From the above form, we can get the result that using Si-C alloy can help to improve the qualification rate.

Mechanical Property Comparison:

From the above forms, we can get the conclusion that, the mechanical property of the test steel, which has used SI-C, can be much more stable.

After using SI-C alloy, the average tapping temperature has been improved 9℃, and the average temperature drop has also increased 6℃.

We can see from the data that, using Si-C alloy can helps to save cost about 4.787RMB.

Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?: In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal?mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Binding agent can wrap particles and improve binding effect.

Q: What are the fire resistance ratings of the glass partition?: When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.

Q: What are the fire resistances of grc partition panels?: fire resistance of partition panel≥3.5h, it has an excellent fireproof performance and can be applied to fire-proof bulkhead.

Q: What are the raw materials of refractory?: Refractory is mainly resistant to high temperature and fire. Sic refractories are widely used in refractory. I hope my answer will be helpful to you.

Q: What is the interior fireproof thermal insulation material?: The methods of thermal insulation wall have three kinds of materials. First: gypsum board or cement board are stuck outside the polyphenyl board; second: lightweight brick build; third: infill polyphenyl board, lightweight brick is built outside. The first two has almost the same price. The latter is slightly expensive. 60 yuan / square meter is not very expensive!

Q: Which brand of refractory fiber hard thermal insulation board is better?: One colleague said Huayou refractory fiber hard thermal insulation board is good. The size (mm): 600*400*60. refractory temperature: 1770 ~ 2000 ℃ (℃), and the price is 2850 yuan a ton.

Q: What are the components of refractory clay?: It is different from non-cement castable refractories, which does not rely on the addition of cement for combination, instead it uses chemical binder. It is refractory castable (also known as chemical bonding castable). Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. Since the use of superfine powder or sol as binder, it has low impurity content, and therefore the refractoriness and slag erosion resistance of the castable will not be reduced. Besides, the self combination in use can help to improve high-temperature structural strength. Non-cement castable refractory is made up of refractory aggregate and powder, superfine powder of oxide or sol, trace amount of dispergator (or anti-coagulant) and proper slow acting hardener. Non-cement castable is mainly coagulated and combinated by ultrafine powder of oxide or sol, therefore, it has certain requirements for ultrafine and sol. Ultrafine powder used refers to less than 1 / zm particles. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. SiO micro powder is often adopted, which is the dust recycled during the smelting of metallic silicon, ferro-silicon alloy, the generation process is as follows: This recycled SiO2 powder has an average particle diameter of 0.5 pM, and it is spherical with large surface area. It is amorphous substance with high activity, so it has good bonding strength. The sol used are mainly alumina oxide and silica sol. Silica sol is made by ion exchange of sodium silicate after Na ions are removed. It can also be made after hydrolysis of ethyl silicate. There are several ways of preparing alumina sol, the easiest method is to prepare by the reaction of metallic aluminum or alchlor with hydrochloric acid.

Q: what's the detailed address of fireproof and thermal inuslation matertial market?: Detailed address of fire insulation materials market is as follows: A: Guangzhou Huatai building materials co., LTD. Address: Guangzhou Tianhe Chepo Road no. 10 B: Address of Donglong building materials market: Guangzhou Tianhe Taian North Road no. 7 C: Address of Huiya building materials trade market : Guangzhou Tianhe Sports West Road No. 109

Q: I wanna ask about the thermal insulation material fire resistant level?: The inorganic glass wool, rock wool and foam glass. Organic: The best is the phenolic foam, phenolic foam composite cement layer is level A.
