Embodiment
By steel scrap, carburant, ferrochrome, copper and iron, ferromanganese, ferrosilicon and trace rare-earth, Hybrid Heating melts in electric furnace first, When liquid steel temperature reaches 1580~1600 DEG C, deoxidation is added, the chemical composition of molten steel in stove and its mass fraction are adjusted to C =0.90~1.3%, Cr=1.5~2.5%, Mn=11~14%, Mo=0.8~1.2%, Cu=0.6~0.80%, S< 0.04%, P<0.05%, surplus is Fe and inevitable micro impurity element.The height of silicone content, impact toughness is influenceed It is larger, therefore should remove the limit, to be advisable no more than 0.5%.Low-phosphorous low-sulfur is most basic requirement, because high manganese content rises naturally To desulfidation, therefore it is most critical to drop phosphorus, tries to make phosphorus be less than 0.05%.Chromium is to improve wear resistence, typically left 2.0% It is right.
Wherein, manganese Mn, it is main intensified element, is partially soluble in ferrite, strengthens matrix, remaining Mn amount generation Mn3C, it With Mn3The mutual phased solns of C, (FeMn) is generated in steel3C-type carbide, Mn make A3Point reduces A4Point rises, and S, E point move to left, so as to Increase the quantity of steel medium pearlite.Because Mn reduces γFePhase transition temperature and M3Temperature, reduce austenite decomposition (carbide precipitate) Speed, greatly improve the quenching degree of steel.
Wherein, chromium Cr, it is one of the chief elements in abrasion-resistant stee, it forms alloyed cementite with the carbon in steel and iron (FeCr)3C and alloy carbide (FeCr)7C3, can partly dissolve in solid solution, strengthen matrix, improve the quenching degree of steel, especially It can greatly improve quenching degree with manganese, the reasonably combined use of silicon.Cr has larger resistance to tempering, can make the standby of thick end face Part performance is uniform.In middle alloy abrasion resistant steel the content of chromium should not too high otherwise can cause quenching, retained austenite in tempered structure Body increase.General control is between 1.5%~2.5%.
Wherein, molybdenum Mo, in alloy wear-resisting cast steel can effectively thinning microstructure, during heat treatment can strong inhibition austenite to Perlitic transformation, stable heat-treated sturcture, addition molybdenum can be increased sharply its through hardening in alloy abrasion resistant steel in Cr-Mo-Si Property and homogeneity of fault plane prevent the generation of temper brittleness, improve temper resistance, improve impact toughness, the heat resistanceheat resistant for increasing steel is tired Labor performance, but its is expensive, typically according to size and thickness control between 0.8%~1.2%.
Wherein, copper cu, carbide is not formed with carbon, his the copper cu in iron solubility is little, and iron can not be formed continuously Solid solution.The reduction of solubility with temperature of the copper in iron and fall sharply.
Precipitation-hardening can be produced by appropriate heat treatment to act on.Also with nickel similarity, quenching for steel can be improved The electrode potential of permeability and matrix, increase resistance to corrosion.It is more important under the conditions of wet-milling, general control 0.6%~ 0.8%, too high copper is unhelpful to abrasion-resistant stee
Wherein, rare earth can purify crystal boundary with refined cast structure, improve form and the distribution of carbide and field trash, carry The fatigue resistance of high medium alloy steel and antifatigue spalling, and middle alloy abrasion resistant steel is kept enough toughness.
Smelting furnace uses intermediate frequency furnace, first melting carbon steel, and the gravity alloy material such as all kinds of ferromanganese and ferrochrome, copper and iron, ferrosilicon, To enter stove on a small quantity every time several times, noble element is being eventually adding, to reduce scaling loss.Expect that block should be as small as possible, with 50-80mm It is advisable.After melting down, when furnace temperature reaches 1580-1600 DEG C, deoxidation, dehydrogenation, denitrogenation.Deoxidier is necessarily pressed onto to depths in stove. Metal bath surface is now covered tightly with coverture, separates outside air.Calm a period of time is also wanted, oxide, field trash is had abundance Time floats.During this period, the content of manganese and carbon is adjusted with mid-carbon fe-mn in time.
Due to C, Mn contents are higher, and mobility is fine, and temperature height easily column crystal occurs, cause crackle appearance and wearability Difference, so tapping temperature is strictly controlled, typically at 1420 DEG C~1480 DEG C.Before molten steel is come out of the stove, by casting ladle be baked to 400 DEG C with On be very necessary.Do Metamorphism treatment with various trace elements such as rare earths during come out of the stove, be refine primary crystallization must Means are wanted, it is vital that it influences on properties of product.
