Quality Influencing Factor Analysis and Control Measures in Quality Carbon Steel and Alloy Structural Steel Produced with Converter

Aim for the lower eligible rate of macrostructure and forging in quality carbon steel and alloy structural steel produced with converter in Laigang, combine the examination and test of products and production practices, special test was designed to analyze the product quality defect such as forge crack, macrostructure crack and inclusion etc., analysis for quality defect in casting and products had been done by means of macrostructure analysis, electrolytic testing and energy spectrum. The technology improvement measures had been applied from smelt, continuous casting and products examination etc., and the quality of converter steel production was effective promoted.
