Classification
(1) According to the purpose, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel and free-cutting structural steel, and carbon structural steel is further divided into engineering construction steel and machine manufacturing structural steel;
(2) According to the smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi-killed steel (b) and special killed steel (TZ);
(4) According to the carbon content, carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC>0.6%);
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (higher phosphorus and sulfur content), high-quality carbon steel (lower phosphorus and sulfur content) and advanced high-quality steel (lower phosphorus and sulfur content) ) and extra high-quality steel.
Common steel grades and uses:
08F, low mass fraction of carbon, good plasticity, low strength, used for stamping parts such as automobile and instrument housing;
20. Good plasticity and weldability, used for parts with low strength requirements and carburized parts, such as hoods, welding containers, small shafts, nuts, washers and carburized gears, etc.;
45, 40Mn, after quenching and tempering, the comprehensive mechanical properties are good, and it is used for mechanical parts with large force, such as gears, connecting rods, machine tool spindles, etc.;
60, 65Mn steel has high strength; it is used to manufacture various springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Make parts that withstand a certain impact and require toughness. Such as sledgehammers, punches, chisels, woodworking tools, scissors.
T9, T10, T11: Manufacturing tools that require high hardness and high wear resistance with low impact. Such as taps, small drills, dies, hand saw blades.
T12, T13: Make tools that are immune to impact. Such as files, scrapers, razors, measuring tools.
Hot rolling is relative to cold rolling. Cold rolling is rolling below the crystallization temperature, while hot rolling is rolling above the crystallization temperature.
Advantage:
(1) Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the metal deformation.
(2) Hot rolling can improve the processing performance of metals and alloys, that is, the coarse grains in the casting state are broken, the cracks are healed significantly, the casting defects are reduced or eliminated, the as-cast structure is transformed into a deformed structure, and the processing performance of the alloy is improved.
(3) Hot rolling usually uses large ingots and large rolling reductions, which not only improves production efficiency, but also creates conditions for improving rolling speed and realizing continuous and automation of the rolling process.
