Converter feeding operation system structure layout and cooperative control method

Abstract

The invention discloses a converter feeding operation system structure layout and cooperative control method. A device comprises a converter bay, a feeding bay and a main control chamber bay. The feeding bay is divided into a molten iron feeding position and a scrap steel feeding position. The scrap steel feeding position is located on the ground, and the molten iron feeding position is arranged on the top of a workshop. A charging system is arranged at the position, close to a converter mouth, of the scrap steel feeding position, and a steel grabbing machine is installed on a converter frontplatform. The molten iron feeding position is arranged on the top and comprises a travelling truss installed on the top of the workshop in the feeding bay direction, and a hoisting trolley which is used for hoisting a ladle is assembled on the travelling truss. According to the method, the purposes that molten iron adding operation and scrap steel adding operation can be completely alternated in space, and the operation is relatively independent can be achieved; due to the fact that a transport vehicle and a scrap steel feeding system with the unique steel grabbing machine are adopted, the purpose that scrap steel feeding operation and molten iron adding operation conducted among multiple converters are relatively independent and do not interfere with each other can also be achieved, the longitudinal management is facilitated, smooth workshop production scheduling is better facilitated, and the converter feeding bay operation efficiency is improved.

Description

technical field [0001] The present invention relates to the field of converter steelmaking systems, more specifically, to a method for the structural layout and collaborative control of the converter feeding operation system, especially refers to dividing the operating system into two different spaces with non-overlapping operating tracks and operating areas Non-interfering hot metal system and scrap 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 feeding cross-operation system mainly includes: ladle and scrap steel bucket turnover, ladle crane and scrap steel crane. In order to shorten the converter smelting cycle and maximize the efficiency of converter smelting, it is necessary to shorten the waiting and auxiliary time of the operation system and improve the operation efficiency of the cross-system fe...

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
