Description: Cold-rolled steel strips and sheets typically range from 0.1-3mm in thickness and 100-2000mm in width. They offer advantages such as a smooth surface, high
Solving the Problem: How to optimize rolling mill roll usage Increasing roughing mill production capacity High-chromium steel rolls were developed in Europe in the early
Slitting Knife Steel Sticking Steel sticking on the slitting knife refers to the phenomenon where slag adheres to one or both sides of the slitting
1.1 Pre-Assembly Preparation (1) Verify dimensions and accuracy of new roll components against equipment drawings. Check groove patterns using templates. Report any discrepancies to relevant
Iron Oxide Scale Formation and Solutions Formation Mechanisms: Primary scale develops during slab heating, appearing as random spots and streaks. If not properly removed before
The finishing mill unit of our high-speed wire rod plant utilizes a 45° top-crossing cantilever design from Danieli, commissioned in 2015 for producing Φ5.5-Φ16mm wire
Morphology and Causes of Scale Defects The “third scale” defect originates from oxide film spalling on finishing mill work rolls. Front-stand rolls operate under severe
Hot-rolled strip steel serves as a crucial material across numerous industries. With intensifying market competition and rising customer expectations, quality control becomes increasingly vital. Common
Causes of Adhesion Excessive tension during rolling or coiling Poor strip shape (edge waves, center waves, multiple waves) Irregular coil winding, especially in thinner gauges
1. Rolling Force Control Excessive rolling force complicates shape control and causes uneven roll temperatures, reducing bearing capacity. New work rolls typically employ higher tension
