Embodiment

[0058] Such as Figure 1-Figure 5 Shown in conjunction with, 1. of the present invention draws a kind of method that determines continuous rolling mill pass parameter with mechanical drawing, and its concrete steps are as follows:

[0059] The first step is to fill in the parameters and required parameters of the capillary tube and the blank tube after rolling into the pass parameter table according to the rolling table; such as: outer diameter, wall thickness, elongation, mandrel diameter, etc.

[0060] In the second step, fill in some parameters and regular relations of the pass design into the pass parameter table and calculate the corresponding parameters; the part parameters and regular relations are the elongation rate and the wall thickness of the bottom of the groove; the pass parameters of the pass are Height 2R, hole throat radius R1 of the pass parameter, eccentricity coefficient of the pass parameter, eccentric distance of the pass parameter; the first breakaway angl...

Abstract

The invention provides a method for determining hole pattern parameters of a continuous mill by mechanical drawing. The method comprises the following steps of: filling parameters of a pipe blank and a rolled pipe blank and required parameters in a hole pattern parameter list according to a pass schedule; filling partial hole pattern design parameters and a regular relation in the hole pattern parameter list and calculating corresponding parameters; drawing a hole pattern according to the data by using a mechanical drawing method; labeling and measuring the size and angle of the mechanically drawn hole pattern; obtaining data such as a center point coordinate of each hole pattern element and a steel tube deformation area according to the size and angle; filling the parameters in the hole pattern parameter list and calculating data such as elongation; and obtaining data of the hole pattern parameter list. The invention has the advantages that the design method is verified by given hole pattern parameters of a continuous mill imported from abroad, and the data are completely consistent. The invention has the advantage that a complicated algorithm and design steps are simplified by the technical scheme.

Description

technical field [0001] The invention relates to the field of continuous rolling of seamless steel pipes, in particular to a method for determining roll pass parameters of a continuous rolling mill by drawing mechanical drawings. Background technique [0002] Compared with other types of pipe rolling mills, the continuous pipe rolling mill has the advantages of a wide range of product specifications, good product quality, high output, low energy and tool consumption, and mature technology. It has been recognized by the steel pipe manufacturing industry all over the world. consensus. [0003] The continuous pipe rolling unit takes the continuous pipe mill as the core, and the determination of the pass series of the continuous pipe mill is closely related to the equipment selection of the main deformation process of the unit. The typical configuration of a modern continuous pipe rolling unit is "piercing machine + limiting mandrel continuous pipe rolling machine + pipe strippi...
