METHOD OF THERMAL-DIFFUSION ZINCIFICATION OF ARTICLE FROM FERROMAGNETIC MATERIALS

摘要

1. A process for the thermal diffusion galvanizing products from ferromagnetic materials, comprising feeding the product or product parts in an electric installation retort shaped as inducers, uniform filling saturating zinc-containing mixture, sealing the retort, the retort after sealing inductors placed inside a heating installation and heating is carried out by eddy currents during rotation retort to a predetermined temperature and then disconnect the power supply installation inductors withstand retort in a heating Settings for a period of time required to form the desired coating thickness, while during galvanizing is carried out continuous discharge of excess pressure in the retort, and then extracted retort of the inductors and subjected to forced cooling by the rotation of the retort on the process table, characterized in that the placement of the retort within inductors is performed by means of additional mechanisms of longitudinal movement, heating the retort to a predetermined value of the surface is carried out in two stages, wherein n the first step is heated to a temperature equal to 85-90% of the predetermined value, which is measured in the zone by the inductors is further installed in these zones thermocouple when the temperature in the inductor value of said range zone, cut off electric power inductors retort and moved toward the exit of the heating installation by an amount equal to the distance between the inductors, then include electric power and additional inductors retort rotation mechanisms, their moment of contact with the surface
