Applications of Gas Nitriding Furnace
The Gas nitriding furnace is mainly used for all kinds of steel machinery parts, such as crankshaft, piston rod, steel cylinder, brake pad, mold, and other nitriding heat treatment, in order to improve the surface hardness and wear resistance of the workpiece.
Introduction of the Gas Nitriding Furnace structure
RN series pit type gas nitriding furnace is made of metal skeleton shell, which is made of the formalized high purity fiber folding block furnace. There is a stainless steel welded sealed furnace tank in the heating chamber, the upper part of the furnace is equipped with a vacuum rubber seal ring, the lower part is a water cooling jacket, the top of the furnace cover is equipped with a water cooling equalizing fan, the air volume is about 40 cubic meters per minute, every 10 seconds can cycle the furnace gas, ensuring the uniformity of furnace gas and temperature. The water pipe interface on the furnace cover is connected in series, and only the water inlet and outlet are reserved at the lifting mechanism.
In order to ensure that the sealing ring is not burned out and aging, the furnace cover and tank flange are double-layer water-cooled structures. The cooling water pipe should be no less than Ф20 mm in diameter, The inlet is curved under the furnace cover.
The flange of the furnace tank is pressed on the furnace cover plate.
The heating element is made of a flat high-resistance alloy resistance band (0Cr21Al6Nb) with a waveform and is mounted on a fiber folding block in the heating chamber with a high-aluminum screw.
Ammonia by ammonia gas dryer, rotor flowmeter through the furnace central and bottom tank into the furnace chamber, the furnace bottom inlet pipe is processed into a circle, in the inside of the six Ф 3 holes; Stainless steel tubes by enters the furnace to the outer wall of furnace tank, stainless steel pipe for Ф 10 x 1.5.
The lifting system of furnace cover adopts a hydraulic method, easy to operate, simple structure, reliable performance, low failure rate;
There are a drop injection port and an exhaust port on the cover of the furnace.
The air inlet bends under the cover plate of the furnace.
