广东中南钢铁股份有限公司炼钢厂开发了一套基于副枪的转炉炼钢控制模型软件，该软件包含静态模型、动态模型、自动吹炼控制。通过静态模型完成停吹温度计算、熔剂计算、静态氧量与冷却剂计算，在副枪TSC探头测量后激活动态模型，通过动态模型实时计算钢液碳含量及温度，并引入了自学习方法提升静态模型与动态模型的准确性。通过将静态模型与动态模型计算结果发送至一级机实现了一键自动吹炼功能。炼钢模型增加了停吹磷预测、底吹跟踪、实用报表等功能，为岗位操作提供了决策依据。通过炼钢模型的应用，自动炼钢率达到90%，停吹钢液碳含量及温度双命中率达到90.9%，补吹率由15.91%降低至4.89%，降低了冶炼成本，取得了较好的效果。

Guangdong Zhongnan Iron & Steel Co.,Ltd.has developed a computer-aided steelmaking control model for its converter,based on sub-lance technology.The model integrates static and dynamic sub-models with automatic blowing control.The static sub-model calculates target parameters such as blow-off temperature,flux addition,static oxygen volume,and coolant requirement.After measurement with the TSC probe,the dynamic sub-model is activated to provide real-time predictions of molten steel carbon content and temperature.Both sub-models employ a self-learning algorithm for rapid parameter optimization.By transmitting the calculation results from both models to the primary control system,one-click automatic blowing has been realized.The enhanced steelmaking model also incorporates new functions,including end-point phosphorus prediction,bottom-blowing tracking,and operational reporting,offering robust decision-making support for on-site production.With the implementation of this software,the computer-assisted steelmaking rate has reached 90%,the simultaneous hit rate for carbon and temperature at blow-down has achieved 90.9%,and the reblowing rate has been significantly reduced from 15.91%to 4.89%.These improvements have effectively lowered smelting costs and delivered substantial operational benefits.
