Equipment for the treatment of melts via mechanical vibrations
The present paper describes the assembly of a vibrating equipment. This system has a single degree of freedom and viscous absorption. The vibrations are generated by an eccentric revolving table. The equipment comprises an a.c. motor (Pn = 2,2 Kw, I= 165 A, n = 17.000 r.p.m.), a mechanical vibrating unit, a VLT 5008 Danfoss frequency converter, a Kw 3072 HBM measurement intensifier, an oscilloscope, a B12/1000 HOTTINGER BALOWIN MESS TECHNIK accelerometer, cast iron table, rubber supports. The equipment generates mechanical vibrations which applied to the liquid alloys during solidification alter the solidification conditions and improve the mechanical, tribological, physical and chemical properties of the respective alloys.
