ال rolling mill wire rod process is a critical component of modern steel manufacturing, transforming billets into high-quality coiled rods used in construction, السيارات, and machinery industries. This article delves into the technical nuances of مصانع درفلة قضبان الأسلاك, integrating expertise from HANI TECH’s industrial solutions.
1. Fundamentals of Wire Rod Rolling
Wire rod production involves hot rolling steel billets through a series of precisely calibrated stands to achieve diameters typically ranging from 5.5mm to 42mm. ال rolling mill wire rod system consists of:
- أفران إعادة التسخين (pusher/walking beam type)
- Roughing/intermediate/finishing mill stands
- Water cooling boxes
- Laying head and coilers
وفق قسم مطحنة الدرفلة في HANI TECH, modern مصانع قضبان الأسلاك achieve speeds up to 120 m/s with tolerances of ±0.1mm, leveraging advanced automation for consistent quality.
