Embodiment 1

[0031] The continuous casting round billet quick-change coupling in this embodiment includes a tie-bar frame and a hook-shaped tie-bar 5. The tie-bar frame can be a frame structure, and the tie-bar 5 is hooked and fixedly connected to the tie-bar frame; The bar frame and the tie bar 5 are generally made of steel material. The tie bar 5 can be made of steel bars, of course, round steel can also be used. The tie bar frame is generally made of round steel, which has high support strength.

[0032] In the application of the continuous casting round billet quick-change coupling of this embodiment, the continuous casting round billet quick-change coupling body 10 is inserted into the liquid level line 100 of the molten steel in the mold 30 in the gap between the replacement of the tundish 20, which is sufficient Using the initial pre-solidified state of the molten steel in the mold, it has a certain viscosity, which is equivalent to being suspended in the liquid level of the round bi...

Embodiment 2

[0034] The basic structure of the continuous casting round billet quick-change coupling of this embodiment is the same as that of Embodiment 1, and the differences and improvements are as follows: figure 1 , 2 As shown, the tie frame is a circular frame that fits the shape of the round blank of the crystallizer 30, and includes a circular upper hanging ring 1 and a lower hanging ring 2 that are fixedly connected by the vertical link 3, which is convenient for the suspension of the tie bar 5. After fixing, The vertical link 3 is generally a round steel with high strength, and is fixed symmetrically or uniformly on the inner side of the upper hanging ring 1 and the lower hanging ring 2, usually by welding; the tie bars 5 evenly or symmetrically surround the upper hanging ring. 1. Hook type fixation, the hanging density can be as large as possible, the spacing distance is about 5 times the diameter of the tie bar 5, which can achieve the purpose of uniform casting with molten ste...

Embodiment 3

[0036] The basic structure of the continuous casting round billet quick-change coupling of this embodiment is the same as that of Embodiment 2, and the differences and improvements are as follows: figure 2 As shown, the inner side of the upper hanging ring 1 is fixedly connected with a square upper hanging frame 4; the upper hanging frame 4 is also hooked and fixedly connected to a hook-shaped tie bar 5 to increase the hanging point of the tie bar 5, and further Improve the overall consistency of the uniform cast slab after the molten steel solidifies. The inner side of the lower hanging ring 2 is connected with a transverse link 6, which can be staggered in an X shape to increase the support strength of the lower hanging ring 2; the tie bar 5 includes an inner hook rod 51 on the inner side of the tie frame frame and an outer hook on the outside Rod 52, the length of the outer hook rod 52 is longer than that of the inner hook rod 51, and is inclined downward and outward, whic...

Abstract

The invention discloses a continuous casting round billet quick-change connecting piece and application thereof, and belongs to the technical field of molten steel smelting equipment. The continuous casting round billet quick-change connecting piece comprises a lacing wire frame and a hook-shaped lacing wire, and the lacing wire is fixedly connected to the lacing wire frame in a hooking mode; the lacing wire frame and the lacing wire are made of steel materials, the round billet connecting piece is rapidly placed on the liquid level of a round billet crystallizer in the replacement gap of the tundish, the lacing wire plays a role in connecting the upper part and the lower part, and the whole round billet connecting piece is melted in molten steel, and the molten steel is solidified in the crystallizer. Molten steel casting blanks in the tundish crystallizer in front of and behind the round blank connecting piece are integrated, so that the head cutting of the round casting blanks is reduced. Therefore, the problem that in the molten steel continuous casting process in the prior art, the cropping ratio of a casting blank is high is solved.

Description

technical field [0001] The invention relates to the technical field of molten steel smelting equipment, in particular to a quick-change coupling for continuous casting round billets and its application. Background technique [0002] The near-net-shape continuous casting billets of non-ferrous and ferrous metals have developed rapidly due to their advantages in production efficiency, yield, product quality, automation, energy saving and emission reduction, and the continuous casting ratio has subsequently become a measure of continuous casting technology in various countries. It is one of the indicators of the level and manufacturing capacity of continuous casting equipment. In the metallurgical environment, there is a trend of heavy continuous casting and light die casting in various countries. The proportion of die casting research and application is small, and the design capability and system innovation are lacking. However, continuous casting cannot meet the special need...
