Abstract
The invention discloses an evanescent mode casting hammerhead which comprises the following chemical components by weight percent: 3.2%-4% of C, 0.9%-1.4% of Si, 1.0%-1.5% Mn, 11.4%-12.8% Cr, 0.31%-0.36% of Mo, 0.08%-0.14% of Cu, 0.07%-0.16% of V, 0.010%-0.020% of Nb, 0.03%-0.045% of Ti, 0.02%-0.05% of W, 0.02%-0.05% of B, 0.05%-0.08% of Ce, and the balance being Fe. According to the evanescent mode casting hammerhead of a high-strength crusher, on the basis of a high-chromium alloy, a manganese element is additionally added, so that the hardness is improved effectively, the wear-resisting property is more superior than those of a hard alloy hammerhead and a high-chromium alloy hammerhead at present, and the service life is longer.
Description
Technical field
The present invention relates to a kind of lost foam casting tup.
Background technology
Lost foam casting is a kind of almost without the novel process of surplus, precise forming, and this technique is without the need to delivery, without joint face, without core, and thus foundry goods does not have overlap, burr and pattern draft, and decreases the scale error caused due to core combination.Surface roughness can reach Ra3.2 to 12.5 μm; Casting dimension accuracy can reach CT7 to 9; Process redundancy mostly is 1.5 to 2mm most, can greatly reduce the expense of mechanical workout, compares with traditional sand mould casting method, can reduce by the machining amount of 40% to 50%.But, utilize the tup of lost foam casting to be difficult to ensure the wear resisting property required for tup and requirement of strength.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides the lost foam casting tup of a kind of Gao Ge, manganese steel material.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of lost foam casting tup, comprises following chemical composition, the percent by weight pressed:
C 3.2%-4%, Si 0.9%-1.4%, Mn 1.0%-1.5%, Cr 11.4%-12.8%, Mo 0.31%-0.36%, Cu 0.08%-0.14%, V 0.07%-0.16%, Nb 0.010%-0.020%, Ti 0.03%-0.045%, W 0.02%-0.05%, B 0.02%-0.05%, Ce 0.05%-0.08%, all the other are Fe.
Preferably, above-mentioned high strength grinder hammerhead, comprises following chemical composition, the percent by weight pressed:
C 3.8%, Si 1.1%, Mn 1.2%, Cr 12.0%, Mo 0.35%, Cu 0.12%, V 0.12%, Nb 0.018%, Ti 0.04%, W 0.04%, B 0.04%, Ce 0.06%, all the other are Fe.
Lost foam casting tup provided by the invention, on the basis of Gao Ge, with the addition of manganese element more, hardness obtains effective lifting, the hard alloy hammer that wear resisting property is more current and high-chromium alloy tup all more superior, wear resisting property is guaranteed, and longer service life is of a specified duration.
