Embodiment 1

[0017] Embodiment one. the method for rolling stainless steel precision strip steel with Sendzimir rolling mill

[0018] On the basis of the existing rolling process regulations of the 20-high Sendzimir rolling mill, add the technical regulations for rolling thickness below 0.3mm, and carry out reasonable configuration of the roll system, and calibrate the inspection instruments such as thickness gauges and shape gauges , fully meet the requirements for the production of stainless steel precision strip below 0.3m. The method of rolling stainless steel precision strips with Sendzimir rolling mills in this example has been successfully used in a steel company to produce and roll 0.25mm stainless steel precision strips. The method it adopts is specifically:

[0019] 1. The deformation rate of each pass should be allocated reasonably, and the deformation rate of each pass is set as follows: 20% for the first pass, 15% for the second pass, 12% for the third pass, 10% for the fourth...

Embodiment 2

[0026] Embodiment two. The method for rolling stainless steel precision strip with Sendzimir rolling mill

[0027] The method of rolling stainless steel precision strip steel with a Sendzimir rolling mill in this example was successfully used in a certain steel company to produce and roll 0.2mm stainless steel precision strip steel. The method it adopted was specifically:

[0028] 1. The pass deformation rate is set as follows: 20% for the first pass, 15% for the second pass, 11% for the third pass, and 9% for the finished pass;

[0029] 2. The configuration of the roller system is: two intermediate free rollers with 12 upper and lower crowns, and one intermediate roller uses compound double taper. The grinding process is: the first section of the cone is 230mm long and the taper is 0.25%; the second section of the cone is 100mm long. Taper 0.14%, please refer to the attached manual figure 1 , 2 ;

[0030] 3. The operation of an intermediate roll after replacing the work ro...

Embodiment 3

[0033] Embodiment three. The method for rolling stainless steel precision strip with Sendzimir rolling mill

[0034]The method of rolling stainless steel precision strip steel with Sendzimir rolling mill in this example has been successfully used in a certain iron and steel enterprise to produce and roll 0.15mm precision strip steel. The method it adopts is specifically:

[0035] 1. The pass deformation rate is set as follows: 22% for the first pass, 18% for the second pass, 16% for the third pass, 13% for the fourth pass, and 11% for the finished pass;

[0036] 2. The configuration of the roller system is: two intermediate free rollers with 8 upper and lower crowns, and one intermediate roller uses compound double taper. The grinding process is: the first section of the cone is 220mm long and the taper is 0.18%; the second section of the cone is 100mm long, Taper 0.10%;

[0037] 3. The operation of an intermediate roll after replacing the work roll: After replacing the work ...

Abstract

The invention discloses a method for rolling precision stainless steel strips with a Sendzimir rolling mill, which belongs to the field of stainless steel technology and steel rolling. In the method, a process regulation of rolling a strip with the thickness less than 0.3 mm is added on the basis of the prior rolling process regulations of a twenty high rolling mill; a computer system is adopted to perform control and rational roll system configuration so as to rationally assign the deformation rate of each pass and prevent the problems that strings of edge waves of the steel strip are drawn, or tension sides are ripped and broken, and string drawing easily occurs when the rolling mill is started; checking apparatuses, such as a thickness gauge, a plate shape gauge and the like, are corrected; and the surface conditions and the like of the rolled steel strip are checked in advance of two passes so as to comprehensively meet the requirements of producing the precision stainless steel strips of less than 0.3 mm. The method not only expands the rolling range of the twenty high Sendzimir rolling mill, but also can produce products with high value added and reduce investment cost of new precision rolling mills, and is good for producing and rolling the precision stainless steel strips with short time, higher speed and lower cost, and has great application and popularization values in the manufacturing industry.

Description

1. Technical field [0001] The invention discloses a method for rolling stainless steel precision strip steel with a Sendzimir rolling mill, which belongs to the field of stainless steel technology and steel rolling technology, and specifically relates to a method for rolling a stainless steel precision strip steel thinner than 0.3mm with a Sendzimir rolling mill method. 2. Background technology [0002] Stainless steel precision strip (generally refers to products with a thickness less than 0.5mm) is widely used in industries with special needs such as information technology, computers, auto parts, medical treatment, metal hoses, semiconductors, etc., and is a high value-added product. . Therefore, the production of stainless steel precision strip has very broad prospects. At present, the production of stainless steel precision strip mainly relies on special precision strip rolling mills. The strip steel produced not only has high thickness precision, but also has very go...
