Introduction to Steelmaking
There are countless ways to make steel in today's society according to different technologies. Steelmaking refers to controlling the carbon content (generally less than 2%), eliminating harmful elements such as P, S, O, N, and retaining or increasing Si, Mn, Ni, Cr Equal beneficial elements and adjust the ratio between elements for optimal performance. The pig iron for steelmaking is put into the steelmaking furnace and smelted according to a certain process, that is, steel is obtained. Common steelmaking methods can be roughly divided into converter steelmaking, open hearth steelmaking and electric furnace steelmaking according to different steelmaking furnaces. Steel products include ingots, continuous casting billets and direct casting into various steel castings. Generally speaking, steel generally refers to steel that is rolled into various types of steel. There are many steel-making methods and more steel-making equipment, but due to the particularity of steel-making, all steel-making equipment is inseparable from the rotary joint. Rotary joints have also developed rapidly because of the steelmaking industry, and there are already categories of steel mill rotary joints that are specially used in the steelmaking industry.
