Title: Determining solid skin thickness on cast steel billets - using temp measurements in direct cooling zone
Inventor: MATZNER HARTWIG DIPL ING
IPC: B22D11/20
Filed: 1974-04-10
Abstract: A process for monitoring the thickness of the solidified skin in a continuously-cast steel billet underneath the mould in the direct cooling zone in which the alteration of the surface temp. of the billet w.r.t. time is measured in a defined zone and the reheating speed is used as a measure of the thickness of the solidified skin. The pref. method consists of strongly cooling a defined zone and then measuring the temp. rise after the cooling ceases using two preselected points sepd. by 30-100 mm depending upon the billet speed, the distance of 30 mm being used for low billet speeds of about 1 m/minute. Process detects the existence of a very thin solidified skin. If a very thin skin is present, the molten core can burst through the skin; this monitoring process is designed to prevent such mishaps.
