Problems solved by technology

[0003] Due to the low output of stainless steel, high technical requirements for electrical control, and flexible production in separate layouts, the products of stainless steel hot-rolled coils (black coils) after pickling are No.1 plates, which can be directly sold and applied. No existing equipment is suitable for mass production 2B / Economical production of 2D surface cold-rolled products

Embodiment Construction

[0022] specific implementation plan

[0023] Attached below figure 1 , to further describe the continuous production system and method of stainless steel cold-rolled plate of the present invention.

[0024] in such as figure 1 The shown continuous production system for stainless steel cold-rolled plates includes a first uncoiler 1, a second uncoiler 2, a welding machine 3, a hot zone pickling inlet looper 4, a black coil pickling section 5, a rolling mill inlet looper 6, Continuous rolling mill 7, cleaning section 8, rolling mill exit looper 9, cold plate annealing furnace 10, cold strip pickling section 11, cold strip pickling exit looper 12, temper mill 13, tension leveling and inspection looper area 14, Coiler 15.

[0025] The first uncoiler 1 and the second uncoiler 2 have the ability to uncoil the steel strip with a thickness of 1mm~8mm. The welding of the strip head and strip tail is completed at the welding machine 3. The laser welding machine has good weld quality a...

Abstract

The invention discloses a stainless steel cold-rolled plate continuous production system and method. The stainless steel cold-rolled plate continuous production system at least comprises a black rollpickling unit, a stainless steel white roll rolling unit and an annealing pickling unit which are sequentially connected to form a continuous unit; and a middle annealing section is arranged between the black roll pickling unit and the stainless steel white roll rolling unit. Multiple procedures of black roll pickling, stainless steel white roll rolling, annealing pickling and the like are connected to form the continuous unit to directly produce a 2B / 2D product; black roll annealing, intermediate annealing and inter-procedure steel roll conveying are omitted; the yield is improved; and factory construction occupation area and construction investment are reduced to a great extent.

Description

technical field [0001] The present invention mainly relates to the technical field of production of stainless steel strips, in particular to stainless steel black coils (stainless steel hot-rolled coils with scale on the surface) pickling, white plate (hot-rolled, heat-treated stainless steel without scale after pickling, see Chinese national standard GB -T4237-2007 Article 6.6 of the abbreviation 1D volume, or the NO.1 plate collectively referred to in the industry (see Baoshan Iron and Steel Co., Ltd. Enterprise Standard Q / BQB 4302-2009)) rolling, cold plate annealing, cold plate pickling and A continuous production unit and method in which surface finishing and other processes are combined. Background technique [0002] Stainless steel black coil pickling, white plate rolling, cold plate annealing, cold plate pickling and surface finishing are all mature production processes. Stainless steel hot-rolled coils (black coils) have thick oxide scales and are difficult to rem...
