Cooling holder applied to thermal type continuous casting equipment

Abstract

The invention discloses a cooling holder applied to thermal type continuous casting equipment. The cooling holder comprises a housing; the housing is provided with a passage for a cast piece to pass through; a water spraying device and a damping device are arranged inside the housing, wherein the water spraying device is used for spraying water to the cast piece which passes through the passage; the damping device clings to the cast piece in order to prevent shock of the cast piece; and the water spraying device and the damping device are sequentially arranged inside the housing in the pass-through direction of the cast piece in the passage so that the damping device can cling to the cast piece which is cooled by the water spraying device. The water spraying device and the damping device are sequentially arranged inside the housing in the direction where the cast piece passes through the passage, so the cast piece can be firstly cooled by the water spraying device after entering the passage and then clings to the damping device; when the cast piece is subjected to shock transmitted by a pulling device, the damping device can achieve a damping effect in order to prevent the shock from being transmitted to the outlet of a casting mold so that the surface smoothness of the cast piece is not affected, therefore the stability of the cast piece in a production process is greatly improved, and the surface smoothness of the cast piece is improved.

Description

technical field [0001] The invention relates to the technical field of hot-type continuous casting, and more specifically relates to a cooling holder for hot-type continuous casting equipment. Background technique [0002] Hot-type continuous casting is a directional solidification continuous casting technology. The molten metal solidifies into castings at the outlet of the mold, so the castings at the outlet of the mold are relatively soft, not at room temperature, and prone to deformation. The traction wheel is connected to the motor, which is used to continuously pull the casting out from the mold outlet. The traction wheel also provides vibration to the casting while providing traction. Since the traction wheel is far away from the mold mouth, a small amount of vibration is transmitted to the mold The mouth will cause a large swing, making the newly solidified casting prone to bamboo-shaped cracks and unable to obtain a smooth surface. [0003] Therefore, how to solve t...
