A strip production system and method

Abstract

The invention discloses a strip steel production system and a strip steel production method. The system at least comprises strip steel height adjustment equipment, a two-roller coating machine and drying equipment; the strip steel height equipment, the two-roller coating machine and the drying equipment are arranged on a strip steel production line in sequence; the strip steel is arranged on the strip steel height adjustment equipment, and enters the drying equipment through the two-roller coating machine. The purpose of adjusting the thickness of a coating on the surface of the strip steel is adjusted by adjusting the height of the strip steel; if the coating of the upper surface of the strip steel is thick, the height of the strip steel is reduced, and if the coating of the lower surface of the strip steel is thick, the height of the strip steel is lifted, so that the uniformity of the thickness of the coating of the strip steel in the longitudinal direction is improved; on one hand, the content of free chromium is reduced so that the requirement on environment friendliness is met, and moreover, the income reduction of caused by degradation products can also be avoided; on the other hand, the consumption of coating rollers and a coating liquid is also reduced, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a strip steel production system and method. Background technique [0002] Cold-rolled non-oriented silicon steel is an important raw material product in my country's household appliances, small and medium motors, large motors, electronic products and other industries. The quality of its surface coating directly affects the punching, stacking and insulation of motors or motor cores. resistance, etc. [0003] With the gradual upgrading of customer products, especially in the production of large motors, the insulation performance of the coating is extremely demanding. In order to meet the individual needs of customers and increase market share at the same time, it is necessary to actively respond to the requirements of customers, and to change the thickness of the coating as a measure to meet the high requirements of customers for insulation performance. [0004] As the coating thi...

Problems solved by technology

However, the current CA5-6 unit products have high free chromium content and poor stability, up to 5000ppm, resulting in the inability of stable supply of some products and need to be downgraded, which greatly increases the production cost and reduces the production cost of Shougang’s silicon steel products.
