120kw Petroleum Pipelines quenching hardening induction heating machine
1. Quenching and heat treatment of ring gear in intermediate
frequency heating furnace
Walking wheels are used to support the weight of tractors and
agricultural implements, and to ensure that the machines run along
the ground. During the working process, the walking wheel has to
bear huge friction force. For this reason, we often use medium
frequency induction heating machine for quenching heat treatment to
improve the hardness, wear resistance and service life of the
walking wheel, and the effect is very good.
Medium frequency induction heating machine is generally used for
quenching heat treatment of workpieces with deep quenching depth.
When it performs quenching heat treatment on the walking wheel, the
heating speed is very fast, which effectively avoids the phenomenon
of oxidation and decarburization of the walking wheel during the
quenching process, ensures the quenching effect of the walking
wheel, and makes the hardened surface of the walking wheel after
quenching. The thicker ductile area has better compressive internal
stress, which makes the fatigue resistance and breaking capacity of
the road wheel higher. What's better is that it can carry out local
quenching heat treatment on the traveling wheel, and can also carry
out overall quenching heat treatment, which can meet the heating
requirements of different customers.

4. Application Ranges:Heat Treatment like annealing, normalizing, hardening/quenching,
tempering.
The important mechanical parts in the petrochemical industry are
mostly high-temperature, high-pressure, and pipelines that
transport corrosive media. They are used to transport crude oil,
dry gas, gasoline and other products. Because the media transported
inside the pipeline are all corrosive, so The toughness and
corrosion resistance of oil pipeline pipes should be improved.
The heat treatment process of oil pipelines is heat treatment by
high-frequency induction heating equipment, and the purpose of heat
treatment is to eliminate residual stress, improve the structure,
improve the comprehensive mechanical properties of the pipeline,
and ensure that the oil pipeline has sufficient strength, toughness
and corrosion resistance. The heat treatment of the pipeline by
high-frequency induction heating equipment not only improves its
corrosion resistance, but also prevents its brittleness and reduces
the quenched non-martensite and its transformation products.
Quenching can eliminate the rolling deformation and heating process
of the pipeline. The residual stress of the stroke, the heating
speed is fast, and the probability of oxidation and deformation of
the pipe during quenching is reduced.
