Highly Wear-Resistant Alloy Steel Forgings

Kev npaj ntawm kev hnav-resistant alloy steel forgings tshwj xeeb suav nrog cov kauj ruam hauv qab no:
(1) Nqus smelting: hnyav hlau ntshiab, aluminium blocks, ferromanganese, ferrochromium, ferrotitanium, ferrosilicon, ferromolybdenum, vanadium hais, npib tsib xee daim hlau, graphite electrode blocks, thiab ferroboron raws li cov khoom xyaw tsim, thiab tau txais cov hlau tom qab nqus tsev vacuum. ib qho ingot, sov lub demolded hlau ingot mus rau 850-950 degree thiab ua kom sov rau 0 5-1 teev. Tom qab lub tshav kub preservation tiav, cov hlau ingot yog forged rau hauv ib tug cam khwb cia ingot thiab ces txias rau chav tsev kub.
(2) Forging kev kho mob: kub lub ingot mus rau 1000-1200 degree ntawm 50-100 degree / h thiab khaws cia rau 05-2h, ​​ces txias rau {{5} }} degree ntawm qhov ceev ntawm 5-10 degree /s thiab khaws cia rau 10-30 feeb. Forging, forging yog muab faib ua ob kis ntawm deformation, lub sij hawm ncua ntawm ob kis yog 0.5 ~ 1.5h, thiab tus deformation tus nqi yog 0.5 ~ 1 / s; Tom qab kub forging tiav, quenching kev kho mob yog ua, thiab tus nqi txias yog 5 ~ 10 degree / s.
(3) Kev kho cua sov tom qab: ua kom sov lub phaj hauv ob sab phlu mus rau 600-700 degree ntawm tus nqi ntawm 50-100 degree / h thiab ua kom sov rau ntau tshaj 1 teev, tom qab ntawd kub rau {{5} } degree ntawm tus nqi ntawm 40-60 degree / h thiab ua kom sov rau ntau tshaj 2 teev, thiab tom qab ntawd txias rau 310-360 degree ntawm tus nqi ntawm 5-10 degree /s thiab ua kom sov rau ntau tshaj 2 teev. Tom qab cov cua sov preservation tiav, txias rau chav tsev kub.
Los ntawm cov qauv tsim, kub forging deformation thiab tom qab kev kho cua sov txheej txheem ntawm siab hnav-resistant alloy steel forgings, ib tug loj tus naj npawb ntawm dispersed multi-scale C hais thiab me me Beima complex theem qauv, loj-loj micron hais yog tsim nyob rau hauv lub alloyed nruab nrab. carbon steel qauv. Class C hais tuaj yeem tiv thaiv micro-txiav cov nyhuv ntawm abrasive hais. Cov me me sub-micron C hais thiab cov qauv zoo Beima tuaj yeem txhim kho lub zog ntawm cov matrix, yog li kev txhim kho cov matrix lub peev xwm los tiv thaiv deformation thiab ntxiv dag zog rau kev txhawb nqa rau loj-loj C hais. muaj nuj nqi, ho txhim kho qhov hnav tsis kam ntawm cov khoom.
