Steel processing technology is an important link in the process of steel processing. This paper will introduce the related technologies of steel processing.

Cold drawing straightening

The cold-drawn elongation of HPB300 steel bar should not be greater than 4%.

Rust removal of steel bars

Rust removal during cold drawing and straightening; Mechanical derusting; Sand blasting for rust removal; Pickling and derusting; Manual rust removal.

You can use a steel bar cutter or a manual hydraulic cutter. The cut-off opening of steel bar should not be horseshoe-shaped or bent.

Steel processing temperature

Should be carried out at room temperature, steel bar shall not be heated during processing.
