Product Description
DETAILED DESCRIPTION
Silicon Carbide (Black) is a high purity black silicon carbide refractory grain, which is made by fusing quartz and coke in high power electrical furnace. It characterizes the
high hardness, wear resistance ability, corrosion resistance ability and high-tempera-
ture strength. It is mainly used as deoxidizer in steelmaking process.
Silicon carbide deoxidizer is a new kind of strong compound deoxidizer can replace the traditional silica fume, it has more stable and dioxin effect, improved the quality of the steel, reduced the consumption and environmental pollution.
APPLICATION
1. The silicon carbide with low SIC content around 85% is always used in the metallurgy industry, as one deoxidize material.
2. With the SIC content is above 95%, because of its high refractory temperature, it is always used in the refractory industry.

- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- Mechanism analysis of silicon actionWhen silica fume is added to the carbon composite refractory, the phase changes and chemical changes are as follows:<1> Si (s) +C (s) =SiC (s) Delta G ~ =-522+1.50T (kJ)<2> Si (s) +MgO (s) =Si (g) +Mg (g) Delta G ~ =203.9-0.13T (kJ)<3> 2Si (s) +CO (g) =SiC (s) +SiO (g) Delta G ~ =-963.2+0.31T (kJ)<4> SiC (s) +CO (g) =SiO (g) +2C (s) Delta G ~ =81.47-0.15T (kJ)<5> SiO (g) +CO (g) =SiO2 (s) +C (s) Delta G ~ =-668.8+0.33T (kJ)From the above diagram and the reactions seen at high temperatures has joined the Si SiO and Mg volatiles, but <4> and <5> reaction have played a role in inhibiting carbon oxidation, and the condensation of SiO2 to a certain extent the role of protective film.The total reaction process is CO reduction to C, and there is a certain volume expansion, so that the pores are blocked and the density of bricks is increased. Therefore, the oxidation resistance of brick is improved.
- Q: Does the production of refractory belong to advanced technology？
- Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
- Q: Where is the distributing center of refractory materials in China?
- The infrastructure is perfect, service and refractory chemical industry professional market ancillary services, information, transportation, food, housing, and other one-stop perfection. The business service center, Yongan business city, Fukang company, Xu Bai Anlong logistics center and the market has been basically formed, the market in more than 200 dressing rooms at the end of September put into use, logistics center, warehouse industry nearly twenty thousand square meters can use for customers. The Fasthotel, the dormitory and the information center will be ready for delivery, and large transport teams will be built to provide accommodation, freight and other convenient services for the owners.
- Q: What antioxidant will be used in refractories?
- Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I can help you.
- Q: Who knows about the grade C fireproof door materials?
- Wood or steel materials are usually used in them. The new national standard fire doors: According to the enacted GB12955-2008, the fire endurance of grade C fire doors is 0.5 hours and that of grade A and B are 1.5 hours and 1.0 hours respectively.
- Q: How to deiron refractory?
- It cannot be done in conventional approaches, because you are referring to refractories. If using acid liquor soaking method to deiron, the material itself will be also damaged! If just for reducing the corrosion of materials, it will be OK to add a corrosion-resistant and fireproof protection layer.
- 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 kind of materials are needed to make refractory bricks?
- Fubang Decoration of Anhui province help you with the question: According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
