Silicon calcium cored wire

Calcium silicon cored wire is an important product required for industrial steelmaking. After understanding calcium silicon cored wire products, it is necessary to understand the feeding process knowledge of calcium silicon cored wire. The following is a detailed introduction to the feeding process knowledge of calcium silicon cored wire. The calcium-silicon core material line method has simple equipment, convenient operation, small footprint, small investment, safety and reliability, low processing cost, no smoke, small temperature drop (5 ~ 7 ℃), large molten steel absorption, no need for refractory materials and load The gas consumption is small and the alloy absorption rate is high. It is an effective and simple out-of-furnace refining method for deoxidation, desulfurization and alloy fine-tuning and control of the form of inclusions. Compared with the bulk material input method, the feeding method of silicon calcium cored wire has the characteristics of high yield, high refining hit rate, and suitable for fine-tuning of alloying elements in steel. The advantages of the feed line method compared with the powder coating method:
1. The stirring of molten steel caused by this is much smaller than that of powder spraying, which reduces splashing and suction of molten steel.
2. The temperature loss is reduced by 3~6 times, about 5~7℃/min.
3. Can accurately adjust the chemical composition of molten steel.
4. According to the content of aluminum and sulfur, adding an appropriate amount of Ca-Si can completely improve the morphology of the inclusions.
5. Low investment cost and operating cost.