Modeling Material and coating also should be consistent with molten metal attribute, or use neutral material.If want to obtain primary crystallization The collective of refinement, it is correct, especially lost foam process using the big chromite sand of amount of stored heat, with it radiating will be overcome slow Shortcoming.
The characteristics of manganese steel is that solidification shrinkage is big, and poor radiation, accordingly, shrinkage coefficient takes 2.5%- in technological design 2.7%, casting is more grown up, more answers capping.The deformability of molding sand and core will necessarily get well.
Running gate system is taken open.Multiple scattered ingates introduce at the thin-walled of casting, and into flat and wide loudspeaker Shape, the sectional area at casting are more than the sectional area being connected with cross gate, molten metal is quick smoothly injected casting mold, prevent The only excessive temperature differentials in whole casting mold.Rising head diameter is greater than thermal center diameter, and against thermal center, height is the 2.5-3.0 of diameter Times, it is necessary to unified using hot riser even dead head, allow the high-temperature liquid metal of abundance to carry out sky of the insufficient casting in solidification shrinkage Position.It is also correct that sprue, rising head are located at into eminence (sandbox has 5-8 ° of gradient).Low temperature pours soon as far as possible during cast.One Denier solidifies, and timely fluffing of moulding sand case.Clever designer always excels at leveraging chill, including internal densener in external chill, and it was both refined Primary crystallization, shrinkage cavity and porosity is eliminated, improve product yield again, certainly, suitable dosage and specification should consider.It is interior Chill is clean, meltable, and dosage to be advisable less.The three-dimensional dimension of external chill and the three-dimensional dimension of cooling thing are 0.6-0.7 times Functional relation.It is too small not work, it is excessive to cause casting to ftracture.Casting wants long-time heat preservation in type, until less than 200 DEG C again Unpack.
During cast, tapping temperature control 1420~1480 DEG C (heat bag drop 20 DEG C), pouring temperature control 1360 DEG C~ 1420℃。
In water-tenacity treatment, when casting temperature is less than 350 DEG C, casting is heated up with the speed less than 80 DEG C/h, After reaching 350 DEG C, 750 DEG C of insulations are warming up to the speed less than 100 DEG C/h, are then warming up to the speed more than 150 DEG C/h It is incubated after 1050 °, then is warming up to 1100 DEG C.Casting after insulation is entered into water quenching, ensures that casting temperature exists before entering water More than 1050-1070 DEG C, water temperature is maintained on less than 30 DEG C before casting enters water, and highest water temperature is no more than 50 DEG C after quenching, quenches The fiery time is less than 1 minute;Water should be not less than 8 times of casting weight.Cold water enters from pond bottom, and warm water flows out from pond top surface. Casting wants three directions ceaselessly to move in pond.
Because manganese steel heat-conductive characteristic is poor, should be paid close attention to when cutting dead head.Preferably casting is placed in water, Cut part is exposed at outside water, is stayed a certain amount of stubble during cutting, is ground off after heat treatment.
From the manganese nickel electrode (D256 or D266 types) of austenite base, specification is elongated,Outer layer coating For alkalescence.Use low current during operation, light current arc, the more layers of small welding bead, the operating method for remaining the few heat of low temperature.One Side is welded while impact, eliminates stress.
Hardness is low after potassium steel workpiece water-tenacity treatment, and workpiece is tight using initial (not yet setting up work-hardened condition) abrasion Weight.In order to overcome this situation, can carry out improving initial hardening processing.There are following two methods.
1. carbonization treatment method.Workpiece is in oxidizing atmosphere or containing H after water-tenacity treatment2And H2Heated in O atmosphere, take off surface Carbon, certain thickness Malpighian layer is obtained, improves case hardness, the starting rate of wear of workpiece can be greatly lowered, extended Service life.
2. process hardening process.Workpiece after water-tenacity treatment, chiso-mallet, shot-peening are carried out to it before its use or is rolled etc. to add Work, one layer of work hardening layer is artificially caused, to improve initial hardness.
Casting after water-tenacity treatment is subjected to temper, temperature at 240~250 DEG C, tempering time in more than 6h, For adding Cr potassium steel, temper can be obviously promoted the orderly expansion of C-Mn clusters, pass through the random of these ordered domains With distribution and the top bundle that increases corresponding mistake acts on, so as to improve its anti-wear performance.
