Man of Steel… products

From Joel, MSE Senior

Time has flown and there are only 6 weeks left till classes start again!

Joel at the Charter Steel shipping yard

This summer I have been interning at Charter Steel in Cuyahoga Heights, Ohio (of Charter Manufacturing) which produces round bar, rod, and wire steel products.   Sizes range from 7/32 up to 1-9/16 inches and almost all common grades of steel are produced.

I work with the Quality and Technical Manager for the rolling mill. The two major projects I work on involve improving the yield of product as it rolls through the mill, and organizing and consolidating the cooling practices that the steel undergoes. These projects will reduce downtime for the company, and increase revenue of the final product.

Making the Slinky

We melt scrap with an Electric Arc Furnace (EAF) and strand-cast ~34-foot long billets that are 7×7 inches in cross-section. The billets are reheated in the rolling mill (where I work) and then rolled down from square cross-section to their final diameter.  A series of consecutive rolls (31 intotal) reduce the billet size. One 34-foot billet can produce up to 4-5 miles of steel rod. One billet weighs about 2.5 tons and is wrapped at the end of the rolling mill, much like a slinky.  One ring overlaps the next, which overlaps the next. The “coil” of rings is wrapped into a tight package which is then shipped to customers via truck or train. Common product uses include roller bearings, springs, welding wire, fasteners/bolts, and rebar for concrete.

 

Freshly-made Coil

Charter Steel ordered a set of uniforms and steel-toed boots for me so that I fit in with the hourly crews. I often get free lunch and I have taken a few business trips to customers’ facilities. It is a very laid back atmosphere at Charter, but everyone is a very hard worker when they need to be. There have been a few times throughout the summer where I actually had to pull out my old MSE 205 book to review some things with my boss.  It felt good to get some use out of my college knowledge.

Graduation looms at the end of fall quarter for me, but after this second internship, I feel better prepared for the real world. Now all I have to do is find a job….
