Description
Technical field
The utility model relates to a kind of dehydrogenation equipment, particularly a kind of piston rod dehydrogenation heating furnace body.
Background technology
Dehydrogenation, also claims dehydrogenation, is generally the operation to carrying out before and after plating, is applied in the part of high strength and high hardness especially in electroplating technology.
In iron part galvanizing process, outside the galvanic deposit of dezincification, be often attended by the side reaction of reducing hydrogen ions liberation of hydrogen.A hydrogen reduction part becomes gas effusion, and some penetrates in the dot matrix of coating and matrix metal lattice with the atom form of hydrogen and goes, and causes lattice twisted, and part internal stress increases, and coating and matrix become fragile, and people are referred to as hydrogen embrittlement.The mechanical property harm of hydrogen embrittlement to material is very large, if do not removed, can affect the life-span of part, even causing the malicious event of machine.Therefore some steel or for the part under special conditions, must carry out dehydrogenation, the galvanized workpiece that aircraft such as, use all will through dehydrogenation.On elastic part and high-strength steel, zinc-plated also needs carries out dehydrogenation.Dehydrogenation adopts heat treated method to be driven away from inside parts by hydrogen.Dehydrogenation effect and dehydrogenation temperature, soaking time are relevant.Temperature is high, and the time, long dehydrogenation was more thorough.But Heating temperature can not be too high, the zinc crystal structure distortion more than 250 DEG C, embrittlement, solidity to corrosion obviously declines.General use 190 DEG C ~ 230 DEG C, 2h ~ 3h.Carburizing part and soldering part dehydrogenation temperature are 140 DEG C ~ l60 DEG C, insulation 3h.
In any electroplating solution, due to the dissociation of water molecules, always there is the hydrogen ion of some amount more or less.Therefore, in electroplating process, while negative electrode precipitating metal (main reaction), with the precipitation (side reaction) of hydrogen.The impact of liberation of hydrogen is many-sided, wherein most importantly hydrogen embrittlement.Hydrogen embrittlement is one of hidden danger of quality the most serious in surface treatment, and the serious part of liberation of hydrogen in use just may rupture, and causes serious accident.
I takes charge of the Working environment of piston rod for high loading of production, therefore it is had to the requirement of high strength, high rigidity, and needs zinc-plated process, and traditional dehydrogenation stove uses inconvenience, and dehydrogenation weak effect.
