TCO Endpoint Control System for Converter Steelmaking

Abstract

In the course of production technology of converter steelmaking, accurate and fast measurement such technical indicators as temperature, content of carbon and content of oxygen of molten steel in the converter, especially the technical indicator of the molten steel of endpoint, it is significant to guarantee the quality of steel products and reducing energy consumption. The structure of equipments, the technological principle of TCO and its application in steelmaking are described and specially the results of TCO application in No. 4 converter in Handan Iron and Steel Co. Ltd are introduced. The converter TCO endpoint control system reaches the equal effect that subsidiary gun measurement controllers, improving two blowing endpoint hit rate, shorting smelt period, and reducing various consumption, improving steel mass effectively. A bright prospect for popularization of this technology in China is pointed out.
