Torpedo ladle cars are used to transfer molten iron from the iron-making section of the plant to the steel-making section. Under normal conditions, the residence time of the molten iron in the ladle is two to four hours, and the distance traveled is usually less than one-half mile.
Herein, how many types of ladle are there?
The types are: 1. Hand Ladle 2. Shank or Bull Ladle 3. Tea Pot Ladle 4.
Additionally, what is ladle in steel plant?
In steel: The ladle. An open-topped cylindrical container made of heavy steel plates and lined with refractory, the ladle is used for holding and transporting liquid steel.
What is ladle shape?
The most common shape for a ladle is a vertical cone, but other shapes are possible. Having a tapered cone as the shell adds strength and rigidity to the shell. Having the taper also helps when it comes time to remove the refractory lining. However straight sided shells are also fabricated as are other shapes.
What is molten steel?
The molten steel is extracted from the furnace and used in the casting process where the steel is allowed to pass through a set of rolls and water sprays. This rolls the steel to the correct shape and becomes solid. Then the steel is flattened and cut at required dimensions, which forms slabs, billets, and blooms.
What is the material of ladle?
In modern times ladles are usually made of the same stainless steel alloys as other kitchen utensils; however, they can be made of aluminium, silver, plastics, melamine resin, wood, bamboo or other materials.
What is the use of tundish in the steel plant?
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.
What is torpedo in steel plant?
Torpedo cars are shaped ladles on rails, used to transfer molten iron from the blast furnace to the steel making facility. These cars are lined with protective refractory bricks which can become worn by continuous use.
