Automatic Cooling Bed

Re-bar core is still hot transfers heat outside to the case thereby tempering it results fine grained Ferrite-Pearlite structure at the Core & High strength to bars due to tempered martensite layer at the periphery of the rod. Also gets High ductility due to Ferrite Pearlite structure in the core. Bars have ability to be bent, galvanized and straightened without cracking or loss of tensile properties.

Subsequently, normalizing process starts where the bar cools down in atmospheric temperature and gradually attaining the same
