- Q: How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
- The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.
- Q: How long is the duration of fire resistance of hollow glass magnesium board
- Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- The fire resistance rating of the aluminium-plastic?panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic?Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.
- Q: What is the interior fireproof thermal insulation material?
- polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- The combustion performance of materials could be divided into: A( noninflammability), B1(flame retardancy), B2(flammability), B3(inflammability). Building materials are divided into four ranks according to these properties. 1. In accordance with Code for Design of Building Fire Protection(GBJ16-1987)(revised edition in 2001), fire hazards in producing and storage can be divided into five types. In Fire Prevention Code of Petrol Chemical Enterprise Design(GB50160--1992)(revised edition in 1999), classification of fire hazards is also achieved according to the hazards of materials that have been using, producing and storing. Measures in prevention of fire explosion could be taken from the perspectives of fire separation, fire resistance level of structures, allowable floors, safe evacuation, and fire extinguishing facilities based on different levels of fire hazards. 2. Four fire resistance rating of buildings are listed in the book Code for Design of Building Fire Protection. And specific stipulations are made to the fire resistance of main elements of buildings, such as bearing walls, beams,pillars, and floors. When designing a building, if permitted, refractory materials of high-rank should be adopted in those buildings which have high potential fire hazard and a lot of combustible material and valuable equipment. While making sure fire resistance rating, the duration of fire resistance of each elements should meet its requirements.
- Q: Does refractory belong to metallurgical auxiliary materials?
- Refractory includes metallurgical auxiliary materials.
- Q: how long is the fire endurance of plasterboard?
- fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
- Q: What's the A class fireproof and thermal inuslation matertial for external wall?
- First, external wall thermal insulation material: 1. silicate insulation material; 2. glue powder polyphenyl granule; 3. cement cystosepiment with the use of steel wire gauze (polystyrere); 4. extruded sheet; Second, roofing materials: 1. xps extruded sheet; 2. EPS foam board; 3. perlite and perlite brick; 4. vermiculite and vermiculite brick; Third, materials for heating power and air conditioners: polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Fourth, steel structure material: polystyrene, extruded board, polyurethane board, glass cotton lap felt, etc.
- Q: What are the specifications of refractory kilns ?
- There several points need to be noted ① selection of body material. The refractory lining of the front kilneye turns gelid and hot rapidly and frequently, so the temperature is in the range of 800 ℃ ~ 1250 ℃, allowing it to withstand wear of the cement clinker and corrosion of the cement base. The body material of castable refractory must be chosen according to its service conditions, in order to ensure that it is cheap and easy to use. ② the selection of admixture. Shapeless refractory materials are typical in-situ reaction refractories. Therefore choosing admixtures is very important and must ensure workability, baking performance, and excellent material properties. Admixture for Kiln refractory castable includes dispersants, accelerators, plasticizers, sintering agent, bulking agent and antidetonant. Materials of sintering agent are animate clay, zirconite, titanium dioxide and Peng compounds. Such substances produce a certain amount of mullite crystals, zircon phase, titanium aluminate crystal and inconsistent melting compounds (2Al2O3 ? B2O3), etc. under the operating temperature and in situ reaction. They are accompanied by volume expansion and microcracks, enabling it to compensate for the sintering shrinkage, so that the casting material can have sintering strength, corrosion resistance and good thermal shock resistance. In summary, the refractory castable material for the rotary kiln shall be determined in accordance with its service conditions. It is recommended that clients should also communicate with technical personnels and sales staff about some facts of the rotary kiln when buying it, so that they can get the satisfying rotary kiln.
- Q: Where is the development of refractory industry?
- The rapid development of continuous casting technology of its related @ China @4 honing refractories develop and increase 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.
