Embodiment 1

[0030] A checkered plate roll of the present embodiment has a roll body diameter of 700 mm, a roll body length of 1830 mm, and a pattern embossing groove engraved within a middle width of the roll body surface of the roll within a range of 1630 mm.

[0031] The pattern embossing groove on the surface of the roll is lentil-shaped, and the pattern pressed on the steel plate is lentil-shaped. The notch edge of the pattern embossing groove is composed of two symmetrical circular arcs. The length L of the notch of the pattern embossing groove is 35mm, and the width W of the notch is 5mm. The angle α between the two groove side surfaces inside the groove is 80 degrees, and the bottom of the two groove sides is smoothly connected by an arc with a radius R of 2.5mm. The maximum depth of the groove bottom of the pattern pressure groove is H 1 is 4mm.

[0032] The lentil-shaped embossing grooves on the surface of the roll are set horizontally and vertically alternately, and the distanc...

Embodiment 2

[0034] A checkered plate roll of the present embodiment has a roll body diameter of 637 mm, a roll body length of 1830 mm, and a pattern embossing groove engraved within a middle width of the roll body surface of the roll within a range of 1630 mm.

[0035] The pattern embossing groove on the surface of the roll is lentil-shaped, and the pattern pressed on the steel plate is lentil-shaped. The notch edge of the pattern pressing groove is composed of two symmetrical arcs. The length L of the pattern pressing groove is 30mm, and the width W of the notch is 10mm. The groove bottom of the pattern pressing groove along the length direction is arc-shaped. The angle α between the two groove side surfaces inside the pressure groove is 82.5 degrees, the bottom of the two groove sides is smoothly connected by an arc with a radius R of 3.5mm, and the maximum depth H1 of the groove bottom of the pattern pressure groove is 4.5mm .

Embodiment 3

[0038] A method for using a checkered plate roll in this embodiment includes the following process steps,

[0039] (1) Slab pretreatment, heating a slab of a certain thickness to the rolling temperature and holding the hot slab for a certain period of time, wherein the thickness of the slab is 25mm, the rolling temperature is 1150°C, and the holding time is 150min.

[0040] (2) The parameters of the rolling mill are set. The patterned plate roll in Example 1 is used as the upper roll and the flat roll is used as the lower roll. The thickness of the rolled plate between the two roll surfaces is adjusted, and the thickness of the rolled plate is 1.9 mm.

[0041] (3) Roll the checkered plate, put the processed slab into the rolling mill, and roll the checkered plate at a speed of 8m / s~11m / s.

[0042] The pass rate of the rolled checkered plate is 97.2%.

Abstract

The invention discloses a checkered plate roller. The surface of the roller is provided with lentil-shaped figure pressing grooves and is characterized in that the opening edge of each figure pressing groove is composed of two arcs which are symmetrical to each other, the opening lengths of the figure pressing grooves range from 30 mm to 35 mm, the opening widths of the figure pressing grooves range from 5 mm to 10 mm, the bottoms of the figure pressing grooves in the length direction are of an arc shape, an included angle between the two groove ledge surfaces in each figure pressing groove ranges from 80-85 degrees and the bottoms are smoothly connected by arcs with radii of 1.5-3.5 mm, and the largest depths of the bottoms of the figure pressing grooves range from 4-5 mm. According to the checkered plate roller and a using method thereof, the single engraved roller using times of the checkered plate special roller are increased and the roller consumption is reduced by optimizing the parameters of the figure pressing grooves of the checkered plate roller and the using technology of the roller.

Description

technical field [0001] The invention relates to the technical field of steel rolling, in particular to a roll for rolling checkered plates and a use method thereof. Background technique [0002] The pattern plate with anti-slip function is rolled on a rolling mill by a roll with pattern embossing groove. The commonly used patterns on checkered plates are lentil-shaped patterns, and the traditional lentil-shaped checkered plate rolls are prone to the following problems in use: the pattern grooves of the lentil-shaped checkered plate rolls are prone to chipping or cracks during rolling; The bean engraving depth is relatively shallow during the bean making process, resulting in a small number of times for a single engraving roller and high roller consumption. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a checkered plate roll and its use method. By optimizing the parameters of the checkered plate groove of the c...
