List of operations for the technology introduction:
- calculation of streams quantity and arrangement of rings on cylinders;
- development and submission of drafts of cylinders (axes), hard-alloyed rings, fastening and fixative elements;
- development of a technology for assembling and disassembling of bandaged cylinders;
- technology for cooling of bandaged cylinders during operation;
- training and control over compliance with the technologies of assembly, cutting and cooling of bandaged cylinders during operation
Bandaged cylinders are employed in operations on finishing groups of small-section mills for production of rings and armature.
Hard-alloyed material has gauge hardness НRС 77...88 which gives high wear resistance, strength and resilience.
Advantages of given technology:
- increase of wear resistance of gauges twentyfold and more comparing to other steel and cast iron cylinders;
- decrease of technological shutdowns of mills, associated with transfer of gauges and cylinders;
- obtaining high quality of surface;
- achieving stable receipt of profile geometrical sizes.
