What are the kinds of controlled atmosphere heat treatment furnace

Controlled atmosphere heat treatment furnace, depending on the assignment form can be divided into two categories, cycle type and continuous type, and in two categories according to different ways of furnace type structure and movement is divided into the following categories: periodic furnace, such as the sealed box furnace, multi-purpose furnace) and pit type furnace, etc., applicable to many varieties of small batch production, can be used for the bright quenching, bright annealing, carburizing and carbonitriding heat treatment. Continuous furnace, such as push rod furnace, rotary hearth furnace and continuous type controlled atmosphere carburizing production line, such as use of mass production, can be bright quenching, tempering, carburizing and carbonitriding heat treatment, etc.
The basic structure of the controlled atmosphere heat treatment furnace and general heat treatment furnace is basically the same, its design and calculation method and general heat treatment furnace is also the same. Single due to access to controlled atmosphere in the furnace, and therefore should have some special requirements in the structure, in the aggregate, has the following nine aspects: 1. The chamber of a stove or furnace sealing; 2. Maintain positive pressure in the furnace; 3. Uniform furnace atmosphere; 4. The use of carburizing brick; 5. Use appropriate heating elements; 6. Set the ventilation exhaust system; 7. Set the former room, room, after quenching tank and furnace sealing; Mechanical front-rear device; 8. 9. Set safety explosion-proof device;
