Problems solved by technology

In this way, the sensible heat of the hot billet cannot be fully utilized, and the full energy saving effect cannot be achieved.
At the same time, the equipment between continuous casting and rolling is also complicated and the investment is high
[0013] Continuous casting and rolling is currently recognized as an economical and effective production process in the field of steel rolling. It has been widely used in the field of strip materials, but it has not yet set foot in the field of long products.
The main reason is that the strip runs in a single stream in the continuous casting machine, while the long material runs in multiple streams in the continuous casting machine, that is to say, the multi-stream running mode of the long material cannot be applied to the existing continuous casting rolling process

Embodiment approach 1

[0043] Such as figure 1 As shown, the embodiment of the present invention proposes a continuous casting and rolling device for producing long products, which includes a continuous casting machine 1, and the rear part of the cutting machine of the continuous casting machine 1 is closely connected with a roller hearth heating furnace 2 in sequence. , a traverse device 3 and a rolling mill 4 capable of low-temperature rolling.

[0044] The application process of this embodiment is as follows: the long material generally enters the continuous casting machine 1 in a multi-flow manner to produce multi-flow slabs. After the billet is cut by the cutting machine of the continuous casting machine, it directly enters the roller hearth heating furnace 2. Through the roller hearth heating furnace 2, the sensible heat of the billet can be realized and utilized, and the billet can be effectively heated and kept warm to make it cast The billet temperature reaches about 950-1050° C., so as to...

Embodiment approach 2

[0054] Embodiments of the present invention also propose a continuous casting and rolling method for producing long products, which includes the following steps:

[0055] A. Long products enter the continuous casting machine in a multi-strand manner to produce multi-strand slabs;

[0056] B. After the billet is cut by the cutting machine of the continuous casting machine, it directly enters the roller hearth heating furnace for heating and heat preservation;

[0057] C. The cast slabs coming out of the roller hearth heating furnace are sent to the rolling mill in sequence for each flow of slabs through the traverse device and directly rolled at low temperature.

[0058] Other structures, working principles and beneficial effects of this specific embodiment are the same as those of specific embodiment 1, and will not be repeated here.

Abstract

The invention discloses a continuous casting and rolling device and method for producing long profiles. The continuous casting and rolling device comprises a continuous casting machine. The rear part of a cutting machine of the continuous casting machine is closely connected with a roller-hearth type heating furnace, a translating device and a rolling machine in sequence, wherein the rolling machine is used for rolling at low temperature. Because the rear part of a cutting machine of the continuous casting machine is closely connected with the roller-hearth type heating furnace, the translating device and the rolling machine 4, and the rolling machine 4 is used for rolling at low temperature, the continuous casting and rolling process of the long profiles can be realized in the embodiment of the invention, the energy consumed for producing the long profiles conventionally can be reduced greatly, the investment of equipment of producing the long profiles conventionally and the floor area can be saved, and the amount of labor and the consumption of metal can be decreased.

Description

technical field [0001] The invention relates to the technical field of steel design and production, in particular to a continuous casting and rolling device and method, in particular to a continuous casting and rolling device and method for producing long products. Background technique [0002] The conventional method for producing long products mainly includes the following steps: [0003] A. The billet produced by the continuous casting machine is flame-cut to form a multi-strand billet; [0004] B. The multi-strand billet is sent to the cooling bed and off-line through the traverse car or billet roller table; [0005] C. The billets are sent horizontally one by one to the walking heating furnace for heating; [0006] D. The slab heated by the walking heating furnace is sent to the rolling mill for high-temperature rolling. [0007] Alternatively, the conventional method for producing long products mainly includes the following steps: [0008] A. The billet produced by...
