Abstract
PURPOSE:To produce a wire rod having the properties suited for secondary working by performing hot finish rolling dividedly in two stages, providing a cooling stage for quick cooling of the material to be rolled at the intermediate stage and controlling rolling temps. and drafts. CONSTITUTION:A rolled steel rod 6 which is subjected to rough rolling and intermediate rolling is partially hot-finish-rolled with the 1st rolling mill 1', whereby it is made into a half-finished wire rod. Further, this wire rod is quickly cooled down to the temp. above the Ms point at the cooling rates at which at least the greater part of the structure is maintained at overcooled austenite in a cooler 2' having cooling means such as spray pipes. After the cooling, the material 6 is plastically worked by the remaining rolling reduction with the 2nd rolling mill 5 whereby it is finished to the prescribed size and shape while it is introduced with working strains. Thence, the rolled wire rold is bundled to a coil with a coiler 3, and the coil is properly heat-treated in a heat treatment device 4' consisting of a cooler, a heat-insulating device, a heater, a hardening-tempering device, etc., thence it is sent to a secondary working stage.
