T-shaped vacuum induction smelting and casting furnace

Abstract

The invention discloses a T-shaped vacuum induction smelting and casting furnace. The furnace comprises a vacuum smelting chamber, a smelting furnace arranged inside the vacuum smelting chamber and vacuum valves connected with the vacuum smelting chamber through pipelines, wherein the top of the vacuum smelting chamber is provided with a movable furnace cover, the vacuum smelting chamber is provided with two outlets, and the two outlets are respectively provided with a mold inlet chamber and a mold outlet chamber. The T-shaped vacuum induction smelting and casting furnace further comprises a flow groove chamber and a side feeding chamber, wherein the flow groove chamber is arranged outside the vacuum smelting chamber and communicates with the vacuum smelting chamber for guiding molten steel in the smelting furnace into an ingot mold; and the side feeding chamber is arranged outside the vacuum smelting furnace and communicates with the vacuum smelting chamber for feeding the smelting furnace. By arranging the mold inlet chamber and the mold outlet chamber, the time influence of casting circulation and frequent switching of the vacuum degree are greatly reduced, a large amount of energy consumption is saved, streamlined casting production can be realized, and the casting efficiency of castings is improved.

Description

technical field [0001] The invention relates to the technical field of metal vacuum melting and casting, in particular to a T-shaped vacuum induction melting and casting furnace. Background technique [0002] Vacuum induction melting is a method of smelting by using electromagnetic induction to generate eddy current in the metal conductor to heat the furnace material under vacuum conditions. The metal is melted and then used for casting; while the existing vacuum induction melting casting furnace generally has one-way ingot ingot. , that is, the ingot enters the vacuum chamber to evacuate and then enters the melting and casting furnace, then pours molten steel into the ingot, and then sends the ingot out through the original outlet, so that there will be many uncontrollable factors in the middle that lead to The casted products do not meet the requirements, and the casting efficiency is still low. [0003] The one-way entry and exit of the ingot into and out of the vacuum m...
