Abstract:
1. A tilting-type automatic pouring method for pouring molten metal from a ladle with an outflow position into a mold, the method comprising: tilting the ladle forward to pour molten metal into the mold; measuring a weight of poured molten metal; calculating a flow rate of the molten metal flowing out of the ladle based on the measured weight of poured molten metal; estimating a weight of molten metal that will be poured during a backward tilting, the estimating comprising: estimating a total weight of molten metal based on the measured weight of poured molten metal and the estimated weight of molten metal that will be poured during the backward tilting; comparing the estimated total weight of molten metal to a predetermined weight; starting, when the estimated total weight is equal to or larger than the predetermined weight, the backward tilting.
