1. Blowing argon; Blowing argon starts from tapping until the ladle reaches the LF waiting position. 2. Ladle to LF waiting position; After the ladle reaches the LF waiting position, the argon blowing tube is turned on, and ensured the argon blowing amount. 3. Refining slag ; The purpose of making refining slag : desulfurization, absorption of inclusions in molten steel, prevention of secondary oxidation, etc. 4. Ladle sampling; After heating and treating the slag (the slag is basically whitened), measure the temperature, take the first sample, add the alloy, homogenize and adjust the temperature. 5. Feed the Ca-Si wire; The best feeding time is that the molten steel is in good composition, good fluidity and not breaking the slag layer. 6. Stop blowing argon, ladle hanging to continuous casting. After stirring for 5 minutes with argon, add covering agent. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making r...

Pre-melted refining slag is widely used as deoxidizer. It is mainly used in steel deoxidation and other impurities, with rapid slagging and other advantages, effectively reduce the inclusion of steel. It has features as follows: 1. Smelting smoothly, reduce the water splash, which can improve the liquid steel yield of about 1%. 2. Less time of smelting cycle. refining slag , high efficiency rate, can achieve smelting time is shortened. 3. To create a good dephosphorization conditions in the furnace. To achieve the purpose of pre-dephosphorization, improve the rate of 3% to 5% dephosphorization. 4. Accelerate the lime dissolved. There is no need to use fluorite to help melt, to achieve fluorine-free steel; furnace erosion to reduce the reduction of environmental pollution. 5. To be melted quickly. As a result of pre-melting, has formed a low melting point of the mixture. It will form into liquid once added into furnace, to achieve the purpose of smelting ...
