IPC: C21D9/573
Filed: 1990-10-26
Abstract: PURPOSE:To cool entire surface uniformly and effectively by blowing an inert gas cooled to a specified temperature radially, helically or spirally at an outer surface of a wire in high temperature immediately after drawing the wire. CONSTITUTION:Before a protection film coat is applied on the outer surface of a high temperature wire 5 which is just formed by drawing, the wire is taken to a sending room 7 from an entrance 6b of a cooling apparatus 1. An inert gas 2 which is cooled to a particular temperature is sprayed spirally and as in laminar flow state to the entire outer surface of the wire 5 in the sending room 7. By such a process, the wire 5 cooled directly by the dried gas 2 is effectively cooled until it is taken out from an exist 6c provided in the central part of the low part in the sending room 7 of the apparatus 1. Accordingly, effective cooling and high speed application of the protection film coating can be carried out to the wire which is pulled at a high speed.
