Abstract
The invention discloses a heat treatment technology of a rear axle housing. In the deoxygenation process, aluminum is adopted to serve as a deoxidizing agent, and the amount of deoxidizing agent is 0.1% to 0.15% of the weight of molten steel; and after deoxidizing, standing is carried out for 2 minutes to 3 minutes, so that a deoxidizing product can float upwards. According to the heat treatment technology of the rear axle housing, the aluminum is adopted to serve as the deoxidizing agent, the hardness of a final material is larger, and the toughness is stronger.
Description
Technical field
The present invention relates to a kind of rear axle housing body thermal treatment process.
Background technology
The quality of design to casting quality of casting technique plays a part crux.The rear axle housing of wheel excavator is the important security part of excavator.It subjects the Moment of heavier load and constantly change in excavator travels, and easily occur curved allusion quotation repeated stress failure phenomenon, therefore, rear axle housing should have good rigidity and fatigue resistance performance.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of rear axle housing body thermal treatment process.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of rear axle housing body thermal treatment process, during deoxidation, employing aluminium is reductor, and add-on is 0.1% ~ 0.15% of Metal Weight, should leave standstill 2-3 minute after deoxidation, and deoxidation products is floated.
Preferably, the add-on of described aluminium is 0.12% of Metal Weight.
Beneficial effect of the present invention:
Rear axle housing body thermal treatment process of the present invention, adopts aluminium as reductor, and make final material hardness larger, toughness is stronger.
