Problems solved by technology

Sometimes, in order to speed up the cooling during the casting interval, water is passed directly to the inner wall, which increases the degree of chilling and shortens the life of the mold.
In addition, the currently commonly used outer wall spray cooling method does not control the parameters such as spray form, spray timing, cooling water flow and pressure, and often increases the thermal stress of the cylindrical wall during chilling, not only The cylinder is damaged, and it cannot play its due role in forming molten steel

Abstract

An automatic spray cooling device for a centrifugal casting mold cylinder comprises a mold cylinder (10) and end caps (20) arranged at two ends of the mold cylinder (10). A water header (30) is arranged on the mold cylinder (10), infrared temperature measurers (50) for measuring temperature of the mold cylinder (10) are arranged on a steam deflector (80), spray heads (60) are arranged on the lower side of the water header (30), and a program analysis controller (70) used for controlling water flow electromagnetic valves (40) is arranged on the steam deflector (80). With the automatic spray cooling device, real-time control of temperature of different stages of the mold cylinder is achieved; according to the 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 mold cylinder can be avoided.

Description

technical field [0001] The invention relates to an automatic spray cooling device for a centrifugal casting mold cylinder, which belongs to the field of metallurgical centrifugal casting. Background technique [0002] At present, in the production of centrifugal casting pipes, the molding cylinder is the main process equipment. When a casting pipe is produced during work, the molding cylinder is impacted by molten steel at a temperature above 1350° once, and its cooling rate will directly affect the solidification of molten steel. Different cooling speeds between the cold end and the cold end will lead to differences in the metallographic structure, which will affect the quality of the cast pipe. The rotating cylinder is generally cooled naturally in the air, and the cooling rate cannot be controlled. 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 seriously short...
