Abstract

The invention belongs to the technical field of metallurgy, and particularly provides an optimization method for the charging process of an LF refining furnace. The optimization method comprises the following steps that a material list is determined according to the production process, and a weighing treatment stage is conducted; material list data units of a material batch list are loaded into a plurality of corresponding control grid units, after loading is completed, the control grid units weigh materials in corresponding storage bins into corresponding weighing hoppers in parallel, and after weighing is completed, a discharging instruction is waited for feeding; and when the discharging instruction is received, the weighed materials in the weighing hoppers are fed into a target body according to the feeding sequence and conditions, when feeding of all the weighing hoppers is completed, the states of the material list data units and the control grid units are modified, the actual charging performance is recorded, and feeding is finished. The problems that an existing charging method is long in charging time, and the material efficiency is affected are solved. According to the optimization method, the time is shortened, the automation degree is high, the production rhythm is improved, the process energy consumption is reduced, the production cost is reduced, and the production efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of metallurgical technology, and specific to an optimization method of an LF refining oven feeding process. Background technique [0002] LF refining furnace is an essential refining device that smelters high-quality steel, which is mainly used for deoxidation desulfurization to remove non-metal inclusion and temperature and alloy component adjustment, while mechanizing the water heating treatment, the system is complex, and the smelting rhythm is high. Time requirements, you need to minimize processing process equipment assisted working hours, otherwise it will increase energy consumption affecting production efficiency. The treatment of feeding (residue, deoxidation, alloying, etc.) during processing is required to operate according to the progress of the processing. Each time it is added according to the type of material, it is necessary to batch according to the type of material. At present, most of them are tr...
