Material and Chemical Composition of Customized Cast Steel Sleeve for Cold Rolling Mill
1.1 Material Standards
Brand: 35CrMoV (GB/T 3077-2015)
Category: Low alloy high-strength cast steel (weldable, heat treatable)
Alternative materials: 34CrNiMo6 (DIN), AISI 4340 (American standard)
1.2 Chemical composition (%)
Element C Si Mn Cr Mo V P S
Range 0.30-0.38 0.20-0.40 0.50-0.80 0.90-1.20 0.20-0.30 0.10-0.20 ≤ 0.025 ≤ 0.025
Key features:
The Cr-Mo-V combination provides excellent hardenability, high temperature strength, and fatigue resistance.
Low S/P content reduces thermal brittleness and improves impact toughness.
Description of heat treatment of 35CrMoV cast steel sleeve
We will conduct heat treatment strictly for 35CrMoV cast steel sleeve which have the specific demand in mechanical property, also in corresponding testing of the mechanical property, make sure every 35CrMoV cast steel sleeve product to achieve the best condition and customers’ good results.
Mechanical processing parameters of customized cast steel sleeves for cold rolling mills
4.1 Dimensions and tolerances
Parameter requirements
Inner hole diameter IT6 grade (H6), Ra ≤ 0.8 μ m
Outer diameter IT7 grade (h7), Ra ≤ 1.6 μ m
Cylindricity ≤ 0.01mm/100mm
Coaxiality ≤ 0.02mm (bearing mating surface)
4.2 Key Processing Techniques
Precision boring/honing: Ensure the accuracy of the inner hole (such as for bearing fitting).
Grinding: Processing with an external cylindrical grinder to avoid thermal deformation.
Dynamic balance (if rotating at high speed): residual unbalance ≤ G2.5 level (ISO 1940).
We used our independent dedicated device-hole drilling machine which is researched and developed by ourselves, it also obtain the national patent. The machine is provided with good rigid, no returning clamp and machine and high accuracy on the processing of machining. Through continuous improvement, our company formed a integrated processing technic system to ensure concentricity, cylindricity, degree of symmetry and dynamic balance of the 35CrMoV cast steel sleeve. Specific accuracy tolerance and geometric accuracy tolerance is strictly according to the customers’ requires.
In terms of inspection, in order to safeguard the benefits of customers and ensure better quality of 35CrMoV cast steel sleeve products, we have conducted various tests on mechanical properties after heat treatment in addition to conventional dimensional inspection.Ring belt dynamic balancing machine can be 100% dynamic balancing test.
