Steps of steel processing process
steel processing should be carried out at normal temperature, and the steel bar should not be heated in the process. The steel bar bending forming can be carried out by the steel bar bending machine, the four-head steel bending machine and the hand bending tool. Rebar bending should be completed once, not repeatedly bending.
(1) reinforcement processing includes straightening, derusting, cutting, lengthening, bending molding, etc.
(2) reinforcement should be straightened by mechanical equipment without extension function, or straightened by cold drawing. When the cold drawing is adopted, the cold drawing rate of the \HPB300 circular steel bar should not be more than 4%; The cold drawing ratio of HRB335, HRB400, HRB500, HRBF400, HRBF500 and RRB400 ribbed steel bars should not be greater than 1%.
(3) steel bar derusting: two is in the steel bar cold pull or straightening process of derusting · two can be used mechanical derusting machine derusting, sandblasting derusting, pickling derusting and sub-work derusting, etc.
(4) The steel bar cutting can be carried out by steel bar cutting machine or manual hydraulic cutting machine. No horseshoe shape or bending of the steel bar shall be allowed.
(5) steel processing should be carried out at normal temperature, and the steel bar should not be heated in the process. The steel bar bending forming can be carried out by the steel bar bending machine, the four-head steel bending machine and the hand bending tool. Rebar bending should be completed once, not repeatedly bending.
