| Tawn Orock posted Warming things up on this 15 degree morning here in western pa. [The billets are 10 5/8" by 400" (33.3') long. According to several comments, those are big billets. They will be used to make seamless pipes.] Brad Parker: Blooms. Technically anything 6” or larger, regardless of shape, is considered a bloom. Steven M. Hnatiak: In the late 70's I worked at USS Steel Tubular Mill in Lorain, Ohio for 5 years. The Mill employed 8600 employees during this time. I worked at the East end of the mill (3 Seamless Hot end which made the biggest diameter,thickest wall, longest seamless tube). On the West end we had 2 blast furnaces and 1 BOP shop that made the molten steel which was poured into molds that where on narrow gauge railroad cars. The billets where placed into railroad cars and where transported to the East end of the mill to the 3 seamless mill. Overhead cranes with electric magnets would unload the billets onto racks that fed a circular rotary furnace. These billets were heated to 3000 degrees F. and taken out and placed on roller racks and fed inro a rolling mill (2 large rollers). This billet was forced into this mill and a tungsten plug with a water cooled pipe was locked into position. This created the beginning of the seamless tube(approx. 8 inch diameter X 60 inches long). (note: this mill was called the First Piercer). If the billet became to cold or the piercer water cooled pipe was not locked into place this pipe could bend like a pretzel and come out of its guide and come back to the steel shed that the operator was located.( There was a large RED EMERGENCY BUTTON that would stop the rolling mill). Will be continued....... |

| Tenaris-2021-Jun "Steel production is now underway at Tenaris’s first melt shop in the United States that will soon supply steel bars for its seamless pipe mills in the States and Canada. The steel shop in Koppel, PA, part of the company’s strategic acquisition of IPSCO, completed in 2020, has started producing steel bars following a year-long investment of more than $15M USD in upgrades to integrate the facility into Tenaris’ global network of steel mills....The investments included expansion of the mill’s capabilities to produce a wider range of steel bars. This work entailed new design and install of molds for the caster, where the liquid steel is solidified, and other structural reinforcements. Betterments also included an overhaul of the existing cranes in the mill as well as the addition of new cranes to transfer scrap metal to the furnaces, the integration of a new production management system and additional automation upgrades." |
This plant will feed bars to their Ambridge, PA, and Bay City, TX, mills that produce seamless pipes. [Tenaris-2021-Sep]

| Tenaris-2022-Feb and EllwoodCity "Tenaris is gearing up to reactivate its heat treatment and finishing lines at its Koppel, Pennsylvania, plant to streamline the flow of seamless product at its facilities in the northeast." The pipes are threaded and finished in Brookfield, OH. |
