Low pressure vacuum carburizing (including carbonitriding) series equipment mainly includes seven categories: 1.1 horizontal double chamber oil quenching type, 1.2 vertical double chamber oil quenching type, 1.3 horizontal double chamber gas quenching type, 1.4 horizontal single chamber gas quenching type, 1.5 vertical single chamber gas quenching type, 1.6 horizontal three chamber salt bath type, and 1.7 vertical double chamber salt bath type;
Main purposes of low-pressure vacuum carburizing (including carbonitriding) furnace:
It is applicable to various carburizing or carbonitriding products or parts with high added value and high treatment quality requirements, such as low pressure vacuum carburizing, carbonitriding and quenching of gear, gear shaft and other parts; And vacuum quenching and vacuum annealing of high-speed steel, tool and die steel, alloy structural steel, etc.
Main advantages of low-pressure vacuum carburizing (including carbonitriding) furnace:
Safety and environmental protection, no open fire, no explosion hazard;
Good production flexibility, can stop and open the furnace at any time;
There is little internal oxidation in the carburizing layer, and the performance of the carburizing layer is high;
Especially suitable for blind hole carburizing of fuel injection nozzle parts, and the carburizing layer is uniform;
The carburizing temperature can reach 1050 ℃, which is used for stainless steel carburizing and deep carburizing;
The workpiece surface quality is good, and the quenching deformation is small;
Low carburizing atmosphere consumption, short carburizing cycle and low production cost;
Low equipment maintenance cost.
Process control of low-pressure vacuum carburizing (including carbonitriding) furnace:
The process program inventory stores the carburizing process program generated in advance by the process simulation system according to the material composition, carburizing temperature, carburizing layer depth and surface carbon content and verified by production practice; The control system automatically and accurately controls the carburizing temperature, carburizing pressure, carburizing gas flow and pulse carburizing time sequence according to the program to ensure that the requirements of carburizing or carbonitriding process are met.
Low pressure vacuum carburizing (including carbonitriding) production line:
A charging car system outside the furnace can be configured to form a production line with multiple low-pressure vacuum carburizing (including carbonitriding) furnaces, vacuum tempering furnaces, various cleaning machines and other equipment to meet the production needs of large-scale low-pressure vacuum carburizing or carbonitriding.

The low pressure vacuum carburizing (including carbonitriding) series equipment takes the category "1.1 horizontal double chamber oil quenching type" as an example to list the main parameters of its current standard model equipment

Note:
1. The above are the parameters of our standard equipment. Shenyang Dongbo can carry out non-standard design and manufacturing according to the specific requirements of customers to meet the customer's personalized needs. For example, the extreme vacuum degree can reach 10-4Pa or above;
2. The limit vacuum degree of equipment with two or more chambers refers to its heating chamber; The following tables are the same and will not be repeated;
3. Timing starting point of workpiece transfer time for equipment with two or more chambers: workpiece moves from the heating chamber; The following tables are the same and will not be repeated;
4. Pressure refers to absolute pressure, which will not be repeated;
5. All our products are vacuum thermal equipment, which has all the advantages of vacuum thermal equipment;
6. According to the user's needs, the equipment can meet the requirements of different standards, such as HB5425, AMS2750, etc., which will not be repeated.
