Hot rolled coil products with high strength, good toughness, easy processing and good weldability and other excellent properties, are widely used in cold rolled substrate, ships, automobiles, Bridges, construction, machinery, oil pipelines, pressure vessels and other manufacturing industries. Hot rolled coil deep processing is mainly used in cold rolled coil substrate, hot rolled pickling plate and hot rolled galvanized plate, etc. Its application is mainly hot rolled thin coil thickness ≤3.0mm. Cold-rolled coil substrate is one of the main uses of hot-rolled coil. The application of hot rolled coil after cold rolling mainly includes cold rolled commercial coil and deep processing products such as coating plate, color coated plate and electrical steel. The demand for hot rolling pickling coil is mainly concentrated in the automobile industry, compressor industry, machinery manufacturing industry, spare parts industry, fan industry, motorcycle industry, steel furniture, hardware accessories, electric cabinet shelves and stamping parts of various shapes. For example, the automotive industry needs hot-rolled pickling coil for parts, such as car subframe, wheel wheel hot-rolled coil deep processing is mainly used in cold-rolled coil substrate, hot-rolled pickling plate and hot-rolled galvanized sheet, its application is mainly the thickness of 3.0mm or less hot-rolled thin coil.

Structural steel is one of the most important uses of hot rolled coil, the main uses include building steel structure, machinery industry, automobile, oil and gas and other industries. In addition to the direct use of hot-rolled structural steel to make steel structure frames, the construction industry also uses a large number of hot-rolled coil plates as the base material to make cold-formed steel and welded steel pipes. The cold formed steel replaces the formed steel, which changes the single defect of the form and size of the formed steel. Cold-formed steel products include cold-formed square pipe, rectangular pipe and so on. Welded steel pipes include straight seam electric welded steel pipes, automobile pipes, deep well water pump electric welded steel pipes, mineral fluid transfer electric welded steel pipes, metric welded pipes, oil and gas pipeline spiral seam submerged arc welded steel pipes, these products are used in automobiles, container railways, elevators, chemical industry, petroleum, refrigeration, food, machinery, nuclear power, textile machinery, highway guardrail, road Light poles, medical, furniture, hotel facilities, leisure products and other industrial and civil industries.

The hot continuous rolled steel strip with atmospheric corrosion resistance, sulfuric acid dew point corrosion resistance and seawater corrosion resistance, as well as the transverse cut steel plate and the longitudinal cut steel strip are mainly used for the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.

Ferroalloy is one of the essential and important raw materials in steel industry and mechanical casting industry. With the continuous and rapid development of China's iron and steel industry, the variety of steel is expanding and the quality is improving, and the ferroalloy products are put forward higher requirements, and the ferroalloy industry is increasingly becoming the relevant technology and supporting engineering of the iron and steel industry. Their uses, outlined below, are as deoxidizers, as alloying agents, as inoculants for cast nucleates, as reducing agents, and for other purposes. Ferroalloys are also being used more and more widely in the non-ferrous metallurgy and chemical industries. For example, low and medium carbon ferromanganese is used in the production of welding rods; Silicon aluminum alloy for the production of silicon aluminum bright intermediate alloy; Ferrochrome is used in the production of chromiums and chromium-plated anode materials, and some ferroalloys are used in the production of high temperature resistant materials.
