Abstract
The utility model discloses a device for eliminating sesame flaws of a lost-wax fine-casting stainless steel part, which comprises a runner cup, wherein the bottom part of the runner cup is provided with an annular lug boss which can support a ceramic foam filter, and a filter is arranged inside the runner cup. The device has a simple structure, is convenient to use, and can effectively eliminate the sesame flaws of the lost-wax fine-casting stainless steel part.
Description
Technical field:
The utility model relates generally to smart casting field, relates in particular to a kind of device of eliminating investment pattern precision casting stainless steel part sesame point defect.
Background technology:
Austenite stainless steel plate shape foundry goods is erect pouring technology yield rate height, it is the casting technique of using always, but external diameter has the sesame spot defect after the foundry goods fine finishining of this cast, and the existing method that solves this kind defective is that smart casting wax will take off totally, wash with boiling water that shell, roasting are wanted fully, use clean steel material, melting fast, used special-purpose refining agent, intermediate frequency furnace cuts off the power supply and leaves standstill molten steel etc.These methods use back sesame spot defect ratio to descend to some extent jointly, but still reach more than 25%.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of device of eliminating investment pattern precision casting stainless steel part sesame point defect to be provided, and it is simple in structure, and is easy to prepare.
The utility model is achieved through the following technical solutions:
A kind of device of eliminating investment pattern precision casting stainless steel part sesame point defect is characterized in that: include cup, described cup bottom is provided with the annular boss that can hold filter, is placed with filter in the described cup.Filter is put into from the cup oral area, drops on the annular boss.
A kind of device of eliminating investment pattern precision casting stainless steel part sesame point defect is characterized in that: described filter is a ceramic foam filter.
During cast, molten steel is filtered in cup, and the molten steel that flows in the mold cavity is clean molten steel.The visual no sesame spot defect of machined surface of the investment pattern precision casting stainless steel part that processing obtains does not have other defect yet, and dye penetrating detects machined surface, also zero defect sign.
Advantage of the present utility model.
The utility model is simple in structure, and is easy to operate, can effectively eliminate sesame point defect on the investment pattern precision casting stainless steel part.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
A kind of device of eliminating investment pattern precision casting stainless steel part sesame point defect includes cup 1, and described cup 1 bottom is provided with the annular boss 3 that can hold ceramic foam filter, is placed with ceramic foam filter 2 in the described cup 1.During operation, cup is enclosed within on the rising head 5 of stainless cast steel part 4.
Claims (2)
