Abstract：In current steelmaking process technology, predominantly hot metal pretreatment using blast furnace hot metal as the raw material, the molten iron is charged into the oxygen converter through molten iron and other equipment, and then the top and bottom re-blow, and then the scrap steel is added. oxygen. This design adopts the top-bottom re-blowing process to design an oxygen transcription steelmaking workshop, and it is estimated that the annual production volume will be about 2 million good steels. The workshop adopts the technology of three blows and the reasonable arrangement of the labor capacity of the steelmaking workshop. Three oxygen converter RH refining furnaces were designed. Oxygen converter model design, oxygen grab design, overall distribution design of the workshop, design of oxygen purification system; hot metal supply system, scrap supply system, bulk material supply system, off-road refinement system, gating system and slag treatment system. The rational design of the oxygen plant layout ensures that the oxygen converter plant is one of the keys to the reduction. The workshop is designed with three 100t oxygen converters. The smelting cycle of the oxygen converter is 42 minutes and the oxygen blowing time is 22 minutes. Oxygen converter steelmaking is a process technology for obtaining ideal steel by removing impurities and adding various required elements. This technology provides the steel needed for production equipment in our daily life. The thickness of the hearth of the oxygen converter workshop is 980mm and the thickness of the furnace body is 910mm.

With reference to the current development trend of converter steelmaking technology at home and abroad, combined with the design of the task book workshop, RH furnace refining equipment has been selected for full continuous casting production. The technological process of steelmaking technology: blast furnace hot metal—mixed iron vehicle—oxygen converter blowing—external refining—all continuous casting—good billet.

Based on the material balance and heat balance calculation of the converter, this design has designed and selected the parameters of the main equipment of the steelmaking plant, including the furnace body design of the oxygen converter, the oxygen lance design, the RH refining furnace, and the Caster design and other equipment. At the same time, it completed the main equipment of the workshop, the design of the steelmaking process, the layout of the main delivery room of the workshop and the layout of the equipment. At the same time, the furnace profile of the oxygen converter, the furnace profile of the RH refining furnace and the floor plan of the workshop were compiled.
