Abstract
The invention provides a quenching process of medium carbon alloy steel. The quenching process comprises the following steps: (1) heating the medium carbon alloy steel to 600-650 DEG C along with a furnace, preserving heat for 3-4 hours, heating to 820-960 DEG C and preserving heat for 3-5 hours; (2) immediately putting a workpiece discharged from the furnace into water for quenching, wherein the workpiece is kept in the water for 60-90 seconds; and (3) preserving heat for 2 hours at 300-350 DEG C, discharging the workpiece from the furnace and carrying out air cooling on the workpiece. By adopting the quenching process provided by the invention, the medium carbon alloy steel with good wearing resistance can be obtained.
Description
Technical field
The invention belongs to the alloy prior processing technology field, be specifically related to a kind of quenching technology of medium carbon alloy steel.
Background technology
Metal wear resistant material is the metallic substance of consumption maximum in industrial production.Steel alloy is the sector applications such as cement, mine, electric power, chemical industry the most a kind of metal wear resistant materials.For example, 1～August in 2011, cement output was 13.2 hundred million tons, thermal power plant is 1,000,000,000 tons with coal, cement and thermal power plant all must pulverize through high-abrasive material with coal, in addition, all kinds of mines such as iron, copper, gold, aluminium, nickel all must first be carried out ore fragmentation and pulverized and select fine ore again, and the high-abrasive material consumption of raw ore per ton all is about one kilogram of left and right, very surprising! And, in the application of high-abrasive material, steel alloy accounts for the overwhelming majority.
Mankind's limited resources have on earth not only been wasted in a large amount of consumption of metallic substance greatly, and seriously affect and industrially normally carry out, and increase cost, increase maintenance, reduce operation rate, increase labour intensity, waste of manpower, material resources.Along with the development of suitability for industrialized production, equipment maximizes increasingly, more and more urgent to the requirement of high-abrasive material.Therefore, create the hope that novel high-abrasive material is whole world material scientific worker.
The development of abrasion resistance material mainly contains two aspects: the one, and the research and development of new composition, plastics on new materials, this is a very long and difficult process; The 2nd, the research and development of new production process, this refers under the prerequisite of similar Chemical Composition, by different smeltings and thermal treatment process, and obtains better wear resisting property.The key of the quality of high-abrasive material quality is thermal treatment process, and excellent thermal treatment process is to reduce to consume, and raises the efficiency save energy, the most effectual way of the limited resources of preserving our planet.The thermal treatment process of prior art can not make medium carbon alloy steel obtain good wear-resisting effect.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of quenching technology of medium carbon alloy steel is provided, apply the medium carbon alloy steel that this technique obtains and possess good wear resistance.
