Abstract
The invention discloses a wear-resistant material quenching process. A quenching furnace in a heat treatment workshop is provided with six temperature areas: I and II areas with both temperatures of 750 DEG C, III and IV areas with respective temperatures of 880 and 870 DEG C, and V and VI areas with respective temperatures of 890 and 880 DEG C; the quenching process is as follows: workpieces are preheated in the I and II areas, are continuously heated in the III and IV areas, and are discharged from a furnace for water-spraying quenching after the heat preservation, that is, the workpieces are discharged from the furnace for quenching after three circulating beats; the average time of the furnace access circulating beats is 25 minutes; the heat preservation time of the V and VI areas is 25-35 minutes; and the total time in the furnace is 70-80 minutes. The wear-resistant material quenching process, provided by the invention, enables the hardness of wear-resistant materials to become stronger through the subarea and subsection process operation.
Description
Technical field
The present invention relates to a kind of high-abrasive material quenching technology.
Background technology
Metal works be heated to a certain proper temperature and keep for some time, immersing the metal heating processing technology of cooling fast in quenching media immediately.Conventional quenching media has salt solution, water, mineral oil, air etc.Quenching can improve hardness and the wear resistance of metal works, is thus widely used in various work, mould, measurer and requires the part (as gear, roll, carburized parts etc.) of surface abrasion resistance.Coordinated with the tempering of differing temps by quenching, the intensity of metal, toughness and fatigue strength can be increased substantially, and the cooperation (comprehensive mechanical performance) that can obtain between these performances is to meet different service requirementss.And high-abrasive material, its performance is more by the impact of quenching technology.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of high-abrasive material quenching technology.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of high-abrasive material quenching technology, the quenching furnance of heat treatment department is provided with 6 warm areas: I, IIth district, and temperature is all set to 750 DEG C, III, IV district, and temperature is set to 880,870 DEG C respectively, V, VI district, and temperature is set to 890,880 DEG C respectively; Quenching process: workpiece is in I, II district's preheating, and III, IV district continues heating, to come out of the stove spray quenching after the insulation of V, VI district, and namely workpiece is come out of the stove quenching after 3 circulation beats; Turnover stove circulation beat time average is 25 minutes, and V, VI district's soaking time is 25 ~ 35 minutes, and in stove, total time is 70 ~ 80 minutes.
Beneficial effect of the present invention:
The invention provides high-abrasive material quenching technology, by the technological operation of subregion segmentation, make high-abrasive material hardness stronger.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
