To be prepared by the raw materials through high-temperature baking

　　To be prepared by the raw materials through high-temperature baking, the essence of the furnace to use high-quality lime, can not be mixed with impurities with white ash. Ingredients in the pig iron content is higher than 30%, in the exercise to try to improve the full melting of carbon, to ensure that the discharge of impurities and bubbles. The temperature of 6inch A403 Wp316 Schedule 10s Bw Stainless Steel Tee is higher than 1650 degrees Celsius. After the de-slag to do deoxidation. After the smelting of the aluminum particles to participate in deoxidation to make the slag white. Mix in the process with nitrogen. When the composition adjustment is appropriate for sampling analysis, until the compliance with the specifications of casting. In the ingot stripping the future, in a half hour to send casting. In the insulation pit placed 20-60 hours, when the temperature at 650-750 degrees Celsius into the high temperature furnace for heating. And then casting, annealing. In order to prevent deformation, there is a certain demand for the tempering temperature, to ensure that the tempering temperature can not be too high, back to the back of the finished product, in order to prevent deformation, Fire evenly. And then sampling analysis.
