Special shaped steel is the abbreviation of complex and special-shaped section steel, which belongs to a kind of section steel and is different from the name of simple section steel. According to the different process, it can be divided into hot rolled profiled steel, cold drawn profiled steel, cold formed profiled steel, welded profiled steel and so on. Generally, profiled steel refers to hot rolled profiled steel. Hot rolled section steel is a kind of hot rolled section steel which can distinguish square steel, round steel, flat steel and common shape[ 1]
Introduction editing voice
Profile steel is one of the four kinds of steel (profile, line, plate and pipe), which is widely used. According to the section shape, section steel can be divided into simple section steel and complex or special section steel (special section steel). The characteristic of the former is to make a tangent through any point around the cross section, which is generally not intersected in the cross section. Such as: square steel, round steel, flat steel, angle steel, hexagonal steel, etc; The common profiled steels include hot rolled window frame steel, plowshare steel, hot rolled section steel for automobile wheel retaining ring, hot rolled section steel for track plate, hot rolled section steel for automobile wheel rim, rail, ball flat steel for shipbuilding, cable coil steel, scraper steel, etc[ 1]
Basic knowledge of special shaped steel
Classification of steel: according to chemical composition, steel is divided into carbon steel and alloy steel; According to the use of steel can be divided into structural steel, tool steel and special performance steel.
Q235 steel is the main carbon steel used in construction engineering. In steel structure, all kinds of special-shaped steel, steel plate and steel pipe are mainly rolled by Q235 steel[ 1]

Due to the particularity and singleness of the use of special-shaped steel, the requirement of precision is often higher than that of simple section steel, which has higher requirements for the capacity of the equipment. Because of its complex cross-section shape, especially for special-shaped steel in many special occasions, there is even little experience to learn from, so the difficulty of pass design and production is much higher than that of simple cross-section steel. Therefore, the production cost of special-shaped steel is higher than that of simple section steel. Because the shape and size of special-shaped steel are very different, many of them are special for a certain industry or specific occasions, so the market demand for a single variety is often not very large. Therefore, the scale of special-shaped steel production system is often not very large.
