- Q:What kind of refractory bricks material is best?
- In general, aluminous fireclay brick is used. GB / T 3994-2005 insulating fireclay brick. Bricks with good material are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.
- Q:What kind of material is refractory fiber?
- Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
- Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
- As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene?monomer through free radicals polycondensation reaction. It is a transparent thermoplastic?plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
- Q:which kind of material is chosen for fireproofing window?
- (1) the inside filler material of steel, wood frame should use incombustible material. (2) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (3) steel frame and mound layer can choose galvanized?steel?sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (4) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire. (7) hardware accessories should be tested qualified approved supporting product.
- Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
- I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
- Q:What are the main components of refractory cement?
- Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
- Q:How long is the fire endurance of fire resistant rolling shutter door?
- According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
- Q:How to choose construction external wall thermal insulation and fireproofing materials?
- The width of fireproof partition shuld be greater than 30CM, and the thickness should be the same as total thickness of thermal insulation materials. Fire barrier zone thermal insulation board and base wall should be stuck in whole area. Fire Barrier zone thermal insulation board should be stuck with the assistance of anchor bolt which must press the mesh of the bottom layer. Fire Barrier zone should be set above the door and window, with a distance of less than 50cm between the lower edge of fire barrier zone and the upper edge of window.
- Q:Can anyone say something about what A-level fire-proof decorative material is?
- Now A-level market is very confusing. The major products are material monomer A-level and composite A-level, now a lot of B-level material is wrapped in calcium silicate board. The foam cement overall composite is level A, such as phenolic aldehyde composite, as well as some of the foam paddings, while monomer A-level includes rock wool, ultra-thin insulation panel and the like.. But there are few products with real sound A level qualification. Many manufacturers are playing the edge ball with A-level fire rating examining reports and B-level system detection reports and records, but this situation will not last long, which will soon be clear. I hope the information above can help you. Hope you adopt
- Q:What are the refractory stocks?
- The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.
