Technical characteristics of steel strip galvanized mandrel

The mandrel of the decoiler and rewinder is an important part of the steel strip galvanizing production line. The steel strip drum has high tension and high precision. Each part of the drum requires strict requirements from design to processing. The verticality, parallelism and coaxially of the workpieces are strictly according to the requirements of the drawing. Especially for its root chamfering treatment. The outer arc of the fan plate and the supporting sleeve are nitrided to increase the wear resistance and fatigue resistance. Process equipment is used in the processing. Meanwhile, the German Ximark Shougang project exported by our company before meets their acceptance standards.
