Pickling plate is a high quality hot rolled sheet as raw material, after pickling unit to remove the oxide layer, cutting, finishing, surface quality and use requirements (mainly cold bending forming or stamping performance) between the hot rolled plate and cold rolled plate intermediate products, is part of the hot rolled plate and cold rolled plate ideal alternative products; Rolled hard plate is hot rolled steel coil after pickling to remove the oxide skin for cold continuous rolling, because of continuous cold deformation caused by cold hardening and not through annealing treatment, the strength and hardness of steel plate increased, the toughness and plastic index decreased, so the mechanical processing performance is poor, can only be simple and directional bending processing.

The representative brands of longsheng plate pickling and rolling include SPHC, SPHD, SPHE, spcc-1b, spcc-2b, spcc-pt, etc. The implementation standards are: Q/LSB 02-2019 cold rolled low carbon steel plate and steel strip (JIS), Q/LSB 03-2019 cold rolled low carbon steel plate and steel strip (DIN, EN), Q/LSB 04-2019 cold rolled steel plate and steel strip size, shape, weight and allowable deviation, Q/LSB 06-2019 cold rolled low carbon steel plate and steel strip, Q/LSB 06-2019 cold rolled low carbon steel plate and steel strip, jb-t 6978-1993 surface preparation pickling technical requirements.

Pickling material terminal use products are all kinds of steel box cabinet, hardware products, highway guardrail, compressor shell, car ring, rolling coil is mainly used for galvanized substrate and other ordinary forming, terminal use products building materials, umbrella frame and welded pipe.
