Abstract
An installation for diffusion saturation and heat treatment of wire by electrocontact cyclic heating is proposed. The equipment allows processing by continuous and stepwise wire feeding. The installation allows processing with a pulse duration and a pause duration of 0,01 seconds – 999 minutes. Allows you to set the current strength at a maximum value of 100 A and select the voltage value from the range of 3–32 V. The speed of movement of the wire in the processing area in the basic version is 10 cm/min. The influence of the fractional composition of the saturating medium on the course of the diffusion saturation of the wire has been studied. It is recommended to use a saturating medium with a particle size of 63–160 microns for borating steel wire. A method is proposed for optimizing the modes of diffusion saturation and heat treatment of wire when changing the diameter of the wire, the chemical composition of the wire material and the saturating medium, and the processing time.
