Embodiment 1

[0027] A kind of production method of ultra-thin stainless steel strip of the present invention, it comprises the following steps:

[0028] The first step: raw material preparation; select a stainless steel strip blank with a thickness of 3.0mm and a width of 560mm;

[0029] The second step: the first rolling process: the steel coil is transported into the uncoiler by the crane and the steel coil trolley, and enters the rolling mill after uncoiling. After the lead is clamped by the jaws of the coiler for two coils, the tension KN: 9 is established, and Give a certain amount of reduction, and then the uncoiler, rolling mill, and coiler are raised to the rolling speed for steady rolling. The steel strip rolling speed is 120 meters per minute. When a coil is almost finished rolling, carry out uniform deceleration rolling until the stop, reverse after stop, and then carry out reverse rolling, the steel strip rolling speed: 120 m / min; repeat the reversible rolling in this way, cold...

Embodiment 2

[0042] A kind of production method of ultra-thin stainless steel strip of the present invention, it comprises the following steps:

[0043] The first step: raw material preparation; select a stainless steel strip blank with a thickness of 3.0mm and a width of 500mm;

[0044] The second step: the first rolling process: the steel coil is transported into the uncoiler by the crane and the steel coil trolley, and enters the rolling mill after uncoiling. After the lead is clamped by the jaws of the coiler for three turns, the tension KN: 8 is established, and Give a certain amount of reduction, and then the uncoiler, rolling mill, and coiler speed up to the rolling speed for steady rolling. The steel strip rolling speed is 110 m / min. When a coil is almost rolled, carry out uniform deceleration rolling until the stop, reverse after stop, and then carry out reverse rolling, the rolling speed of the steel strip: 110 m / min; repeat the reversible rolling in this way, cold rolling 7 pass...

Embodiment 3

[0057] A kind of production method of ultra-thin stainless steel strip of the present invention, it comprises the following steps:

[0058] The first step: raw material preparation; select a stainless steel strip blank with a thickness of 2.5mm and a width of 425mm;

[0059] The second step: the first rolling process: the steel coil is transported into the uncoiler by the crane and the steel coil trolley, and enters the rolling mill after uncoiling. After the lead is clamped by the jaws of the coiler for three turns, the tension KN: 8 is established, and Give a certain amount of reduction, and then the uncoiler, rolling mill, and coiler are raised to the rolling speed for steady rolling. The steel strip rolling speed is 100 m / min. When a coil is about to be rolled, carry out uniform deceleration rolling until the stop, reverse after stop, and then carry out reverse rolling, the strip rolling speed: 100 m / min; repeat reversible rolling in this way, cold rolling 6 passes . The...

Abstract

The invention relates to a production method of an ultrathin stainless steel band, which comprises the following steps of: selecting a stainless steel band blank; carrying out primary rolling process, annealing, secondary rolling process, annealing, third rolling process, degreasing and annealing by adopting a twenty-roller reversible precise roll train so that the stainless steel band with thickness of 3mm as the raw material is rolled into a stripe stainless steel band as a semi-finished product with thickness of 0.1mm, wherein the thickness tolerance of the stainless steel band as the semi-finished product is +/-0.005mm; smoothing and re-coiling, and shearing the stripe stainless steel band as the semi-finished product to reach the width specification required by a user; and finally, checking and packaging and storing. The production method has the advantages of compact procedure, high rolling precision and high yield of the ultrathin stainless steel band, high band thickness precision, straightness and rolling speed of the cold-rolled steel band and high deep drawability and strength of the steel band.

Description

technical field [0001] The invention belongs to the field of production methods of stainless steel strips, in particular to a cold rolling process of ultra-thin stainless steel strips. Background technique [0002] From the perspective of the application of downstream products in the stainless steel industry chain, stainless steel has entered the automotive industry, shipbuilding industry, rolling stock and rail transit fields, construction fields, petrochemical industry, pharmaceutical and food fields, and electronic information industry fields. Corrosivity, material ultra-thin precision, plate shape and plate thickness tolerance, etc. put forward higher requirements, and also put forward higher requirements for the equipment capacity and adaptability of the cold rolling mill. [0003] In the future, the development direction of cold-rolled stainless steel enterprises should be based on precision ultra-thin plates with a bandwidth of ≥600mm to meet the needs of automotive ...
