Problems solved by technology

[0002] When pouring steel ingots, the method of pouring steel ingots under non-vacuum cannot be copied into the vacuum induction furnace, such as: the middle column tube, the sand sealing method of the intestinal tract is not suitable for vacuum state
The pouring of the steel ingot in the vacuum induction furnace is generally carried out by top pouring, which has the following defects: steel nodules formed by splashing of molten steel, pits formed by long-term scouring of the bottom of the steel mold, loose center, and air holes in the cap mouth, etc., which bring quality problems to the subsequent processing And the yield is not high, the consumption of raw materials is too large, the production cost is high, the quality is poor, and the economic benefit is low

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 , figure 2 As shown, a combined cast-down dual mold for a vacuum induction furnace includes a combined mold I1 and a combined mold II2. 2. Two groups of connecting seats 7 on the outside of the combination mold II2. After the combination of the described combination mold I1 and the combination mold II2, the steel ingot mold holes 4 on both sides and the central column hole 5 in the middle are formed. The steel ingot mold holes 4 The bottom communicates with the central column hole 5 through the diversion hole 6; the horizontal section shape of the steel ingot mold hole 4 and the central column hole 5 is circular; the diameter of the steel ingot mold hole 4 is greater than the diameter of the central column hole 5.

[0014] The embodiments of the present invention have been described in detail above, but these are just...

Abstract

The invention discloses a downward-pouring combined double-mold assembly for a vacuum induction furnace. The downward-pouring combined double-mold assembly comprises a combination mold I and a combination mold II, wherein when the combination mold I and the combination mold II are combined, two connection bases correspondingly arranged on outer sides of the combination mold I and the combination mold II are fixedly connected through bolts respectively, after the combination mold I and the combination mold II are combined, ingot mold holes in two sides and a middle column hole in the middle are formed, and the bottoms of the ingot mold holes are communicated with the middle column hole through a flow guide hole. The downward-pouring combined double-mold assembly has the advantages that the structure is simple, operation is convenient, the quality of steel ingots is good, the yield of the steel ingots is high, and the economic efficiency is good.

Description

technical field [0001] The invention relates to the field of steel ingot casting mold equipment for a vacuum induction furnace, in particular to a combined down-casting double mold for a vacuum induction furnace. Background technique [0002] When casting steel ingots, the method of pouring steel ingots under non-vacuum cannot be copied into the vacuum induction furnace, such as: the middle column tube, and the sand sealing method of the intestinal tract is not suitable for vacuum state. The pouring of the steel ingot in the vacuum induction furnace is generally carried out by top pouring, which has the following defects: steel nodules formed by splashing of molten steel, pits formed by long-term scouring of the bottom of the steel mold, loose center, and air holes in the cap mouth, etc., which bring quality problems to the subsequent processing And the yield is not high, the consumption of raw materials is too large, the production cost is high, the quality is poor, and the...
