- Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
- Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
- Q: What are the specifications of fire resistant bag?
- Currently there are four specifications: C10, C40, B40 and B50 suitable for steel ladle of less than 60 tons. I hope it can help you.
- Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?
- 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Many enterprises need refractory materials. You can go to Mianyang large private enterprises to askSupermarkets, stations, hotels are required
- Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
- Chrome drainage sand can be used for coupling process there are many manufacturers do it, this is mainly a lot of chrome, chrome iron ore mainly refers to the drainage sand, adding ladle material amount regulator performance guide. Drainage sand as filling material of ladle bottom nozzle, one hand can be sintered at low temperature, to avoid joining the molten steel drainage sand floating accident, on the other hand, in the high temperature and long time refining steel surface can not meet the state of sintering is too thick, otherwise it will affect the automatic pouring rate, Hua Heng worth a try I'm not favored, my sky is the wind or rain rainbow you hate yourself in the manipulation of really useless emotional heart to still ache for breaking up before the sorry shuttle time in the moving picture of the clock in the opposite direction when the initial time begins to move back to love you
- Q: What's the refractoriness and how to measure the refractoriness?
- Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.
- Q: Which one is better, fire-resistant wood or steel?
- From the aspect of low-carbon and environment protection, the steel and timber structures are both OK, they are both renewable resources, the steel can be recycled and melt down again and wood can continue to be planted. Fireproof board Fireproof board is a refractory material used for surface decoration. It is widely used in interior decoration, furniture, kitchen cabinets, laboratory tables, walls, and other fields.
- Q: What kinds of refractory materials that can resist 3,000 Celsius degree?
- I think that graphite is the only one.
- Q: What is the the best ratio of mortar in refractory cement?
- Specifical proportions are as following: 42.5R cement is 425 rapid hardening cement. Using the 425 cement to compound the mortar. The reducion of cement will naturally impact the workability of the mortar. The mix design standard of the mortar specifies the minimum amount of cement is not less than 200kg / m3. If it is composite mortar, and the strength and workability can be ensured, it is Ok to use 425 to compound. You can look for instructions of mixing proportion of mortar online as a reference.
- Q: what materials can make external wall fireproofing paint have the fireproofing effect
- Fire retardant coating material is composed of the base material (film forming substance), pigments, ordinary paint additives, fire retardant agent and dispersion medium. Except fire retardant agent, the function of other coating component is same to the commom coating, but the performance and the dosage have special requirements.
