The present invention relates to mine mechanism technical fields, more particularly to a kind of manufacturing method of mining machinery axle.
Background technique
In the prior art, mining machinery axle casting mostly uses greatly sand casting mode to complete, due to the use of mining machinery
Environment is more severe, so using axle made of sand casting mode, in use, there are of poor quality, strong on mine mechanism
Defect low, that precision is low is spent, and inconvenient during fabrication, and die life is short.
Summary of the invention
In order to solve the above technical problems, a kind of manufacturing method of mining machinery axle is provided, it is specific as follows:
A kind of manufacturing method of mining machinery axle, comprises the following steps that:
(1) metal-molding is standby: preparing metal die using machining or casting and forming, and to mould after the completion of mold manufacture
The working face of tool carries out ball blast and blasting treatment, is finally polished with using polissoir, finally carries out at tempering and annealing
Reason；
(2) it smelts: molten steel being smelted using AOD refining furnace, pull dross out in time, P≤0.03% in molten steel, S≤
0.035%, smelting temperature is not less than 1400 DEG C, smelts and is transferred in middle ladle in completing for use, middle ladle carries heating system；
(3) it is poured: molten steel being prolonged into metal mold and is poured into, personnel are separate when pouring, and eliminated in molten steel by ultrasonic oscillation
Gas；
(4) solution treatment: being first air-cooled to 1100-1200 degrees Celsius after the completion of pouring, and is then as cold as 600-700 using oil and takes the photograph
Family name's degree, last direct-water-quenching；
(5) it cleans: after being cooled to room temperature, being cleaned using high pressure water brass tumbler；
(6) it polishes: after the workpiece for pouring acquisition is cleaned, then carrying out surface polishing.
As the further scheme of the present invention: tempering temperature is 500-600 degrees Celsius in the step (1), the temperature of annealing
It is 80-12 degrees Celsius, and is carried out in protective atmosphere.
As the further scheme of the present invention, adjustment temperature is adjusted to 1600 after vacuum refining in step (1) the AOD refining
Between DEG C -1650 DEG C, by obtaining the molten steel of the high-quality qualification of composition with the accurate analysis of spectrum.
Compared with prior art, the beneficial effects of the present invention are:
Present invention process is simple, easy to operate, manufactured mining machinery axle casting, good mechanical property, and metal
Die life is long.
Specific embodiment
The present invention will be further described below, but protection scope of the present invention be not limited to it is as described below.
A kind of manufacturing method of mining machinery axle, comprises the following steps that:
(1) metal-molding is standby: preparing metal die using machining or casting and forming, and to mould after the completion of mold manufacture
The working face of tool carries out ball blast and blasting treatment, is finally polished with using polissoir, finally carries out at tempering and annealing
Reason；
(2) it smelts: molten steel being smelted using AOD refining furnace, pull dross out in time, P≤0.03% in molten steel, S≤
0.035%, smelting temperature is not less than 1400 DEG C, smelts and is transferred in middle ladle in completing for use, middle ladle carries heating system；
(3) it is poured: molten steel being prolonged into metal mold and is poured into, personnel are separate when pouring, and eliminated in molten steel by ultrasonic oscillation
