Problems solved by technology

The design and production capacity of the original production line of precision strip steel in China can only produce 508mm coil diameter coils, and does not have the ability to produce 152mm and 76mm coil diameters, and cannot meet the requirements of some domestic and foreign customers for finished coil diameters.
It is extremely difficult to produce ultra-thin stainless steel precision strip below 0.05mm, especially in the recoil production of wide thin strip with a width ≥ 400mm, it is very easy to cause strip draw and breakage, and it is difficult to ensure tight and even coiling, which seriously restricts The market share of the company's products in the field of ultra-thin stainless steel

Abstract

The invention discloses a control system and method for changing diameters by coiling ultra-thin stainless steel strips. The method comprises the following steps: steel coils which need to be recoiledare transported to an uncoiling machine by a coil stripping car; coiling blocks of the uncoiling machine expand to fix the steel coils, and uncoiling is performed; strip steel obtained after uncoiling reaches a coiling machine via a crease-resistant roller, and the head part of the strip steel is fixed by the coiling machine to finish strip threading; the coiling machine and the uncoiling machinerun to perform recoiling; and the coiling machine and the uncoiling machine stop running after the length or weight of the strip steel on the coiling machine reaches the preset requirement. Accordingto the control system and method for changing the diameters by coiling the ultra-thin stainless steel strips, by coiling and recoiling the steel strips, the coil diameters of the steel coils can be changed; the steel coils of preset coil diameters are obtained to meet the needs of different clients, and the application range is relatively broad; direct tension control is employed; direct tensioncreation is performed on the uncoiling machine and the coiling machine; the dynamic torque and the mechanical loss torque of the uncoiling machine are compensated in real time; drawn or broken stripsare not generated in the whole process; tension control is stable; the requirement of changing the diameters by coiling is met; and the production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of steel strip coiling, in particular to a system and method for controlling the variable diameter of ultra-thin stainless steel strip coiling. Background technique [0002] Ultra-thin stainless steel strips have entered aerospace, medical electronics, communication semiconductors, auto parts and other fields, and have very high added value. The design and production capacity of the original production line of precision strip steel in China can only produce 508mm coil diameter steel coils. It does not have the ability to produce 152mm and 76mm coil diameters, and cannot meet the requirements of some domestic and foreign customers for finished coil diameters. It is extremely difficult to produce ultra-thin stainless steel precision strip below 0.05mm, especially in the recoil production of wide thin strip with a width ≥ 400mm, it is very easy to cause strip draw and breakage, and it is difficult to ensure tig...
