Detection system for continuous detection of molten steel temperature and composition for converter steelmaking

Abstract

The invention discloses a detection system for the continuous detection of the molten steel temperature and the composition for converter steelmaking, and relates to the technical field of steelmakingdetection equipment. By arranging a seating brick and a probe conveying pipe on the side wall of a converter, probes of various types are arranged in different detection through holes in the probe conveying pipe respectively, the molten steel temperature, the molten steel oxygen activity, and the low carbon and phosphorus content in the molten steel in the converter can be detected in real time,and an operator conveniently takes the corresponding operational means to reach the smelting end point in an optimized manner so as to improve various economic and technical indexes in steelmaking.

Description

technical field [0001] The invention relates to the technical field of steelmaking detection equipment, in particular to a detection system for continuous detection of molten steel temperature and composition in converter steelmaking. Background technique [0002] At present, the main steelmaking equipment in China is the oxygen top-blown converter. During the blowing process of the converter, the temperature and composition of the molten steel are detected. Very few converters use the sub-lance system. In the middle of the blowing, the sub-lance probe is inserted into the molten steel from the converter mouth Take steel samples, measure molten steel temperature and oxygen, and determine carbon by crystallization. At the end of blowing, use the sub-lance probe to take samples; detect the temperature of molten steel and the oxygen activity of molten steel and calculate the corresponding carbon content. In recent years, a very small number of converters have installed throwing...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above that the current detection system and state cannot provide steelmaking operators with real-time and continuous molten steel temperature and the requirements of important components

[0004] Because the operator cannot accurately know the current molten steel temperature and composition, he often adopts some safe operation methods for the operator, such as high tapping temperature, low carbon, large slag content, etc., which will lead to failure of the converter. The decline of various economic and technical indicators will also lead to quality and production accidents
