Controlling method and controlling system for charging of main raw material of converter

Abstract

The invention provides a controlling method and a controlling system for charging of a main raw material of a converter. According to the method, charging amount of molten iron and steel scrap is calculated in advance and controlled based on different types of steel to be smelted and equipment difference, compiling of a molten iron and steel scrap weighing command is guided, and controlling of molten steel components is guaranteed. With the controlling method and the controlling system provided by the invention, charging amount of the main raw material of each converter can be automatically calculated after a production plan is issued, steel ladle weight information and production process standard information of each type of steel are acquired as calculation bases, and the process of calculation is closely associated with the production plan and equipment; and auto-correction and feedback can be automatically carried out on a scheduled charging amount of the main raw material when conditions like the type of steel, a converter base and steel ladle weight change, and correction of scheduled weighing information of a molten iron and steel scrap weighing system can be automatically realized, thereby guaranteeing accuracy of charging amount of the main raw material.

Description

technical field [0001] The present invention relates to the field of metallurgy. Specifically, the present invention relates to a converter smelting control method and its control system. More specifically, the present invention relates to a converter main raw material loading control method. The main raw material loading control method of the converter automatically corrects the predetermined value of the loading amount according to the production plan and the adjustment of the equipment, guides the preparation of the weighing action instructions of molten iron and scrap steel, and ensures the control of the composition of molten steel. Background technique [0002] The main raw materials for converter steelmaking mainly refer to molten iron and scrap steel loaded into the converter. The amount of molten iron and steel scrap needs to be calculated in advance depending on the type of steel being smelted and the condition of the equipment. The control of molten iron and stee...

AI Technical Summary

Problems solved by technology

In fact, equipment and production requirements will often change during the process of smelting molten steel in the converter, resulting in deviations between the calculated loading amount and the actual requirements.

[0009] (3) In order to improve work efficiency, the parameters set by the operator should not be too many, so some factors such as empty bag weight, refining method and other factors cannot be considered one by one, which also affects the accuracy of the calculation of loading capacity

[0010] 2. Cannot be corrected automatically

[0011] The operating area of ​​the converter is scattered. When the production plan or equipment is adjusted, the loading amount of the main raw material cannot be corrected in time. If the weighing has already started at this time, the weighing operation can only be carried out according to the original data, which will cause the amount of molten steel to fluctuate. fluctuation
