Endless rolling rod production line process device

Abstract

The invention belongs to the technical field of metallurgy, and relates to an endless rolling rod production line process device which comprises a steelmaking and continuous casting unit, an intermediate rolling unit, a temperature control formation rolling unit and a finished product finishing processing unit arranged sequentially. The steelmaking and continuous casting unit comprises a set of casting platform and a multi-way continuous casting guiding mechanism. The intermediate rolling unit comprises a first continuous casting unit, a temperature control device and a first shearing device arranged sequentially. The temperature control formation rolling unit comprises a second continuous casting unit, a front temperature control device, a back temperature control device and a second shearing device. The finishing processing unit corresponds to the temperature control formation rolling unit arranged on the upper stream in parallel, and comprises a high-speed steel loading device, a cooling bed, a corresponding dividing shear and a checking, bundling and collecting device. According to the process and the device, large-scale high-yield continuous casting, endless rolling and directrolling can be realized, and the product quality stability and the process flow smoothness can be further ensured. Meanwhile, the whole device is simple and reliable, and the land occupation and other investment are saved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and relates to a process equipment for an endless rolling bar production line. Background technique [0002] Steel production consumes a lot of resources and energy, and has a huge impact on the environment. Moreover, the scale of iron and steel production is relatively large, which also puts forward higher requirements on the production energy consumption of the process route. How to further reduce production energy consumption is the goal that the steel industry will continue to pursue in the future. The continuous casting slab produced from the steelmaking and continuous casting process directly enters the steel rolling process without heating, which is the most economical and energy-saving production method. In this regard, a large number of researches and improvements have been carried out at home and abroad. [0003] 1) There is a production line that uses a single-strand billet contin...

AI Technical Summary

Problems solved by technology

The production capacity of a single production line in this way is small, the actual output is only 300,000 t / year, and the theoretical design maximum capacity is less than 700,000 t / year. In the consumer market, the competitiveness of this type of small-volume production line is not high

[0005] (1) When the production capacity of two rolling lines is equivalent to that of the conventional one, two complete sets of equipment (including rolling mill and finishing) are required, and the equipment investment is large

[0006] (2) The two rolling lines occupy a large area, and the investment in equipment and civil engineering is large

This process is suitable for small-volume production lines, but for large-scale high-volume production lines, there are disadvantages in terms of stable product quality and smooth process flow.
