Abstract
The present invention relates to casting medium manganese steel which belongs to ferrousalloy. The present invention has the ingredients (by weight) of 0.6 to 0.8% of C, less than 0.5% of Si, 8 to 10% of Mn, 0.2 to 0.4% of Mo, 0.2 to 0.4% of V, 0.4 to 0.6% of Cu, 2 to 3% of Cr, at most 0.04% of S, at most 0.04% of P and Fe as the rest; the ingredients (by weight)selected priorly are 0.7% of C, less than 0.5% of Si, 9% of Mn, 0.3% of Mo, 0.3% of V, 0.4% of Cu, 3% of Cr and Fe as the rest. The material has the advantages of superior abrasion resistance, good welding property, simple smelting technology and heat treatment technology, and is suitable for manufacturing blades for mixing and stirring mud on brickmaking stirrers.
Description
The invention belongs to ferrous alloy, be applicable to that the mud of making on the brickmaking stirrer that closes stirs cutter.
Closing mud and stir cutter and claim to stir leaf again, is the consumable accessory on the brickmaking stirrer.At present, most of brickmaking factory, especially township and village enterprises's brick field still adopts A
3Carbon Steel Plates such as steel are made, and just do not heat-treat and use, so serious wear, steel quantity consumption is big.The only a few brick field adopts Fe-05 powder agglomates or wolfram steel powder built-up welding surface of steel plate, and also high and complex process fails to popularize because of cost.Though the high mangaenese steel wear resistance is good, cost is low, and its weldability is poor, thermal treatment process complexity and not seen widespread use.
The objective of the invention is to make a kind of casting manganese steel of weldable wearproof, it is good both to have had the high mangaenese steel wear resistance concurrently, cheap, is convenient to advantages such as casting, and it is simple to have thermal treatment process again, the characteristics that weldability is good.
Alloy provided by the invention has (by weight) 0.6～0.8%C,＜0.5%Si8～10%Mn, and 0.2～0.4%Mo, 0.2～0.4%V, 0.4～0.6%Cu, 2～3%Cr ,≤0.04%S ,≤0.04%P, all the other are Fe.The composition of preferentially selecting for use is (by weight) 0.7%C,＜0.5%Si, 9%Mn, 0.3%Mo, 0.3%V, 0.4%Cu, 3%Cr.All the other are Fe.
This weldable wearproof Medium Manganese Steel is than the A that uses at present
3The relative wear resistance of steel has improved 6～10 times, and material cost only improves 0.6 times.Close the work-ing life that mud stirs cutter thereby improved, saved great deal of steel.This steel is applicable to the melting of industrial production atmosphere, can add the part steel scrap, and sufficient raw is cheap.And be convenient to the returns melting.The foundry goods of casting after the melting directly is thrown into " water is quick-fried " in the water when taking out from sandbox under 900～1100 ℃ of high temperature, carry out quench treatment.Cast(ing) surface light after the processing does not have sand and oxide skin, does not have heat treatment crack yet.Just this foundry goods and carbon element rod iron can be welded together with common welding rod (as tying 422 welding rods) common process, not have weld crack, satisfy service requirements.
Embodiment:
The present invention is starting material with common ferromanganese, molybdenum-iron, high carbon ferro-chrome, vanadium iron and pure iron (or carbon steel scrap stock), and alloying constituent is (by weight), 0.7%C, and＜0.5%Si, 9%Mn, 0.3%Mo, 0.3%V, 0.4%Cu, 3%Cr, all the other are Fe and impurity element.By this prescription melting in induction furnace, then in the sand mo(u)ld top casting.Foundry goods takes out from sandbox under 900～1100 ℃ of high temperature and directly is thrown into " water is quick-fried " in the water, carries out quench treatment.Foundry goods after the processing just can weld use with the carbon element rod iron with the common welding rod common process.
