钒产品的生产过程是承钢的特色项目,为了实现提钒生产的自动过程,由炼钢及自动化决定进行提钒系统设计,即实现提钒自动化。建立转炉提钒静态模型的目的。通过现场数据,协调各工序之间的联系,根据冶金原理,系统给出冷料预报和供氧操作提示和终点预报(控制),可以控制原料使用的准确性,及半钢成分的标准性,在有条件的情况下可实现氧枪自动控制,缩短周期,稳定指标。建立转炉提钒静态模型的目标是控制提钒的转化温度,提供合理的冷料配比和氧耗,在提钒过程中尽量减少碳的烧损,同时降低半钢残钒、提高钒渣品位,从而达到稳定提钒技术指标、提高提钒技术水平。
The production process of vanadium products is a featured project of Chengde Steel. In order to realize the automatic process of extracting vanadium, the design of vanadium extraction system is decided by steel making and automation, that is, the automation of extracting vanadium is realized. The purpose of establishing static model of vanadium converter was established. According to the metallurgical principle, the system gives the warning and end-point forecast (control) of cold material forecast and oxygen supply operation, and can control the accuracy of raw material usage and the standard of semi-steel components, In the case of conditions can be achieved automatic control of oxygen lances, shorten the cycle, stability indicators. The goal of establishing a static model of converter vanadium extraction is to control the conversion temperature of vanadium extraction and provide a reasonable ratio of cold materials and oxygen consumption, minimize the carbon burning in the process of vanadium extraction, reduce the residual vanadium in semi-steel and raise the vanadium slag grade , So as to achieve a stable technical index of vanadium extraction and improve the technical level of vanadium extraction.
