摘要

由于市场对钢材的大量需求，现代化的炼钢设备都在向着大型化的方向发展，本设计主要是模拟建立一个现代化年产200万吨的中型炼钢企业，以满足市场对钢材的需求，促进经济的稳定发展。

设计内容主要包括：转炉炉型设计、氧枪喷头设计、各种附属设备的确定等。 通过本设计从而获得有利于冶炼的参数，对现场生产起到一定的指导作用，并为现场生产提供理论依据。

关键词：炼钢；炉型设计

ABSTRACT

Because of the high demand for steel market, modern steel-making

II

equipment toward the direction of bigness in development, this design is mainly simulation in liupanshui city to build a modern yearly produces 200 tons of medium-sized steelmaking enterprise, to meet the market demand for steel, and promote steady economic development.

Design content mainly includes: converter type design, oxygen lance nozzle design, various attached device sure, etc.

Through this design so as to achieve the parameters for smelting, to the field production play a guiding role, and provide theoretical basis for the field production.

Keywords: steelmaking; Furnace type design
