High-speed wire rod plant process design and
quality control of steel cord

Abstract
This design which is based on Anshan Iron and Steel Wire Factory is planted 550,000 t
annual workshop for high-speed wire rod plant technology. Typical produce is the Q235，
Φ6mm wire. Design specification includs literature review，workshop process design and
project. The literature review part describes the basic knowledge of wire rod production and
the current situation. Design part (from chapter to chapter IX) describes the main program and
the process of product design and development，production and equipment selection，process
parameter calculation and checking，annual basis，the guide position adjusting device and mill，
shop flat design and layout drawings，as well as technical and economic indicators and
environmental protection measures. The major topics describes method and technology in
quality control of steel cord.
