Stainless steel intelligent smelting system

Abstract

The invention discloses a stainless steel intelligent smelting system, which comprises a stainless steel argon-oxygen decarburization (AOD) smelting furnace and an intelligent smelting system connected with the stainless steel AOD smelting furnace, wherein the intelligent smelting system consists of a gas control system, an AOD operating workstation and an AOD automation system; the AOD operating workstation consists of a human machine interface (HMI) system, a personal computer (PC) server and a programmable logic controller (PLC) module; and the AOD automation system consists of a database and an intelligent smelting model. The stainless steel intelligent smelting system is provided with the human machine interface for a user, and operation is convenient and intuitive; and the database calculates and displays chemical compositions in molten steel and the temperature of the molten steel in the furnace by a picture in real time according to the consumption of the gas. The stainless steel intelligent smelting system is suitable for small, medium as well as large steel mills and solves the problem of the complicated steelmaking process for the user because the operation is convenient; and because of reasonable price, the smelting cost can be greatly reduced for the user, and the stainless steel intelligent smelting system is easy to promote.

Description

technical field [0001] The invention relates to an intelligent stainless steel smelting system, which belongs to the intelligent stainless steel smelting system in the metallurgical industry, improves the quality of stainless steel, increases the yield of finished products, reduces production costs, and is suitable for the rapid development of stainless steel. Background technique [0002] China began to produce stainless steel in the early 1950s. At that time, 3t electric arc furnace was used for smelting. There was no refining equipment outside the furnace and continuous casting. The annual output was only several hundred tons to several thousand tons, and the quality, variety and cost could not meet the requirements. [0003] Since the 1980s, units such as Taiyuan Iron and Steel Company and the General Iron and Steel Research Institute have taken the lead in developing AOD refining technology in China. Subsequently, various special steel mills successively installed 18-40...

Problems solved by technology

[0010] At present, 95% of domestic stainless steel smelting is realized in AOD furnaces. However, in recent years, AOD furnaces designed and manufactured in China are biased towards manual operation, requiring many instruments and buttons, and a lot of manual work to estimate the relevant parameters in the smelting process. Chemical composition and estimated temperature of molten steel, which brings cumbersome and inaccurate smelting process, resulting in increased cost of smelting and quality of steel
