description The invention provides a method for establishing influence of harmful elements on blast furnace smelting and a regulation and control standard. The method comprises the following steps: carrying out harmful element load analysis on blast furnace raw fuel, and further calculating to obtain the enrichment amount and enrichment multiple of harmful elements such as potassium, sodium and zinc in a blast furnace; based on the enrichment amount, preparing crude fuel with harmful elements in a cyclic enrichment state under different load levels , and obtaining a quantitative relation model between the load levels of the harmful elements and the metallurgical performance change of the crude fuel; and establishing a quantitative relation model between crude fuel metallurgical performance and blast furnace smelting technical indexes by analyzing production data, obtaining an influence rule of harmful elements on blast furnace smelting technical economic indexes by combining the model, and formulating an optimal harmful
