There are many advantages of melting molten iron in cupola furnaces or electric furnaces, and adding the pretreatment agent SiC. Silicon carbide is divided into abrasive grade and metallurgical grade, the former is high purity and expensive, and the latter is inexpensive. The silicon carbide added to the furnace is converted into carbon and silicon of cast iron, one is to increase the carbon equivalent; Second, it strengthens the reducibility of molten iron and greatly reduces the adverse effect of corroded charge. The addition of silicon carbide can prevent carbide precipitation, increase the amount of ferrite, make the cast iron structure dense, significantly improve the processing performance and make the cutting surface smooth. Increase the number of graphite balls per unit area of ductile iron to improve the nodularization rate. It also has a good effect on reducing non-metallic inclusions and slag, eliminating shrinkage porosity and eliminating subcutaneous porosity.
Silicon carbide is used as a high-temperature indirect heating material due to its high temperature resistance, high strength, good thermal conductivity, and impact resistance, such as pot distillation furnaces, distillation furnace trays, aluminum electrolytic cells, copper melting furnace linings, and arc furnaces for zinc powder furnaces. Profile plate, thermocouple protection tube, etc.
| Product performance 1. High chemical stability, low thermal expansion coefficient, high thermal conductivity, and resistance temperature characteristics are opposite to those of metals; 2. High hardness, with Mohs hardness reaching 9.5, it is the first wear-resistant additive for materials; 3. Wear-resistant, high temperature resistant, corrosion resistant, acid and alkali solvent resistant, widely used in coatings and paints to increase wear resistance; 4. It has good toughness, excellent grinding performance, and excellent electrical dissipation and thermal conductivity. |
