WebOct 1, 1998 · A four-vane subsonic cascade was used to investigate the influence of film injection on vane heat transfer distributions in the presence of high turbulence. The influence of high turbulence on vane film cooling effectiveness and boundary layer development was also examined in part II of this paper. A high-level, large-scale inlet … WebImplementation of a position controlled HTRC system provided effective roll cooling using a low pressure water supply (3-4 bars), without compromising roll and strip surface quality.
Webroll cooling using a high turbulent flow regime. HTRC is positioned very close to the roll surface and gap exit, which is beneficial for the roll surface quality. It is operated at a high … WebDec 4, 2007 · The objective of this pilot and demonstration project was the implementation of high turbulence work roll cooling (HTRC) in the early stands of a hot strip finishing mill. The project consisted of three main tasks: the analysis of small reference high turbulence cooling headers; the characterisation of an industrial prototype on the full-scale work roll …
WebThis earlier version of the HTRC system has been in use in the ArcelorMittal Gent Finishing Mill since 2006. The objectives of high turbulence cooling are to increase the overall cooling... WebJun 27, 2024 · Each process has to be treated a little differently, but with the same goal—to achieve turbulence at the heat-exchange surface to maximize heat transfer. For example, in a chill roll for sheet/cast film, cooling turbulence is created in the spiral wraps to cool the shell. For blow molds, turbulence is generated in the water passages of the mold.
WebHTRC is a relatively novel way of roll cooling, developed by CRM, using a high turbulent flow regime, operated at a high flow rate (up to 700 m3hr per HTRC unit) and at a low pressure …
