Abstract

The invention discloses a centrifugal casting testing machine. The centrifugal casting testing machine includes a pouring cup, a cover plate, cooling water pipes, a drive motor, a belt and a belt pulley, an ultrasonic probe, an ultrasonic generator, a base, a bearing, a rotating shaft, a lower layer of a turntable, an upper layer of the turntable, heating resistance wires, a furnace wall and a temperature sensor; the upper layer of the turntable is provided with guide sleeves and keys, and the lower layer of the turntable is provided with corresponding guide columns and keyways; and the lowerlayer of the turntable is connected with the rotating shaft and is disposed in a furnace provided with the heating resistance wires and the cooling water pipes, and the ultrasonic generator and the ultrasonic probe are disposed at the central part of the rotating shaft. The centrifugal casting testing machine further exerts the effect of ultrasonic waves in the centrifugation process, heating is performed during the casting solidification process, so that the solidification rate is lowered and the internal fluidity of a melt is increased; and residual heat can be utilized to perform heat treatment for a casting, and the performance of the casting is further improved.

Description

Technical field [0001] The invention relates to the technical field of centrifugal casting machines, in particular to a centrifugal casting test machine. Background technique [0002] Centrifugal casting is a method in which molten metal is poured into a high-speed rotating cavity and solidified under the action of centrifugal force to obtain castings. It is often used to manufacture composite metal castings of cylindrical sleeves. For composite materials containing a high melting point reinforcing phase, during centrifugal casting, a composite material with a gradient distribution of the reinforcing phase is obtained. However, due to the large cooling rate caused by the metal mold, the melt is cooled faster, and the fluidity of the reinforcing phase under the action of centrifugal force is insufficient. When heat treatment is performed on the casting, the casting must be cooled and then reheated. Therefore, the heating time is longer and a certain amount of energy waste is also...

Problems solved by technology

However, due to the larger cooling rate caused by the metal mold, the melt is cooled faster, and the fluidity of the reinforcing phase under the action of centrifugal force is insufficient

When the casting is heat treated, the casting needs to be cooled and then reheated, so the heating time is longer, and it also causes a certain amount of energy waste.
