Description

2. A pallet according to claim 1, characterized in that it is supplied according to

the perimeter of the protruding sides, one of which made the window.

The invention relates to ferrous metallurgy and can be used in siphon steel casting. A siphon ingot casting pan is known, made in the form of a slab with channels for placing siphon wiring into them, the channels in the lower part are made wider by an amount equal to 10-50% of the siphon wiring width. , and along the walls of the channel from the upper part of the pallet to the wider lower part of the channel, through holes 1J are made. However, the use of a pallet does not exclude the possibility of breakthrough siphon wiring. When the siphon wire is broken, the metal gets into the dried part of the channel, it is welded to the siphon wiring, thus forming a wedge that extends downwards, which prevents the sprue from being removed and the channels released. . The closest in technical essence and the achieved result proposed is a siphon metal casting tray made in the form of a metal plate, having a nest for the center and outflow channels from it for laying fire resistant siphon wiring 2 i The disadvantage of this pallet is the possibility of liquid becoming in the event of a breakthrough of the siphon wiring outside the channels, which leads to the brewing of equipment located on the pallet and transport carriages. The purpose of the invention is to reduce the possibility of metal release in case of siphon wiring breaks out of the channel limits. I The goal is to achieve that in the siphon metal casting tray, made in the form of metallic miHibi, having a nest for the center and channels extending from it for laying refractory siphon wiring, each channel is made in a cross section of T-shaped, we and equipped with a removable metal plate placed in the upper broad part of the kangsha. The pallet is provided with protruding sides along the perimeter, in one of which a window is made. FIG. 1 shows a siphon tray for metal casting, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - channel, cross section; in fig. 4 - channel overlap. The pallet is made in the form of a metal plate 1 having a nest 2 for the center plate and the channels 3 extending from it for laying-refractory siphon wiring. The channels 3 are T-shaped, and the metal plate is made with protruding flanges 4, one of which is made with a window 5. The plates 7 are placed on the upper recess 6 of the channel 3. The tray is prepared for casting as follows. Siphon wiring is laid in channels 3, and dry fine-grained sand of fraction 0.03-0.8 mm is poured between the walls of the channel and wiring. After filling the channel on the upper recess 6 stack metal plate 7 flush with the upper part of the metal plate. Then on the metal plate 1 set the center and the mold. In the process of casting metal, the siphon wiring is subjected to thermal stress, which leads to the formation of cracks. The metal, the passage through the cracks, interacts with the metal plate and plate, freezing, while preventing the metal plate from reaching the surface. In the case of metal breakthrough in siphon wiring or emergency casting, the metal falls on the pallet, the protrusion of the board prevents

fill trucks and railways. The metal on the metal plate through the window is poured into the container.

This pallet helps prevent metal from reaching the surface of the metal plate;

reduce the service life of the equipment and reduce the labor costs of eliminating accidents siphon wiring. The economic effect per ton of finished steel 5 is 0.20-25 p due to a reduction in the specific consumption of replaceable equipment f-f

/ ore on 1.3-1.4 kg / t of steel.
