I was aware that Mesta and Blaw-Knox made equipment for steel mills. Mackintosh-Hemphill was another supplier of big equipment. I should have been aware of the company because I have notes about the headquarters plant in Pittsburgh.

| David Holoweiko posted Mackintosh-Hemphill company Midland PA R Jim Echlin: Worked at Blaw Knox in East Chicago, IN from 1964 through 1986. Made literally hundreds of rolls using molding methods similar to what is shown in the picture. This is a split mold and probably would be used in the production of a roll with grooves (passes) such as a structural or blooming mill roll. |
"Pittsburgh Iron and Steel Co. -- which had purchased the St. Jarvis-Adams foundries operation -- was also running multiple open-hearth furnaces, which were relied on to churn out the millions of ordinances needed by the U.S. military during World War I....Mackintosh-Hemphill purchased Pittsburgh Iron and Steel in 1922."
