Finish rolling system for metal powder semi-solid primary rolling strip

Abstract

The invention provides a finish rolling system for a metal powder semi-solid primary rolling strip. The finish rolling system comprises a finish rolling unit and a shearing unit, the finish rolling unit comprises a finish rolling machine frame, a first roll system, a second roll system, a third roll system, a first roll gap adjusting device, a second roll gap adjusting device and a third roll gapadjusting device; the shearing unit comprises a shearing machine frame, an eccentric cam, a cam connecting rod, a reciprocating shearing knife and a liftable plate strip supporting plate; and the finish rolling machine frame comprises a first finish rolling machine frame and a second finish rolling machine frame. Three passes of post-treatment rolling can be carried out on a plate strip formed byprimary rolling of semi-solid metal powder slurry, and the width, the thickness and the length of the plate strip are not limited to one size.

Description

technical field [0001] The invention relates to the field of post-processing equipment for pre-rolled strips, in particular to a finish rolling system for metal powder semi-solid pre-rolled strips. Background technique [0002] Among various powder forming technologies, semi-solid powder rolling forming technology can prepare plates, strips, etc. that cannot be produced or are difficult to produce by other forming technologies; the process is short, energy-saving, and low-cost; the compact or product composition is precisely controllable , The rolled product is isotropic and has a high yield. Therefore, semi-solid powder rolling forming technology has become the most important technical means in continuous forming technology, and has been widely used in chemical industry, energy, transportation, environmental protection and other industries. The semi-solid powder rolling process is a process in which the semi-solid metal powder slurry enters between the rolls through the fe...

AI Technical Summary

Problems solved by technology

At present, the existing equipment for semi-solid metal powder rolling is still unable to fully adapt to this new forming technology by using the traditional rolling machine. The width, thickness and length direction of the plate and strip produced by complex equipment are often difficult to control. The disordered part of the strip does not meet the production requirements, and it needs to be trimmed in the later stage. The most important thing is that the density and mechanical properties cannot meet the higher requirements.
