Natural mineral containing less than 30% iron. It is the primary ore used in blast furnaces.

A type of cold-rolling mill, the tandem mill imparts greater strength, a uniform and smoother surface, and reduced thickness to the steel sheet. Unlike the original single-stand mills, a tandem mill rolls steel through a series of rolls (generally three to five in a row) to achieve a desired thickness and surface quality.

A group of tanks at a well site used to store oil prior to sale to a pipeline company.

The pouring of molten metal from a ladle into an ingot mould. The economic advantages of continuous casting over ingot casting mean that the ingot-route process has largely been superseded for high volume production of steel

Heating to 200-500°C with the aim of making hardened steel tougher and less susceptible to cracking.

A second cold rolling for coil in which the reduction in gauge is minimal. Can be used to achieve a bright finish.

Sheet steel coated with a mixture of lead and tin. Terne principally is used in the manufacture of gasoline tanks, although it also can be found in chemical containers, oil filters, and television chassis.

The thermal efficiency of a fuel cell system is the ratio between the output of the system (as heat and power) and the heat-content of the input fuel.

This is where molten steel is continuously cast into slabs. These are either allowed to cool before reheating for hot rolling, or kept hot in a nearby furnace before being sent on to the hot mill. 

This describes gas that has been produced from a relatively impermeable reservoir rock. Hydrocarbon production from tight reservoirs can be difficult without stimulation operations.

Tin-free steel is a chromium-coated, corrosion-resistant steel which, like tinplate, is used for food and other packaging applications. The coating is applied to a cold-rolled, low-carbon steel coil in a continuous electrolytic process using chromic acid. The result is a very thin layer of chromium and chromium oxide. 

This is thin sheet steel with a very thin coating of metallic tin. Tin plate is used primarily in canmaking. It has good corrosion resistance and food compatibility – although many products require a thin coating of lacquer to maximise the shelf life of the contents. 

The ton is a unit of weight, but takes various forms. A metric ton (usually written tonne) is 1,000 kilograms (kg) and is the most widely used. A long ton is 2,240 pounds (lb).

Carbon and alloy steels that have high resistance to abrasion. As the name suggests this product group is especially well suited to the manufacture of tools (including stamping dies, shear blades, and hand tools such as spanners, machine tool bit holders etc).

Cylindrical railcar lined with bricks and used for transporting the hot metal from the blast furnace to the steel shop (steelworks).
