Problems solved by technology

The vacuum induction melting furnace has the characteristics of negative pressure, the temperature control of the alloy can only be determined by the instrument and the experience of the workers, and it is difficult to control the temperature by directly pouring the crucible into the water-cooled ingot mold, the flow rate is uneven during the pouring process, and the alloy liquid is formed directly Repeated scouring of a fixed arc can easily lead to damage to the water-cooled ingot mold, uneven thickness of alloy crystals, etc.
Therefore, there are defects such as high operational risk and low product quality in crucible pouring.

Embodiment 1

[0017] Example 1: The tundish is formed and sintered with alumina and quartz crushed stone. The outer diameter of the body is 140mm, the inner diameter is 130mm, and the height is 50mm. There is a hemispherical slow-filling bag at the center with a radius of 25mm. With the center point of the buffer bag as the center, draw a cross line, On the cross line, 45mm from the center point is the center of the circle, and four leak holes with a diameter of 30mm are made. In the process of use, the alloy liquid flows into the hemispherical slow filling bag in the tundish during pouring, and the alloy liquid forms a secondary natural pouring distribution and enters the four leakage holes and naturally enters the water-cooled ingot mold. Because the bottom of the tundish is designed to have a concave arc , the alloy liquid left between the leakage holes flows into the leakage hole along the concave bottom, and finally flows into the water-cooled ingot mold, which can solve the problems of...

Abstract

The invention discloses a tundish for vacuum smelting furnace casting. The tundish comprises a blank body, a buffer bag and leaking holes, wherein the buffer bag is a hemispherical buffer bag and is arranged on the bottom surface of the blank body, the leaking holes are formed in the bottom surface of the blank body and are uniformly distributed around the buffer bag. When the tundish is used, the problems of water cooling ingot mold burnthrough, product coarse crystallization and the like can be effectively solved, the operation safety is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to a tundish for pouring, in particular to a tundish for pouring a vacuum induction melting furnace. Background technique [0002] The casting method usually adopted in vacuum induction melting furnaces for hydrogen storage alloys is that the alloy liquid is directly poured from the crucible to the water-cooled ingot mould. The vacuum induction melting furnace has the characteristics of negative pressure, the temperature control of the alloy can only be determined by the instrument and the experience of the workers, and it is difficult to control the temperature by directly pouring the crucible into the water-cooled ingot mold, the flow rate is uneven during the pouring process, and the alloy liquid is formed directly Repeated scouring of a fixed arc can easily lead to damage to the water-cooled ingot mold and uneven thickness of alloy crystals. Therefore, there are defects such as high operational risk and low product quality in...
