Collocation method of iron ores of steel raw material field

Abstract

The invention provides a collocation method of iron ores of a steel raw material field and belongs to the field of a metallurgical industry. In the optimized collocation method disclosed by the invention, the input collocations of various types of the iron cores and strict component control requirements of the iron cores are comprehensively considered so as to assist collocation planning personnel to find out the best storage way, thus improving the production and storage quality of the iron ores, and realizing the purposes of guaranteeing the supply of the iron ores, reducing the transportation energy consumption, preventing the iron ores from being mixed, guaranteeing the quality of the iron ores, improving the quality of a subsequent product and on the like. By comparing an artificial collocation result of actual data with an optimized result, on the premise that the input executing rate of the iron cores is improved by 2.7%, a target function can be obviously reduced by 12.79% by comparing an optimized collocation scheme with an artificial collocation scheme, so that the consumption of the transportation energy loss is effectively reduced, the storage quality of the iron ores is improved and the quality of subsequent products is further improved.

Description

technical field [0001] The invention belongs to the field of metallurgical industry, relates to the technical field of iron and steel raw material logistics information, and in particular relates to a method for configuring iron ore in a steel raw material yard. Background technique [0002] The raw material yard of iron and steel enterprises is used to store bulk raw materials such as iron ore required by blast furnaces, sintering and other production units. There are hundreds of types of raw materials (mainly iron ore) stacked in the raw material yard, which are stacked in different strips in the open air in the form of piles according to their respective rules. Each strip has a corresponding reclaimer and stacker to serve it. The raw material field uses the stacker and reclaimer equipment to allocate raw materials to reasonable storage positions, and supplies materials for the production processes such as blast furnace and sintering. The schematic diagram of the raw mate...

Problems solved by technology

[0004] At present, the process of raw material input and configuration in domestic iron and steel raw material yards is all arranged manually according to experience. The characteristics of large material time fluctuations, large feed volume, fast turnaround time, fast dynamic update of basic information of the stockyard, complex operation steps, strict protection of raw material components, many constraints, and high randomness make the configuration of raw material input a very important task. It is tedious and time-consuming work that needs to be repeated continuously. At the same time, the manual planning cannot take into account the requirements of production capacity, raw material quality, logistics balance, and demand satisfaction. It is often impossible to comprehensively consider the current and future feeding conditions. To adjust the stockyard layout plan in real time, temporary expedient processing is often adopted, so it is difficult to make reasonable arrangements for the batch incoming raw material allocation by manual methods alone
