等产品。

1800冷轧以生产市场紧缺的高附加值汽车板、家电板等冷轧板带产品为目标，

采用了当今世界成熟的先进工艺技术，设备配置先进、高效、可靠，其中主体

机械设备技术分别从日本三菱—日立公司、新日铁公司、川崎制铁公司和德国

乔格公司引进。1800工艺处理机组(连退及热镀锌机组)采取了诸多张力控制技

术，如前馈控制、速度调节器(ASR)增益在线补偿控制、速度、电流双基准设

定控制等，以实现快速稳定通板。热镀锌机组采用刷辊刷毛对带钢进行研磨的

技术，特别是对GA产品，可以大大提高镀锌后锌层质量；采用两种退火制度，

可有效防止炉内带钢产生瓢曲等缺陷；退火炉采用缓冷段和急冷段结合的两段

冷却技术，可以防止带钢出均热段因带钢急冷造成的热瓢曲现象；设计有全自

用，确保了工艺机组能够稳定生产出高质量的汽车板。

With principal equipment imported from Germany, Japan and U.S. in packages, the No.1 cold rolling mill plant comprises of a pickling line, a 2030mm ?ve-stand continuous cold rolling line, batch annealing furnaces, a single-stand four-high skin pass mill line, a six-zone continuous annealing and pickling line, cross cutting, slitting and recoiling lines, a continuous hot dip galvanizing line and an electrogalvanizing line. The pickling line can effectively remove scales from hot rolled coil surfaces by means of shallow tank pickling with HCl. The cold rolling mills are attached with AGC system and the latest pro?le measuring & adjustment devices and applied with CVC technology, as ensures thickness accuracy and strip pro?le. The CAPL reduces its production cost, increases its production ef?ciency and is able to make products of excellent surface quality and performance by accomplishment of once-through cleaning, recrystallization annealing and skin passing. All lines adopt computer control.

With principal equipment imported from Japan, German and Austria, the No.3 cold rolling mill plant further got its equipment and technical level increased on the basis of No.1 cold rolling mill plant in view of some special requirements of automotive sheets. An advanced combined pickling-rolling line with jet ?ow pickling more effectively removing scales on strip surface is arranged in the plant. Its new type six-high UCMW cold rolling mills can control strip thickness and pro?le more precisely. Its roll cooling type CAL allows for making of higher surface quality products of various performances. On its new type continuous electrogalvanizing and hot dip galvanizing line, various Zn-Ni alloy and heavy electrogalvanizing products and Zn-Fe alloy and zero spangle hot-dip galvanized products are made for automobile use.Its principal mechanical equipment technologies are respectively introduced from Mitsubishi – Hitachi, NSC and Kawasaki from Japan as well as Geogle from Germany. The 1800mm process treatment line (continuous annealing and hot dip galvanizing line) adopts many tension control technologies such as feedforward control, online compensation control of speed regulator gain (ASR) and speed-current double-benchmark setting and control for quick and stable strip passing. The hot dip galvanizing line may greatly enhance galvanizing coating thickness of galvanized products especially GA products by means of application of grinding technology with brush rolls, and effectively prevent defects such as buckles on strips inside the furnace with application of two annealing systems. The annealing furnace adopts the two-zone (slow cooling zone and quick cooling zone) combined cooling technology, which may prevent hot buckles due to quick cooling of strips after the soaking zone. Automatic slow zinc charging equipment is designed in the line and automatic sucking technology for ?oating slag and control technology for settled slag in furnace nose are taken. The application of these technologies ensures the process line for stable production of high-quality automotive sheets.

冷轧低碳钢和超低碳钢按用途可分为一般用、冲压用、深冲压用、特深冲压用、超深冲压用，宝钢生产的低碳和超低碳冷轧钢板，由于具有良好的冲压性能、焊接性能以及较高的尺寸精度，因而被广泛用于制造各种汽车零部件。特别是无间隙原子钢（IF钢）因具有高的r值、n值和伸长率，目前已大量用于门

内板、行李箱盖板、油底壳等极难冲件。用途特点如下表：

一般用 (CQ)具有足够的延展性，适用于简单成型、弯曲或焊接加工

DC01, SPCC, BLC 冲压级 (DQ)具有比一般用级较大的延展性，适用于制造冲压成型及较复杂变形的零部件

DC03, SPCD, BLD 深冲压用 (DDQ)具有比冲压级更大的延展性，更为均匀的性能；适用于制造深冲压成型及复杂变形的零部件DC04, SPCE, BUSD 特深冲压用 (EDDQ)具有比深冲压级更大的延展性，更为均匀的性能，适用于制造特深冲压成型及更为复杂变形的零部件

DC05, BUFD 超深冲压用 (SEDDQ)

具有比特深冲压级更为优异的冲压性能，适用于制造超深冲成型及极复杂的变形的零部件

1.1.1 Low carbon and ultra-low carbon steel plates and strips

According to application, the cold rolled low carbon steel and ultra-low carbon steel can be divided into common quality, drawing quality, deep drawing quality, extra-deep drawing quality and supreme extra-deep drawing quality. With excellent drawing and welding performance and relatively high dimensional accuracy, the cold rolled low carbon and ultra-low carbon steel plates of Baosteel have been widely applied to manufacture of various automotive parts. The interstitial free steel [IF steel] in particular has been greatly used for extremely hard drawing parts such as inner door plates, luggage boot cover plates and crankcase oil

pans for its high value r, value n and percent elongation. See following table for their applications and features:

Commercial

purposes (CQ)

With some ductibility, they are suitable to simple forming, bending or welding.DC01, SPCC, BLC

Drawing (DQ)With more ductibility than the common ones, they are suitable to manufacturing parts through drawing

and relatively complicated deforming.

DC03, SPCD, BLD

Deep drawing (DDQ)With more ductibility and homogeneity than the drawing ones, they are suitable to manufacturing parts

through deep drawing and complicated deforming.

DC04, SPCE, BUSD

Extra-deep drawing (EDDQ)With more ductibility and homogeneity than the deep drawing ones, they are suitable to manufacturing

parts through extra-deep drawing and more complicated deforming.

DC05, BUFD

Supreme extra-deep drawing (SEDDQ)With more excellent drawing capability than the extra deep drawing ones, they are suitable to

manufacturing parts through supreme extra-deep drawing and extremely complicated deforming.
