CHNZBTECH – BEST TRANSFER LADLE MANUFACTURER IN CHINA
A transfer ladle is a container used to carry and pour molten metal, from the furnace to the pouring unit. If you are planning to buy a transfer ladle for your company according to your needs, then you are at the right place. Today, we will tell you about the different types and functions of transfer ladles available in the market and the best ladle manufacturer in China – CHNZBTECH.
WHERE
TRANSFER LADLE IS USED?
Transfer
ladle is often used in foundries, and if it is small, it can be carried by hand
in a container with a handle that resembles a kitchen ladle, and if it is
large, it can carry up to 300 tons of molten metal in a steel mill. Many
non-ferrous foundries use ceramic crucibles for transporting and pouring molten
metal, which is also sometimes called ladle.
TYPES
OF TRANSFER LADLES
Transfer
ladles can be roughly classified into the following three types.
·
Casting ladle
A
casting ladle is a transfer ladle used to pour molten metal into a mold to make
a casting.
·
Transport ladle
A transport ladle is a transfer ladle used to convey large amounts of molten metal from one process to another. Typically, a transfer ladle is used to convey the melt from the primary melting furnace to the holding furnace or automatic pouring unit.
·
Processing ladle
A
processing ladle is a ladle used in processes that are carried out in the ladle
to change some of the properties of the molten metal. A typical example is the
conversion of cast iron into ductile iron by adding various elements to the
transfer ladle.
FUNCTIONS
OF TRANSFER LADLE
Various
modifications may be made to the basic design of these ladles to improve the
ladle's utility for that particular practice. In addition, the common necessary
functions are:
·
Possesses heat
insulation properties so that heat is not released or radiated from molten metal.
·
Thermal insulation
to prevent the surroundings from becoming hot and to maintain the safety of the
surroundings.
·
Strong enough to
hold the heavy molten metal.
·
Wear resistance and
spalling resistance against molten metal.
·
Heat resistance and strength
of refractories such as blast furnaces.
· Ease of handling during pouring.
LINING OF TRANSFER LADLES (
Ladles
are lined with a refractory lining unless they are used with alloys with very
low melting points. It is to prevent the steel container from being damaged
when transporting high-melting-point metals using a ladle.
There
are many different materials for refractory linings, and the correct choice is
highly dependent on each foundry's practices. Traditionally, ladles were lined
with refractory bricks before casting, but refractory concrete is replacing
this in many countries.
Foundry
ladles are usually valued more for their working capacity than for their
physical size. A hand-held ladle has a long handle to keep the heat of the metal
away from the person holding it. Its capacity is limited to what a person can
safely handle.
Large
ladles are commonly called geared crane ladles. Its capacity is generally
determined by the function of the ladle. A small hand-held ladle may be a crucible
fitted with a carrier. However, the casting ladle found in most foundries is
equipped with a hoisting device so that the container can be transported by
overhead crane, monorail, etc., and is usually made of steel with a mechanism
that rotates the container with a gearbox. The gearbox can be manually operated
or power controlled.
HOW
TRANSFER LADLES ARE DRIVEN?
Ladles
are sometimes driven on wheels or on special ladle transfer cars, such as in
steel mills, to transport very large quantities of molten metal. Others are
transported suspended from overhead cranes and tilted using a separate hoisting
device on the ceiling.
POURING
DESIGN OF TRANSFER LADLE
There
are two types of pouring design of ladle: "lip pour tilting type" and
"bottom pour bottom pouring type".
· In the lip pour method, the molten metal is poured
out by tilting the ladle, like pouring water from a jug.
· The bottom pour type has a pour spout at the bottom of the ladle and a stopper rod inserted. For pouring metal, the stopper is vertical, allowing the metal to pour out the bottom of the ladle. To stop pouring, insert the stopper rod back into the drain port.
Large
ladles, such as those used in the steel industry, use a slide mouth below the
tap hole.
Some
ladles are open at the top, while others have a cover. Small ones are often
open. However, for efficiency considerations, a lid seems necessary.
Those
with covers (some of which can be removed) have dome-shaped lids to retain the
radiant heat, allowing the heat to escape more slowly than the open-top
types.
Small ladles often do not have a cover, but ceramic fiber cloth or the like can be substituted.
