Strip steel is extremely versatile, mainly used in the automotive industry, machinery manufacturing industry, construction, steel structures, daily hardware and other fields, and is the raw material for cold-rolled strip, cold-formed steel, welded steel pipes and other steel. Strip steel has the advantages of high dimensional accuracy, good surface quality,…
Inspection and analysis of the mechanical and technical properties, metallographic organization and chemical composition of steel is an important means to ensure the quality of the product, in order to ensure the safe and reliable use. The mechanical and process performance tests mainly include various hardness tests, tensile tests, compression…
There are two main ways to transport hydrogen at this stage, one is to transport hydrogen in long high-pressure pipe trailers and the other is to transport hydrogen by pipeline. Nowadays, the whole length of the hydrogen pipeline has been built around the world about 4670 km, among which about…
Process Flow Advantage Shortage Be suitable for Electric furnace Electric furnace – Secondary refining -CCM – Rolling Alloy elements can be fully utilized Able to accurate control hot liquid temperature for a long time. Smelting period is long and high cost. Adaptable to produce a small batch, multi-specifics and high…
Electrical steel plate, also known as silicon steel sheet, refers to a very low carbon content (after annealing, carbon content in 0.005% below) of ferrosilicon soft magnetic alloy silicon content is generally 0.5%-4.5%. Adding silicon to iron can increase its resistivity and permeability. With the characteristics of low iron loss…
The energy cost of steel plant accounts for about 25%-40% of the total production cost. There is a considerable gap between the energy cost of excellent energy-saving enterprises and that of lagging enterprises, and the energy efficiency of steel mills relates to the benefit and competitiveness of enterprises. The saving-energy and…
Metal composite plates are used in petrochemical, coal chemical, fluorine chemical, fine chemical, acetic anhydride, PTA, chlor-alkali, salt production, metallurgy, medicine, electric power and many other fields. Composite plates are made of a base layer (e.g. carbon steel) combined with a laminate layer (special corrosion resistant or other precious metal…
Hot rolled sections are characterized by large production scale, high efficiency, low energy consumption and low cost. Rolling sections uaually applies the following methods: Ordinary rolling method The 2-hi or 3-hi mill produces steel section, its pass pattern is made of the groove of the two rollers, can produce simple, shaped and longitudinal rolling cycle section section steel.…
Tundish is an important equipment for continuous casting process, its refractory lining mainly includes heat insulation layer, permanent layer and working layer. (1) The main function of the insulation layer is thermal insulation, usually with asbestos board insulation bricks or light castables, aluminium silicate fibre mats, and nano-microporous insulation boards plus…
The geometrical characteristics of the octagonal billet lie between those of a square cross section and a round cross section, with the respective advantages of a square billet and a round billet, the billet leaving the mould has excellent structural rigidity and can significantly restrain the bulging deformation of the shell. Because of…
