Process specification for powerful spinning of high-strength steel
1 Scope
This standard specifies the process specification for high-strength steel strong spinning, including process content, process preparation, spinning forming and post-spinning treatment.
This standard applies to the powerful spinning process of alloy structural steel cones and cylindrical parts with a yield strength of over 800MPa.
This standard does not apply to hot spinning process.

3 Terms and definitions
The following terms and definitions defined in GB/T 8541 apply to this document.
3.1
Arc-shapedroler
The rotary wheel is a rotary wheel whose working profile is composed of an arc [see Figure 1a)].
a) Circular arc rotating wheel b) Double cone surface rotating wheel

3.2
Double-tapered surfacesroler
The working profile consists of two cones and a rotating wheel composed of a transition arc. Its profile is generally composed of three parts, namely the front cone and the rotary wheel
Top fillet and back cone [see Figure 1b)].
The double cone wheel is divided into two types, one without calender angle and the other with calender angle (see Figure 2).
