Why Should Choose Induction Heating Technology for Part Hardening and Tempering Process?

In the industry, the parts usually need to be heat-treated in order to be adapted to the working conditions. After heat treatment, the parts microstructure, hardness, tensile strength, yield strength will greatly improved. Therefore, heat treatment is a critical process during parts processing.

Heat treatment can includes hardening, tempering, annealing, normalizing etc, which will be applied to the manufacturing process as per different working condition requirements. Here we will talk about what equipment can be used for hardening and tempering process. Compared with conventional method, induction heating technology has many advantages for the heat treatment process of hardening and tempering.

Induction heating provides many advantages for manufacturing processes because it is a fast, energy-saving, flameless method of heating conductive materials. Typical systems include inductive power supply, inductor with copper coil and cooler or cooling unit. The current flows through the coil to produce an electromagnetic alternating magnetic field. When the conductive parts are placed inside the coil, there will be electric current passing through. The electric current is combined with the resistance characteristic of the conductive part to generate heat.

Then what is the benefit of induction heating for hardening and tempering of steel?

1.Flexibility

Induction heating system doesn't need preheating time and show-down time for the machines, then you can start or stop the machine as per your production need.

In most of case, the material in different size and grade must be tempered at different tempering temperature. But the conventional machines is hard to achieve temperature adjustment. If the bars or tubes are heated at the high temperature for a long period, the steel will be decarbonizing. On the contrary, induction heating system achieve different temperature adjustment, which is controlled by power output. This is very important for reaching different grade need of different grade bars or tubes.

2.Uniformity in hardness and structure

The steel microstructure will have following changes with the heat treatment process: Ferrite-Austenite- Martensite, Sorbide. But only the steel get homogeneous heating and cooling, then the structure can be changed homogeneously. If it can not transformed completely, then the hardness, toughness and tensile strength will be effected, thus leading that the material can not meet the actual application requirement. In the induction heating system, all the heating temperature will be monitored and controlled, so the structure will be transformed well and maintain stable state.

3.Very small maintenance

Compare the traditional furnaces, induction heating furnace only need to maintain the induction heating coil per year. Other parts only need to be regularly checked.

What Might Be Next In The Economy?

Since, we don't have a crystal ball, it is impossible to predict, accurately, the future! This is especially true, when, it comes to economic issues, including investment, real estate, interest rates, inflationary pressures, government actions, international factors, etc. What are the ramifications of inflation, recession, interest rates, Federal Reserve Bank decisions, etc? How can one, hedge - his - bet, in order to minimize unnecessary risks, while receiving a quality return, also? There is no simple answer, because so many factors, have significant influences. With, that in mind, this article will attempt to briefly, consider, examine and review potential factors, in order to help readers, have a more - complete understanding of the possibilities.

1) Interest rates: We have experienced a prolonged period of historically - low - interest rates. This has created easy money, because the cost of borrowing is so low. Both individuals and corporations have benefited, at least, in the immediate- term, permitting home buyers to purchase more house, because their monthly charges, are low, due to low mortgage rates. Corporate and government bonds, and banks, have paid low returns. It has stemmed, inflation, and created a rise in home prices, we haven't witnessed, in recent memory. The Federal Reserve Bank has signaled they will be ending this propping - up, and will also raise rates, probably three times, in 2022. What do you think that will cause.

2) Auto loans, consumer loans, borrowing: The auto industry has been, significantly, impacted by supply chain challenges. When rates rise, auto loans and leases, will be more costly.

3) THis pattern began after the Tax Reform legislation, passed at the end of 2017, which created the initial, new, trillion dollars deficits
