Abstract

The invention discloses a system for removing slab burrs and belongs to the field of machining of a slab after flame cutting in a steel metallurgical industry. The system is composed of a numerical control plasma arc cutting device, a slab locating device and a siemens programmable logic controller (PLC) control system. The numerical control plasma arc cutting device is formed by two sets of identical components and comprises a plasma power supply, a control cabinet, a first servo motor, a plasma gun body and a traveling mechanism of the plasma gun body. The slab locating device is composed of a traveling mechanism of a front frame and a rear frame, a traveling mechanism of the slab and a lifting control system of the slab. The siemens PLC control system assembly comprises a siemens S7-300 system module, a frequency converter, a hydraulic driver, a servo driver of the front frame and rear frame, a second photoelectric switch, a first photoelectric switch and a communication port. The system integrates high speed of slab burr removing and high burr removing rate and has important application value on controlling rolling quality of the slab.

Description

technical field

[0001] The invention belongs to the field of slab hot rolling and continuous casting and rolling slab flame cutting processing in the iron and steel metallurgy industry, and in particular relates to a device for efficiently removing burrs from a slab by a plasma arc. Background technique

[0002] After the slab is formed by continuous casting and rolling, it must be cut into sections according to a certain length, and then enter the conveying roller table. Because there is an irregular slag (steel billet burr for short) sticking to the edge of the incision during flame cutting, this kind of slag is relatively hard and has strong adhesion. The surface quality of the steel plate does not meet the rolling steel requirements. At the same time, it will cause certain damage to the surface of the roll and affect the life of the roll.

[0003] Among the existing methods for removing burrs from cast slabs, there are scraping (hammer) knife removal methods and flame ...
