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.
