How to Arrange Rolling Mills for the Steel Rolling Production Line?

The layout of the rolling mills in the steel rolling production line determines the size of the entire production line. Therefore, how to arrange the machine is particularly important. Under normal circumstances, the rolling machine in the rolling production line can be divided into the following types.

Stand-Alone

The formation of a stand-up rolling machine is the simplest. The steel rolling workshop is composed of only one working machine seat and its drive motor and transmission system. This layout is used for:

(1) The first rolling machine, board rolling machine, thick board and universal rolling machine with rolling giant sections are all two-roller reversible rolling machines;

(2) Rolling steel pipes, cold-rolled steel plates and two rollers with steel irreversible rolling machines;

(3) Cold-rolled sheets and four-rolling machines with steel and hot-rolled steel plates and multi-roller rolling machines.

Horizontal

Several working machine seats are rowed into a column, which is transmitted by a motor through co -reduction and gear seats. The advantage of this layout is that the equipment is simple, the cost is low, and it is easy to build. It has played a great role in the development of the local steel industry. In the past, small and medium -sized steel workshops were mostly used in this type of layout, which has gradually been eliminated. Its main disadvantage is that it is driven by an electric motor. The roll speed of each working machine seat is the same, so the rolling speed cannot be increased with the increase of the rolled parts. At the same time, when rolling parts are sent from one machine to another, they must move horizontally, which is not convenient, but also restricts the improvement of productivity. In a column, the number of working machine seats can reach 2 to 5 according to the different uses of the rolling machine. The horizontal layout is used for rolled steel, wires, etc.

Vertical

The two working machine seats are rolled in order in order of rolling parts, and rolling parts are rolled in each seat. Each machine is driven separately, and the roll speed increases with the length of the rolling part. This layout is commonly used for high productivity initial rolling machines and thick board rolling machines.

Phase

This layout is a combination of the aforementioned arrangement. The rolling line is arranged into three columns (vertical type) in turn. In the second column, there are 3 working machine seats (horizontal type). This layout is commonly used for rolled steel, and the number of mills and seats determines the conditions of the hole design.

Continuous

The continuously arranged rolling machine is mostly a two-roller or a four-roller rolling machine. In addition to each rolling one by one, the roll is relatively short, and it must also be maintained into a rolling machine with equal metal flow within the time of the rolling machine. in principle. Because the continuously arranged rolling machine is easy to achieve the mechanization and automation of the rolling process, it can use a high rolling speed. Therefore, it has a great production capacity. The quality of rolling products is better. At present, steel production, steel plates and steel production, small and wire production, and steel pipe production have been widely used in a large number of rolling machines.

The above is the layout of several rolling machines in the rolling production line. I hope this article will help everyone.
