Pit nitriding furnace Pit gas nitriding furnace

There is no difference between a pit nitriding furnace and a pit gas nitriding furnace. Pit gas nitriding furnace is the industry standard name, the model is RN, and later many people like to search with simple keywords in the search, so that there is the name of pit nitriding furnace.

The pit nitriding furnace is composed of a furnace shell, a furnace lining, a furnace lid lifting mechanism, a fan, a muffle tank, a heating element and an electronic control system.

It is mainly used for gas nitriding of carbon steel parts. The plant is equipped with a dripping device and can also be treated with gas nitrocarburizing (soft nitriding). When ammonia gas and instillation devices are not used, it can be used as a general pit tempering furnace.

Changxing's stove can't be bought.

It makes no difference.

I'm making electric stoves. To do nitriding furnace is our company's strength.

The multi-purpose furnace can be used to generate gas to carry out the nitriding process, the ratio of generator gas and ammonia is 1:1, because the generator gas contains 40% hydrogen, the nitrogen potential obtained will be lower than normal, and the low nitrogen potential to do soft nitriding although the time will be extended, the white bright layer is slightly slower, but it is easier to meet the requirements for some products with less requirements and no white bright layer.

If there is no gas, only methanol and ammonia atmosphere, there will be some problems in low-temperature cracking of methanol, for example, the safety is worse than the gas generated, and the calculation of nitrogen potential is more troublesome. Because of this, Wuhan Huamin's hydrogen probe can be used, integrated structure, imported MEMS thermal conductivity sensor, so that the measurement gas pool only has a few microliter volume, compared with the traditional structure, the temperature drift is small, the monitoring accuracy is high, and the sensitivity is high.

Pit furnace can also use methanol or gas to make carburizing agent, a group of wheel samples have the effect of reducing nitrogen potential, this effect is not unfavorable to all parts, some parts are easier to get stable quality in this atmosphere state, such as the nitriding process that requires no (less) white bright layer, and the nitriding process with strict requirements for loose white bright layer, etc., can be used with hydrogen-containing gas to make carburizing agent. If Wuhan Huamin's hydrogen probe is selected, it can effectively prevent the nitriding culture atmosphere from crystallizing at low temperatures to block the gas path and pollute the gas pool. This results in a complete record of changes in the hydrogen content in the carburizing atmosphere.

Nothing is perfect, each furnace has its own advantages, the requirements of the process are ever-changing, and the most important thing is to choose the right method. If you want to choose a suitable heat treatment atmosphere control system, welcome to contact Wuhan Huamin.

Hello, pit gas nitriding furnace is a commonly used heat treatment equipment in the side shed, and its operation process is as follows:1Preparation:

Put the parts to be processed into the furnace and set parameters such as temperature, nitriding time, etc., as needed. 2.Start the stove:

Start the stove according to the instructions for the stove disturbance and heat the stove to the set temperature. 3.Gasping:

After the furnace reaches the set temperature, nitrogen is added to the furnace to maintain a certain nitrogen flow and pressure. 4.Nitriding:

Keep the furnace at a set temperature and let the nitrogen penetrate into the surface of the parts for a certain period of time to achieve the purpose of enhancing the surface hardness and wear resistance of the parts. 5.Cooling:

Once the nitriding is complete, the furnace is cooled to room temperature and the processed parts are removed. It should be noted that the operating procedures of the furnace and the operating regulations of the safety baggage should be strictly followed during the operation process to ensure the safety of the operator and the normal operation of the equipment. Off-topic expansion:

Pit gas nitriding furnace is a commonly used heat treatment equipment, which is widely used in machinery, automobile, aviation and other industries. Its main advantages are large penetration depth, good treatment effect, and high production efficiency. At the same time, a variety of gas permeation treatment can also be carried out according to different process requirements, such as nitriding, carbonitriding, etc.

Summary. Hello dear <>

The operation process of the pit gas nitriding furnace is that the workpiece is pre-cleaned, loaded, vacuumed, ion-bombarded cleaned, nitrided, cooled, and inspected.

Pit gas nitriding furnace operation process.

Hello dear <>

The operation process of the pit gas infiltration start-up nitrogen furnace is to include the chain, the workpiece is pre-cleaned, the workpiece is washed, the card is loaded, the vacuum is pumped, the ion bombardment is cleaned, the nitriding is cooled, and the inspection is carried out.

1.The gas nitriding furnace before nitriding must be a workpiece that has been normalized or quenched and tempered first. 2.

First, use gasoline and alcohol to scrub the surface of the workpiece of the gas nitride Wu Yuancong furnace, and there shall be no rust spots, oil stains and dirt. 3.After loading into the furnace, tighten the lid compression bolts symmetrically.

4.The water inlet of the furnace tank and lid is drained with cooling water for circulating water cooling. The lower end of the cooling water of the pipe on the lid of the gas nitriding furnace is the inlet water, the upper end is the outlet water, the furnace tank is separately inlet and drained separately, and all the water pipes of the gas nitriding furnace cover can be connected in series according to the principle of low in and high out, with water entering from one port and draining from one port.

5.Before the gas nitriding furnace heats up, nitrogen should be sent to exhaust, and the flow rate should be more than double that of use. After exhausting for 10 minutes, set the temperature control instrument to 150, the automatic heating switch is turned on, the gas nitriding furnace is heated 150 while exhausting to keep the exhaust for 2h, and then the temperature control instrument is set to 530, the ammonia flow rate is smaller, the positive pressure in the furnace is maintained, and the exhaust port has a small upward pressure of the air flow, when the furnace temperature rises to 530 cavity, the constant temperature and constant flow nitriding for 3-20h, and then the ammonia pressure is increased a little more, so that the exhaust gas maintains a moderate pressure, nitriding 4-70h, and then the ammonia pressure is adjusted to a small amount, and the nitrogen is reduced for 1-2h. Cut off the power supply of the cavity cherry blossoms, give a small amount of ammonia gas, maintain positive pressure in the furnace, and stop the ammonia supply when the furnace temperature drops below 150.

The gas nitriding furnace has the characteristics of low processing temperature, short time, small deformation of the workpiece, properties: high fatigue limit and good wear resistance. I wish you a happy life!

Hope mine is helpful to you ha.
