SIKZ 160/12 Mid-frequency Induction Hardening System
2.2.2015
This system for mid-frequency induction hardening was designed in cooperation with the company Martenzit Ltd.. Hardening equipment SIKZ 160/12 consists of hardening machine SP-01, Transistor frequency converter, three-phase transformer, water cooling system VH-01-2S and inductors. The element which is to be hardened is clamped between tips. Due to this position it can rotate in pre-set speed. The hardening itself is implemented by means of program-controlled vertical movement of the inductor including MF transformer along the element at a defined speed.
The SP-01 hardening system - construction is based on experience in tried and tested concepts of vertical traverse hardening. In it's basic form, the equipment can be used for traverse hardening of non-rotating parts.
Transistor frequency converter - it ensures the transition of electrical current of grid-based frequency to the frequency needed for induction hardening. It is a modern semi-conductor based mid-frequency converter with a power output rating of 160kW and a working frequency of 12kHz. The converter is installed into a double-cabinet (main power/control power) that is mechanically attached to a single shared frame. The supply is equipped with direct-current monitoring of voltage and current in the mid-circuit, and frequency of the mid-frequency current.
The VH-01-2S system - contained water-cooling system VH-01-2S is an automatic cooling equipment consisting of cooling distribution and cooling for the induction hardening system water system cooling distribution. The primary water-cooling circuit is attachable to customer´s cooling system. To separate secondary circuit are designed the lower temperatures of the electronics and the actual hardened product. This system is equipped with monitoring of pressure, temperature, levels, and flow in all of its circuits and is controlled by an advanced PLC-based system.
A necessary part of the entire hardening system is the electronic control system, which ensures automatic and manual functions of the equipment and its stability. The control system allows for a high level of variability in the technological process due to the options available based on the hardening program. The hardening program is openly definable.
