Problems solved by technology
However, in the edge trimming process of the above-mentioned hot strip slitting process, since the edge material and the main body of the plate are in a high temperature state (generally between 700°C and 900°C), the shear shape of the edge material is distorted and has strong plasticity. It is not possible to use the guiding method of cold steel plates for subsequent processing, that is, it is not possible to use the treatment method of cutting edge materials after cold steel plates are cut
If the hot steel is guided passively in the cold state, it is prone to steel blocking accidents

Embodiment
[0034] Such as Figure 1 to Figure 2 As shown in this example, a hot strip after slitting device includes a tension roller group 4, a feeding roller group 5, and a breaker 6, which are arranged in sequence according to the feeding direction of the side material 2. The clamping and guiding mechanism 3 for actively pulling the edge material 2.
[0035] Among them, the strip is supported by rollers 8 and conveyed; the crusher 6 is used to cut off the edge material 2; the feeding roller group 5 is arranged upstream of the crusher 6 to receive the edge material 2 from the upstream, and The side material 2 is fed to the breaker 6, the feeding roller group 5 is always closed, rotating, and the fed side material 2 is clamped, the rotation speed matches the hot slitting speed; the tension roller group 4 is set in the feeding roller group 5 Upstream, used to keep the tension between the edge material 2 and the uncut mother board 1.
[0036] Among them, the clamping and guiding mechanism 3 ...

The invention provides a rim charge crushing device and method after hot state plate strip slitting. The device comprises a tension roller set, a feeding roller set, a crusher and clamping guide mechanisms, wherein the crusher is used for cutting off rim charges; the tension roller set is arranged at the upstream of the feeding roller set and used for tensioning the rim charges and an uncut motherboard; the feeding roller set is arranged at the upstream of the crusher and used for receiving the rim charges and feeding the rim charges to the crusher; and the clamping guide mechanisms are usedfor clamping the slit rim charges, drawing the rim charges to penetrate through a roller gap of the tension roller set and feeding the rim charges into the feeding roller set. According to the rim charge cutting device and method after hot state plate strip slitting, by adopting an active traction mode, the rim charges are forced to advance according to a designed route, the shape influence of therim charges is avoided, the characteristics of hot state rim charge distortion and strong plasticity can be adapted, the rim charges can smoothly enter the feeding roller set and the crusher, the occurrence of steel blocking accidents is avoided, and safety and reliability are realized.
Description
Technical field [0001] The invention belongs to the technical field of rolling in the molten steel metallurgical industry, and specifically relates to an edge crushing device and an edge crushing method after longitudinal cutting of a hot strip. Background technique [0002] It is a new process and new technology to use the waste heat after rolling to perform hot slitting and slitting of the high temperature steel plate after rolling. It is characterized by high production efficiency and can realize seamless connection with subsequent hot bending units. For example, a hot roll bending and slitting process for hot strips disclosed by the Chinese invention CN201910236727.2. After the high-temperature steel plate or strip is processed by centering, pinching, striping, separating, and crushing, the main part of the strip is rolled The strips are divided into a number of roll-bent steel parts with the required width, and the auxiliary waste part is collected into the basket after the...
