1.Long products
A type of finished rolled steel product like rail and steel bars.
2.Low-carbon steel
Low-carbon steel is manufactured using technologies and practices that result in the emission of significantly lower emissions than conventional production.
3.Mechanical tubing
Welded or seamless tubing produced in a large number of shapes to closer tolerances than other pipes.
4.Oil country tubular goods (OCTG)
Pipe used in wells in oil and gas industries, consisting of casing, tubing and drill pipe. Casing is the structural retainer for the walls; tubing is used within casing oil wells to convey oil to ground level; drill pipe is used to transmit power to a rotary drilling tool below ground level.
5.Open hearth process
A process for making steel from molten iron and scrap. The open hearth furnace has a shallow hearth and roof that help to remove impurities from the molten iron. The flame and gases pass across the top of the enclosed hearth, heat being reflected down onto the material in the hearth. This process has been replaced by the basic oxygen process in most modern facilities.
6.Pellets
An enriched form of iron ore shaped into small balls.
7.Pickling
Using chemicals to remove the scale from finished steel.
8.Pig Iron
The product that results from smelting iron ore with a high-carbon fuel such as coke.
9.Plate
A flat-rolled product from slabs or ingots of greater thickness than sheet or strip.
10.Refining stand
A stage in the process of making crude steel, during which the crude steel is further refined (i.e. most residual impurities are removed) and additions of other metals may be made before it is cast.
