The invention relates to the technical field of ferrous metallurgy casting, in particular to a vertical semi-continuous production device for large round billets with the diameter of 1000mm-2000mm and the length of 5 m-15 m and a production method of the vertical semi-continuous production device. A pipeline type induction heating steel ladle base is an auxiliary system of a pouring system; the pouring system, a cooling system and a casting billet lifting system are sequentially arranged from top to bottom; a split type electromagnetic stirring system and a casting billet temperature control system are arranged around a round billet as a casting billet quality control system; and a billet discharging system, a casting billet conveying sliding way and a casting billet slow cooling system are sequentially arranged on one side of the production device. The technical scheme solves the problems that in the prior art, the productivity is low; the energy consumption is high; land occupation and investment are large; the method is not suitable for customized production; the core quality is difficult to control, and macrosegregation, looseness, shrinkage and the like are likely o occur; and the quality control is difficult to realize.
Description
technical field [0001] The vertical semi-continuous production device of φ1000mm-φ2000mm large round billet and the production process thereof of the present invention relate to the technical field of iron and steel metallurgy and casting, in particular to a vertical semi-continuous production device for large round billets with a diameter ranging from φ1000mm to φ2000mm and a length ranging from 5m to 15m. Continuous manufacturing apparatus and production method thereof. Background technique [0002] With the rapid development of nuclear power, wind power, hydropower and steel industries and the development trend of large-scale equipment, the market demand for high-quality large-scale castings is increasing. Castings are a type of product with more market demand, and are widely used in large-scale backup rollers, fan shafts, nuclear power and hydropower generator set rotors, ship main shafts, bearings and other fields. At the same time, the downstream industry is also urge...
