The Largest Size Of Sleeve---liuzhou Yinhai Aluminium Industry Co.,Ltd.

Liuzhou Yinhai Aluminium Industry Co.,Ltd.   

Φ665*Φ605*2880

The current domestic production of the most wide 2800 cold rolling mill, the longest steel sleeve Φ 665 * 605 * 2880.

Our company adopts advanced smelting and casting technology, with the equipment has accurate inspection to ensure the chemical composition of the sleeve material is reliable and accurate, also has the same characteristics. Centrifugal casting is adopted to guarantee the inner and outer surface of the sleeve is free from defects such as cracks, slag inclusion, pores and sand holes. Adopt mature heat treatment technology to ensure the mechanical properties of steel sleeve.

For the inner hole processing of ultra-long steel sleeve, our company has developed and independently manufactured a special equipment -- variable speed self-feed deep hole boring machine;The machining of the outer circle is completed in the CNC lathe to ensure the dimensional accuracy of the outer circle of the sleeve.Through continuous improvement, our company has formed a set of perfect processing technology, to ensure the steel sleeve coaxiality cylindrical symmetry and dynamic balance and other technical indicators.
