Induction Heat Treatment Process

With 6 induction heat treating machines, we soften or harden metal through targeted heating, hardening, tempering, or annealing. We specialise in induction heat treating a range of metal parts, such as drive shafts, bearings, axle shafts, camshafts, and sprockets.

Induction Annealing for Metals

Our induction heat treatment process is best suited for enhancing the ductility of steel, stainless steel, and carbon steel parts without compromising on the dimensional stability of the materials. In addition, our induction heating process is environmentally friendly and offers higher heating intensity compared to conventional metal treatment techniques.

Induction Hardening Capabilities

Factors such as electrical properties of pieces, the coupling efficiency of coils, and the degree of temperature change required are taken into consideration during induction heat treatment. Our Zion Z scan induction heat treated features a 6 position rotary index table and easy-to-maintain hydraulics. The Zion Z scan induction heat treated is capable of heat treating pieces with diameters up to 1 1/4" and lengths up to 20".

Air & Fuel Oil Coolers - Turbine Lubrication System Components

Air Oil Coolers

Two basic types of oil coolers in general use are the air-cooled and the fuel-cooled. Air oil coolers are used in the lubricating systems of some turbine engines to reduce the temperature of the oil to a degree suitable for re-circulation through the system. The air-cooled oil cooler is normally installed at the forward end of the engine. It is similar in construction and operation to the air-cooled cooler used on reciprocating engines. An air oil cooler is usually included in a dry-sump oil system. This cooler may be air-cooled or fuel-cooled and many engines use both. Dry- sump lubrication systems require coolers for several reasons. First, air cooling of bearings by using compressor bleed-air is not sufficient to cool the turbine bearing cavities because of the heat present in area of the turbine bearings. Second, the large turbofan engines normally require a greater number of bearings, which means that more heat is transferred to the oil. Consequently, the oil coolers are the only means of dissipating the oil heat.

Fuel Oil Coolers  

         

The fuel-cooled oil cooler acts as a fuel oil heat exchanger in that the fuel cools the hot oil and the oil heats the fuel for combustion. Fuel flowing to the engine must pass through the heat exchanger; however, there is a thermostatic valve that controls the oil flow, and the oil may bypass the cooler if no cooling is needed. The fuel/oil heat exchanger consists of a series of joined tubes with an inlet and outlet port. The oil enters the inlet port, moves around the fuel tubes, and goes out the oil outlet port.
