Brown Bayley Steels
Brown Bayley Steels was a steel-making company established in Sheffield, England in 1871, as Brown, Bayley & Dixon. They occupied a site on Leeds Road which was later occupied by the Don Valley sports stadium. The firm was founded by George Brown, nephew of John Brown of the firm John Brown & Company. The firm manufactured Bessemer steel and railway tracks.
Notable among its employees was Harry Brearley, the inventor of stainless steel. Brearley left Firths after a dispute over the patents and was offered a position at Brown Bayley, where he was appointed works manager and then became a director.
The company occupied a 32-acre (130,000 m2) site.

Scrap steel, loaded by overhead cranes using electromagnetic grabs into containers. These were fed into the Siemens Martin Open hearth furnaces via charging machines which tipped the “coffin-like" 6-foot-long (1.8 m) 18-inch-wide (460 mm) loading containers directly into the furnaces. The furnaces were heated by water gas and coal gas made on site, and fed to the furnaces by 36-inch (910 mm) gas mains.
The molten steel had alloying metals added; after sampling and satisfactory laboratory confirmation of the molten metal's composition the furnaces were tapped out into preheated bottom-pouring ladles, which held some 20 tons of steel each. The ladles were manoeuvred by an overhead crane into the casting bays where they were poured over several ceramic runner systems, which each fed six preheated one-ton ingot moulds. After cooling, the ingot moulds were stripped of the still hot ingots and taken to the ingot yard. In the 1950s, the transport from the Open Hearth Casting Bays to the ingot yard was by steam lorry, or on the internal steam railway system. As of 2016, a fully restored original example of one of the steam lorries carrying the Brown Bayley livery can be found at the Riverside Museum in Glasgow.
After cooling and weathering selected ingots would be transported to the machine shop where they were placed on ingot planing machines to remove the scaled outer surface and allow examination for cracks and impurities. Impurities were gouged out with chisels using pneumatic “chipping hammers” or by manually operated swing frame grinding.
Electromagnets carried ingots to the skid pusher behind the reheat furnaces of No.1 Mill. These furnaces were again heated by on site-produced raw coal gas.
