What crucible can be used to make steel? At least 1500 degrees resistant
BOF is carried out in the converter. The converter is shaped like a pear, wall brick, oven side holes (outlet), compressed air from these holes blowing furnace, also called side-blown converter. Initially, the converter at the level of 1300 degrees Celsius, inward injected liquid raw lime and iron. Adding a certain amount of air, and then make it stand upright and rotate the converter.
But be sure to make sure the graphite crucible is well lined and the furnace lining must be secured as concentric as possible, thus avoiding the flame deflection in the flame furnace and impacting the crucible to ensure that the induction furnace is in normal working condition
A graphite crucible is a very important purpose is to iron and steel. The oxidant using this process is oxygen. The air is blown into the molten iron, the impurity of silicon and manganese oxide. The release of large amounts of heat in the oxidation process (including 1% silicon iron can make the temperature rise of 200 Celsius), can make the furnace reach a high enough temperature. So the converter does not need the additional use of fuel.
At this time, the surface of the liquid pig iron reacted violently, causing iron, silicon, manganese oxide (FeO, SiO2, MnO) to produce slag, using the convection action of molten steel and slag to make the reaction spread throughout the crucible furnace
