Abstract

The invention relates to an ultrasonic treatment production method for a cold-drawn pipe. The ultrasonic treatment production method for the cold-drawn pipe comprises the step of blooming, the step of cold drawing and the step of heat treatment. The step of ultrasonic vibration treatment is additionally executed after the step of heat treatment, the step of pickling and the step of finishing are executed after the step of ultrasonic vibration treatment. The ultrasonic parameter is 35-150 kHz. By the adoption of the ultrasonic treatment production method for the cold-drawn pipe, the technical effects of better eliminating the stress of the cold-drawn pipe, avoiding cracks of products, increasing the qualified rate of finished products and greatly increasing the yield and length of cold-drawn pipes are achieved. Through ultrasonic vibration, the stress problem of the cold-drawn pipe can be solved, a primary cleaning function can also be achieved, the time of the subsequent step of pickling can be greatly shortened, the intensity of the subsequent step of pickling can be greatly relieved, and the environmental pollution and the production cost can be reduced easily; in addition, an ultrasonic wave pool can be recycled, continuity and automation of production are achieved, and the ultrasonic treatment production method has extremely high industrial popularization value and practical value.

Description

technical field [0001] The invention relates to the field of metal manufacturing, in particular to the field of stainless steel manufacturing, in particular to an ultrasonic treatment production method for cold-drawn pipes. Background technique [0002] Cold-drawn pipe is a kind of steel pipe, that is, it is a kind of classification according to different production methods, which is different from hot-rolled (expanded) pipe. It is processed by multi-pass cold drawing in the process of expanding the diameter of the blank or raw material tube, usually on a 0.5-100T single-chain or double-chain cold drawing machine. The precision and surface quality of cold-drawn tubes are significantly better than hot-rolled (expanded) tubes, but due to process constraints, their caliber and length are limited to a certain extent. The characteristic of cold-drawn pipe production is that the pipe material usually undergoes multiple cold deformations and hardening after being processed into fi...
