Lifting appliance for casting rods

Abstract

The invention discloses a lifting appliance for casting rods. The lifting appliance comprises a support, slinger rings and connecting pieces, wherein two ends of the connecting pieces are respectively connected with the slinger rings and the support; a limit hole used for hanging the casting rod is formed in each slinger ring; the top end and bottom end of each limit hole are provided with clamping teeth used for clamping the casting rod; each limit hole is an elliptical hole; and the clamping teeth are arranged at two ends of a long axis of each limit hole. When the casting rods need to be lifted, the slinger rings sleeve the casting rods, and after the casting rods are conveyed to the designated position, the casting rods are dismounted from the lifting appliance; when the casting rods are lifted by the lifting appliance, the casting rods incline under the effect of self-gravity; since the limit holes in the slinger rings are the elliptical holes, the contact areas between the casting rods and the side walls of the limit holes are increased, so the condition of overlarge local stresses of the casting rods is avoided. The lifting appliance for casting rods has the advantages that the lifting quality is good and the pressing depth of surfaces of the casting rods is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of cast rod lifting, in particular to a spreader for cast rods. Background technique [0002] In semi-continuous casting, the metal melt is evenly introduced into the crystallizer whose outer wall is cooled by water, and solidifies and crystallizes under the action of the mold wall and the crystallizer base, and then forms a relatively solid solidified shell. When the horizontal liquid level of the body reaches the preset height, the traction mechanism of the casting machine drives the base and the solidified shell that has solidified on the base to move downward continuously and evenly at a certain speed. Among them, the part that has been solidified into an ingot out of the crystallizer is immediately cooled by the cooling water directly, and the crystal layer of the ingot is continuously advanced to the central area and is completely solidified and crystallized. After the ingot length reaches the specifie...

Problems solved by technology

[0004] However, since the limit hole is a round hole, when the spreader lifts and transports the cast rod, under the action of gravity, the cast rod is inclined relative to the lifting ring 01, so that the contact area between the casting rod and the lifting ring 01 is small, and the local stress of the casting rod Increased, resulting in deep bite marks in the part of the cast rod, resulting in poor lifting quality of the lifting ring 01
