Abstract

The invention provides a rigid slab continuous casting slab ingot casting rod. The rigid slab continuous casting slab ingot casting rod is characterized in that in the rigid ingot casting rod, a spring plate is embedded into a key groove and a screw, so that the rigidity of a dummy bar is guaranteed, and the flexibility of the dummy bar is increased. Meanwhile, the spring plate is embedded in thedummy bar, so that lateral bending caused by heat deformation caused by direct radiation of heat on the spring plate is avoided; a roller of a withdrawal and straightening machine can be prevented from directly acting on the spring plate to extrude and deform, and if the clamping forces on the two sides of the withdrawal and straightening roller are different, the spring plate on the two sides extend out. At the same time, each transition section, each connecting section and the like are connected through pin shafts, and each section is provided with a hoisting hole, so that replacement and hoisting of spare parts are facilitated. In addition, the invention provides a manufacturing method of the rigid slab continuous casting slab ingot casting rod.

Description

technical field [0001] The invention relates to a rigid slab continuous casting billet dummy rod and a manufacturing method thereof. Background technique [0002] Dummy bar is an important part of continuous casting machine equipment. Its main function is to play the role of dummy drawing when pouring. At present, the dummy rods of slab continuous casting machines mostly adopt rigid dummy rods, whose main features are flexible introduction, convenient manufacture and transportation. However, due to long-term exposure to high-temperature radiation, extrusion deformation and other reasons during work, problems such as side bending deformation, failure to import normally, and shortened service life often occur. Based on this, we have designed a new type of dummy bar through careful analysis to solve the above problems. Contents of the invention [0003] The technical solution adopted by the present invention for the above-mentioned technical problems is: a rigid slab conti...
