Steel refining such as stainless steel under normal pressure does not involve vacuum, but can achieve a wide range of refining effects such as decarburization, deoxidation, desulfurization, removal of inclusions, control of components and temperature. The main refining methods under normal pressure are: 1. Synthetic slag washing is an early development method for refining outside the furnace. The synthetic slag is placed in the ladle, and the kinetic energy of the molten steel is poured to form an emulsion of steel and slag to increase the contact surface of the steel-slag, thereby accelerating the refining reaction speed and achieving the effects of desulfurization and deoxidation. 2. The ladle is argon agitated. In order to improve the deoxidation efficiency, the argon gas is blown from the bottom of the ladle, and vigorous stirring is performed to float the trapped inclusions to achieve the purpose of uniform temperature and composition of the molten steel. 3. Add slag to the ladle with synthetic slag. In order to prevent reoxidation and absorption of molten steel during argon blowing, the first two methods are used in combination. When argon blowing is carried out, the slag washing is carried out by sinking into the hood, and the slag washing is called SAB method; when the slag is added from the ladle cover, the slag washing is called CBA method. Both methods have the same refining action, which reduces the total oxygen content of medium and low carbon steels, including low alloy steels. At the same time, the alloy and deoxidizer control components are added, and the converter can be combined with the converter to produce low-nitrogen steel. 4, LF method. Arc heating, argon agitation, increase temperature, promote metallurgical reaction, reduce oxygen content, and substantially remove inclusions. 5, dusting refining method is also known as ladle jet metallurgy. These include the TN process, the CBA/TN process, and other methods of adding alloying elements and refining materials. 6, stainless steel refining method. The AOD method refines stainless steel under normal pressure. On this basis, the CIU method has been developed. The two furnace types and the smelting process are basically similar. The difference is that the CIU method uses steam instead of argon gas.
