Description

A kind of ultra-thin alloy strip of high-carbon steel and preparation technology thereof
Technical field
The invention belongs to high-carbon steel preparing technical field, particularly a kind of ultra-thin alloy strip of high-carbon steel and preparation technology thereof.
Background technology
High-carbon steel often claims tool steel, and phosphorus content, from 0.60% to 1.70%, can harden and be tempered.Hammer, crowbar etc. is by carbon containing The steel making of amount 0.75%；Cutting element such as drill bit, screw tap, reamer etc. is by the steel making of phosphorus content 0.90% to 1.00%.High-carbon Steel after appropriate heat treatment or Cold-draw Hardening, has high intensity and hardness, high elastic limit and fatigue limit (especially The notch fatigue limit), cutting ability still can, but welding performance and cold plastic deformation ability.Owing to phosphorus content is high, hold during shrend It is easily generated crackle, so using double quenching (shrend+oil is cold) more, small bore part many employings oil quenching.This kind of steel is typically being quenched Through average tempering or normalizing or use under surface hardening state after fire.Mainly for the manufacture of spring and wear part.Carbon element work Tool steel is the high-carbon steel being substantially added without alloy element, is also that in tool steel, cost is relatively low, cold and hot working good, uses The steel grade that scope is wider.Its carbon content, 0.65 one 1.35%, is used exclusively for the steel of tools.
High-carbon steel typically has: 1, can obtain high hardness (HRC60 1) and preferable wearability after heat treatment. 2, under annealed condition, hardness is moderate, has preferable machinability.3, raw material is easy to get, and production cost is low.
Equally, high-carbon steel there is also defect: 1, thermohardening is poor, when cutter operating temperature more than 200 DEG C time, its hardness and Wearability drastically declines.2, quenching degree is low.During shrend, the diameter of complete through hardening is typically only 15 1 18mm；Quench completely during oil quenching Saturating maximum gauge or thickness (95% martensite) are only about 6mm, and yielding cracking.The hardness of high-carbon steel, intensity are main Depend on the carbon amounts of solid solution in steel, and improve with the increase of solid solution carbon amounts.When solid solution carbon amounts is more than 0.6%, after quenching, hardness is not Being further added by, superfluous carbide increasing number, the wearability of steel is increased slightly, and plasticity, toughness and elasticity decrease. To this end, often select different grades of steel according to use condition with to intensity, the toughness coupling of steel.Such as, stress is manufactured little Spring or spring formula part, 65 steel of optional relatively low carbon amounts.General high-carbon steel can use electric furnace, open hearth, oxygen coverter to produce.Requirement Quality is higher or electric furnace smelting can be used to add vacuum consumable or electroslag remelting during very special quality.When smelting is melted, the strict chemistry that controls becomes Point, particularly sulfur and the content of phosphorus.For reducing segregation, improving equal orientation performance, steel ingot can carry out high temperature diffusion annealing (to tool steel Particularly important).During hot-working, hypereutectoid steel stop forge (rolling) temperature requirement low (about 800 DEG C), forging rolling should be avoided thick after becoming a useful person The precipitation of net carbide, it should be noted that slow cooling below 700 DEG C, in case thermal stress causes crackle.Heat treatment or hot procedure In skin decarburization to be prevented (particularly important to spring steel).To have enough compression ratios during hot-working, with ensure steel quality and Serviceability.High-carbon steel-welding procedure high-carbon steel is high due to phosphorus content, and welding performance is very poor.It is welded with following features:
1, poor thermal conductivity, produces the significant temperature difference between weld zone and non-heating part, when molten bath quick refrigeration, in weld seam The internal stress caused, it is easy to form crackle.2, more sensitive to quenching, Jin Feng district easily forms martensitic structure.Due to group Knitting the effect of stress, Shi Jinfeng district produces cold crack.3, owing to welding the impact of high temperature, crystal grain is grown up soon, and carbide easily exists Gathering on crystal boundary, grow up, make weld seam fragile, strength of welded joint reduces.4, it is more prone to than medium carbon steel during high-carbon steel welding Fire check.High-carbon steel and steel, high-carbon steel is a classification of steel, it should be that high-carbon steel and medium carbon steel are the most right.Although high-carbon steel is hard Degree is high but matter is crisp, easily snaps off, but the general structural member of the soft good toughness of medium carbon steel matter is all the such as 40#45# steel of carbon steel Be the steel of the most frequently used steel automotive frame doing axle be exactly the structural alloy steel of 16Mn.Should be better with medium carbon steel as vehicle frame Or it is better with structural alloy steel.
At present, utilize the ultra-thin alloy strip that high-carbon steel produces, generally also exist: the easy broken belt of thin material, template is poor, hardness is inadequate Etc. problem.
More than in view of, the present invention proposes a kind of ultra-thin alloy strip utilizing high-carbon steel to produce, and not only retains each of high-carbon steel Plant high-performance, and the alloy strip prepared is ultra-thin, hardness big, be difficult to broken belt etc..
