Characteristics

Grade
Standard/ ●Characteristics and scope of application
After heat treatment and cold drawing hardening, the strength is high and it has certain toughness and plasticity. Under the same surface condition and complete hardening, the fatigue limit is equivalent to that of alloy springs. However, poor hardenability is mainly used for smaller-sized springs, such as pressure-regulating, speed-regulating springs, force-measuring springs, round and square spiral springs on general machinery, or springs drawn into steel wires for small machinery.

Annealing specifications
Traditional periodic spheroidizing annealing process annealing temperature holding furnace is cooled to temperature and then kept warm After it is cool enough, take it out of the oven and air-cool it. The production efficiency is low, the oxidation and decarburization rate reaches the surface hardness and the elasticity does not meet the requirements. Incomplete annealing new process annealing temperature holding furnace is cooled down to air cooling after being discharged. Tensile strength, elongation, hardness, metallographic structure, spheroidized pearlite, and a small amount of point-like pearlite shorten the production cycle and save energy.
New annealing process
The traditional annealing process is to keep the annealing temperature warm and then cool it in the furnace and then air-cool it out of the furnace. The new annealing process annealing temperature insulation furnace is cold enough to keep it warm. After the furnace is cooled to the furnace, it is cooled out of the furnace pile or put into the insulation pit for slow cooling. The metallographic structure meets the requirements. The pearlite structure grade is preferably about 1 grade. This process improves efficiency.
Heat treatment
Low alloy round steel must have high elastic limit and high yield ratio to avoid permanent deformation of spring steel under high load. It also requires good hardenability and low deformation. Carbon sensitivity greatly reduces the elastic limit and has good surface quality. It is easy to process and form in hot and cold conditions and has good heat treatment processability.
The heat treatment process of hot forming spring steel for springs formed in a hot state. Most spring steel formed by this method combines hot forming and heat treatment, while spiral spring steel is mostly heat treated after hot forming. The heat treatment method of this kind of spring steel is quenching, medium temperature and tempering. After heat treatment, the structure becomes tempered trotenite. This kind of organization has high elastic limit and yield limit and has certain toughness.
Team members broke through the original conventional control ideas and adopted new concepts and methods to innovatively develop stability control technology. They based on the characteristics of Baosteel's hot continuous rolling production process to deal with rolling breakage, which is most likely to occur in this second. Carefully analyze the formation mechanism of problems such as reducing roll damage and tail deviation. After more than 10 years of software program development, tracking, testing, evaluation, and analysis to determine reasonable process parameters, we finally successfully developed a finishing roll damage prevention technology. Baosteel's unique hot continuous rolling strip tail stability control technology, such as roll damage early warning technology, and other optimized conventional auxiliary processes such as tail intermediate wave control technology, form a complete set of low alloy round steel heat treatment technologies. The continuous rolling tail stability control technical solution has steadily improved the production capacity and quality control level of Baosteel's high value-added thin-specification low-alloy round steel. The number of production line breakages and tail flicks and unplanned intermediate products have been significantly reduced. Roll consumption has been significantly reduced. Unplanned shutdowns have been significantly reduced. Reduce new product specifications and continuously expand key technical indicators to reach international leading levels.
Uses
The strength, hardness, elasticity and hardenability of steel plates are higher than those of steel plates. They are prone to overheating sensitivity and temper brittleness. Water quenching has a tendency to form cracks. The machinability in the annealed state is acceptable, but the cold deformation plasticity is low and the weldability is poor. Helical springs and spring washers and spring rings with medium-loaded leaf springs up to diameter. High wear-resistant parts such as grinder spindle spring chucks, precision machine tool screw rods, cutters, spiral roller bearings, collars on railway rails, etc.
