Comprehensive Classification
(1) Carbon steel, categorized by purpose, encompasses three main types: carbon structural steel, carbon tool steel, and free-cutting structural steel. Dive deeper into carbon structural steel, further classified into engineering construction steel and machine manufacturing structural steel, each designed to meet specific industry demands.
(2) Based on the smelting process, carbon steel is divided into open hearth steel and converter steel, each offering distinct characteristics tailored to various industrial needs.
(3) Differentiated by deoxidation methods, carbon steel is categorized into boiling steel (F), killed steel (Z), semi-killed steel (b), and special killed steel (TZ), each providing unique benefits for specific applications.
(4) Based on carbon content, carbon steel is segmented into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25%-0.6%), and high carbon steel (WC > 0.6%), offering varying levels of strength and pliability.
(5) According to steel quality, carbon steel splits into ordinary carbon steel (with higher phosphorus and sulfur content), high-quality carbon steel (with lower phosphorus and sulfur content), advanced high-quality steel, and extra high-quality steel, each engineered for distinct uses.
Diverse Steel Grades and Their Applications:
08F: With a low carbon mass fraction, this steel offers excellent plasticity and low strength, ideal for stamping parts like automobile and instrument housings.
20: Known for its good plasticity and weldability, perfect for low-strength-required parts and carburized components such as hoods, containers, small shafts, nuts, washers, and carburized gears.
45, 40Mn: Delivering superior mechanical properties post-quenching and tempering, these are perfect for high-force mechanical parts including gears, connecting rods, and machine tool spindles.
60, 65Mn steel is characterized by its incredible strength; perfect for crafting a variety of springs, locomotive wheel flanges, and low-speed wheels.
T7, T8: Ideal for parts that endure significant impacts and require robust toughness. Perfect for tools such as sledgehammers, punches, chisels, woodworking tools, and scissors.
T9, T10, T11: Expertly crafted for tools demanding extreme hardness and wear resistance with minimal impact. Ideal for taps, small drills, dies, and hand saw blades.
T12, T13: Engineered for tools resilient to impact, such as files, scrapers, razors, and measuring instruments.
Hot Rolling Defined Hot rolling, as opposed to cold rolling, involves rolling the metal above its crystallization temperature, enhancing its workability and structural integrity.
Unrivaled Advantage:
(1) Hot rolling is a highly efficient process that significantly cuts energy consumption and costs. The increased plasticity and lowered deformation resistance during hot rolling enable substantial deformation, offering a cost-effective manufacturing solution.
(2) The brilliance of hot rolling lies in its ability to significantly enhance the processing performance of metals and alloys. This process artfully breaks the coarse grains present in the casting stage, beautifully heals existing cracks, and skillfully reduces or even eradicates casting defects. The transformation from an as-cast structure to a deformed, superior structure results in an improved processing performance of the alloy, making it more robust and versatile for various applications.
(3) Hot rolling invariably employs large ingots and substantial rolling reductions. This strategic choice not only escalates production efficiency to remarkable heights but also sets the stage for enhanced rolling speeds. Furthermore, it lays down the foundational conditions for achieving continuous and fully automated processes, thereby revolutionizing the rolling industry with its seamless operation.
