" formation of Handling device "
" effect "
Below, the continuous casting apparatus 1 of embodiments of the present invention is described and uses the magnesium of this device manufacturing or the effect of used for magnesium alloy cast rod and manufacture method thereof.
Mouth under the situation with continuous casting apparatus 1 continuous casting cast rod W, at first, will be supplied at the liquation M of dissolving stove (diagram omission) fusion to keep in the stove 3 as shown in Figure 1.Then, connect the power supply 23 drive compression machines 21 of pressue device 2, the inert gas G that has compressed is sent into the superjacent air space that keeps the liquation M in the stove 3, to keeping liquation M in the stove 3 pressurize (by the operation of pressurizeing) at the pressing mechanism that keeps stove 3 to be provided with.At this moment, for example the proportion of the inert gas G that is made of argon gas is heavier than air, even therefore the upper space in keeping stove 3 is remaining air is arranged, and air also can flow to the upper strata of upper space, and inert gas G concentrates on lower floor.
Thus, the surface of liquation M is covered by inert gas G, and blocking contacts with air, therefore suppresses the generation of oxide.In addition, keep the inert gas G pressurization of pressurized devices 2 supplies of liquation M in the stove 3, surperficial integral body is pressed, thus liquation M in keeping stove 3 towards the maintenance furnace side of feeding pipe 6 peristome 6a flow smoothly and inflow feeding pipe 6 in.
And then, protected cover 32,72 obturations of peristome 31a, 71a that the middle part, way in liquation path 11 forms, liquation path 11 integral body are in air-tight state.Therefore, in liquation path 11, all keep the state that pressurizes by 2 couples of liquation M of pressue device on the whole, correspondingly the accelerated part of this pressurization of the flowing of liquation M in liquation path 11.Even there is the filter F that becomes flow resistance in the result in liquation path 11, can not hinder flowing of liquation M yet.
Liquation M in the described feeding pipe 6 are if come out then to drop in the pans 7 and temporarily stored from the pans side opening 6b of portion.The liquation M that sends in the pans 7 is flowing in pans 7 under the pressurization of described pressue device 2 to mold 9 sides, obtain filtering by filter F, thus, remove the unwanted field trash among the liquation M and purify (operation of the liquation M that has pressurizeed being filtered and transporting through filter F).
Even the filter F perforate degree A that liquation M passes through (the logical liquid path of mesh) is trickle, by the pressurization of described pressue device 2, the logical liquid measure of time per unit also increases, and liquation M flows smoothly.Therefore, filter F improves the ability of removing of field trash, can effectively filter.
The liquation M that is purified by filter F slowly flows in the casting plane of molds 9 through mold mounting disc 8 from the liquation supply port of pans 7.Liquation M contacts with the casting plane that is cooled off by cooling device (diagram is omitted) in mold 9 and is once cooled off, and is frozen into pole shape (cast rod W) when the lubricant of being supplied with by feeding lubricating device (diagram is omitted) is lubricated.
By by roller 10a, the 10b of Handling device 10 to casting direction drawing cast rod W, pull out cast rod W from the mold face of mold 9.The cast rod W that pulls out from the mold face is transported by Handling device 10, and the cooling water that the device that further is cooled simultaneously (diagram is omitted) is emitted is forced the secondary cooling.This cast rod W is also carried to determined location by Handling device 10 drawings, and severing becomes the length of hope.
As mentioned above, liquation M is in continuous casting apparatus 1, and the pressing force of pressurized device 2 pressurizes in the liquation path 11 that is formed air-tight state by protective cover 32,72, and the pressurized part that correspondingly accelerates thus flows.Therefore, even there is flow resistance in liquation M during by filter F, liquation M also flows through smoothly, removes field trash and delivers to mold 9 and cast.
So the cast rod W that is formed by continuous casting apparatus 1 can be with the ingot casting of the good quality of high-speed and continuous Foundry Production.Therefore, continuous casting apparatus 1 can improve the speed and the productivity ratio of producing cast rod W, can produce high-quality cast rod W in a large number in the short time, and can realize the reduction of cost.
