China (vacuum)  Gas Nitriding Furnace For Aluminum Extrusion Die

Product Abstract:

The extrusion die of aluminum extrusion works at the condition of strong extrusion force and high temperature, it needs to stand the very strong friction. So after the extrusion die used a certain time, it needs to use the nitriding furnace to do hardening process. Gas nitriding furnace is used the ammonia gas to resolve into nitrogen for nitriding process.
Product Description

China Gas Nitriding Furnace For Aluminum Extrusion Die

This equipment comes from our cooperation manufacturer

Nitriding process divides into two kinds: one is gas nitriding which used the ammonia gas for medium; the other is liquild nitriding which used the nitrate liquid as medium, also called "salt bath". But it is hard to buy the nitrade chemical and hard to wash the die surface, so gas nitriding is more popular.

We have three kinds of nitriding furnace:

1. Normal type nitriding furnace--(economic type) , mean operation by manual. Structure is sample and easy to maintain; the furnace structure can meet the extrusion dies nitriding process requirement. If you want to reduce the machine cost, this is a good choice.   
 
2. Vacuum impulse type nitriding furnace, mean it is equipped with Vacuum Impulse system, during the process of nitriding, the system is automatic, but the temperature setting for start is manual type. Furnace temperature is controlled by temperature control system, temperature control is controlled by temperature control closed-loop which is made of thermocouple, temperature control meter and Power regulator (PID). Control cabinet setup with overheat alarm, Digital instrumentation equipped an intelligent PID for temperature control precision of ±1? and with the function of self-turning, self-adopting, overload, over pressure audible and visual alarm, power-off protection, eight-section temperature option, heat preserving technological curve and so on.
 
3. Nitriding furnac with Nitrogen control instrument and hydrogen analysis meter to achieve automatic control the nitrogen potential, no need to adjust the temperature and ammonia gas.
 
In addition, our nitriding furnace can be equipped with advanced and stable power regulator.This system is manly used for adjusting the power according to actual production requirements and based on stable operation performance for save electricity energy. (If you need this system, please notice it when you send us inquiry)

The aluminum extrusion die works at the condition of strong extrusion force and high temperature, it needs to stand the very strong friction. So after the aluminum extrusion die run for a certain time, it need to use the nitriding furnace to do hardening process treatment, so the aluminum extrusion dies life can be longer and aluminum profile surface will be smoother. 

We are specialized in the production of gas nitriding for hardening aluminum extrusion die, we have been exported to Pakistan, Egypt, Sri Lanka, we have rich experience of aluminum extrusion die treatment, we can supply the nitriding process treatment guidance. 

Application of gas nitring furnace
This nitriding furnace is a series of batch-type pit-type controlled nitriding furnaces and is used for nitriding metallic tools and dies, camshafts, precision gears, etc.  If this nitriding furnace is equipped with a KRN-W or WPB-N series control panel, the nitriding atmosphere, temperature, operating time, and gas and liquid flow can be controlled automatically.  This series can also be used for various applications including soft-nitriding, tempering, and stress relieving of steel parts, as well as solution treatment of nonferrous metals.

Features of nitriding furnace
1. This nitriding furnace series is furnished with a KRN-W nitrogen potential micro-processor.  It measures, adjusts and records the nitrogen potential, temperature, time, gas and water flow automatically.
2. The unique doubly insulated furnace and circulating fan mechanism allows nitrogen potential uniformity better than ±0.1%, and internal pressure greater than 250 mm H2O.
3. The advanced ceramic tile lining greatly insulates the furnace, significantly speeding heating and thereby saving up to 20% in energy usage.
4. The rapid-cooling fan system shortens the production period greatly.
5. If this nitriding furnace is equipped with a vacuum system, it can be fitted for controlled pulse-nitriding.

Frequency conversionpower regulator for energy saving function. (Extra function, if clients need it, we will make it, usually we don’t supply because it must need us send technicist to clients’plant to install and trial run.)

The function is same with the frequency conversion type air-condition for saving electricity. 
The nitriding furnace is equipped with advanced and stable Frequency conversion device. This system is manly used for adjusting the power according to actual production requirements and based on stable operation performance: while large loading and charging, turn up the power; while small loading and charging, turn down the power. At the same time, turning up the power meets the temperature rising quickly according to technological demand so that save the electricity energy. If you want to control deflection, turning down the power can reduce the deflection to minimum. 
 
Additionally, there are manual and auto function for options, so the user can set the time for rising up to specified temperature, then the system will implement the setting parameters automatically. And the actual power can be displayed on display device. This device can save the electricity consumption, reduce the enterprise production cost and improve clients profit and their competitiveness.  
But for this furnace must need to send our technicist to clients plant for installation and commissioning. Because some of our clients no need we send technicist to their plant for saving the budget, so we don't send technicist to their plant, we will use the emails and pictures to guide them to install because the simple type furnace and pulse type furnace is simple, we know our furnace details like the palm of one's hand. But frequency conversion type is more complicated, clients can not handle the installation by themselves, so we need our technicist to install and trial run.
