Si55 Ba10 Ca10 Ductile Iron Inoculation Calcium Silicon Barium Ferror Alloys
Silicon strontium calcium is a composite deoxidizer. In addition to good deoxidation effect in steel smelting, it also has a certain role in purifying molten steel. Both silicon and germanium in the silicon germanium calcium react with oxygen to form oxide impurities, which float on the surface of the molten steel for easy removal. Calcium and barium also have certain removal effects on harmful impurities such as sulfur and phosphorus in the molten steel, which can reduce the components of harmful impurities in the molten steel.
The main components of silicon germanium calcium are silicon, germanium and calcium, of which Ca30.16% is deoxidized by silicon germanium. Because the vapor pressure of Ca is very high at the steelmaking temperature, the reaction is fierce, and some deoxygenated products are gases. CO, steel liquid agitation is relatively strong, which is conducive to rapid melting of the alloy and uniform composition. The silicon germanium calcium added to the steel is present in the steel in the form of calcium oxide, calcium sulfide and calcium aluminate. Since the AI2O3 in the steel and the deoxidation product of the calcium strontium form a composite calcium salt inclusion, the steel is pure. The aluminum inclusions are reduced. Effectively reduce the vapor pressure of calcium in the steelmaking temperature range and increase the solubility of calcium in the molten steel. Compared with the silicon-calcium alloy, the silicon-germanium-calcium alloy is added to the molten steel as a calcium source, and even the amount of calcium added is When the amount of calcium alloy added is half, the calcium content in the molten steel is about twice that of the silicon-calcium alloy, and the calcium is also significantly increased in the molten steel, which fully shows that the strontium effectively protects the calcium in the molten steel and reduces the calcium. Oxidation, so as to achieve the purpose of treatment of molten steel.
Performance and use:
1. Silicon strontium calcium alloy is a high-efficiency new composite alloy in lanthanide alloy. It is a deoxidizer, desulfurizer and dephosphorization of steelmaking; it is an inoculant and a modifier in casting.
2. The effective reduction of the vapor pressure of calcium in the steelmaking temperature range increases the solubility of calcium in the molten steel. Compared with the silicon-calcium alloy, the silicon-germanium-calcium alloy is used as a calcium source to be added to the molten steel. When the amount of calcium added is half of that of the silicon-calcium alloy, the calcium content in the molten steel is about twice that of the silicon-calcium alloy. Calcium is also significantly increased in molten steel. It fully shows that strontium effectively protects calcium in molten steel and reduces the oxidation of calcium, thus achieving the purpose of treating calcium in molten steel.
