Abstract

A spray cooling device for a centrifugal casting metal mold consists of an automatic temperature monitoring feedback system and spraying equipment and comprises a mold cylinder (10), end caps (20), an air header (30), a water header (40), electromagnetic valves (50), infrared probes (60), spraying nozzles (70), a temperature sensor (80), a steam deflector (90) and an induced draft fan (100). The automatic temperature monitoring feedback system includes the infrared probes (60) and the temperature sensor (80); the spraying equipment includes the air header (30), the water header (40), the electromagnetic valves (50) and the spraying nozzles (70); the spraying nozzles (70) are of two-way annular design with water running in an inner way and air running in an outer way, so that spraying is achieved by adjusting flow ratio of air and water. By the spray cooling device, real-time control of temperature of different stages of the metal mold is achieved; according to temperature feedback, spraying volume of different stages is changed automatically, casting mold temperature field is adjusted, structure segregation during solidification of metal liquid is controlled effectively, and local overheating of the casting mold can be avoided.

Description

technical field [0001] The invention relates to a centrifugal casting metal mold spray cooling device, which belongs to the field of metallurgical centrifugal casting. Background technique [0002] In the production of centrifugal cast pipe, the casting mold is the main process equipment, and its cooling rate directly affects the quality of the cast pipe during the casting process. The rotary mold is generally cooled naturally in the air and has no control ability. Sometimes, in order to speed up the cooling during the casting interval, water is directly passed to the inner wall, which increases the degree of chilling and shortens the life of the mold. At present, in the production of centrifugal cast pipes, the casting mold is the main process equipment, and its cooling rate directly affects the quality of the cast pipes during the casting process. The rotary mold is generally cooled naturally in the air and has no control ability. Sometimes, in order to speed up the coo...
