Introduction
Steel sleeve is also called sleeve, steel spool, cast steel sleeve,rolling mill sleeve or rolling mill bushing,mainly used in the aluminum processing factory to roll aluminum plates and aluminum foil, which is convenient for the turnover of aluminum products in the workshop and the annealing of strip coils. Steel sleeves are widely used in the processing of foil, strip and plate rolling in aluminum foil, aluminum plate, stainless steel foil strip and other industries.
Process Flow
Steel melting→Centrifugal casting blank→Sand blasting→Normalizing&tempering→Rough machining→Quenching&tempering→Finish machining inner hole→Chamfering→Finished cylindrical grinding→Dynamic balance test→Machining groove→Quality inspection→Packing and delivery
Characteristic
· Adopt advanced process of smelting and casting dedicated to ensure the steel core chemical composition in reliable and same properties.
· Using centrifugal casting is dedicated to ensure internal and external structure of sleeve have no defects such as cracks, slags, blowhole,blister etc..
. Adopt mature heat treatment technology to ensure the mechanical properties of the steel sleeve.
. Special steel sleeve processing and reasonable processing technology are used to ensure the technical requirements, such as the coaxiality, cylindricity and dynamic balance of the steel sleeve.
