A continuous casting mill is a special type of rolling mill used to solidify steel into "semi-finished" billets, blooms or slabs, which are then rolled in a finishing mill.
Casting re-melts the alloy material and transforms the alloy in its liquid state into cast strip or bars. Alloys are often preferred over single element metals, especially for solder preforms, because they have different melting points, specific electrical conductivity properties or improved thermal expansion values.
The casting process requires a starting bar to which the liquid metal is attached; once the starting bar is in place, it slowly pulls the liquid metal out through the mould to form a cast strip or bar with the appropriate cross-sectional dimensions. The result is a homogeneous bar or rod ready for subsequent processing. Prior to the introduction of continuous casting in the 1950s, steel was poured into fixed moulds to form 'ingots'. Since then, "continuous casting" has been developed to improve yield, quality, productivity and cost efficiency.
Precision Stainless Stel Pipe Production Line
* An intermediate ladle, located above the mould, which feeds the liquid steel to the mould at a defined rate
* A primary cooling zone or water-cooled copper mould through which the steel is fed from the intermediate ladle to
produce a solidifying shell strong enough to hold the strands in place when they enter the
the secondary cooling zone to maintain the strand shape
*The secondary cooling zone is associated with a closed section located below the mould and
the strand, which is still mostly liquid, passes through this section and is sprayed with water or water and air to further solidify the strand
* A cutting device (torch or mechanical scissors) to cut the solidified strand into pieces for removal and further processing
A tube mill forms tubes and pipes by obtaining a continuous strip of material and rolling it continuously until the edges of the strip meet at a welding station. At this point, the welding process melts and fuses the edges of the tube together and the material leaves the welding station as a welded tube. The basic components include an uncoiler, straightener, shear, forming section, fin pass section, welder, ID and/or OD planer, sizing section, cut-off and stacker or jumping table.
Each pass of each section consists of an upper and lower shaft containing a roll die tool that gradually forms the strip into a circle or square (in the case of square/welded square mills). This gradual forming process is often referred to as inserting.
Tube forming metal can be used in many different industries such as gas, water and sewage pipes, structural, industrial and scaffolding pipes. In addition, your tube mill can produce hollow, rectangular, round or square pipes.
