Description
Technical Field
The invention belongs to the technical field of ferrous metallurgy continuous casting production, and particularly relates to an arrangement structure of a cast blank cleaning and stockpiling area and an operation method.
Background
From the beginning of the twentieth century and the fifties, the continuous casting production process starts in metal smelteries of European and American countries, and compared with the traditional die casting process, the process for directly casting and forming liquid metal into blanks by a continuous casting machine greatly shortens the production time and improves the working efficiency. However, the produced blank has more surface and subcutaneous defects, so that a blank cleaning area and a blank storage area are specially arranged in a casting shop to clean and store the blank. In the foundry plant, at least one bay is generally provided for the above-mentioned functions. The qualified billets are directly conveyed to a rolling workshop or are conveyed to the rolling workshop after being stacked and cooled in a casting workshop, and the billets conveyed to the rolling workshop are directly rolled or are off-line to a billet stacking area of the rolling workshop according to a rolling plan to be rolled for subsequent rolling. In the mill room, at least one bay is generally also provided for the above-mentioned functions. The above-described process arrangements for providing stock dump areas in the casting shop and the rolling shop, respectively, are long standing typical arrangements. However, the following problems exist:
1) when a factory building is built, the investment of traveling cranes, factory buildings, floor hardening and the like needs to be correspondingly configured every time a blank stockpiling area is added, and the investment cost is increased. Taking a one-span billet storage area of a certain steel mill as an example, the width of the one-span billet storage area is 30m, the length of the one-span billet storage area is 260m, 2 12.5t +12.5t rotary clamp cranes are configured, and the investment of the unit factory building area is 2500 yuan/m2The unit price of the crane is 2500000 Yuan/platform. The investment across the billet storage area is 30 × 260 × 2500+2 × 2500000 ═ 24500000, namely 2450 ten thousand yuan.
2) Along with the improvement of the understanding level of metallurgy workers to the casting process of the smelting process, the quality of the produced casting blank is greatly improved, a lot of blanks produced by a casting workshop do not need to directly enter the rolling workshop for rolling through offline cleaning and stockpiling links, and in production operation, when a blank stockpiling area is added, the distance between the blanks transported from the casting workshop to the rolling workshop is at least prolonged by 30m, so that the temperature drop of the casting blank is increased. In a steel mill with annual output of 1000 ten thousand tons, nearly thousand tons of standard coal are wasted every year when the high-temperature blank is reduced by 5 ℃.
3) The blank storage area is a buffer area for the casting process and the rolling process, and the blank storage areas are respectively arranged in the casting workshop and the rolling workshop, so that the stability in the production process is improved (even if a casting machine fails, the rolling plan is not influenced), and the inventory cost is increased.
4) And the casting shop and the rolling shop are respectively provided with a blank stacking area, when a rolling plan is prepared, only the stacking condition of blanks in the rolling shop is considered, and the prepared rolling plan is a local optimal plan, but a global optimal rolling plan cannot be prepared according to the blank stacking condition in the casting shop.
