Abstract
The invention belongs to the technical field of metallurgy, and relates to a device for gradual horizontal-vertical conversion of hot-rolled flat steel. In order to solve the problem that the traditional flat steel can be erected only by transition of a cooling bed or a chain type transverse moving rack, the invention provides a device for gradual horizontal-vertical conversion of hot rolled flat steel, which realizes smooth conversion from a flat state to a vertical state of the flat steel at the outlet of a rolling mill. The core of the progressive horizontal-vertical conversion device for the hot rolled flat steel is that a horizontal-vertical conversion guide groove is adopted, the horizontal-vertical conversion guide groove consists of a guide groove retainer, a long roller and a short roller, a key groove with a progressive angle conversion is processed on the guide groove retainer, and the key groove is connected with a support through a key to realize the progressive conversion transition of the angle of the horizontal-vertical conversion device. The invention has the beneficial effects that: the novel production line has the advantages of small occupied area, light weight and high rhythm, can be applied to a newly designed production line, can also be applied to the existing production line on the premise of not influencing the production of the existing production line, and is favorable for product expansion.
Description
Technical Field
The invention belongs to the technical field of metallurgy, and relates to a device for gradual horizontal-vertical conversion of hot-rolled flat steel.
Background
After being rolled, the flat steel is in a flat state at the outlet of a rolling mill, and the common production process is that the steel is fed through a skirting roller way, cooled on a rack type cooling bed or a chain type marshalling rack and then enters a rear process.
For part of small bar production lines, due to the structural limitation of the apron roller ways, the flat steel cannot share one apron roller way with the small bars, and in order to realize the production of the flat steel, the flat steel at the rolling outlet needs to be transported to the position of the cooling bed output roller way through the arc-shaped guide groove. Due to the bending radius of the flat steel, in order to prevent the flat steel from generating unrecoverable plastic deformation, a set of gradual flat-vertical conversion device is needed, so that the flat steel at the outlet of the rolling mill is smoothly converted from a flat state to a vertical state, and the flat steel directly enters the rear process.
To some flange end plate production lines, present band steel manufacturing enterprise all is through skirtboard roll table down the steel after, get into the low level roll table and stand the band steel upright after carrying on the chain marshalling the rack, then get into the process of curling, this is the equipment structure of sideslip rack is complicated, the investment is high, in addition, the cooling of marshalling the rack influences the temperature of band steel, increase the degree of difficulty of rear portion process, through setting up one set of gradual formula tie and stand conversion equipment, cancel marshalling the rack isotructure, realize that rolling mill export band steel is by flat state to vertical state conversion smoothly, directly get into rear portion process.
Disclosure of Invention
The technical problem solved by the invention is as follows: the flat steel at the outlet of the rolling mill is smoothly converted from a flat state to a vertical state by using less occupied area and less investment equipment, and the flat steel directly enters a rear process.
The technical scheme adopted by the invention for solving the technical problem is as follows:
the progressive flat-vertical conversion device for the hot-rolled flat steel is positioned behind a finishing mill, flat steel at the outlet of the finishing mill can be directly and smoothly converted from a flat state to a vertical state, the erected flat steel can directly enter a rear process, and if the erected flat steel needs to be laid flat again, a section of reverse flat-vertical conversion device can be additionally arranged at the outlet.
The invention relates to a progressive horizontal-vertical conversion device for hot rolled flat steel, which consists of a connecting lug seat I, an inlet horn, a support, a base, a horizontal-vertical conversion guide groove, a connecting lug seat II, an outlet horn and keys. The core is that a horizontal-vertical conversion guide groove is adopted, the horizontal-vertical conversion guide groove is composed of a guide groove retainer, a long roller and a short roller, and the long roller and the short roller are connected with the guide groove retainer through bolts. The guide groove retainer is provided with key grooves with different angles, the support is provided with key grooves with the same angle, and the guide groove retainer is connected with the support through keys to realize gradual conversion transition of the angle of the horizontal and vertical conversion guide groove, so that the flat steel entering the guide groove is gradually converted from a flat state to a vertical state. The conversion angle of each key slot can vary according to the requirements of different production line product outlines, and the conversion angle of each guide slot is generally 1.5-4.5 degrees.
The invention has the beneficial effects that: the novel production line has the advantages of small occupied area, light weight and high rhythm, can be applied to a newly designed production line, can also be applied to the existing production line on the premise of not influencing the existing production line, and is favorable for product expansion. The invention can also be used for the production line of the end plate, eliminates a complex steel discharging system such as a marshalling rack and the like, reduces the temperature drop and smoothly realizes the full-automatic production of the end plate.
