Process for production of 25mm high strength rock bolt tmt bar.

摘要

The present invention relates to a high strength ribbed rock bolt Fe 600 grade Thermo Mechanically Treated (TMT) for reinforcements for concrete or welded mesh, deformed by hot rolling and accelerated cooling, and it is directed to developing rock bolt grade TMT bars having higher production of high strength (YS: 600 MPa minimum) TMT bar in 25mm diameter for application as rock/roof bolt bar.
