SI21313A - Vertical casting of complex alloys into assembly of ingot moulds - Google Patents

Abstract

Vertical casting of complex alloys into an assembly of ingot moulds is a solution for quality casting of complex alloys into ingot moulds, associated with high productivity at the same time. The invention is applicable to casting and metallurgy and that on the field of casting complex alloys into ingot moulds. Traditional casting into individual ingot moulds is replaced by simultaneous casting into several ingot moulds stacked together to make an assembly of moulds. Casting is carried out into a form on the top of ingot moulds, which interconnects several ingot moulds simultaneously. In this way, time intervals between individual castings are eliminated.

Description

VERTICAL CASTING OF COMPLEX ALLOYS IN KOKIL ASSEMBLY

It is an object of the invention to simultaneously cast into several molds with a vertical dividing plane. Preferably, the invention is intended for use in the casting of complex alloys such as vaccines and nodulators, but can also be used for casting other alloys and castings. The area of the invention is foundries and factories of auxiliary foundry and other metallurgical materials, where the quality of the casting surface and dimensional accuracy are not within narrow tolerances.

A technical problem that the invention solves is a mold that allows for simultaneous and continuous casting into several closed molds. The molds are stacked side by side to form a set of molds. The advantage of the invention is that it provides high casting capacity with good cast alloy quality.

The simplest casting of complex alloys so far takes place in an open horizontal mold, but the drawback of the above procedure is the difficulty of hopefully manipulating the casting. Another disadvantage of this process is the large open surface of the casting which oxidizes the ph casting and thus degrades the quality of the part of the casting which is open.

The basic requirement to achieve a satisfactory quality of said complex alloys is to cast into a closed mold and to prevent material from expanding upon curing. In order to achieve these conditions, it is necessary to cast into a closed mold with all necessary manipulation of the mold and further with the casting. It is also necessary to achieve as little as possible in the process of pouring the prepared cast iron from the furnace into the intermediate vessels - pans.

There are several known solutions for casting in closed molds. Classic casting into a single mold is suitable for the production of classic foundry products - castings, and the casting process for these alloys is slow. Another well-known method is casting on a carousel. In most

The -2 example procedure requires spillage into an intermediate casting pan, which, under normal conditions, requires partial combustion and thus direct loss of some elements. However, the capacity of that procedure is satisfactory.

In the same way as casting in our invention, the casting machines of the Disamatic type are used, but in our invention metal molds are also called molds.

Invention of molding into the mold assembly shown in the accompanying figure annexes solves most of the problems and disadvantages noted. Figure 1 shows the molds that are stacked in the mold assembly. Position 1 in Figure 1 indicates the mold, position 2 a casting cavity at the top of which is a casting slot and position 3 a casting channel. The shape of the casting cavity depends on the desired shape of the product to be cast. Figure 2 shows the individual molds of simple shape. Figure 3 shows the casting into the casting channel and the flow through the casting slot into the casting cavity.

As Figure 1 shows, molds shaped like Figure 2 are stacked side by side and placed vertically. The said set of molds may be inserted into a manipulator or other tool to obtain the force required for compression. The said tool is not an object of the invention. The number of molds and the size of the molds depends on the desire and need of the wearer. The casting slot through which the casting cavity is filled is located at the top of the assembly, on the interface between the two molds. The individual casting slots are interconnected by an open casting channel located at the top of the molds.

Casting begins by casting into the casting channel at the beginning of the mold assembly. The casting flows through an individual casting slot into the casting cavity. When the first cavities at the beginning of the assembly are filled, the casting can move beyond the next slots. However, if the number of molds is smaller, the whole assembly can be cast from one place. The entire process is carried out without interruption of casting, therefore, the process is fast and continuous, which is also an advantage of the present invention over existing processes. The casting process takes until the complete set of molds has been cast or until all the casting cavities have been filled.
