Abstract
The invention discloses a dummy bar and its manufacturing process, which has the characteristics of long service life and wide application range. The dummy rod is composed of the dummy head part with different cross-sections; the rod body with different arcs or lengths, the leaf spring and the tail section fixed on the inner arc surface of the dummy rod with different cross-sections and lengths and various radii of curvature . The leaf springs with various curvature radii fixed on the inner arc surface of the dummy bar are made of spring steel materials 60Si2Mn, 55SiMnVB, 60CrMnMo, and are processed by heat treatment, and realized by quenching and tempering. The invention simplifies the operation mode and greatly improves the strength and service life of the dummy bar. Even after the service period is over, the arc shape can be adjusted directly on the spot at will to restore the original curvature radius, which can maintain long-term production and achieve no Return rate and no maintenance effect.
Description
Technical field: [0001] The present invention relates to the technical field of metallurgy, specifically it is a dummy bar and its manufacturing process, which can be used for different circular arcs and rigidities of different radii of the leaf spring structure of various structures in various forms of continuous casting machines Manufacture of elastic dummy rods. Background technique: [0002] The continuous casting machine is an important equipment for metallurgical continuous casting, and the dummy bar is an important part of the continuous casting machine. The dummy bar that continuous casting machine is used at present basically all is made of dummy head, dummy bar, bar body and tail section. The shaft part is usually forged with two sections of straight steel, which are connected after cold bending into a certain arc shape. The radius becomes larger, which brings great difficulties to the dummy bar on and off the machine. Firstly, the larger arc increases the produc...
