Abstract
The present invention relates to chemical constituents of metallic materials and a heat processing method thereof, which belongs to a creeper tread used by a tractor or a bulldozer. The metallographic structure of the creeper tread of the present invention is bainite or austenite. The present invention adopts low-alloy steel mainly containing chromium, manganese and silicon, and is quenched in a constant temperature, and then a heat processing technology that the low-alloy steel is cooled in the air is adopted; finally, the metallographic bainite structure or the metallographic austenite structure is obtained. The structure has reasonable combination of strength, toughness and hardness. Thus, service life is prolonged.
Description
The invention belongs to tractor, dozer grip-pad, relate to the chemical ingredients and the heat treating method of metallic substance.
China produces the grip-pad material at present and mainly contains two kinds: one is to use high mangaenese steel (Mn13), and high mangaenese steel is that more than 100 year historical antifriction metal material arranged.Production technique is after cast form, carry out the tough processing of water, but intensity is lower.Under the working conditions of grip-pad, can not obtain sufficient work hardening, the potentiality of material are not fully played.Drag the 31Mn2Si low alloy steel grip-pad of company's development by one besides.After cast form, quenching adds tempering, obtains martensitic stucture.Be characterized in that alloy addition is few, cost is low, and intensity and tough performance satisfy the needs of grip-pad, but hardness is lower, and wear resistance and high mangaenese steel are close.
The objective of the invention is to reduce the grip-pad production cost, improve its work-ing life.
The objective of the invention is to be achieved by the following scheme.Select metallic substance C0.32～0.42% of suitable chemical ingredients for use, Cr0.8～2.0%, Mn1.0～2.0%, Si0.8～2.0%, Ti0.06～0,1%, Re0.1～0.2%.And the thermal treatment process of isothermal quenching.Both after the cast form, grip-pad is heated to 860～920 ℃ after, under 260～350 ℃ temperature, be incubated 20～40 minutes.
Grip-pad of the present invention has adopted the heat-treatment technology method of isothermal quenching, can obtain bainite, austenite metallographic structure.This tissue has the good combination of rational strength, toughness, hardness, and its hardness, toughness are higher than 31Mn2Si, hardness, and intensity is higher than high mangaenese steel.So soleplate of low-alloy austenite-bainite steel has the advantage of high life, also possesses process stabilizing, processing ease, the characteristics that production cost is low simultaneously.
Embodiment:
Press C:0.32～0.42%, Cr0.8～2.0%, Mn:1.0～2.0%, Si:0.8～2.0%, Ti:0.06～0.1%, Re:0.1～0.2%.Chemical ingredients melt out molten steel and pour into grip-pad, Fig. 1 is a thermal treatment process synoptic diagram of the present invention, at first grip-pad is heated to 860～920 ℃, then in 2～3 seconds time, it is that 260～350 ℃ nitrate groove carries out isothermal quenching that grip-pad is put into temperature, the time of quenching is 20～40 minutes, cools off in air at last.So promptly can obtain bainite and～grip-pad of austenite metallographic structure.
The present invention is applicable to the grip-pad of producing various crawler tractors, dozer, excavator.
Claims (2)
1, a kind of tractor, dozer soleplate of low-alloy austenite-bainite steel, the chemical ingredients that it is characterized in that described grip-pad material is: C:0.32～0.42%, Cr0.8～2.0%, Mn:1.0～2.0%, Si:0.8～2.0%, Ti:0.06～0.1%, Re:0.1～0.2%, the metallographic structure of material is bainite and a spot of austenite, obtains by isothermal quenching.
2, the described tractor of claim 1, the dozer heat treating method of soleplate of low-alloy austenite-bainite steel, it is characterized in that grip-pad is heated to 860～920 ℃, be incubated after 20 minutes, the nitrate groove of putting into temperature and be 260～350 ℃ carries out isothermal quenching, and under this temperature, be incubated 40 minutes, in air, cool off at last.
