Billet Caster

BILLET CASTER/CONTINUOUS CASTING

Professional steelmakers regard GROWMECH billet casters as the best casting machines capable of producing excellent billets in any required shape, size and quantity, for subsequent rolling in finishing mills.

We offer compact and quality continuous casting solutions that exceed the requirements of the market based on different design principles. Our billet casters solidify 80- to 175-millimetre squares or rounds.

Continuous Casting

Continuous casting is a process used in manufacturing industry to cast a continuous length of metal.

• Molten metal is cast through a mould.
• The casting takes the two dimensional profile of the mould but its length is indeterminate.
• The casting will keep traveling downward with its length increasing with time.
• New molten metal is constantly supplied to the mould, at exactly the correct rate, to keep up with the solidifying casting.
• Industrial manufacture of continuous castings is a very precisely calculated operation.

Process of Continuous Casting in Growmech Billet Casters.

This casting operation uses the force of gravity to fill the mould and to help move along the continuous metal casting.

• Molten metal is poured into a tundish.
• The tundish is placed about 80-90 feet above the ground level.
• The tundish is constantly supplied with molten steel to keep the process going.
• The whole process is controlled to ensure there is smooth flow of molten steel through tundish.
• The impurities and slag are filtered in tundish before they move into the mould.
• The entrance of the mould is filled with inert gases to prevent reaction of molten steel with the gases in the environment like oxygen.
• The molten metal moves swiftly through the mould and it does not completely solidify in it.
• The entire mould is cooled with water that flows along the outer surface.
• The metal casting moves outside the mould with the help of different sets of rollers.
• While one set of rollers bend the metal cast, another set will straighten it. This helps to change the direction of flow of the steel slab from vertical to horizontal.

GrowMech Application

A great tonnage of continuous casting is done using cast steel.

• Metals such as copper, aluminium, grey cast iron s, white cast irons, aluminium bronzes, and oxygen-free copper are also continuous casting
• Metals are cast as ingot for rolling, extrusion, or forging, and long shapes of simple cross section are cast as round, square, and hexagonal rods.

Components

All components are arranged in a vertical line and:

• a straight mould;
• a straight secondary cooling zone;
• vertical strand cutting; and
• six moulds in one line next to one another, and all are fed from the same tundish.
