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.

Embodiment 1

[0107] Take the production of Φ4.5mm hot-rolled smooth wire in a high-speed wire factory as an example for calculation. The plant has a total of 6 roughing mills, 6 intermediate rolling mills, 6 (5+1) pre-finishing mills, 10 (2+2+2+2+2) double-module rolling mills and 4 (1+1+2 ) minus sizing machine. The calculation process is shown in the following three tables, where the red numbers are known data. From the calculation results of rolling mill force and energy in Table 3, it can be seen that the rolling mill and motor power equipped in this factory can completely meet the production of Φ4.5mm hot-rolled smooth wire rod.

Abstract

The invention discloses a method for checking and calculating the rolling force energy of a high-speed hot-rolled wire. The method comprises the following steps of 1) calculating basic parameters; 2)calculating the temperature of the rolled piece; and 3) calculating rolling force energy parameters. According to the method, an existing theoretical calculation formula and empirical formula are usedin combination, a set of simple, convenient and effective rolling force energy calculation method is provided through parameter modification, a calculation result of the method completely meets the requirement for checking the rolling force energy parameters of a common hot-rolled bar production line, and reference can be provided for design planning.

Description

technical field [0001] The invention relates to the field of high-speed hot-rolled wire rod production, in particular to a rolling force energy check calculation method for hot-rolled smooth wire rod and hot-rolled threaded coil. [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 rod is mainly composed of roughing mill, intermediate rolling mill, pre-finishing mill, finishing mill and 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 of the rolling mill of the production line ...
