Abstract

The invention provides a method for producing a patterned plate with the thickness of 1.4mm through the CSP process. The method comprises the steps of (1) conducting conventional smelting, conductingcasting to form a blank and heating the casting blank; (2) conducting finish rolling through a finishing mill rack except a tail rack; pressing patterns on the tail rack; (3) conducting cooling; and (4) conducting winding. By means of the method, on the premise of guaranteeing the application dynamics and attractive appearance of the patterned steel plate, the weight-loss ratio can be made not tobe lower than 10%; the purposes of energy conservation and emission reduction can be achieved; the high market requirements can be met; moreover. The pattern incomplete rate is reduced from original 11% to at most 2%. The plate flattening rework rate is reduced from original 53% to at most 7%. The plate quality is excellent.

Description

technical field [0001] The invention relates to a production method of checkered steel plates, in particular to a method for producing extremely thin checkered steel plates based on a CSP short-flow production line, which can produce checkered steel plates with a minimum thickness of 1.4 mm. Background technique [0002] At present, checkered steel plates are widely used in technical fields such as construction, shipbuilding, transportation and machinery manufacturing because they have good anti-skid and wear-resistant properties and are easy to clean. The shape of the checkered steel plate is mainly lentil-shaped, rhombus-shaped, and round-bean-shaped. Among them, the lentil-shaped pattern is open-shaped, beautiful and generous, with good anti-skid effect, easy to remove water and oil, and high wear-resisting pattern. Generally accepted is the lenticular checkered plate. [0003] The pattern is formed by metal filling the grooves of the roll during rolling, and the height ...
