文档介绍：年产330万吨全连铸坯的转炉炼钢车间工艺设计
摘要
本设计的主要任务是设计一座年产330万吨方坯的转炉炼钢车间。本设计从基础的物料平衡和热平衡计算开始,主要包括以下几部分:转炉炉型设计、氧枪设计、转炉车间设计、连铸设备的选型及计算、以及炼钢操作制度和工艺制度,其中,转炉炼钢车间设计是本设计的重点与核心。
本设计设有转炉两座,转炉大小均为150t,平均吹氧时间为38min,纯吹氧时间为18min,转炉作业率为80%,转炉的原料主要有铁水、废钢以及其它一些辅助原料。连铸坯的收得率为98%,另外本车间炉外精炼主要采用了喂丝以及真空脱气手段。本车间的浇注方式为全连铸。车间的最终产品为方坯。
此次的设计任务更加巩固了我所学的专业知识,与此同时也更加了解了转炉炼钢车间的各道工艺流程,为以后的工作打下了良好的基础。

Abstact
The main task of this design is designing a plant wich perduce million tons of steel per year. It is e the foundation of the material and thermal calculation, mainly include the following parts: the bof model designing, oxygen lance designing, equipment selection and calculation of continuous caster ,besides,also including operating and process system of steelmaking ,the core of the design is plant layouting
This design has two 150t converter for steelmaking, the average time of oxygen applying is 38min ,pure oxygen applying time is 18min, the efficient of the bof is 80% , scrap metal and other auxiliary materials. The rate of casting billet is 98%, in addition , refining mainly adopts wire feeding and vacuum deairing, The final product is billet.
The design more strengthened my major knowledge, at the same time also understand more about the converter steelmaking of each process , laiding a good foundation for the work of future.
Keywords: top and bined blown converter steelmaking refining casting continuous casting
