Brown Bayley Steels

Brown Bayley Steels was a steel making company established in Sheffield,England in the 1871 , as Brown, Bayley & Dixon. They occupied a site on Leeds Road which is currently 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 Manufacture Bessemer steel and railway tracks. [A Photographic History of Sheffield Steel,by Geoffrey Howse, published by WH Smith, ISBN 0-7509-2856-5]

Notable among its employees was Harry Brearley, the inventor of stainless steel. Bearley left Firths after a dispute over the patents and was offered a position at Brown Bayley, were he was appointed works manager (Date ?) and then became a director.

The company occupied a 32 acre site.

The Melting shop

Scrap steel loaded by overhead cranes using electromagnetic grabs fed the Siemens Martin Open hearth furnaces via charging machines tipping “coffin” like 6ft long 18 inch wide loading containers directly into the furnaces. The furnaces were heated by water gas and producer gas made on site fed to the furnaces by 36” gas mains.

The molten metal had alloys added, then sampled and after satisfactory laboratory checks of the metal composition the furnaces were tapped out into preheated bottom pouring ladles holding some 20 tons. The ladles were manoeuvred by overhead crane into the casting bays over several ceramic runner systems each feeding six preheated 1-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.

After cooling and weathering selected ingots would be transported to the machine shop where they were placed on ingot planning machines to remove the outer-scaled 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.

No1 Mill

No1 Mill was a 30” reversing cogging mill driven by a several hundred horsepower electric motor through a Krupps gearbox. The cogging stand reduced the 12” square section ingot to either slab or bar of 9” section. All hot material was moved at ground level on live roller paths. The second and third stands reduced material to either square or round bar of 4” section, or plate of 2” section.

The first stand had a hydraulic manipulator, which turned the material for rolling and also aligned it with a hydraulic accumulator driven hot shear, which cut off the red-hot ingot runner head of 9” square section in 3 seconds. The manipulator then aligning the ingot with the reducing rolls making several passes to make the required section.

After rolling to the ordered section the red hot steel ran along ground level live roller paths to the hot saws or hot shears. The hot saws had a 4ft diameter carbon steel saw blade similar to a woodworkers circular saw but running with a constant cooling water spray to the teeth. These hot saws were capable of slicing through 4” bar in seconds with showers of sparks and the screaming metal emitting a noise of 110 decibels.

Hot Shears also cropped the bar to length but left indentations in the end of the bars where hot sawing left a straight clean cut. The bars were then lowered into cooling pits before being taken to heat treatment and bar straightening machines.

Round bar straightening was done in machines known then as “Reelers” with a convex and concave roller paired together at an angle, the action of which both straightened and fed the bar whilst passing it through the machine. Again the entry chute to the machine was a lidded box built to contain the flailing bent bars which emitted a very loud rattling noise.

pecial steels

Electric arc furnaces also produced steels using scrap from “T’Top Bank” many tons of armaments arrived at the Top Bank for melting down Oerlikon and other anti aircraft guns arriving by rail for destruction into steel for peaceful use.

Two High Frequency Electric Furnaces produced 1-ton melts of special steels in an area close to the main electric arc furnaces.

No, 6 Mill

No6 Mill was a three high rolling mill with several stands (Sets of Rolls) producing bar down to thick wire sizes from red hot billets taken from the reheat furnaces. The small diameter rod and bar produced in this mill snaked all over the cast iron floor plates. The operators used tongs to catch hold of the end of the red hot bar as it left the rolls, passed the bar around their body allowing it to loop out onto the floor and then entered the bar into the next pass position. In one hot summer the floor plates expanded, the expansion could not go anywhere and two plates buckled upwards like flagstones directing the hot metal into the air – within milliseconds there was no one on the mill floor as the metal reared up towards the roof and collapsed in a writhing heap as the mill rollers continued to spew out the rest of the bar.
