Steel sleeve ,aluminum foil steel sleeve are widely used in aluminum foil aluminum foil board with stainless steel and other industries to the foil of zone plate coiling commonly used specifications for 565*505*1500565*505*1550665*605*1700665*605*1850...

Due to the high-speed rotation of Centrifugal CastingAluminum Rolling Mill Winding Spools, there are strict requirements on the concentricity and dynamic balance of the Aluminum Rolling Mill Winding Spools, which has a great impact on the product qualification rate and later reprocessing, so the best production process of Centrifugal CastingAluminum Rolling Mill Winding Spoolis centrifugal casting.Sometimes products need heat treatment, which puts forward higher requirements for steel sleeve, general carbon steel such as: ZG45, ZG55 strength is low, not resistant to high temperature, easy deformation;High-demand applications need to use such as :ZG35CrNiMo, ZG25Cr2Mo1V, 35CrMo and other high temperature resistant, not deformation alloy steel sleeve.

Starting from the centrifugal casting blank, each piece is numbered, and the number runs through every process of parts processing. Every process has a strict machining precision process card, with detailed field records and on-site quality inspectors to track the whole process.

Production inspection is carried out in accordance with the first part inspection, self-inspection and special inspection, so as to ensure the processing accuracy and traceability of each Centrifugal Casting Aluminum Rolling Mill Winding Spools product.

Centrifugal casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the liquid metal is centrifugal motion to fill the mold and form a casting. Due to the centrifugal movement, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; the cylindrical inner hole can be obtained without the core; it is helpful to eliminate the gas and inclusions in the liquid metal; it affects the metal The crystallization process improves the mechanical and physical properties of the casting.

Generally, the main requirements for roughing rolls are strength and thermal cracking resistance; the working rolls of a small 20-high rolling mill weigh only about 100 grams, while the weight of the back-up rolls of a wide and heavy plate mill has exceeded 200 tons. When selecting the roll, first select the main material (various grades of cast iron, cast steel or forged steel, etc.) that is safe to bear according to the basic strength requirements of the rolling mill.

The speed of the finishing roll is relatively high, and the final rolled product must have a certain surface quality. The main requirements for it are hardness and wear resistance. Then consider the wear resistance of the roll when it is used. Due to the complex wear mechanism of rolls, including mechanical stress, heat during rolling, cooling, chemical action of lubricating medium, and other effects, there is no unified index for comprehensively evaluating the wear resistance of rolls. Since the hardness is easy to measure and can reflect the wear resistance under certain conditions, the radial hardness curve is generally used to approximate the wear resistance of the roll.

When selecting rolls, some of the performance requirements of the rolls are often opposed to each other. The purchase and maintenance costs of the rolls are very expensive. Therefore, the technical and economic advantages and disadvantages should be fully weighed to decide whether to use cast or forged, alloy or non-alloy, single material or composite material.
