Uphill casting type induction suspension cold crucible and pouring method

Abstract

The invention discloses an uphill casting type induction suspension cold crucible and a pouring method. The uphill casting type induction suspension cold crucible comprises a water cooling crucible and an induction heating coil. A cooling water channel is arranged in the water cooling crucible, crucible cooling water enters from the a crucible cooling water inlet, through the cooling water channel, cooling of the crucible is achieved, and water is drained through a crucible cooling water outlet; a falling opening is formed in the bottom of the water cooling crucible, and right faces the centreof a pouring cup of a mold shell, the falling opening is controlled through a discharging control rod to achieve opening and closing, a discharging valve comprises a discharging valve water inlet, adischarging valve water outlet, a water guide cone and a water guide plate, discharging valve cooling water enters the discharging valve through the discharging valve water inlet, and is drained through the discharging valve water outlet, a cooling water channel in the discharging valve is formed by the water guide cone, the water guide plate and a discharging valve shell, and a hinge joint can beformed by an inlet and outlet cooling water pipe of the discharging valve. The whole crucible is arranged on a support. The crucible is more easy and convenient to operate and safe.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to a bottom-cast induction suspension cold crucible and a pouring method thereof. Background technique [0002] Induction shell smelting technology is to put solid metal raw materials into a water-cooled crucible wound by an induction coil. When the current flows through the induction coil, an induced electromotive force is generated and an eddy current is generated inside the metal charge. The current calorific value is greater than the heat dissipation of the metal charge. When the speed is high, as the heat accumulates more and more, when it reaches a certain level, the metal melts from solid to liquid, achieving the purpose of smelting metal. During this process, the entire melting process takes place in a vacuum environment, and the inside of the crucible is maintained by water cooling, forming a layer of metal solidification shell formed by the charge between the crucible and the...

Problems solved by technology

[0003] In the traditional pouring process, due to the cooling of the water-cooled crucible during the smelting process, the inner wall of the crucible has a condensed shell, and the liquid metal exists in the condensed shell. The casting module can only be realized by pouring the crucible to make the liquid metal flow out. This pouring method will Increase the heat exchange between the liquid metal and the crucible wall, reduce the superheat of the metal, increase the thickness of the solidified shell, reduce the utilization rate of the material, and the smelting of the metal often produces various types of impurities on its liquid surface, dumping the liquid metal The pouring method will first pour the surface metal with impurities into the mold group, which will pollute the casting and may cause segregation, and the operation is very inconvenient
