The computer programs for wire drawing

There is a group of Pereng programs for computerized calculation of drafting, drawing force, temperature and power. It has been enlarged with a new variant - PerengR. In this version the need of power, force and torque is compared with the ability of the drawing machine, with its actual configuration, to meet this demand for the planned drawing. Per Enghag and Lars Rabe have prepared the new program type.

Machine data, installed power, nominal rpm, capstan diameters, efficiency and transmission are typed in, as is actual drafting. The program compares the performance of the drawing machine with what is needed for drawing of the actual wire rod with its tensile and deformation hardening. In a special table warnings are issued if the drawing is not possible to carry through with reference to force, power or torque. The temperature increase in each draft is calculated (estimated).

The program is a powerful tool for analysis of the complete park of drawing machines in the company. The result can be the base for steps to increase quality and reduce energy consumption.

For comparison between different alternatives at the formulation of a specification of requirements for a new machine installation the program calculations can be very helpful.
The version mainly deals with dry drawing but special tables and diagrams also open possibilities to make calculations for drafting of wet drawing machines with constant reduction. Also 1-3 dry drafts with variable reduction – before the wet drawing – can be calculated by the program. Two separate PerengR programs, one for carbon steel, one for austenitic stainless steel, are available.

Cost
The carbon steel program 310 Euro
The program for austenitic stainless steel 310 Euro
The two programs together on the same CD disk 500 Euro

The programs thus are delivered on a CD disk. The disk also contains general program information and many exercises for introduction and training.
A demo CD is delivered free of charge. The program application however presupposes that the user has installed Microsoft Excel in his own computer. Excel is a part of Microsoft Office.
