Embodiment Construction

[0023] The present invention will be further described below in conjunction with the examples, but the examples should not be construed as limiting the present invention.

[0024] Produced by VIDP4.5 ton vacuum induction melting furnace Taking the vacuum casting system of master alloy ingot as an example, the vacuum casting system such as figure 1 shown.

[0025] The production diameter is Vacuum casting system of master alloy, including VIDP 4.5 tons vacuum induction melting furnace crucible, launder, diverter, diversion plug, heat preservation cap, round mold and lifting tooling.

[0026] According to the size of the casting radius, the number of stations is determined to be 6 stations, and each station has a ten-hole diverter, such as figure 2 As shown, corresponding to 10 round molds, such as image 3 shown. Each station has only one casting point, which is circular, which is conducive to the average distribution of molten steel and the number is 10 holes, which is...

Abstract

The invention discloses a vacuum casting system for manufacturing of mother alloy. The vacuum casting system comprises a vacuum inductive smelting furnace crucible, a sluice, diverters, diversion chock plugs, thermal insulating caps, round dies and hoisting tools. The vacuum casting system is applicable to a large-tonnage vacuum inductive smelting furnace. A larger furnace casting amount is achieved, manufactured cast ingots are same in specification and composition, and the defects of otherness and the volatility in the product quality which are caused by multi-furnace manufacturing of small-tonnage vacuum furnaces can be overcome and eliminated. In addition, to a certain extent, the production efficiency is improved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to a vacuum casting system for producing master alloys. Background technique [0002] At present, in the production of cast high-temperature master alloys, domestic production is almost always carried out by small-scale vacuum induction melting furnaces, with the tonnage ranging from 200 to 2000kg. Therefore, when producing some orders with large demand, we have to adopt the method of multi-furnace production, using small vacuum induction melting furnaces for multiple and repeated production, which will inevitably lead to a longer cycle, and due to multiple It is difficult to achieve uniformity in the quality of ingots for one order of heat production, including composition, surface quality and shrinkage cavity, etc., and it is easy to produce differences and fluctuations in the quality of cast high-temperature master alloys. This difference and fluctuation in quality will cause ...
