Requirements for the mass and heating of blanks selection in automated ring-rolling complexes

The conditions for choosing a billet mass the manufacture of an ring part on automated ring-rolling complex, features heating billets in line and heat treatment manufactured parts are considered. expediency differentiated assignment tolerances rings’ sizes after rolling, depending their type, subsequent mechanical operation, is substantiated. Attention focused need to design technology with control parameters not only during cutting, pressing operations, but also before especially when using reheating. To evaluate technological temperature state blanks at different stages manufacturing line, it offered use billet’s “conventional temperature”, which determined 2nd zone from middle billet. single gas rotary-hearth furnaces annular justified. problems rolling complex synchronization determined. It shown that clock capacity significantly exceeds planned complex. concluded necessary develop software synchronous operation. proposed recommendations intended development support OJSC “PAK Plant” as “BELAZ-HOLDING”.
