example 1

[0045] Figure 4 It shows the working sequence diagram of the furnace group with liquid-solid metal 90:10 charging. As shown in the figure, the No. 1 aluminum mixed furnace completes the dumping cycle of about 2 hours and enters the process of "cleaning furnace, charging, working, The preparation cycle consisting of "aluminum mixing furnace ready for pouring" takes about 7.16 hours. After the dumping cycle of the No. 1 aluminum mixing furnace, the No. 2 aluminum mixing furnace, the No. 3 aluminum mixing furnace and the No. 4 aluminum mixing furnace are successively put into the dumping cycle, and enter their respective preparation cycles after their respective dumping cycles are over. The dumping cycles of No. 1, No. 2, No. 3 and No. 4 aluminum mixing furnaces are successive, realizing continuous supply of molten aluminum. 38 minutes before the end of the dumping cycle of the No. 4 aluminum mixing furnace, the preparation cycle of the No. 1 aluminum mixing furnace has been co...

example 2

[0047] Figure 5 It shows the working sequence diagram of the furnace group with liquid-solid metal 85:15 charging. As shown in the figure, the duration of the pouring cycle of the aluminum mixing furnace remains unchanged, while the preparation cycle decreases due to the decrease in the proportion of liquid in the liquid-solid metal charge. Extended. Similarly, the dumping cycles of No. 1, No. 2, No. 3 and No. 4 aluminum mixing furnaces are successive, realizing continuous supply of molten aluminum. 19 minutes before the end of the dumping cycle of the No. 4 aluminum mixing furnace, the preparation cycle of the No. 1 aluminum mixing furnace has ended, and it is in a state where it can be put into the dumping cycle again. That is, in this case, the overall cycle is expected to have a buffer time of 19 minutes between the end of the previous preparation cycle and the start of the next pouring cycle for each aluminum mixing furnace, as Figure 5 shown.

Abstract

The invention relates to an aluminium holding furnace group for a matched aluminium continuous casting and rolling production line. The aluminium holding furnace group comprises a plurality of aluminium holding furnaces, wherein each aluminium holding furnace communicates with a runner with a heat-insulation cover; each aluminium holding furnace is equipped with an electrolytic aluminium liquid injection device, an aluminium liquid stirring device, an in-furnace refining device, a combustor and a combustion control system, a furnace body tilting device, an aluminium discharge control system, and an online degassing and filtering device; each aluminium holding furnace is provided with a furnace body tilting hydraulic cylinder, and the furnace body tilting hydraulic cylinder is designed to be suitable for rotating to tilt the aluminium holding furnace under the control of the aluminium discharge control system, thus conveying molten aluminium liquid in the aluminium holding furnace to a continuous casting machine through the corresponding runner.

Description

technical field [0001] The invention relates to the technical field of non-ferrous metal smelting furnaces, in particular to an aluminum mixing furnace group used for supporting aluminum continuous casting and rolling production lines, in particular to an aluminum furnace group used for matching aluminum furnaces based on the Hazlet continuous casting process. Aluminum mixing furnace group of continuous casting and rolling production line. Background technique [0002] Modern aluminum sheet, strip and foil production has three billet production processes: ingot hot rolling, casting rolling, and continuous casting and rolling. Among them, the aluminum continuous casting and rolling production based on the Hazelett continuous casting process has developed rapidly in the past ten years. The aluminum continuous casting and rolling production has incomparable advantages compared with other billet supplying processes: ①Compared with ingot hot rolling, it saves investment such as ...
