Embodiment Construction

[0016] ①As shown in Figure 1 and Figure 2, the molten steel 2 in the ladle 1 is injected into the tundish 3, and then the nozzle 4 connected with the tundish 3 flows into the tundish formed by a pair of casting rolls 6 and two side sealing plates 5. In the wedge-shaped molten pool, a pair of casting rolls 6 that continuously rotate in reverse (see the direction of the arrow of casting roll 6 in Figure 1) through which cooling water passes through, exchange the molten metal in the wedge-shaped molten pool through heat exchange, so that the molten metal is gradually cooled and solidified , deformation, casting and rolling out two-way strips with a section consistent with the pass type (limited to circular section, square section, rectangular section, and hexagonal section), enter the cooler 7 to continue cooling, and are guided by the arc guide plate 8 to enter the pinch roller 9. The two-way strips that come out are separated by the separation block 11, and enter the rolling mil...

Abstract

The present invention relates to a new process for continuously casting and rolling bar material, belonging to the field of metallurgical forming technology. It is characterized by that it is a technical process for directly casting liquid metal and rolling it to make it be formed into bar material. Said invention also provides the concrete steps of said new process.

Description

Technical field: [0001] The invention belongs to the technical field of metallurgical forming, and in particular relates to a process method for directly pouring liquid metal and continuously casting and rolling forming. Background technique: [0002] At present, the production process of metal strips of various cross-sections at home and abroad is mostly produced by multiple processes such as continuous casting → billeting → rough rolling → intermediate rolling → continuous rolling → crimping or cutting to length. The disadvantage of this method is that there are many production passes, the production equipment occupies a large area, the workshop span is long, and the production cost is high. Invention content: [0003] The purpose of the present invention is to provide a new continuous casting and rolling process, which can effectively overcome the shortcomings of the existing process. [0004] The present invention is realized in that it is composed of ladle 1, tundish...
