Embodiment 1

[0072] Take converter 5071212 as an example.

[0073] (1) The L2 reference heat group definition storage module defines reference heat group standards and stores them in the L2 database correlation table.

[0074] ① Definition of grouping rules

[0075] L2 refers to the grouping of furnaces, and according to the target composition of phosphorus, target carbon, and target slag, it is divided into three definitions. The definition mode is as follows:

[0076]

[0077] ②Group parameter definition data storage

[0078] Create a table in the L2 database, store the relevant parameters of the group, and provide corresponding maintenance changes, and the process engineer can perform maintenance according to the process requirements. As shown in the table below.

Abstract

The invention relates to a converter smelting control device based on referenced heat grouping. The converter smelting control device based on the referenced heat grouping comprises an L2 referenced heat grouping definition storage module, an L2 heat state judgement module, an L2 data collection module, an L2 heat group judgement module, an L2 referenced heat data extraction module, an L2 model calculation module, an L2 production control module, an L1-L2 communication module, an L1 converter production control module and a referenced heat data storage module, wherein L1 is a basic automationcontrol system and controls running of the device through a PLC (programmable logic controller) program, and L2 is a converter process control system and used for process control of production. By adopting the technical scheme, the converter smelting control device based on the referenced heat grouping achieves that during the calculation process of a converter model, grouping can be performed according to difference of target P, target C and heat target slag quantities, performs control according to the grouping, and improves hit rate of the target C and temperature of a converter end point.

Description

technical field [0001] The invention relates to a control device, in particular to a converter smelting control device based on reference furnace grouping, and belongs to the technical field of converter smelting. Background technique [0002] The static model of the converter is mainly based on the properties such as the composition and temperature of the initial molten iron, the amount of scrap added and the target composition and temperature of the molten steel, etc., to calculate the auxiliary materials, total oxygen blowing amount, ore, etc. that need to be added to this furnace, as an automatic tool for converter steelmaking. in accordance with. During the smelting process, there are differences in the temperature rise coefficient and decarburization coefficient of different steel types, resulting in that the hit rate of the end point cannot be greatly improved. The traditional method of grouping according to carbon content is based on the premise of calculating the a...
