1. Equipment required for steel bar production (1) Preparation before construction 1. Mechanical equipment steel bar cutting machine, steel bar straightening machine, steel bar bending machine, steel bar bending machine, spot Welding Machine, butt welding machine, arc welding machine and corresponding lifting equipment . Garden tools are also known as outdoor tools. They are a group of Power Tools designed for outdoor use,e.g. in the garden.

2. Materials This project requires the use of various steel bars of various specifications and grades of neiszpwkd, and must have a factory certificate. After entering the factory (field), it must be verified by physical properties. For imported steel, a chemical test is added, and it can be used after passing the test.
3. Operating conditions (1) All equipment is in good repair before operation, to ensure normal operation, and to comply with safety regulations.
(2) Rebar extraction. Rebar drawing personnel should be familiar with the drawings, audit records and construction specifications, fill in the rebar drawing table according to the specifications, shapes, sizes and quantities of the rebar required by the drawings to calculate the amount of rebar.
(B) Operation process 1. The surface of the steel bar should be clean, and the adhered oil stains, soil, neiszpwkd floating rust must be cleaned before use, and can be combined with the cold drawing process to remove rust.
2. Rebar straightening can be straightened mechanically or manually. The straightened steel bars must not have local bending, dead bends, or small waves, and the surface scratches should not reduce the steel bar section by 5%.
Cold drawing rate of steel bar straightened by cold drawing method:
The cold drawing rate of grade â… steel bar should not be greater than 4%.
The cold drawing rate of grade â…¡ and â…¢ steel bars should not be greater than 1%.
The rings of prefabricated components shall not be cold-drawn, and can only be made of Class I hot-rolled steel bars.
3. Rebar cutting should be based on the number, diameter, and length of the rebar, and the length and length are matched. The long material is broken first and then the short material is cut.
