Embodiment 1

[0078] A control method for reducing cost consumption per ton of alloy steel, the control method comprising the following steps:

[0079] 1) The smelting steel type Q345B belongs to the ordinary carbon steel series. The steel composition target value is: Si: 0.25%, Mn: 1.20%, of which Si recovery rate is 80%, Mn recovery rate is 90%, and carbon recovery rate is 90%;

[0080] According to the target value of steel component elements, the recovery rate of component elements and the content value of alloy component elements, the standard consumption of alloy per ton of steel is calculated according to the following formula, and the results are shown in Table 1;

[0081] Standard consumption of alloy per ton of steel = target value of steel component elements × 1000 ÷ alloy component element value ÷ component element recovery rate, where the component elements are silicon and manganese, and the alloys are high-manganese alloys, medium-manganese alloys, silicon-manganese alloys, and...

Abstract

The invention discloses a control method capable of reducing alloy ton steel cost consumption. The control method comprises a step 1) of calculating alloy ton steel standard consumption according to steel grade component element target values, component element recovery rate and alloy component element content value and according to a formula; a step 2) of designing an alloy adding model and calculating ton steel cost according to the alloy adding model; and a step 3) of calculating alloy adding variety and adding amount of smelting heat according to the alloy adding model with the minimum ton steel cost value based on results calculated through the step 2). After the control method is adopted, through the added alloy variety and weight, it can be guaranteed that alloy ton steel cost minimization is achieved on the premise that steel grade components are stable.

Description

technical field [0001] The invention belongs to the field of converter steelmaking, and in particular relates to a control method for reducing cost consumption per ton of alloy steel. Background technique [0002] With the continuous downturn of the steel market, cost reduction and efficiency increase have become an important part of enterprise management. Alloy cost is an important part of the steelmaking cost, and its consumption will directly affect the cost of the steelmaking process, and the alloy consumed by the converter is an important part of the alloy consumption. At the present stage, converter alloy blending is mainly considered from the perspective of steel composition, the consumption cost of alloy per ton of steel is diluted, and the proportion of different alloy blending is diluted, and the cost of alloy per ton of steel for blending has not been minimized. Therefore, it is necessary to adopt a control method to reduce the cost consumption of alloy steel per...
