What is the maximum degree of vacuum air quenching furnace?

The maximum use temperature of our vacuum air quenching furnace is 1280 degrees Celsius, this maximum use temperature is the temperature when used under normal circumstances, and it can actually be increased to a relatively high temperature, but then it will cause damage to the furnace lining and furnace internals, reduce the service life of the furnace, and there is no problem in increasing the temperature, but at the cost of damaging the life of the furnace, in fact, the vacuum air quenching furnace is used for heat treatment, and there is not much steel that needs to be heated to such a high temperature, and the maximum of high-speed steel is only 1320 degrees. Except, of course, for vacuum furnaces used for smelting.

The vacuum quenching furnace is suitable for solution treatment and aging treatment of large and medium-sized vacuum product parts.

Vacuum high-pressure gas quenching furnace is a very advanced vacuum heat treatment equipment, its excellent performance and unique design provide a wide range of high-speed steel, die steel, stainless steel, alloy steel, titanium alloy and other alloy materials of high-precision parts of vacuum bright gas quenching, annealing, sintering of magnetic materials and rapid cooling and other characteristics. The vacuum quenching furnace consists of a heated hood and a mobile base frame. A crane is mounted on the top of the square (or round) hood, which lifts the basket to the furnace chamber by means of a chain and hook.

The hood is supported by section steel and has a pneumatically (or electrically) operated door at the bottom. The base frame, located under the hood, can be moved and positioned along the track, and the base frame is loaded with quenching water tanks and baskets. During production, move the basket on the base frame directly below the hood, open the furnace door, put down the chain and hook to lift the basket into the furnace chamber, close the furnace door and heat it.

To quench the ground, first move the sink on the base frame directly below the hood, then open the furnace door, lower the chain, and quench the basket (workpiece) into the water.

Vacuum quenching furnace is one of the commonly used quenching equipment in modern industrial production, which is mainly used for quenching metal or alloy materials to improve their hardness and wear resistance. The length of its service life is affected by a variety of factors, such as material, dust and structure, design, etc.

Normally, the service life of a vacuum quenching furnace is related to the warranty period provided by its manufacturer, which is generally around 3-5 years. But if there is good maintenance and upkeep during normal use, the service life can be longer. During use, attention should be paid to the regular cleaning and maintenance of the furnace body to keep it running normally.

In addition, other measures can be taken, such as installing temperature sensors, temperature controllers, vacuum level controls, etc., to ensure precise control and monitoring of the equipment.

In short, the service life of the vacuum quenching furnace is determined by the warranty period provided by the manufacturer and the maintenance of the user. If you can do regular maintenance and maintenance work, you can effectively extend its service life.

The service life can be up to 30 years. Pre-fang measures: When arc welding, the welding anti-spoiling strip should be slightly stopped at the weld pool or used as an annular coincidence moving belt.

Once the molten metal is filled, it will be directed to one side to extinguish the arc. When tungsten TIG welding is required, there should be enough time. After filling the weld, the residence time will attenuate the holding tremor arc.

Processing conversion of six types of stainless steel pipe fittings: The pre value of duplex stainless steel is about the same. And their resistance to pitting and crevice corrosion is also.

A vacuum quenching furnace is a kind of high-temperature processing equipment, and its service life can be affected by a variety of factors, so it is not possible to give a clear service life range. Here are some of the factors that can affect the service life of a vacuum quenching furnace:

1.Material quality: The quality and selection of materials in the vacuum quenching furnace are directly related to its service life. Vacuum quenching furnaces made of high-quality, heat-resistant steel or other alloying materials typically last longer.

2.Operation mode: Correct and reasonable operation mode can prolong the life of the vacuum quenching furnace. Long-term over-baking, carburizing and nitriding time for too long, improper use, etc., will cause damage to the furnace body.

3.Maintenance: Regular maintenance and maintenance can make the vacuum quenching furnace better perform and prolong its life.

4.Adaptation to the environment: Appropriate environmental conditions also have an impact on the life of the vacuum quenching furnace. For example, high-temperature, low-humidity environments can easily lead to corrosion and damage to boiler components.

In conclusion, the service life of a vacuum quenching furnace is affected by a number of factors, so it is not possible to give a definite service life range. Generally speaking, proper use and reasonable maintenance can greatly extend its service life and improve the performance and efficiency of the equipment.

High-pressure gas --- nitrogen are used for cooling to achieve quenching purposes.

This depends on the heating rod in the vacuum atmosphere furnace, if the temperature in the furnace is higher than the specified bright temperature, the gas will react with the heating rod and damage the heating rod Under normal circumstances, the temperature of the furnace is 50 200 degrees lower than the temperature of the element, the higher the temperature, the lower the temperature difference. Take silicon-molybdenum rods as an example. Nitrogen is 137, hydrogen at zero is 120, 0 degrees in vacuum is 1000 to 1200 degrees, and air is 1600 degrees.

Vacuum quenching furnace can not reach the vacuum degree: it may be that the pumping capacity of the vacuum unit is not enough, or it may be that the leakage rate is high, or both, after the vacuum chamber is pumped to a certain vacuum state, close the vacuum valve, if the vacuum counting value rises quickly, most of the cases are vacuum chamber leakage, then the leakage point should be found out and the leakage should be treated. If the vacuum counting value rises very slowly, it may be that the pumping capacity of the vacuum unit is not enough, and the focus is on finding the leakage of the vacuum pump and valve, or the vacuum pump oil is polluted and oxidized, or the pre-pipeline is not well sealed, the pump oil is insufficient, or the pump oil is emulsified, the shaft seal is leaking, etc., then the vacuum pump oil should be replaced or the vacuum pump should be replaced directly.

If the vacuum level of the equipment drops rapidly in a short period of time, it is generally caused by the aging, scratching and oxide scale falling off the sealing line of the dynamic seals such as furnace doors, vacuum valves, and intermediate interval hot spots. If there is no problem, then check the position of the interface between the vacuum chamber and the outside world, such as the connecting flange, water-cooled electrode, pipe and vacuum tube, etc., and sometimes the acetone leak detection method can be used to observe the change of vacuum degree and carefully find the leak point. If you can't find the leakage, you need to dismantle and reinstall all the suspected air leaks, or process the solid flange to block it and conduct a test.

Solution annealing: 17-4 stainless steel is heated to a temperature range of about 1010-1065°C, and kept warm for a period of time to dissolve the alloying elements in the crystal stool chain structure in a solid solution. 2.

Water quenching: Heats stainless steel is rapidly cooled to room temperature to avoid the formation of excessive precipitated phases after solution treatment. 3.

Precipitation hardening: The solution-treated stainless steel is heated to about the final hardening temperature, generally between 900-1150 °C, and kept warm for a period of time to form the precipitated phase in the solid solution. 4.

Air cooling: The tempered stainless steel is removed from the high temperature and then naturally cooled until room temperature.
