Abstract

The invention provides a residual element content regulation and control method for full scrap steel electric arc furnace smelting. The method comprises the following steps: obtaining the residual element content of a waste steel raw material; the waste steel raw materials are classified based on the residual element content and the preset element removal difficulty level; based on a preset constraint function, the adding amount of the various waste steel raw materials is calculated, and constraint parameters of the constraint function comprise the residual element content of the various waste steel raw materials and a preset residual element content upper limit threshold value; and smelting parameters are calculated based on the addition amount of various waste steel raw materials. According to the method, the waste steel raw materials can be classified according to the content of the residual elements, the adding amount of each type of waste steel raw materials is calculated based on the preset constraint function according to the content of the residual elements of the waste steel raw materials and the preset threshold value of the content of the residual elements, the smelting parameters are obtained, and the component requirement of smelting for the residual elements is met; the problem of regulating and controlling the content of the residual elements in the full-scrap steel electric arc furnace smelting is solved.

Description

Technical field [0001] The present invention relates to the field of arc furnace steelmaking techniques, and more particularly to a residual element content regulation method for a full scrap steel arc furnace. Background technique [0002] Electrical arc furnace steelmaking is one of the main steelmaking methods of the world. It has the characteristics of short-range process, short energy-saving and environmental protection, and is an important driving force for green manufacturing in the steel industry. Electrical arc furnace steelmaking not only produces ordinary rod wires, but also high quality special steel smelting main processes. In recent years, with the development of the economy, the demand for high quality special steel has increased, so the requirements for the quality of electric furnace steel products are also increasingly strict. The scrap steel has been increasingly increasingly increasing by multiple recycling, Cu, and AS residual elements, and residual elements ...
