Steam Hammer in Continuous Casting of Steel

Continuous casting of steel is the process where molten steel is solidified into a semi-finished billet, bloom, or slab for subsequent rolling in the finishing mills. Effective water cooling of continuous casting rolls is critical. Any drop in water pressure, even from a leaking hose, can result in reduced water flow causing water to remain in the rolls longer than recommended.

Steam, Paper Drying, and the Bottom Line

Because energy drives the papermaking process, steam is found in many energy streams in a paper mill. Steam is used to cook fibers for improved sheet strength, heat stock for improved drainage, heat process air for ventilation, heat dryers to dry paper, and selectively heat the web for improved gloss and smoothness.
