Lip-axis pouring is often used on molten metal pouring systems where there is a need to automate the process as much as possible and the operator controls the pouring operation at a remote distance. For bottom pour ladles, a stopper rod is inserted into a tapping hole in the bottom of the ladle. To pour metal the stopper is raised vertically to ...
From the ladle, the hot metal is transferred via a refractory shroud (pipe) to a holding bath called a tundish. The tundish allows a reservoir of metal to feed the casting machine while ladles are switched, thus acting as a buffer of hot metal, as well as smoothing out flow, regulating metal feed to the molds and cleaning the metal (see below).
It is used to feed molten metal into an ingot mould to avoid splashing and give a smoother flow. The tundish allows a reservoir of metal to feed the casting machine while ladles are switched, thus acting as a buffer of hot metal, as well as smoothing out flow, regulating metal feed to the moulds and cleaning the metal.
The molten steel had alloying metals added; after sampling and satisfactory laboratory confirmation of the molten metal's composition the furnaces were tapped out into preheated bottom-pouring ladles, which held some 20 tons of steel each.
The car carries a metal ladle, typically torpedo-shaped (with two pointed ends), from one location to another for processing molten metal. [2] [3] It can also be called a molten steel transporter, a bottle car, [4] or a Tundish transfer car. The ladle is placed on a rail car but can be removed to pour out the molten metal.
The pressure is applied to the top of the pool of liquid, which forces the molten metal up a refractory pouring tube and finally into the bottom of the mold. The pouring tube extends to the bottom of the ladle so that the material being pushed into the mold is exceptionally clean.
