Abstract
The present invention relates to a kind of cartridge of ion-nitriding furnace.The cartridge includes cylinder, cover, air inlet pipe I, air inlet pipe II, and the cover is fixed on cylinder, and barrel is provided with air inlet pipe I and air inlet pipe II, rotates cylinder interior air-flow, and the cylinder bottom is provided with several steam vents.The cartridge interior energy of ion-nitriding furnace of the present invention forms the air-flow of rotation, makes nitridation more uniform, and nitriding result is more preferably.
Description
Technical field
The present invention relates to a kind of cartridge of ion-nitriding furnace.
Background technology
The course of work of ion-nitriding furnace is：First put the workpiece in stove as negative electrode, body of heater is used as anode, then is passed through few
Amount ammonia, nitrogen or nitrogen argon mixture gas, then applying certain voltage in two interpolars ionizes nitrogen, i.e. with high speed impact work after nitrogen ionization
Part, the kinetic energy of ion are converted into heat energy by workpiece heat to nitriding temperature.A part of nitrogen of bombarded surface is captured after electronics directly
Surface of the work is penetrated into, the nitrogenous high Fe in evaporating state is formed on the surface of the workpiece, and is constantly spread to inside workpiece, from
And reach the purpose of nitriding.
The content of the invention
The present invention makes nitridation evenly by the layout of improvement air inlet pipe.
The invention provides a kind of cartridge of ion-nitriding furnace, the cartridge includes cylinder, cover, air inlet pipe I, enters
Trachea II, the cover are fixed on cylinder, and barrel is provided with air inlet pipe I and air inlet pipe II, rotate cylinder interior air-flow, described
Cylinder bottom is provided with several steam vents.
Air inlet pipe of the present invention I be preferably located at the top of barrel and direction of principal axis outlet from level to cylinder, it is described enter
Trachea II is preferably located at the barrel bottom immediately below air inlet pipe I and outlet straight up.
The ratio of I diameter of air inlet pipe of the present invention and barrel diameter is preferably 1：20-30.
The ratio of II diameter of air inlet pipe of the present invention and barrel diameter is preferably 1：20-30.
The present invention has the beneficial effect that：
The cartridge interior energy of ion-nitriding furnace of the present invention forms the air-flow of rotation, makes nitridation more uniform, nitridation effect
Fruit is more preferably.
