Mould, wax-pattern need cryo-conservation；
(2) mould is moved back, will be taken out from wax injector in the consistent wax-pattern of mining machinery axle casting, while using fluorescer pair
Wax-pattern is once sprayed, and realizes label；
(3) form sand mold: the sand mold after wax-pattern is wrapped up and dried using molding sand then takes out wax-pattern, by sand mold
Phosphor layer on cavity wall judges the acceptable level of sand mold, i.e., should be caught one layer on its interior cavity wall of the sand mold of qualification
Even fluorescent paint；
(4) it roasts: qualified sand mold being roasted, 600-800 degrees Celsius of maturing temperature, 12 hours of calcining time,
Enclosed burning kiln is needed after fire is closed in roasting, keeps the temperature 6-8 hours；
(5) it smelts: molten steel being smelted using AOD refining furnace, molten steel will timely understand dross, P in molten steel≤
0.030%, S≤0.02%, smelting temperature are not less than 1300 DEG C, and molten steel is transferred in ladle before then pouring；
(6) it is poured: sand mold being embedded in casting sand pit, molten steel is prolonged into sand mold and is poured into；
(7) it solution treatment: first air-cooled to 1000-1100 degrees Celsius, is then sent directly into 60-80 degrees Celsius of oil and carries out
Oil quenching, band temperature are taken out after stablizing；
(8) it cleans: after being cooled to room temperature, being cleaned using high pressure water brass tumbler, and realize that surface is de- using dehydrogenating agent
Hydrogen；
(9) it clears up: impeller blasting is carried out to casting using shot-blast cleaning machine.
As a further solution of the present invention: wax injector carries temperature control system in the step (1), wax material after forming and
When low temperature, be easy to form preservation.
As a further solution of the present invention: the step (7) is quenched and is tempered, and is alternately repeated 2-3 times.
Compared with prior art, easy to operate the beneficial effects of the present invention are: present invention process is simple, it is manufactured
Mining machinery axle casting has crystalline grain of steel tiny, the high advantage of intensity, plasticity, toughness, it can be ensured that the operation of mining machinery
Safety requirements.
