Abstract

The invention belongs to the technical field of cast casting, and discloses a cooling heat radiation device for improving the cast coagulation efficiency. The cooling heat radiation device comprises awater inlet pipeline, a water outlet pipeline and a PLC (Programmable Logic Controller), wherein a plurality of cooling modules in parallel arrangement are arranged between the water inlet pipeline and the water outlet pipeline; each cooling module comprises a sealed cooling box; a water inlet communicating with the water inlet pipeline is formed in one end of the sealed cooling box; a water outlet communicating with the water outlet pipeline is formed in the other end of the sealed cooling box; a temperature control valve is arranged on the water inlet; a temperature sensor is arranged on the water outlet; a cooling pipe is arranged in the sealed cooling box; one end of the cooling pipe communicates with the water inlet; the other end of the cooling pipe communicates with the water outlet; and the PLC is connected with the temperature control valve and the temperature sensor. The cooling heat radiation device has the advantages that the operability and the controllability are high; the controllable precision is high; and each part of a cast can be cooled and coagulated according to the required temperature gradient. The invention also discloses a method for controlling the cast coagulation by using the cooling heat radiation device. The method has the advantages that the operability and the controllability are high; the controllable precision is high; and the quality of the prepared cast is high.

Description

technical field [0001] The invention belongs to the technical field of casting castings, and in particular relates to a cooling and heat dissipation device for improving the solidification efficiency of castings and a casting solidification method. Background technique [0002] In order to make the whole or part of the casting have higher mechanical properties, the casting needs to have a larger temperature gradient and a faster solidification speed during the solidification process. The faster the solidification speed, the finer the grain of the casting, the finer the secondary phase, porosity, pores and inclusions between the crystal axes, and the easier it is to obtain a uniform structure after heat treatment. In a working cycle, the time required for condensation is often the longest. In the traditional pouring process, chilled iron is often used to increase the temperature gradient in the solidification process and accelerate the solidification speed, but the chilled a...
