Abstract

The invention discloses a calculation method for checking and calculating the rolling force of high-speed hot-rolled wire rods. The method includes: 1) calculating the basic parameters; 2) calculating the temperature of the rolled piece; 3) calculating the rolling force parameters; the present invention combines the existing theoretical calculation formulas and empirical formulas, and proposes a set of simple and effective parameters through parameter correction. The calculation method of rolling energy can fully meet the needs of checking the rolling energy parameters of ordinary hot-rolled bar production lines, and can provide reference for design planning.

Description

technical field [0001] The invention relates to the field of production of hot-rolled high-speed wire rods, in particular to a calculation method for checking and calculating the rolling force of hot-rolled smooth-faced wire rods and hot-rolled threaded coils. [0002] technical background [0003] At present, the development of high-speed wire rod production technology is mainly aimed at increasing the hourly output of the rolling mill, the combination of no-twist / micro-tension, and improving the dimensional accuracy, surface quality, and structural properties of the product. The rolling mill for high-speed wire rods is mainly composed of a roughing mill, an intermediate rolling mill, a pre-finishing mill, a finishing mill and a reducing and sizing mill, which can produce coils with a minimum diameter of Φ4.5mm. [0004] In the early stage of design planning or transformation of high-speed wire rod production line, it is necessary to check and calculate the rolling capacity ...

AI Technical Summary

Problems solved by technology

However, due to the high rolling speed of the high-speed line, the final rolling speed can reach more than 100m / s, and the pure theoretical formula or empirical method cannot meet the rolling force parameters of the multi-stand and multi-hole continuous rolling process.
