Avalloy

Company Description

The Company
Avalloy is involved in the production of high performance alloys that are produced to order and are used in a variety of different applications.

The main operating units of the Avalloy facility consist of a Vacuum Induction Melting (VIM) Furnace and a Vacuum Arc Remelting (VAR) Furnace.  The plant is equipped with the necessary laboratory facilities, infrastructure and services for the complete operation, quality assurance and presentation of product.

Capability:
The production process consists of two main processes.

Cast alloys
This is a Vacuum Induction Melting (VIM) process, whereby a recipe of metals is melted in a vacuum to ensure the removal of deleterious gases and metals, to produce cast stick in various sizes raging from 50 to 175mm and 450mm ingots.  The furnace is a 4-ton Leybold furnace.  It is supported by three smaller VIM furnaces that are suitable for special melts, process research and development programmes.

Wrought alloys
This is a process whereby an ingot is processed through a Vacuum Arc Remelting furnace (VAR).  This process ensures the further refinement and homogenization of the ingot.  The VAR is a twin-station, one megawatt furnace, capable of producing 450mm diameter ingots up to 2.0 tonnes each.  This VAR is supported by a 50kg VAR which will be used for research and development. The current installed capacity of the VIM plus VAR combination is approximately 4 000 tonnes of product per annum when operated on a three-shift basis.
