Silicon carbide
silicon carbide (SiC) with quartz sand, petroleum coke (or coal), wood chips as raw material in electric arc furnace smelting made. In nature there are silicon carbide rare mineral, Moissanite. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. Silicon carbide is quartz sand, petroleum coke (or coal), wood chips (need to increase the production of green silicon carbide salt) and other raw materials at high temperature resistance furnace smelting. At present, China's industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, are hexagonal crystals, accounting for 3.20 to 3.25, micro hardness of 2840 ~ 3320kg / mm2.
Uses
(A) as an abrasive, can be used for abrasive, such as wheel, Whetstone, grinding, sand tile and so on.
(2) as a metallurgical deoxidizer and high temperature materials.
Silicon carbide has four major application areas, namely
functional ceramics, advanced refractories, abrasives and metallurgical materials. Silicon carbide has been able to present a large supply of coarse material, can not be considered high-tech products, and high-tech applications nanoscale silicon carbide powder is impossible to form a short period of economies of scale.

- Q: What advantage and disadvantages it has compared to common fire insulation materials
- Generally speaking, high fire resistance, non combustible Various standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. I hope my answer can slove your problem
- Q: What is the role of adding chromium oxide green in unshaped refractory materials
- Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
- Q: How much modulus is used as refractories material of sodium silicate.
- Storage and use are very convenient, especially for mechanized and the evenly refractory material and the sodium silicatemodulus is generally...2. transportation. The appearance of product is pure white. Instant powdered sodium silicate, also known as instant sodium metasilicate.4 to 3, in powder form, automation. in the range of 3, hydrated sodium silicate
- Q: How long does it take for refractory cement to solidify?
- 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.
- Q: What characteristics do A grade external wall fireproofing material have?
- 1. Save space and reduce costs; 2. Fireproofing, green and environmental protection; 3. Waterproofing; 4. Sound insulation; 5. Thermal insulation; 6. Install easily and shorten the construction period; 7. High safety performance.
- Q: which kind of refractory is used in golden smelting furnace? How about his using temperature
- generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
- Q: As for fireproofing material rock wool and glass wool, which one is better?
- As for fireproofing effect, the effect of rock wool is certainly better than glass wool , the highest temperature of rock wool is 1100 ℃, but the temperature of glass wool is only 600 ℃. In addition, if it's used in the external walls, then,unit weight of the glass wool is limited,and high unit weight can only be 60-90, but unit weight of rock wool can reach over 140, now external wall can't use glass wool, and only rock wool is A class fireproofing material. glass wool has lower thermal conductivity, rock wool has longer fiber length,as for the price, tons price of glass wool is more expensive than rock wool, but if it's acculated by square, square price of glass wool is cheaper than rock wool.
- 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: Why does refractory need to add coarse firstly and then add fine aggregate?
- Binding agent can wrap particles and improve binding effect.
- Q: What kind of refractory material should be used for common boiler?
- Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red?brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
