heat treatment furnace Introduction

 heat treatment furnace Introduction ：A general term for industrial furnaces that carry out various metal heat treatments on metal workpieces.The temperature is generally lower than that of the heating furnace. The heat treatment furnace can adopt various types of heating furnaces, but strict control of the furnace temperature and atmosphere in the furnace is required. The heat treatment furnace can be heated with gas fuel. In order to accurately control the furnace temperature, some heat treatment furnaces are heated with electricity. Modern heat treatment (especially chemical heat treatment) processes are becoming increasingly complex, and there are many forms of heat treatment furnaces. For a continuous heat treatment process, a suitable continuous heat treatment furnace must be equipped; for a periodic heat treatment process, a forced circulation controlled atmosphere must be used to mechanize and automate the operation of the furnace. Do you want to know about the heat treatment furnace? Then let us understand the classification, principles and characteristics of heat treatment furnaces.

The working principle of heat treatment furnace:

The heat treatment furnace adopts the principles of convection and radiation heating. The workpiece is placed into the furnace. When the gas passes through the burner  mouth, heat is released into the furnace, so that the furnace body and the workpiece are heated. The flame ejected from the burner mouth or the electric heating element conducts convection transfer to the workpiece. Heat or thermal radiation achieves heating of the workpiece.

Heat treatment furnaces are roughly classified:

Heat treatment furnaces are divided into two types, periodic type and continuous type in terms of heating methods.

Periodic heat treatment furnace: Place one batch of charge at a time, and then put down another batch of cold charge after the heating is completed. Continuous heat treatment furnace: There are multiple charges in the furnace at the same time. When a new charge is fed into the inlet end, a hot charge that meets the temperature requirements is given out at the outlet end and heated in a certain rhythm sequence. It completes continuous production by pushing the cold billet into the furnace through a hydraulic push rod or a movable furnace bottom installed at the charging end of the furnace, and then ejecting the heated billet from the discharge end. Heat treatment furnaces are divided into two types: gas heating and electric heating in terms of combustion methods. Gas heating is divided into regenerative heating and conventional heating:

Heat treatment furnaces are divided into two types: gas heating and electric heating in terms of combustion methods. Gas heating is divided into regenerative heating and conventional heating:

Gas heat treatment furnace regenerative heating. This type of furnace burners appear in pairs. One burner burns and brings the heat in the regenerator into the furnace to participate in combustion. The other burner exhausts smoke and stores the heat of the flue gas in the furnace. Heat storage in the body. Periodic reversal work. The regenerative heating furnace can heat the combustion air to above 1000°C, saving 50% energy.The heat treatment furnace is conventionally heated and uses a conventional burner to form a flame. The heat in the flue gas is converted into the heat of the combustion air through a heat exchanger. The combustion air can be preheated to about 350°C, saving 20% ​​energy.Heat treatment furnaces are divided into chamber heat treatment furnaces, trolley heat treatment furnaces, and roller hearth heat treatment furnaces in terms of loading form.
