Digital design method of high-speed wire rod roller

Abstract

The invention discloses a digital design method of a high-speed wire rod roller, which comprises the following steps of: calculating the diameter of a roller neck meeting the strength requirement through an initial fillet, and judging whether the obtained diameter of the roller neck meets the compact requirement or not according to the ratio of the diameter of the roller neck to the diameter of a roller body, so as to adjust a transition fillet and then carry out iterative calculation; through the steps of initial assignment, result judgment, iterative calculation and the like, the roller design method of the high-speed wire rod rolling mill is optimized, it is guaranteed that the mechanical property of a roller meets the high-speed rolling requirement on the premise that the diameter of a roller neck is not increased, and the high-speed rolling requirement is met on the premise that the equipment weight is not increased and the compactness of a production line is guaranteed. And the strength of the roller meets the requirement of continuous and stable production.

Description

technical field [0001] The invention relates to the technical field of production equipment in the metallurgical industry, in particular to a digital design method for high-speed wire rolls. Background technique [0002] Rods and wires are widely used in various industrial production and construction industries. After years of development, the rolling speed of high-speed wire has increased from 40-50 meters per second in the early days to more than 120 meters per second now. As the country with the largest wire rod production in the world, China has an annual wire rod production capacity of more than 80 million tons and has more than half of the world's rolling mills. Due to the late start of research on high-speed wire rod mills in my country, most of the high-speed wire rod mills still need to be imported from abroad, which leads to high purchase and production costs of corresponding materials. [0003] With the gradual increase in the proportion of high-end wire rods an...

AI Technical Summary

Problems solved by technology

By increasing the diameter of the roll neck, the maximum bending stress can be reduced and the strength of the roll can be improved, but at the same time, the size of the roll bearings, bearing housings, archways and other components will increase synchronously, resulting in increased equipment weight and uncompact equipment layout.
