A method and system for controlling feed in rolling process of ring rolling mill

Abstract

The invention discloses a ring rolling mill rolling process feeding control method. The method comprises the steps that the section width and the height of a ring piece blank are measured in real time; according to the real-time section width of the ring piece blank, axial rolling force is adjusted according to the function relation obtained in advance between the section width and the height of the ring piece blank, so that the height and the section width of the ring piece blank conform to the function relation between the section width and the height. By the application of the ring rollingmill rolling process feeding control method, the feeding amount can be controlled precisely, the problems of response lag and the like generated by observation of a manipulator are avoided, the product quality is improved remarkably, the size stability of products is improved, and the appearance is more structured. The invention further discloses a ring rolling mill rolling process feeding controlsystem which has the above technical effects as well.

Description

technical field [0001] The invention relates to the technical field of rolling, and more specifically, relates to a method for controlling feed in the rolling process of a ring rolling mill, and also relates to a feed control system in the rolling process of a ring rolling mill. Background technique [0002] Ring products are widely used in machinery, automobiles, trains, ships, petrochemicals, aviation, aerospace, atomic energy, wind power and many other industrial fields. The material of the ring is usually carbon steel, alloy steel, stainless steel, titanium alloy, copper alloy, aluminum alloy, cobalt alloy, nickel-based alloy, superalloy, etc. Production of various shapes and sizes of ring machinery parts such as bearing rings, ring gears, flanges, hubs, thin-walled cylindrical parts, wind power flanges, high-neck flanges, etc. . When the ring is rolled, it is necessary to use a ring rolling machine to cause continuous local plastic deformation of the ring, thereby ach...
