Forging Process Flow Development for Plate Production

Abstract

Developed on the basis of the pilot and industrial work results, a process flow for the production of mono-block plates with 7600x7600x360 mm dimensions from a 290-ton ingot for subsequent 15H2NMFA steel bottom stamping, was carried out. A practical implementation of the developed procedure for the bottom production from mono-block large-sized plates was made. The basic technology for the mono-block plate production was applied in the conditions of Izhorskiye Zavody, OJSC and Atommash, OJSC, this technology provides for a minimum amount of reconstruction of the existing facilities of these enterprises.

The process of the mill feed flow along a curved acting face of a vibration mill screen

“…At the small (under 25°) and large (to 50°) angles β, a noticeable increase in the velocity of the balls is only observed at the amplitudes higher than 0.75 mm; at β = 37.5° the ball velocity markedly increases already at the amplitude of 0.5-0.7 mm. The literature recommends the vibration amplitudes to be not more than 0.5-0.8 mm for the vibration transportation [15]; thus, to stimulate the movement velocity and distribution of the balls on the acting face, β should range as 35-40° [17][18][19][20].…”
