Cheltenham Induction Heating Ltd have developed a range of equipments for use in inline bright annealing applications.
The system shown produces bright annealed tube at a rate of approximately 6 metres per minute.This equipment is used for the inline bright annealing of stainless steel tube.The tube is heated in a controlled, reducing atmosphere and is cooled to ambient temperature within the length of the equipment.

Copper Pins for Plugs and Connectors
|
With the increasing trend towards crimped terminations in connections, there is an increasing need to bright anneal the area to be crimped whilst leaving the mating part of the pin in a relatively hard state. In order to achieve this differential in hardness, it is necessary to obtain a differential temperature and this needs to be rapid so as to prevent total heating and softening of the whole pin by conduction.
|
Typical production rates are in the order of 10,000 per day. Pin diameters from 1mm. Hardness of annealed zone is only limited by material specification and pin geometry.

Cheltenham Induction Heating Ltd have a range of induction heaters that allow the annealing of selected areas of copper and brass pins.

These photographs show a post weld annealing process being carried out on the construction site of an electric power generating station.The left hand photograph shows in the foreground the mobile temperature monitoring and control equipment with the induction heater in the background.The right hand photograph shows a steel tube with a flexible work coil wrapped around a ceramic blanket that covers the weld area. The use of a flexible work coil allows a variety of pipe sizes and configurations to be catered for.

The blade in this photograph is manufactured from a hardened steel.
Part of the manufacturing process calls for the end sections to be annealed. With induction heating, this can be carried out as an inline process that requires very little floor space.
