METHOD FOR SHEET ALUMINUM RECEIVING

摘要

FIELD: metallurgy. ^ SUBSTANCE: it is implemented dissolution of lead in tank at temperature 800-900C. Then it is implemented charge of preheated till the same temperature melted aluminum on surface of melted lead in volume which is necessary for receiving of specified thickness of shit. Further it is implemented soaking and temperature pulldown of lead and aluminum melts till temperature freezing temperature of aluminum. Solidified layer of aluminum is taken off from lead melt with further pollution from sticked residuals of lead and cooled down. In particular cases implementation of invention, temperature of lead and aluminum melts is reduced till 450C. Soaking is implemented during 5-10 minutes. Sheets made of aluminum are manufactured in vacuum. ^ EFFECT: aluminum sheet with perfectly plain and parallel surfaces. ^ 4 cl, 1 dwg
