Analysis of Heat Treatment Technology for Crankshaft of Air Compressor

Today we will talk about heat treatment of air compressor crankshaft.

1. Intermediate frequency induction quenching of crankshaft

The crankshaft intermediate frequency induction quenching will adopt a microcomputer monitoring closed loop intermediate frequency induction heating device, which has the characteristics of high efficiency, stable quality, controllable operation, etc.

2. crankshaft soft nitriding

For crankshafts produced in large quantities, in order to improve product quality, a microcomputer-controlled nitrogen-based atmosphere gas soft nitriding production line will be adopted in the future. The nitrogen-based atmosphere gas soft nitriding production line consists of a front cleaning machine (cleaning and drying), a preheating furnace, a soft nitriding furnace, a cooling oil tank, a rear cleaning machine (cleaning and drying), a control system, a gas production and distribution system, and other systems.

3. crankshaft surface strengthening technology

Nodular cast iron crankshaft fillet rolling strengthening will be widely used in crankshaft processing. In addition, compound strengthening processes such as fillet rolling strengthening plus journal surface quenching will also be widely used in crankshaft processing. Forging steel crankshaft strengthening will be more processed by journal plus fillet quenching.

Xingchang Fan Company can produce all kinds of precision machined parts, especially crankshaft and pulley products.
