Fine-grain strengthening and enhancing device for surface of steel tube tower component

Abstract

The invention provides a surface fine-grain strengthening device for a steel pipe tower member, which includes a conveying support, and the workpiece moves along the conveying support through rollers; a fine-grain treatment chamber surrounding the workpiece is arranged on the movement route of the workpiece, and the fine-grain treatment chamber is installed There are several grain refiners distributed around the work. A group of six fine-grain processors are distributed equidistantly along the outer circumference of the workpiece. The present invention designs a special equipment, adopts high-speed throwing or high-speed spraying method to make the fine-grained particles hit the surface of the component at high speed, so that the crystal grains on the metal surface of the component are refined and dense, and the superficial strength of the component metal is improved, so that the steel pipe tower can be improved. The purpose of overall strength. Taking into account the improvement of strength without affecting the elongation and yield strength; it can increase the overall workpiece strength by 5‑10%, and the overall resource efficiency can be increased by more than 20%.

Description

technical field [0001] The invention relates to the field of surface treatment devices for semi-finished steel pipe tower components, in particular to a surface fine-grain strengthening device for steel pipe tower components. Background technique [0002] The existing process generally adopts welding and grinding of semi-finished products, followed by subsequent hot-dip galvanizing treatment, etc., which will reduce the elongation and yield strength, which is not conducive to subsequent processing and production. The strength index of the component is completely determined by the performance of the steel plate itself. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a surface fine-grain strengthening device for steel pipe tower components, and a special equipment is designed to use high-speed throwing or high-speed spraying methods to make fine-grained particles hit the surface of the component at high speed,...
