lazyherbert   10 #2 Posted December 26, 2007 Any Iron and Steel workers out there know what a ' Bolter Down in a Rolling Mill ' is or was? Can you let me know please.  The term was Belter down.He is the man who receives the billet from the furnace,maybe a 3" billet .He then passes it through the rolls until it is maybe 7/8" or 3/4".He then passes it on to the next set of rolls where they will reduce it further.the process goe`s on until they obtain the required size & section.

Appolo   10 #3 Posted December 26, 2007 Any Iron and Steel workers out there know what a ' Bolter Down in a Rolling Mill ' is or was? Can you let me know please.   I worked in the rolling mills for 20 years as near as.  Starting from The Furnace Man he used to load up the cold billets into the furnace,& when they had reached their heat he would get them out with tongues & trail them to the rolls  then there would be the Cog Backers & the Prial backers who would pass the hot billets through smaller & smaller rolls till they were at their required size,they were supported by the Hookmen who took the weight of the heavy hot billets there would be an Under Roller & the main man The Roller usually at the end rolls making sure the finished aticle was the correct size.  Then there would be a Trailer Down who would run the finished steel to the Shearman if it was a square or oval finish or the Sawmen if it was round finish then to the hot Reelers where the Reelermen would pass the round bars through the cold rollers to ensure perfect straightness & circumference.  The bar s would then be stacked & allowed to cool before being bundled by the Slingers & then being hoisted away by the Craneman either on to a lorry or held in stock.  Every Mill had their different working titles for their workforce, this 1 was my old Mill & it's job titles.

Floridablade   11 #4 Posted December 27, 2007 I worked as a plate lad which is the final operation and then I was on the furnace. The first set of rollers were the cogbackers, the billet went into the bottom of 3 rollers then back through the top of the 3 until they were of a certain size then onto the next set until finally onto the plate to cool. The plate lad had to grab hold of the steel strip with a pair of tongues and then walk fast as the finishing rollers discharged it. We looked like miners because the works were filled with filthy black dust all the time. Share this post Link to post Share on other sites Share this content via...

lazyherbert   10 #8 Posted December 27, 2007 To my understanding a billet is rolled from a bloom.A bloom could weigh 2 ton & the it is rolled down to 2-3 Or 4 inch billet size then cut into required lengths. Share this post Link to post Share on other sites Share this content via...

Grandad.Malky   11 #11 Posted December 27, 2007 Thanks Herbert and Malky, greatly appreciated.  No problem, I worked at a mill and never heard of the job you described but different mills could use different terms, basically you start with a ingot, a bloom is a intermediate stage and you end up with a billet.
