Embodiment 1
[0024] Such as figure 1 As shown, the "ring group structure" 1 uses molybdenum material, that is, each ring in the structure is made of molybdenum, and the molybdenum and molybdenum sheets are tightly stacked together to form a cylindrical "ring". Group Structure" 1. The thickness of each molybdenum sheet is 0.1 mm. The inner surface of the "ring group structure" 1 is closely connected to the "connecting layer" 2, and the material of the connecting layer 2 is conventional heat-conducting adhesive, which is used to bond the ring group structure in the cylinder to the water-cooled roller core 3 inside the cylinder. connected together. The material of the water-cooled roller core 3 is made of pure copper. The quenching roll composed of the above structure, after the continuous pouring test of 3000 kg of melt at 1600 ° C, no cracks appear on the surface of the roll.
Embodiment 2
[0026] The ring piece group structure 1 in embodiment 2 has the same structural features as that in embodiment 1, and is formed by many ring pieces in close contact. The rings in the "ring group structure" 1 are made of two materials, copper and molybdenum, and the copper and molybdenum sheets are alternately and tightly stacked together to form a cylindrical "ring group structure" 1. The thickness of each copper sheet is 1 micron, and the thickness of each molybdenum sheet is 0.5 mm. The inner surface of the "ring group structure" 1 is closely connected to the "connecting layer" 2, the material of the connecting layer 2 is silver glue, which is used to bond the ring group structure in the cylinder to the water-cooled roller core 3 inside the cylinder together. The material of the water-cooled roller core 3 is made of molybdenum alloy. The quenching roll composed of the above structure, after the continuous pouring test of 4500 kg of melt at 1600 ° C, no cracks appear on the...
Embodiment 3
[0028] In Example 3, the ring pieces in the "ring piece group structure" 1 are made of brass alloy sheets, and the brass pieces are tightly laminated together to form a cylindrical "ring piece group structure" 1 . The thickness of each brass sheet is 2mm. The inner surface of the "ring group structure" 1 is closely connected with the "connecting layer" 2. The material of the connecting layer 2 is conventional metal brazing material, which is used to connect the ring group structure in the cylinder with the water-cooled roller core in the cylinder. 3 welded together. The material of the water-cooled roller core 3 is made of brass alloy. The quenching roll composed of the above structure, after continuous pouring test of 2500 kg of melt at 1600 ° C, no cracks appear on the surface of the roll.
