Description
Technical field
The utility model relates to vaccum sensitive stove casting field, refers to the online apparatus for baking of a kind of vaccum sensitive stove hot investment casting shell particularly.
Background technology
Vaccum sensitive stove is the important smelting equipment producing special steel, high temperature alloy, Precise Alloy, smelting carries out under the condition of negative pressure and isolated from atmosphere, complete the heating of furnace charge, fusing, refining, alloying and pouring technology successively, there is the chemical composition accurately controlled, the harm of less gas element, higher degree of purity, properties of product comparatively advantages of higher, be widely used in laboratory variety test and industrial production.At present, vaccum sensitive stove molten metal shaped device is the simple metal ingot mould of structure mainly, for some baroque precision castings, seldom be applied in vaccum sensitive stove and carry out hot investment casting, because the former of hot investment casting at present or complex process, if evaporative pattern precise manufacture is except needs manufacture evaporative pattern mold, need sandbox, the coordinative composition of equipments such as air exhauster, the wax-pattern shell of lost wax casting technique in hot investment casting, need after special oven is baked to 800 DEG C-1100 DEG C, by artificial or be mechanically retained to cast station, ladle or funnel is used to pour into a mould shell, then at coagulation forming.
Industrially carrying out hot investment casting and normally utilize intermediate frequency furnace melting, moulding by casting under air atmosphere, there is the harm such as air-breathing, oxygenation, burning loss of alloy in tapping and casting process; In vaccum sensitive stove, fusing and the same space casting in negative-pressure vacuum carry out, if hot investment casting shell after heating furnace baking, break sky at vaccum sensitive stove to pour into a mould, the same effect is smelted under causing air like this, therefore seriously limit the application of hot investment casting at vaccum sensitive stove, cause the market share of current vaccum sensitive stove direct production high-quality foundry goods little.At present, mainly comprise about Baking out equipment, combustion gas Baking out, resistance heated, induced-current heating etc., because features is applied to different field respectively; Generally undertaken toasting rear use by independent resistance furnace for hot investment casting shell is industrial, vaccum sensitive stove there is no supporting online baking equipment in the market.
Summary of the invention
The purpose of this utility model will provide a kind of vaccum sensitive stove hot investment casting shell online apparatus for baking exactly.
For achieving the above object, the online apparatus for baking of a kind of vaccum sensitive stove hot investment casting shell designed by the utility model, it is characterized in that: comprise the incubator that top is provided with shell accommodation hole, be provided with in described incubator for be baked shell heating barrel shape graphite-pipe, the both sides tube wall of described barrel shape graphite-pipe is respectively equipped with the accumbency L-type graphite block for conducting electricity, the outer wall of described incubator is provided with respectively for the through hole that two accumbency L-type graphite blocks pass through, one end of described two accumbency L-type graphite blocks is connected with barrel shape graphite-pipe, the other end is connected with wire through through hole, the glass layer for being incubated is filled with between described incubator and barrel shape graphite-pipe, described incubator top is also provided with the thermocouple for monitoring temperature in barrel shape graphite-pipe.
Say further, described two accumbency L-type graphite blocks are bolted on the both sides tube wall of graphite-pipe by graphite.
Say further, described incubator is metal material incubator.
Furthermore, described incubator intracavity bottom is positioned at above barrel shape graphite-pipe and is also provided with shell refractory material support.
The utility model has the advantage of: it is positioned at vaccum sensitive stove cast station and can heats precision casting shell online, protect mild temperature control, hot investment casting efficient quick is carried out at vaccum sensitive stove, shorten the process cycle of common hot investment casting, reduce production cost, carry out vacuum precision casting under vacuo simultaneously, effectively prevent the problems such as molten metal air-breathing, oxygenation, burning loss of alloy, the product quality of foundry goods is largely increased.Its structure is simple, and low cost of manufacture is easy to use, is easy to promote.
