Steel ladle argon intelligent connecting system and control method

Abstract

The steel ladle argon intelligent connecting system and a control method. The intelligent connecting system comprises an automatic air inlet butt joint device, a steel ladle bearing device and a control device, wherein the automatic air inlet butt joint device comprises an air inlet air cylinder and a butt joint, the butt joint is fixed to the end of a piston rod of the air inlet air cylinder, and the piston rod and the butt joint are provided with a through air inlet channel; the steel ladle bearing device comprises a bearing head, the bearing head is fixed to a steel ladle, a through hole is formed in the bearing head and correspondingly communicated with a steel ladle air inlet tube, and a butt joint cavity is formed in the outer side of the through hole and matched with the butt joint; the control device comprises a controller and a pressure sensor, the pressure sensor is installed in the butt joint, the input end of the controller is connected with an upper computer and a pressure sensor, and the output end of the controller is connected with the air inlet air cylinder. The whole system is simple in structure and reliable in control, and the steel ladle argon intelligent connection and control are achieved by adopting a lateral argon connection mode.

Description

technical field [0001] The invention belongs to the technical field of argon blowing at the bottom of a ladle, and in particular relates to a ladle argon intelligent connection system and a control method. Background technique [0002] Argon blowing at the bottom of the ladle is the most widely used external refining method at home and abroad. It can not only effectively uniform the composition and temperature of molten steel, but also remove inclusions in molten steel and improve the quality of molten steel. The stable operation of the ladle argon connection system is the prerequisite for the realization of the argon blowing process at the bottom of the ladle. The existing problems are as follows: [0003] ①The advantage of the manual quick connector type is that the equipment is simple and the connection rate is high, but because of the manual connection, the working hours are long, the working environment is harsh, and it is easy to be damaged by ladle slag during operati...

AI Technical Summary

Problems solved by technology

[0003] ①The advantage of the manual quick connector type is that the equipment is simple and the connection rate is high, but because of the manual connection, the working hours are long, the working environment is harsh, and it is easy to be damaged by ladle slag during operation. personal injury

[0004] ②Bell-type automatic joint type is automatically connected through the female connector installed on the edge of the ladle and the male connector installed on the edge of the trolley. There are many accessories, which are easy to collide and slag. Moreover, due to the high positioning accuracy requirements and the large impact load during the equipment connection process, the equipment failure rate is high, the connection success rate is low, and the maintenance workload is large.

[0005] ③ Flat automatic joint type, although fully automatic connection can be realized, but the heat resistance of the sealing ring is not good, the failure rate is high, and this method has high requirements on the cleanliness of the reference surface of the trolley, once the reference surface has sticky slag, etc. , the system will not automatically receive argon

[0006] At present, there is no relevant technology and control method that can effectively realize the intelligent connection of the ladle bottom blowing argon gas supply system
