METHOD OF THE AERODYNAMIC STRENGTHENING OF A PRODUCT

摘要

A method of hardening products, comprising a hardening cycle consisting of heating the article to a predetermined temperature and exposure in the process of cooling the product of mechanical oscillation of sound frequency in the resonance chamber with the outlet passage, characterized in that, the processing for the two hardening cycles, each of which consists of heating to a temperature equal to 10% -30% product melting temperature and aging for a time equal to at least 1.6 minutes to the longest dimension of one millimeter solidified product subsequently aerodi amicheskogo audible feedback oscillation frequencies in aisles 160-800 Hz for a time equal to 30% -40% of the time delay - in the first cycle of hardening, and 20% -30% of the time delay - in the second cycle of hardening, with the feed air pressure in each of the cycles in the range from 1.5 bar to 2.0 bar, hour air consumption at the first cycle in a volume of 2.5-2.9 E with an increase of 70% -80% hour air consumption compared to the first cycle - at the second cycle after which produce two aging cycle at a temperature of 150-170 C ° for a time equal to the time in the Shutter speed, followed by cooling in air to complete cooling.
