Special equipment for quenching mechanical parts in Heilongjiang looks for Chaofeng Chaofeng. It tells that the surface hardness of parts quenched by high-frequency induction heating equipment is lower than the technical requirements, which is called insufficient hardness. The hardness of local areas of the surface of parts processed by high-frequency quenching machines is lower than Technical requirements are called soft spots. Insufficient hardness and soft spots are also quality problems that often occur in high-frequency induction quenching. Generally, decarburization on the surface of parts is caused by the following factors
Surface decarburization and carbon depletion of parts are all induction quenching. The important reason for insufficient hardness is that the hardness of steel quenched by high-frequency machines is determined by the carbon content. The higher the carbon content, the higher the hardness of high-frequency quenching.
The common reasons for surface decarburization of induction quenched parts are There are two, one is decarbonization of raw materials, and the other is decarbonization of blanks during the heat treatment process of pre-medium frequency induction heating equipment.
Coarse grains and band-like structures in the material
Insufficient heating temperature of high-frequency induction heating equipment
Insufficient induction heating temperature of Heilongjiang special equipment for quenching mechanical parts is also caused by Chaofeng high-frequency quenching furnace. An important reason for insufficient surface hardness.
Why are the hardness of high-frequency induction quenching parts insufficient? Chaofeng explains that the reasons for the low induction heating temperature may be the following:
. The power of the high-frequency induction heating machine is small and the heating time is short
/>, The sensor gap is too large or the effective ring shape design is unreasonable
There is water in the sensor. When heated, the water flows out and adheres to the surface of the part, which reduces the quenching temperature there and forms soft spots after quenching. .
Insufficient cooling rate
The reasons for insufficient cooling rate of the high-frequency machine may be the following:
, quenching liquid injection pressure is too low
, quenching liquid flow rate is too small
The temperature of the quenching fluid is too high
The water hole of the sprinkler is blocked or choked. If a large water hole is blocked or choked, it may cause continuous soft spots.
