Structural layout of a converter feeding operation system

Abstract

The invention discloses a structural layout of a converter charging operation system and a method for coordinated control, which comprises a converter span, a charging span and a main control room span. ; The molten iron feeding position is at the top of the workshop; a furnace loading system is installed at the scrap steel feeding position near the furnace mouth of the converter, and the steel grabbing machine is installed on the platform in front of the furnace; The walking rack on the top is equipped with a hoisting trolley for hoisting the molten iron ladle. The invention can not only realize that the mixing of molten iron and the addition of scrap can be completely staggered in space, and the operation is relatively independent, but also because of the relatively unique feeding system of scrap steel with transport vehicles and steel grabbers, it can also achieve the addition of scrap and mixing of molten iron between multiple converters. The operation is relatively independent and does not interfere with each other, which is convenient for vertical management, which is more conducive to the production scheduling in the workshop, and improves the efficiency of converter charging across the operation.

Description

technical field [0001] The invention relates to the field of converter steelmaking systems, and more particularly, to a method for structural layout and coordinated control of a converter charging operation system, in particular, the operation system is divided into two different spaces with non-overlapping operation trajectories and operation areas. Non-disturbing molten iron system and scrap steel system. Background technique [0002] Iron and steel production is a complex manufacturing process that integrates material state transformation, material property control, and logistics control. The converter steelmaking charging cross-operation system mainly includes: ladle and scrap bucket turnover, ladle driving and scrap steel driving. In order to shorten the converter smelting cycle and maximize the converter smelting efficiency, it is necessary to shorten the waiting and auxiliary time of the operation system, and improve the operation efficiency of the feeding system acro...

Problems solved by technology

According to the search, most steel mills currently carry out technical treatment of scrap steel buckets to reduce the number of scrap steel additions. However, when faced with a large number of converters with the same span, there will be an increase in the phenomenon of wrong vehicles between driving, overlapping operations, and increased interference. solve this problem

The Chinese patent name is: Converter Adding Scrap Steel Device (CN107236840B). This method is to add scrap steel to multiple converters at the same time through the platform in front of the converter furnace. Staggering, so that there is no interference between operations, and the production rhythm of the converter can be improved; however, this method cannot completely stagger the ironing train in space, and at the same time, the device will occupy a large amount of space in front of the furnace platform and require a special track, which consumes a lot of money. Unable to solve the problem caused by the scrap steel stuck in the furnace mouth

In addition, the name of the Chinese patent is: a converter steelmaking system and a method for adding scrap steel and molten iron (CN108486309A). Trajectories do not overlap, thereby improving production efficiency; due to the addition of scrap steel lifting spans, the molten iron running trajectory is closer to the main control room, and at the same time the safety area of ​​the furnace front platform is greatly reduced, which has certain safety hazards; due to the limited height of scrap steel spans , making it difficult to dump steel scrap into the furnace

[0005] To sum up, the above methods do not effectively and stably solve the problem of collaborative control of converter feeding cross-operation system
