required for reheating and rolling. Rolling Stands A sequence of fully automated and watercooled roll stands that gradually reduce billets to required sizes. Finished Products Billets are rolled into reinforcement bars. Small diameters rods are also produced at fast design speeds with precise tolerance control using a sixpass bar block.
Rebar. In the Philippines, the local term for rebars is " kabilya " but it may also be referred to by engineers and site personnel as reinforcing steel bars, deformed bars (debars) or concrete reinforcements. The PNS 49 is the national rebar standard, it details the technical specifiions of rebars per .
Choose the method you will use to tie the rebar. Most times, rebar is tied with annealed steel wire, either bought in four pound bulk rolls, or if using a bag tie spinner, in bundles of precut wire pieces with loops formed on both ends. The latter are easier for novices to use, but somewhat more expensive, the former is often the choice of experience rebar tiers (rodbusters).

18/06/2014 · Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
