Abstract

The invention provides a 60Si2Mn steel spring heat treatment method. The method comprises the following steps: heating a steel spring to 930DEG C, measuring the heat variable of the steel spring, heating to 930DEG C+18% of the heat variable, and carrying out high temperature rapid tempering adopting a tempering temperature of 650DEG C and a heat insulation time of 3.25min. The 60Si2Mn steel spring heat treatment method greatly improves the strength and greatly prolongs the fatigue life.

Description

A kind of 60Si2Mn steel spring heat treating method
Technical field
The present invention relates to a kind of 60Si2Mn steel spring heat treating method, belong to machinery manufacturing technology field.
Background technology
60Si2Mn steel spring heat treating method is generally preheating, heating, insulation, cooling, tempering insulation, cooling, the quenching temperature of spring steel is generally 860 degrees centigrade, if temperature and soaking time control bad, the consequence finally caused is that ferrite can not dissolve completely.And the thermal stresses occurred when quenching also just is eliminated in tempering, affect quality and the life-span of spring.
Summary of the invention
The invention provides a kind of 60Si2Mn steel spring heat treating method, the above defect can be overcome.
For solving above technical problem, the invention provides following technical scheme: a kind of 60Si2Mn steel spring heat treating method, steel spring is heated to 930 DEG C, measure the hot variable of steel spring, again steel spring is heated to 930 DEG C+hot variable 18%, adopt tempering temperature to be 650 DEG C, soaking time is the high temperature and fast temper of 3.25min.
This 60Si2Mn steel spring heat treating method that the present invention relates to is a kind of deformation heat treatment method, is combined with heat treatment reinforcement by the deformation strengthening of steel, improves intensity and the toughness of steel further.Thermomechanical treatment has dividing of high temperature, middle gentle low temperature.High-temperature particles quenches immediately produce deformation under stable austenitic state after, also can combine with forging or hot rolling, namely quench immediately after thermoforming.Intensity and fatigue lifetime are all greatly improved.
Embodiment
A kind of 60Si2Mn steel spring heat treating method, steel spring is heated to 930 DEG C, measures the hot variable of steel spring, then steel spring is heated to 930 DEG C+hot variable 18%, adopt tempering temperature to be 650 DEG C, soaking time is the high temperature and fast temper of 3.25min.
