Why choose induction heating?
INDUCTION HEATER WITH STATIC FREQUENCY CONVERTER
- Presence only of electric power with adequate control systems and high security.
- No flame. The point at higher temperature is the material in heating thanks to the physics of the induction heating, that allows the heating of the material by induced currents.
- Very low presence of oxidation of the material, moreover, with the possibility of increasing their quality by blowing nitrogen in the heating coil.
- Then absence of slag ensuring high quality of the heated material to further processing and longer life of the molds.
- No need to preignition and start of production in a very short time.
- Easy maintenance with on and off the system in a few moments.
- Plants stop limited.
- Capacity for adjusting the heating temperature of the pieces in quickly and directly.
- Short heating time, each piece remains in heating for a short time (that is sufficient for the heart of the material to get the desired temperature) avoiding oxidation and decarburization.
- Installation of compact size with limited space requirements.
- Plant outer limited to the system of water cooling and the source of electrical energy.
- Complexity of the machine with electronic technology inside.
- Need for adequate electrical distribution system.
- Risks of melting of the material if serious errors are committed in the settings parameters of heating or under conditions of forced manual controls by the operator.
- Of common use of billets or bars with regular shape round or square for best mate inductor heating.
FURNACE ROOM NATURAL GAS POWERED
- Absence of accidental overtemperature of the material in heating since the temperature of the heating chamber is limited, although to get good results in terms of final temperature of heating times it is necessary to keep the temperature in the chamber higher than necessary.
- Uniformity of temperature on condition that the material will remain inside of the room a time necessary to make the material’s temperature homogeneous at the expense of considerable consumption of energy, and lower productions and presence of oxidation of the material.
- It can use for special forms non-homogeneous, as some already forged with the need for a subsequent process or irregularly shaped.
- Hazard in the use of natural gas, with strict safety rules and danger of explosion chamber saturated with gas.
- High consumption of oxygen and pollution in the surrounding air.Presence of flame.
- Strong oxidation of the material in heating, with effect of slag surface of the workpiece and internal oxidation, due to the combustion of methane gas (fuel) and oxygen (oxidizing) inside the chamber where the material passes through or is parked.
- Poor quality of the molding material due to oxidation and slag.Increased wear of the molds of presses or hammers due to the presence of more waste.
- Loss of weight of the material significantly and poor surface quality.
- Slow response to changes in temperature set.Need to preignition to get the correct temperature of the room at the beginning of production.
- Need for time-outs and consequent difficulty of maintenance of the furnace due to an area with high temperature cooling requirements over the long term.
- Slowness in the heating resulting from the mere presence of thermal convection and radiation between room and material, which leads to the increase of the slag and oxidation having heating times more.
- It also entails a considerable length of the tunnel reheating with more space and use of spaces.Worst working conditions of the operator near the furnace chamber due to the glare of the hot spots.
The many benefits of using an induction heater, especially in hot forging, hardening, pipes coating, the fusion of precious metals, led the entire market to prefer this type of technology for the thermal increase of the workpieces.
From this short list can be seen as the induction heating will present more compact, more versatile, more economical, simpler and easier maintenance than the application of a gas oven, making it technologically advanced in many thermal processes.
