Abstract
A kind of metal plating thermal treatment process, it is characterized in that: (1) electrolytic coating is put into neutrality or reducing atmosphere heats, (2) when electrolytic coating melting point metal is less than core fusing point, electrolytic coating METAL HEATING PROCESS to higher than electrolytic coating melting point metal temperature, then cool, (3) when electrolytic coating melting point metal is greater than core fusing point, electrolytic coating METAL HEATING PROCESS to close to core melting temperature, then cool.Above-mentioned metal plating thermal treatment process, close to or continue to carry out shock treatment to electrolytic coating by ultrasonic wave when reaching top temperature.
Description
Technical field
The invention belongs to metallic substance Field of Heat-treatment, especially a kind of metal plating thermal treatment process.
Technical background
In order to strengthen the corrosion resistance of metallic substance, improve the physicochemical property of metallic substance, people plate layer of metal protective layer outside metallic substance of being everlasting.The method of metallizing protective layer has the method such as hot dip and plating, and hot dip is exactly that the plated metallic substance of needs is put into coated metal melt, and exactly steel pipe is put into zinc melting of metal liquid as given during steel tube hot galvanizing, such steel tube surface just covers one deck zinc.Plating puts into electrolytic solution steel pipe exactly, just covers one deck zinc by electrochemical method in steel tube surface.Calorizing tectum compact and firm, but cost is high, and electrochemical plating cost is low, but tectum is insecure loose, is much that slabbing drops when corrosion.And core fusing point can not adopt calorizing when being less than coating fusing point.
Summary of the invention
The invention provides a kind of metal plating thermal treatment process, object is heat-treated electrodeposition of metals, makes electrolytic coating reach the effect of hot-dip coating.
A kind of metal plating thermal treatment process, it is characterized in that: (1) electrolytic coating is put into neutrality or reducing atmosphere heats, (2) when electrolytic coating melting point metal is less than core fusing point, electrolytic coating METAL HEATING PROCESS to higher than electrolytic coating melting point metal temperature, then cool, (3) when electrolytic coating melting point metal is greater than core fusing point, electrolytic coating METAL HEATING PROCESS to close to core melting temperature, then cool.
Above-mentioned metal plating thermal treatment process, is characterized in that: (1) when electrolytic coating melting point metal is less than core fusing point close to or continue to carry out shock treatment to electrolytic coating by ultrasonic wave when reaching electrolytic coating melting point metal temperature.(2) when electrolytic coating melting point metal is greater than core fusing point, electrolytic coating METAL HEATING PROCESS to close to core melting temperature, continuing to carry out shock treatment to electrolytic coating by ultrasonic wave close to during core melting point metal temperature.The object done like this be by ultrasonic impact process electrolytic coating is become finer and close, when being greater than core fusing point for electrolytic coating melting point metal especially, this treatment effect is just more remarkable.
Accompanying drawing explanation
Fig. 1 is present invention process schematic diagram
1---steel metal wire 2---resistive heater 3---ultrasound source 4---power wheel 5---power wheel
Embodiment
The steel metal wire 1 having electroplated zinc electrolytic coating is had as shown in Figure 1 between power wheel 4 and 5; first by resistive heater 2, steel metal wire 1 is heated to the fusing point 420 DEG C of zinc; then by the ultrasonic wave that ultrasound source 3 sends, shock treatment is carried out to steel metal wire 1; steel metal wire 1 after ultrasonic impact process is come out of the stove after overcooling again; above-mentioned heat-treatment process is all carried out under reductibility gas shielded, and zinc electrolytic coating can be prevented so oxidized.
Claims (1)
1. a metal plating thermal treatment process, it is characterized in that: (1) electrolytic coating is put into neutrality or reducing atmosphere heats, (2) when electrolytic coating melting point metal is less than core fusing point, electrolytic coating METAL HEATING PROCESS to higher than electrolytic coating melting point metal temperature, but lower than core melting temperature, continue to carry out shock treatment to electrolytic coating by ultrasonic wave.
