Technical field
The invention belongs to the cast steel field, relate to wear resistance castings, especially a kind of martensite wear-resistant steel and manufacture method thereof.
Background technology
Existing wearable cast steel mainly contains high mangaenese steel and low alloy steel.High mangaenese steel is a kind of austenitic steel, initial hardness is low, only in greater impact load or connect and separate under the stress, competence exertion surface working hardening phenomenon and play attrition resistant effect, but in actual condition, technology more than 90% all can not make high mangaenese steel effectively harden, and makes that the actual wear resistance of high mangaenese steel can not be satisfactory.
Low-carbon alloy martensite wear-resistant steel mostly is Cr, Mo in external at present, Ni is a steel alloy, and thermal treatment process adopts to quench and adds the technology of low-temperaturetempering, to obtain high strength, high rigidity and certain flexible alloy property.The research of low-carbon alloy wearable cast steel and application started from after the eighties in 20th century in China, a series of achievements have been obtained, typical steel grade is 30CrMnSiMoNi and Cr5Mo steel, during also to put forth effort to have developed the Si, the Mn that meet China's alloy resource situation for some time be alloy 30Si2Mn.People have recognized that gradually multi-element alloyed is the effective ways that improve wearable cast steel hardening capacity, obdurability and hardness now, thereby wearable cast steel adopts Cr, Mo, Ni, Si, Mn multicomponent alloy both at home and abroad, is used to make wearing pieces such as ball grinding machine lining board, grinder hammerhead, excavator bucket teeth.
By retrieval, find the two piece patent documentations relevant with this patent content, wherein: publication number provides a kind of high-yield-ratio high tenacity casting Martensite Stainless Steel for the Chinese patent of CN1528937, characteristics are to contain in its chemical ingredients: C≤0.06%, Cr 11-16.5%, Ni 3.50-6.0%, Mn≤2%, Mo 0.5-2%, Si＜1%, surplus is Fe and small amount of impurities, impurity comprises Al, [O], [N], [H], S, P, its content is respectively Al＜0.15%, [O]＜0.01%, [N]＜0.03%, [H]≤0.0005%, S≤0.020%, P≤0.025%; Publication number provides a kind of wearable cast steel in microalloy martensite and manufacture method for the Chinese patent of CN1600889, its chemical ingredients is wt%:C 0.25～0.34, Si 0.3～0.7, Mn 1.15～1.65, Cr 0.5～1.0, B 0.0005～0.005, Ti 0.01～0.06, Ce 0.01～0.045, La 0.01～0.035, Al0.01～0.1, S≤0.035, P≤0.035, its microalloying treatment process is earlier to add TiFe in 1600～1610 ℃ in smelting furnace, adds in casting ladle or is inclining to molten steel drop into RESiFe and BFe alloy simultaneously in casting ladle.
This patent content and above-mentioned two pieces of patents have more different.
Summary of the invention
The objective of the invention is to overcome the prior art weak point, a kind of martensite wear-resistant steel and manufacture method thereof are provided, on the basis of middle low-carbon alloy martensite wear-resistant steel, utilize the trace element of reasonable ratio to replace expensive elements such as Mo, Ni, by stable microalloy technology reach or exceed Cr, Mo, Ni is intensity, toughness and the wear resistance of alloy martensite wear resisting steel.
