Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as figure 1 As shown, the roll assembly embodiment of rolling forklift mast section steel of the present invention includes a first roll 1 and a second roll 2 corresponding to the first roll 1, and the first roll 1 is provided with a first rolling groove 11. The second roll 2 is provided with a second rolling groove 21, the first rolling groove 11 and the second rolling groove 21 correspond and are formed after assembly figure 1 Pass 33 for the rolled forklift mast section shown. On the first roll 1, there are two first rolling grooves 11. The first rolling grooves 11 are arranged along the length direction of the first roll 11 , and a first transitional rolling groove 12 is arranged between the two first rolling grooves 11 . On the second roll 2 , there are two second rolling grooves 21 , the second rolling grooves 21 ...

The invention provides a mill roll assembly, a rolling mill and a method for rolling forklift portal frame profile steel. The mill roll assembly comprises a first mill roll and a second mill roll corresponding to the first mill roll. First roll grooves are formed in the first mill roll, second roll grooves are formed in the second mill roll, and the first roll grooves and the second roll grooves correspondingly form hole patterns for rolling the forklift portal frame profile steel. At least two first roll grooves are formed in the first mill roll and are arranged in the length direction of the first mill roll, and first transition roll grooves are arranged between every two adjacent first roll grooves. At least two second roll grooves are formed in the second mill roll and are arranged in the length direction of the second mill roll, and second transition roll grooves are arranged between every two adjacent second roll grooves. The first transition roll grooves and the second transition roll grooves correspondingly form transition hole patterns. The mill roll assembly can remarkably improve steel production yield of figured steel per hour, and reduces the production cost.
Description
technical field [0001] The invention relates to the technical field of special-shaped steel rolling in section steel rolling, in particular to a roll assembly, a rolling mill and a method for rolling forklift mast section steel. Background technique [0002] Sectional steel is a bar-shaped steel with a certain cross-sectional shape and size, which is indispensable in production and life. According to the quality of steel smelting, section steel is divided into ordinary section steel and high-quality section steel. Ordinary section steel is divided into large section steel, medium section steel and small section steel according to the current metal product catalogue. Ordinary section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its cross-sectional shape. For example, a small H-beam production line equipment mainly produces small H-beams of H100*100-H150*150 specifications. [0003] At present, some small section steel pro...
