Melting Shop

The photo shows part of the Goodwin melt shop and shows molten steel being transferred into a vessel, for transfer to the AOD refining vessel.

Goodwin are able to raise a total of 18,000kg for a single pour. Steel and nickel alloys are electric melted and can be processed through the AOD refining vessel.

Transferring metal to the AOD vessel

Molten steel being transferred to the AOD (argon-oxygen decarburisation) refining vessel for treatment.

The use of the AOD enables removal of volatile elements and the reduction of inclusions and impurities in the steel. Close composition control and the addition of nitrogen is also possible.

Goodwin £500,000 heat treatment centre

With a remarkable 'furnace to quench time of less than 30 seconds for a 10-ton load, the installation was specifically designed for optimised quenching of duplex stainless steel and super nickel alloys.

It is capable of operating at 1,300°C with precise temperature control. All Goodwin heat treatment furnaces are controlled and monitored by a networked data-logging management system, ensuring traceability and control.

Pattern facilities

Goodwin has its own in-house pattern shop which is manned by highly skilled pattern makers. When the need arises patterns can be produced by local master pattern makers.

The senior methods engineer and foundry dimension inspector are time-served pattern makers, ensuring that patterns are produced that will give the required casting.

Blasting

Large 2-ton structural castings undergoing shot-blasting to remove sand and scale prior to inspection.

As well as two large cabinet shot blasts for sand and scale removal Goodwin have a blast room for hand blasting internal passages and processing castings requiring architecturally pleasing surfaces.
