Title:
PRODUCTION OF STEEL MATERIAL
Document Type and Number:
Japanese Patent JP3766503
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To determine the steel production component and production conditions of steel plate to easily deal with the request of ordering person without requiring any skilled quality designer.
SOLUTION: As a method for determining the production conditions, the quality request of order is developed to 'request characteristic value required for a steel material'. Next, it is developed to 'slab characteristic value' correspondent for each request characteristic value and synthesized for each slab characteristic value item by high-order summarization. Next, it is developed to 'production conditions' correspondent for each slab characteristic value and synthesized for each production condition item by high-order summarization and a production instruction is determined. As a method for determining the steel production component, a component element value is found for each 'request characteristic value'. Next, a CEQ expression is determined from the component value. Afterwards, a steel production CEQ is determined from an allowable strength range and drawing temperature range while using the CEQ expression and based on the steel production CEQ, the steel production component is determined from component process ability.
