Abstract
The invention provides an improved ion nitriding furnace. The new ion nitriding furnace for metal surface strengthening comprises a furnace cover, a furnace bottom, a furnace body, an air guide duct, a vacuum system, an air supply system, a power supply system and a cooling system, wherein a hot air circulation blower is mounted above the furnace cover. In the new ion nitriding furnace for metal surface strengthening, the air guide duct is mounted in the hearth. When the furnace works, hot air is circulated in the hearth along the air guide duct in the rotation process of the hot air circulation blower, thereby ensuring that heating is particularly uniform. Thus, workpieces of different sizes can be processed in the furnace, nitriding layers can be the same, energy can be saved, and no arc strike is caused; slender rod workpieces can be treated; and the product is qualified and has no bending.
Description
Technical field
The present invention relates to the nitriding treatment field, particularly a kind of Novel belt hot air circulation ion nitriding furnace.
Background technology
Ion nitriding furnace is that nitrogenous rarefied gas is ionized in DC electric field, and positive ion bombardment metal parts surface formation nitride layer is to reach case-hardened equipment.
Ion nitriding all has remarkable nitriding result for spheroidal graphite cast iron, steel alloy, stainless steel, sintered metal product, titanium alloy, rapid steel, tool steel etc.
Summary of the invention
The invention provides a kind of improved ion nitriding furnace, a kind of new metal surface enhanced ion nitriding furnace that is used for, formed by bell, furnace bottom, body of heater, ventilating duct, vacuum system, airing system, power supply system and cooling system, a kind of hot air circulation blower is installed above bell.
The described new metal surface enhanced ion nitriding furnace that is used for is equipped with ventilating duct in burner hearth inside.
Shove charge workpiece Φ 3 * 400mm push rod, 395 ℃, 90min reaches specification of quality fully, and is qualified.
When stove was worked, during the hot air circulation blower rotation, hot blast made heating even especially along ventilating duct at the burner hearth internal recycle.Can process the workpiece of different size in such stove, make infiltration layer consistent, energy-conservation, do not beat arc, the slender rod type workpiece is processed, qualified product not only, and without bending.
Description of drawings
Fig. 1 is Novel belt hot air circulation ion nitriding furnace structural representation of the present invention;
In figure, 1 is hot air circulation blower, and 2 is fan, and 3 is ventilating duct.
Fig. 2 is shove charge workpiece push rod schematic diagram.
