Product Description
Mining Machinery Replacement Parts and Equipment
Procedures:
(1)Process Design:Design the tooling according to customs' drawing or sample, set up the pouring system with CAE casting simulation software.
(2)Mould Fabrication:Transfer the drawing or sample into 3D drawing which is applied to aluminum or steel mould fabrication.
(3)Wax Injection:Mix liquid wax slurry and solid wax together, inject wax into metal mould, fetch it out after cooling.
(4)Wax Mold Assembly:Heat the stainless steel welding knife, weld the wax molds together on the gate stick according to technically designed.
(5)Dipping:The wax molds are dipped into waterglass solution, with surface coated by the solution.
(6)Stuccoing:Stucco the dipped wax molds with quartz sand, then dip into induration solution containing ammonium chloride & magnesium chloride and hang to dry. The whole process repeats 6 times.
(7)Wax Removal:Put the thick coated wax molds into wax removal gutter, keep heating. After lost all the wax only sand shell was left.
(8)Sand Shell Preheat:Heat the sand shell in order to strengthen the shell.
(9)Casting:Put the raw material into the induction furnace and melt, add with chemical composition per material spec. After the temperature of molten steel rises to about 1600 degrees, take a pre-pouring chemical analysis, if approved then pour liquid steel into the sand shell by ladle, make sure the shell is filled with liquid steel and then cool off, meanwhile take the testing bar for after-pouring analysis.
(10)Sand Shell Removal:Make the casting free from sand by shaking.
(11)Cutting:Oxyacetylene cut off the castings from gate stick.
(12)Grinding:Grind the ingate and defected surface with grinding wheel.
(13)Heat treatment:Heat treat the casting by nomalizing, annealing, quench+tempering, induction quenching, case hardening and Nitriding per material spec.
(14)Machining:Machine the castings by CNC according to drawing spec.
(15)Final inspection:Test the parts' mechanical properties by tension tester, impact tester, hardness tester, take NDT with X-ray, UT and M.P.T, final dimension inspection are down by CMM, Measures & Gauges, etc.
(16)Pack & Transport:After rust prevention, pack the parts into plywood or iron case for transportation.
For Investment Casting Process Concept:
Characteristics of casting:
The main advantages of precision casting are:
Choice of material.
Freedom in design.
Close tolerances
Fine surface finish.
Reduce costs
Investment casting also can be called "precise casting" or " lost wax casting" or "dewaxing casting". the casting materials can widely used, and no limitation for product shape as well as complex structure. The most important characteristic is the close tolerances control, reduced machining allowances, and fine surface finish. Its application scope can be wider after using the new equipment and advanced technology. In heat processing industry, investment casting can be used for those products which difficult to choice the materials, or materials not easy to form a shape, as well as some forging pieces with higher cost; while in the casting industry, the investment casting can be used instead of other casting methods, so as to reduce machining allowances and the cost, improve the dimensional precision and surface finish as well as the mechanical properties, so as to meet the requirements of a higher level product.
