Abstract

PURPOSE:To prevent deterioration due to cooling by means of a winding shaft having temperature lower than windable high temperature, by detecting the surface temperature of winding shaft and alarming upon exceeding over the windable high temperature. CONSTITUTION:In order to enable winding of high temperature band steel, winding shaft 1 where an adiabatic layer is applied on a segment is employed. A temperature detector 3 for detecting the surface temperature TM and alarming when said temperature TM has exceeded over the windable high temperature is provided on the winding shaft 1. The temperature detector 3 is comprised of a temperature detector 4 for measuring the surface temperature TM of the winding shaft 1, a setter 5 for setting the windable high temperature TR, an arithmetic unit 6 for performing the operation TM-TR and an alarm 7 for producing an alarm when TM-TR>=0. Consequently, deterioration of band steel due to cooling by the winding shaft 1 under the state where high temperature winding is not possible is prevented.

It is required to wind the film at a temperature of 750°C or higher, which is higher than 650°C. However, in conventional down coilers, which are strip steel winding devices, the winding temperature cannot be controlled other than by restricting or stopping the cooling water to each device in the down coiler. Take-up shaft (
Since the mandrel shaft (mandrel shaft) is at a low temperature, when the strip is wound as a coil on the winding shaft, several turns (5 to 6 @) on the side that contacts the winding cap are heated by the winding shaft. If it cools down, this part will no longer be a finished product.
