Abstract
Toward the end of 1987, a moderincation program was completed at Stelco's Hilton Works in Hamilton, Ontario. Two large slab casting machines, with a combined annual capacity of approximately 2 million tons, were built at a cost of C$270 million. One slab and one combination slab/jumbo bloom machine were sized to cast about 70% of the capactiy of the existing three-vessel BOF shop.
One of the features of this modern casting facility was the inclusiong of a Metallurgical Testing Laoratory immediately adjacent to the cross-cutting station in the caster runout table area. This facility included everything needed to quickly produce a sulphur print and/or a macrotech.
This paper describes the Stelco-developed apparatus, the "Electrolytic Macroetcher", which makes it possible to produce a macheretch under production conditions without endangering the operator or contaminating the environment.
