T/CCMI 11-2021 Mechanical machining allowance and tolerance for large hot-rolled ring forging
Abstract
Main technical content: This document specifies the machining allowances and tolerances for large-scale hot-rolled ring forgings with an outer diameter of φ4000mm to φ10000mm, a wall thickness of 30mm to 850mm, and a height of 60mm to 1500mm, which are formed by radial-axial bidirectional combined rolling on horizontal ring rolling machines. This document is applicable to the machining allowances and tolerances of hot-rolled ring forgings made of structural steel, tool steel, stainless steel, heat-resistant steel, aluminum alloy, high-temperature alloy, and titanium alloy that are rolled on radial-axial bidirectional combined horizontal ring rolling machines. Other forging production equipment can also refer to this document for implementation. This document is applicable to hot-rolled ring forgings in the forging state.
