Vertical continuous casting stainless steel plate blank cutting process method

Abstract

The invention belongs to the technical field of plate cutting processes. According to a vertical continuous casting stainless steel plate blank cutting process method in the specific technical scheme, a starting module, a cutting starting module, a cutting module, an encountering module, a waiting module, a cutting-off module and a zero returning module which are arranged in sequence are included, the action and logic of internal equipment of each functional module and the conversion among the functional modules are fully automatically completed through a programmable controller, the seven modules are matched with one another to complete the cutting of a vertical continuous casting stainless steel plate blank, and in the cutting production of the vertical continuous casting stainless steel plate blank, the stainless steel plate blank is small in cutting seam, smooth in section and good in notch quality; and medium consumption is little, resources are saved, short time is required by one-time cutting, a cutting gun has high efficiency, practicability is high, and the vertical continuous casting stainless steel plate blank cutting process method can be widely applied to vertical continuous casting stainless steel plate blank cutting production in steel mills.

Description

technical field [0001] The invention belongs to the technical field of plate cutting technology, and in particular relates to a cutting technology applied to vertical continuous casting stainless steel slabs. Background technique [0002] At present, at home and abroad, most of the continuous casting machines with sector sections are used in the production of slabs in steelmaking and continuous casting systems. The continuous casting slabs are transformed into horizontal patterns through the sector sections, and then cut. The cutting process is relatively simple. In rare cases, such as the production of high-performance stainless steel slabs, the vertical continuous casting method is adopted at this time, and the cart is cut from the bottom of the crystallizer above to the bottom of the bottom. All equipment is arranged vertically, and the entire stainless steel slab is vertical. For cutting vertical stainless steel slabs (also called stainless steel slabs) that extend downw...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems existing in the vertical continuous casting stainless steel slab cutting process in the prior art, the stainless steel slab cutting seams are large, the cross-section is uneven, the incision quality is poor, the medium consumption is high, resources are wasted, the time required for one cutting is long, and the cutting time is long. Due to the technical problem of low gun efficiency, the invention provides a cutting process for vertical continuous casting stainless steel slabs, which adopts a fully automatic control method without manual intervention, high cutting efficiency and short cutting time
