| Abstract: | The causes of out-of-standard interval between transverse rib ends of rebar such as excessive wear of machining tool for finish-rolling groove,serious wear of finish-rolling groove in steel rolling process,etc.are analyzed.The interval between transverse rib ends of rebar meets the requirement of GB/T1499.2-2018 hot rolled rebar standard by replacing the machining tool of finish-rolling groove regularly,changing the machining method of transverse rib end in finish-rolling groove,and replacing the finish-rolling groove in time. |
