Luoyang Yujie Industry&Trade Co., Ltd is one of the most experienced manufacturers and suppliers of steel rolling mill sleeve in China. Please feel free to buy cheap steel rolling mill sleeve for sale here from our factory. All customized products are with high quality and competitive price.
Description
Steel sleeve, also known as winding spools or occasionally rolling mill sleeves, are thick-walled tubes used for winding thin aluminium strips, aluminium foil or stainless steel thin sheet metal for transportation in the manufacturing process and storage. The wound metal is called a coil.
Product advantages
(1) Adopting the centrifugal casting process to achieve high density of materials.
(2) Use the special tool to process end face, taper and the outer circle according to inner hole to ensure beating of the taper, the concentricity and cylindricity of the steel spool.
(3)Selected materials: ZG35,KCP-12 and other high temperature resistant material,non-deformable alloy steel.

Heat treatment of steel sleeve:
Heat treatment is putting products after rough machining in a certain medium to change the surface or internal micro structure, and control the performance of a product by heating, heat preservation, cooling. Basic process of heat treatment: annealing, normalizing and tempering.
1. Annealing
Annealing is to heat the steel core to the appropriate temperature and then slowly cool the steel core to achieve or close to the equilibrium state.
2. Normalizing
Normalizing is making steel core cool after it reaches suitable temperature, the effect of normalizing is similar to annealing, commonly used to improve the cutting performance of material, also sometimes used for low requirements for some parts as the final heat treatment.
3. Quenching
Quenching is the rapid cooling process in the quenching medium of water, oil or other organic salts and organic water, after the heating of work piece. The steel is hardened after quenching, but it is brittle at the same time.
4.Tempering
Tempering is in order to reduce the brittleness of steel core. Place the steelcore which is after quenching in higher than the room temperature and under 650 ℃ for a long time of heat preservation, cooling again , this process is called tempering.
