Modularized independent transmission rolling mill and unit thereof

Abstract

The invention discloses a modularized independent transmission rolling mill and a unit thereof, and belongs to the field of metallurgical rolling equipment. The modularized independent transmission rolling mill comprises a module rolling mill body, a gear box and a motor, wherein the rolling mill body comprises two mutually independent machine frames arranged in a box body; the gear box comprisestwo mutually independent gear trains; and the two machine frames on the module rolling mill body are connected with two mutually independent motor bodies through the two gear trains on the gear box. The unit comprises one or more modular independent transmission rolling mills, wherein each machine frame of the single or multiple module rolling mill bodies is capable of adjusting an extension coefficient between the machine frames based on the speed change of the corresponding motor bodies. The modularized independent transmission rolling mill can solve the problems that the speed ratio betweenthe two machine frames in a single module rolling mill cannot be flexibly adjusted, and solves the problems that the equipment structure is complex and the dead-load power consumption is high and thelike in the prior art.

Description

technical field [0001] The invention belongs to the technical field of metallurgical rolling equipment, and in particular relates to a modular independent transmission rolling mill and its unit. Background technique [0002] In the modern wire rod production, the equipment commonly used at present is the high-speed wire rod finishing mill, through the high-speed rolling of the wire rod finishing mill, the products that meet the size requirements can be obtained, and the output of the wire rod can be guaranteed. For small-sized wire rod products, in order to ensure the wire rod output, the rolling speed is even as high as about 110m / s. In the early days, due to the dynamic speed drop of steel bite in the high-speed rolling process of wire rods, it could not be solved, so the wire rod finishing mills currently used are all centralized transmission, that is, 8 to 10 wire rod finishing mills are simultaneously driven by a large motor to achieve a top crossing of 45° In twist-fr...
