Q:How to divide fire resistant level of fire door?: The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire?compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof?staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.

Q:Who knows the classifications of magnesia refractory?: They can be devided into two major categories of fettling magnesite grain and magnesite products. They can be divided into fettling magnesite grain, magnesia?brick, magnesia-silica brick, magnesia-alumina brick, magnesium-calcium brick, magnesia-carbon brick and other varieties according to the chemical compositions and purposes Its performance is greatly affected by CaO / SiO2 ratio and impurities. The load softening point and thermal shock resistance of high purity magnesia brick are much higher than those of the general magnesia bricks. It has high refractoriness and good resistance for alkaline slag and iron slag, which is an important kind of advanced refractory material. Magnesia products are mainly produced by sintering, and sintering temperature is generally between 1500 ~ 1800 ℃. Besides, chemical binder can be added to make unburned?bricks and unshaped refractories. Mainly used in open hearth furnace, electric furnace, oxidation converter, non-ferrous metal metallurgy furnace, cement kiln and calcining kiln for basic refractory.

Q:Ask some questions about refractories: Application: it is suitable for blast furnace tapping system.

Q:What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?: 1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.

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.

Q:What are the application of old refractory bricks?: It can still be used as refractory bricks or refractory. The quality of auxiliary material is not as good as bauxite.

Q:What are the requirements for fire?rating of construction suspended ceiling material ?: In fireproof design of all parts in interior decoration, fireproof design of suspended ceiling is the most important. Because the flame is burning up in fire and the suspended ceiling is the first and most direct part to test fire; at the same time, it has a direct impact on the evacuation. Therefore, in indoor suspended ceiling decoration design, fireproof work should be considered fully. Code of fire prevention design of interior decoratio of buildings has detailed provisions for fireproof?performance of indoor suspended ceiling materiial of different civil buildings. Suspended ceiling (sprung roof) refers to the top decoration of a house. Suspended ceiling, an important sub-project in construction decoration project, and the hidden layer of electrical equipment, ventilation and air condition, communication and fireproof, alarm pipelines, etc. has the functions of thermal insulation, sound insulation and absorption. Suspended ceiling plays an important role on the entire house decoration. Proper decoration to the house top surface, can not only beautify indoor environment, but also create a colorful interior artistic image. When choosing decoration materials and design of suspended ceiling, you should follow the principle of saving material, being solid, safe, beautiful and practical.

Q:What is the fire endurance of fireproof glass cotton?: The highest temperature of fireproofing glass wool can be above 200 degrees, so it can be used for a long time,it's difficult to judge the special usage time, but its usually about 3 months and 8 hours every day.

Q:what is steel fire door made of ?: 1. fire resistance steel door has steel made door frames, door leaf framework and door panels. if the door leaf is filled with nontoxic fire insulation material, added with fireproof hardware accessories, which consists of a door that is fire resistance.

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.
