Classification and description of heat treatment furnace

Firstly, the structure of the thermocouple, which is the key component of the temperature in the vacuum heat treatment furnace (0 ~ 1300 ℃), and the type, advantages and disadvantages of the thermocouple in the vacuum heat treatment furnace are introduced. Then, the types, selection methods and cost performance of thermocouples used in this furnace are summarized. The differences between the thermocouples used in foreign vacuum heat treatment furnaces and domestic ones are compared. Finally, the types of thermocouple protection tubes and their application in vacuum heat treatment furnace are introduced. Through the analysis, we can have a deeper understanding of thermocouples. In the production application, we can choose the right thermocouple according to the actual situation, which can save the production cost for the enterprise.

Classification and description of heat treatment furnace

Heat treatment furnace is one of the important process equipment in mechanical manufacturing. It is mainly a treatment equipment that heats the metal workpiece in a certain medium to a suitable temperature, and maintains it for a certain time in this temperature, and then cools it at different speeds. It is mainly a kind of heat treatment equipment which is used for annealing, tempering, quenching and heating of workpieces.

Product classification:

1. Bell type furnace: a periodic heat treatment furnace in which the heated substance is heated in the hood.

2. Roller hearth furnace: it is used to transport heat-treatment materials by roller in the furnace. The furnace above and below the roller can be equipped with burners for heating.

3. Chain furnace: a conveyor belt type heat treatment furnace.

4. Traction type heat treatment furnace: the traction type furnace is generally divided into horizontal and vertical type, which is widely used in the continuous heat treatment furnace of tin plating, zinc plating, silicon steel and stainless steel for cold rolling strip.

5. Steel wire lead quenching furnace: it is a kind of traction type heat treatment furnace, which is used for heating steel wire before isothermal quenching in lead tank.
