Description
Technical field
The invention belongs to metallurgy and foundry technical field, more particularly to a kind of more ingot pouring devices of one furnace of vaccum sensitive stove and
Method.
Background technique
Vaccum sensitive stove passes through production as a kind of common vacuum equipped of smelting special material during electromagnetic induction
Raw eddy current makes the intracorporal raw metal fusing of furnace, and then achievees the purpose that smelting high-purity metal and alloy；As melting is set
The raising of standby ability, currently used vaccum sensitive stove are mostly tonne furnace, corresponding casting die be also it is multiple, due to vacuum
The independence of induction furnace casting system often occur the problem that first in casting process, and in casting process, mold is not
Energy fast accurate is placed in below stopper noz(zle)；Second, during converting mold, furnace in-vivo metal can generate temperature drop, to cause
Energy waste；Third, the molten metal in mold are easy to produce " bridging " phenomenon in process of setting, and with the progress of casting,
Furnace body inner metal liquid temperature is lower, will be unable to carry out solidification feeding to " under bridge ", thus in mold casting be easy to produce it is loose and
Shrinkage cavity and other issues, it is lower so as to cause lumber recovery.
For this purpose, those skilled in the art devise the more ingot pouring devices of a variety of furnaces and method, the following are for example:
1., the Chinese patent application of Publication No. CN105964956A, disclose a kind of steel ingot vacuum induction furnace smelting and pour
Casting method, by the way that circular guideway is arranged in furnace body, and the setting casting vehicle on guide rail, flexible by one end hydraulic stem make to pour
Casting vehicle moves in guide rail, so that mold is accurately placed in below stopper noz(zle), the setting being connected to by ingot mould bottom, to keep away
Exempt from steel ingot shrinkage cavity and other issues；But casting vehicle and the outer hydraulic stem of furnace in additional increase furnace are needed, lead to structure more
Complexity, and cast number of molds it is excessive when, also have higher requirement to the quality of loads of hydraulic stem.
2., the Chinese patent application of Publication No. CN203900455U, disclose a kind of vaccum sensitive stove rotary casting machine
Structure multiple molds is arranged on rotary-tray, by the movement of rotary-tray so that mold is successively rotated to stopper noz(zle)
Side, carries out multimode casting with this；But phase after pouring, the program not can avoid as molten metal temperature reduces and caused by
Ingot quality problem, and with the progress of casting, rotary-tray stress will become unevenly, to cause the acceleration of swivel bearing
Abrasion, and then increase the consumption of smelting cost.
3., the Chinese patent application of Publication No. CN205128856U, disclose a kind of high temperature master alloy production casting
Molten steel is steadily assigned in shunting disk, and then cast by part flow arrangement by design diversion trench and shunting disk by diversion trench
To in each mold；But the program is the simple accurate control for shunting molten steel, failing to accomplish each ingot casting weight
System, and phase after pouring, not can avoid yet as molten steel temperature is lower and caused by shrinkage cavity and other issues.
Summary of the invention
