Q: What type of firebrick does TZ-3 represent?: Height is 65mm, length is 230mm, and width is 114mm, that is the t-3 firebricks which meet the national standard.

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's the fire endurance of fireproof?panel?: fire endurance of fireproof?panel can reach 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.

Q: What is special refractories?: Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use

Q: Which brand of AAA refractory is good?: Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.

Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?: According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is shorter than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be used. Steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board. As is known to all, steel structure usually will lose bearing capacity usually in 450 to 650 degree, leading to deformation, steel column and beam bending, and be no longer usable at last. Generally fire resistant limit of unprotected steel stucture is about 15 minutes. 1.5 hours;if fire resistance level is level the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. Steel structure an use surrounding concrete (or masonry), fire retardant coating, fire retardant plate and compround structure to achieve the required refractory limit. Hope my answer will help you.

Q: How long is the fire endurance of the rock wool board?: When the average temperature reaches 140 degrees Celsius or 180 degrees Celsius, it starts to lose the fire insulation function.

Q: What is the offer of fire proofing thermal insulation material?: 1. Fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 15 yuan 2. 1260 ceramic fiber cotton thermal insulation panel thermal insualtion aluminum silicate aluminium oxide fireproofing fibre board 20 yuan 3. non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber cotton blanket 28 yuan The above prices are from the Internet and for your reference only. Price may vary according to specific circumstances.

Q: What are fire resistant level standards of class A fire resistant door?: Grade standards: class A fire resistant door is an important part of fire-fighting apparatus, and an important step in the social fireproof work. The quality and use of class A fire resistant door is closely related to the success or failure of the fireproof work.. There are steel and wood for class A fire resistant door materials. Only those whose fire endurance is no less than 1.5h can be called class A fire resistant door. In general, the class A fire resistant door internal material is perlite, and still some are vermiculite fireproof board, foam core board, MCcomposite materials, and other fireproofing materials. The thickness of class A fire resistant door is usually 50mm. In places where there is strict requirements for fireproof?performance, class A fire resistant door is often installed.

Q: How to classify fire resistance rating of brick-concrete structure?: In order to ensure the safety of the building, the fire protection measures must be taken to make it have a certain degree of fire resistance, even if there is a fire, it will not cause too much damage. According to the national conditions of our country, and in the light of other countries standards, < high-rise civil building fire protection design specification > defines fireproof rank of high-rise civil buildings into level one and two; < code for fire protection design of buildings > divides the rank into level one, two, three, four, level one is the highest level, level four is the lowest. Besides that the minimum fire resistance of the building component is specified, buildings of fire resistance rating also specified requirements for combustion performance. Because the component with the same fire resistance limit is different, it is different in the fire.According to our country national standard < building design fire protection code >, the fire resistance rating of the building is divided into four levels. The fire resistance of a building is determined by the combustion performance and fire resistance of building components (such as beams, columns, floors, walls, etc.). Generally speaking, the fire resistance building of level one is a mixed structure of reinforced concrete structure or a mixture of brick wall and steel concrete structure; the fire resistance building of level two is a mixed structure of steel truss structure, reinforced concrete column and brick wall; the fire resistance building of level three is brick-wood structure made of wood roof and brick wall; the fire resistance building of level four is combustible structure which is composed of wood roof and non-combustible wall.
