Abstract

To transfer the molten metal that is melted in the melting furnace into the pouring ladle, which is a vessel for transporting the molten metal to the place for pouring, and to further lift the pouring ladle by another crane to pour the molten metal, requires time, such that the molten metal that had a high temperature when melted by the melting furnace is likely to cool down and to cause a defective cast product. To solve the problem the pouring equipment of the present invention pours the molten metal into the mold, comprising the melting furnace that produces molten metal by melting metal material and a driving apparatus that can move the melting furnace backward and forward or in a traverse direction, wherein the pouring equipment moves the melting furnace to the predetermined position by the driving apparatus, and then pours the molten metal into a mold by tilting the melting furnace relative to the mold.

First claim

The invention claimed is:

1. Pouring equipment that pours molten metal into a mold, comprising a melting furnace that produces molten metal by melting metal material and a driving apparatus that moves the melting furnace backward and forward and in a traverse direction, wherein the pouring equipment pours the molten metal directly into the mold from the melting furnace by tilting the melting furnace relative to the mold,
wherein the melting furnace has an outflow portion located at an upper portion of the furnace, from which the molten metal is poured into the mold, where a cross-sectional side view of an end-part of the outflow portion has a circular arc, and where a center of a circle that comprises the circular arc is a center for tilting the melting furnace,
wherein the cross-sectional side view of an inner wall of the melting furnace forms a tangent of the circle, and
wherein the melting furnace tilts around two axes for tilting that are disposed between an upper end and a lower end of the melting furnace where a first axis extends perpendicularly to a direction of the tilting of the melting furnace and a second axis, which goes through the center of the circular arc that is formed by the cross-sectional side view of an end-part of the outflow portion and which extends parallel to the first axis, and
wherein the pouring equipment pours the molten metal directly into the mold from the melting furnace where the melting furnace is tilted by being rotated around the first axis, thereby having the outflow portion come closer to the mold just before the start of the pouring and where the melting furnace is further tilted by being rotated around the second axis so as to pour the molten metal into the mold.

2. The pouring equipment of claim 1 , comprising a servomotor for driving the driving apparatus, a driving apparatus for tilting that tilts the melting furnace, a load cell that measures the quantity of the molten metal that was poured from the melting furnace into the mold, and a control apparatus that controls, based on the quantity of the molten metal that was poured, a servomotor for tilting the melting furnace, wherein the pouring equipment automatically pours the molten metal into the mold under the control of the control apparatus.

3. Pouring equipment that pours molten metal into a mold, comprising a melting furnace that produces molten metal by melting metal material and a control apparatus for controlling the position of the mold, which apparatus moves the mold backward and forward and to the left and right relative to the melting furnace, wherein the pouring equipment that pours the molten metal directly into the mold from the melting furnace tilts the melting furnace relative to the mold,
wherein the melting furnace has an outflow portion located at an upper portion of the furnace, from which the molten metal is poured into the mold, where a cross-sectional side view of an end-pad of the outflow portion has a circular arc, and where a center of a circle that comprises the circular arc is a center for tilting the melting furnace,
wherein the cross-sectional side view of an inner wall of the melting furnace forms a tangent of the circle, and
wherein the melting furnace tilts around two axes for tilting that are disposed between an upper end and a lower end of the melting furnace where a first axis extends perpendicularly to a direction of the tilting of the melting furnace and a second axis, which goes through the center of the circular arc that is formed by the cross-sectional side view of an end-part of the outflow portion and which extends parallel to the first axis, and
wherein the pouring equipment pours the molten metal directly into the mold from the melting furnace where the melting furnace is tilted by being rotated around the first axis, thereby having the outflow portion come closer to the mold just before the start of the pouring and where the melting furnace is further tilted by being rotated around the second axis so to as to pour the molten metal into the mold.

4. The pouring equipment of claim 3 , wherein the control apparatus for controlling the position of the mold moves the mold backward and forward, to the left and right, and up and down, relative to the melting furnace.

5. The pouring equipment of claim 3 , comprising a load cell that is used to measure the weight of the mold to calculate the quantity of the molten metal that was poured from the melting furnace into the mold and a device for control that controls the tilting of the melting furnace based on the weight of the molten metal that was poured from the melting furnace into the mold.
