Description of Project

Arcelor Mittal is in the process of converting the molds on the continuous caster CCM #1 located at the 3SP.  Once complete the caster will be able to cast 9 1/4” thick slabs versus the 10” thick slabs it presently casts. Before the caster can be upgraded, corroded structural  steel and piping needs to be addressed. One portion of the conversion is upgrading the piping inside the spray chambers of the vertical, unbending, and horizontal sections of the CCM#1, where much of the piping has corroded due being carbon steel in a hot wet environment, and now leaks, or is prone to future leaks.

 Scope of work

HOH inspected the piping that travels into the CCM #1 spray chamber. Some piping had been converted from the original carbon steel to stainless steel; HOH is identifying which piping still had not been converted to stainless steel,. HOH is preparing construction packages including piping isometrics, and mark-ups of drawings and photos for identification, and a line list in order to identify which piping modifications will be made during which mini-outages (~14 hours each),

Value to client

Three modified caster will produce a slab that has more applications than the present 10” thick slab and open additional markets for sale. The upgrade to stainless piping will eliminate current leaks, as well as prevent future leaks for many years to come, reducing energy and water waste. HOH by preparing the design and details to be installed in 14 hour mini outages enables the caster to maximize production and limit down time.
