Figured plate rolling arrangement roller mode and its figured plate rolling method

Abstract

A roller matching pattern for hot continuous tandem mill checked plate rolling and the diamond plate rolling method; the roller matching pattern is characterized in that the relationship between the diameters of a checked roller and a flat roller is that the nominal diameter of the checked roller is equal to the sum of the diameter of the flat roller and twice of the beam height and the forward sliding distance value. The rolling method of the checked plate comprises the steps of heating continuous casting plate base; rough rolling; fine rolling and winding; the present invention is characterized in that the relationship between the diameters of a checked roller for fine rolling and a flat roller is that the nominal diameter of the checked roller is equal to the sum of the diameter of the flat roller and twice of the beam height and the forward sliding distance value; the checked roller is equipped under the flat roller in the process of fine rolling and the reduction percent is 9 to 25 percent in the process of fine rolling. The roller matching pattern for the hot continuous tandem mill checked plate rolling can enlarge the product specification of the checked plate which is easy to master; the reduction percents for checked plates with base plates of different thicknesses are provided with this checked plate rolling method which can prevent the roller from falling off and the accident from happening because of the overload operation of the roller main shaft.

Description

technical field [0001] The invention relates to a pattern plate rolling roll matching method and a pattern plate rolling method thereof. Background technique [0002] Checkered plate is widely used in construction, transportation, and public places as a non-slip steel plate. In GB709-88, there are various specifications, and its thickness ranges from 1.5mm to 12.7mm. The rolling of the hot rolling mill is the main process of producing the checkered plate, and the ratio of the diameter of the flat roll of the hot-rolled checkered plate to the diameter of the checkered roll, that is, the matching method of the flat roll and the checkered roll, is the key to the hot-rolled checkered plate. After the billet is hot-rolled into a patterned plate, its thickness is thinned. The ratio of the diameter of the flat roll to the diameter of the patterned roll varies with the bean height of the patterned plate and the thickness of the steel plate. Therefore, the ratio of the diameter of th...

Problems solved by technology

Now domestic rolling mills generally only consider the forward slip value of the flat roll, that is, the nominal diameter of the patterned roll = the straight length of the flat roll + 2 times the forward slip value of the flat roll; some rolling mills match the patterned roll on the upper roll, and the roll diameter increases 2.5mm, when rolling checkered plates, the output is not large, the quality is unstable, the bean height is difficult to guarantee, and the rolls are prone to peeling off, and it is only suitable for checkered plates with a thickness of 3.0-6.0mm, which has great limitations and limited application range. Difficult to master implementation
