent and reduce fire of building external wall thermal insulation materials, this provision is made in accordance with relevant national technical standards and our province real situation. Article 2 When there is no cavity between external wall thermal insulation material for exterior wall and base wall and between decorative layers, the insulation system shall comply with the following provisions: (A) Residential buildings: 1. When the building is higher than 54m, combustion performance of the thermal insulation material shall be A level; 2. When the building is not higher than 54m,combustion performance of the thermal insulation material shall be at least B level. When using B1 level insulation materials, non-combustible materials should be used to make the protective layer, and a protective layer thickness of the first floor of the building should be not less than 10mm, the other floors not less than 5mm; incombustible materials of more than 300mm height should be used to make horizontal fire barrier zone in every floor. (B) Other buildings in addition to residential buildings
Q:What is the limit of fireproof rolling shutter?
Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
