- Q:Is there a worker in (Jigang refractory plant)?
- Exactly, you are not in the strict sense of the refractory plant contract worker, your contract is not signed and refractory plant, your wage system, and the worker in the factory is not the same, you can not follow the normal off-duty execution system
- Q:Is refractory material harmful to human body?
- Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
- Q:What are the applications of refractory busway?
- Fire-resisting busway can be applied to power transmission and distribution systems with rated voltage below 690V, rated current is 250-5000A and frequency is 50-60Hz. After years of testing and industrial electrical operation, its electrical resistance, fire resistance, metal structural property have reached the advanced level in China.
- Q:can slag tailings be used to be the base materials of refractory materials ?
- the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.
- Q:What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q:How many types of fire-resistant material?
- 1. Acid fire-resistant material refers to one with more than 93% SiO2. It is featured by resistance to the corrosion of acidic slag ad high temperature and easy to react with alkaline molten slag. 2. Alkaline refractory material generally refers to one with magnesium oxide or magnesium oxide and calcium oxide as the main component. It has high refractoriness and strong resistance to basic slag. 3. Silicate aluminum refractory material refers to one with SiO2, Al2O3 as the main component. According to the content of Al2O, it can be divided into three categories: half siliceous (15-30% Al2O3), clay (Al2O3 30 ~ 48%), high aluminum (more than 48% of Al2O3). 4. Fused cast refractory material refers to shaped refractory products made by high temperature melting and casting.
- Q:The development prospect of fire-resistant material
- Luweishi (Furnace guardian)--- the wings ofrefractory material (blast furnace for high pressure grouting and liningmaking)--- is the fortune of furnace repair companies. Nowadays the sales of refractorymaterial are very difficult, but furnace repairing is popular. It does not onlyearn money but also sell refractory material, and even establish long-term,stable and interdependent business relations provided the price is acceptable.Many forward-looking companies such as Beijing Rongda, Anshan Yongheng, WuahnKehong, Shandong Zhangqiu, Gongyi Huaxi, Hongda, Zibo Xinfu and Anyang Tecai,allowing for the steel mills which are rich and try to do things the easy way, turnrefractory plant into or include into building company, resulting in greatsuccess in the bid invitation among so many units. Junwei can provide quality and efficient blast furnace equipment for grouting and lininLuweishi--- Luweishi (Furnace guardian) and research, design and manufacture as required. QQ:76350883
- Q:What are the fire endurance requirements of class A fire resistant door ?
- The fire endurance of class A fire resistance door is 1.5H, but also depends on the product quality. The filling material of class A, B, C fire doors is the same, new fireproofing material-- perlite. The difference is their thickness. The general structure is: surface panel, fireproof?board framework (filled with perlite) fireproof?board panel. !
- Q:Who knows the fire endurance of B-level fireproof doors and windows?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. Fire endurance of fireproof windows: A-grade fireproof windows are not less than 1.5h and B-grade fireproof windows are not less than 1h. The door leaves of A-grade and B-grade fireproof windows should be steel materials, and their glass should be composite fireproof glass whose thickness is no less than 26mm. Monolithic fireproof glass window is not B-grade fireproof window, nor A-grade fireproof glass window. It si called non-insulated fireproof window.
