Cov nyhuv ntawm Tempering Sijhawm rau Hardness

 

Short - sij hawm Tempering (xws li 1 - 2 teev): Yog tias lub sijhawm tempering luv luv, lub martensite decomposition tsis tiav, thiab nag lossis daus ntawm carbides yog me me thiab qhov sib sau ua ke tsawg. Nyob rau lub sijhawm no, qhov txo qis hauv hardness ntawm shipbuilding steel phaj yog me me. Piv txwv li, tom qab tempering rau 1 teev, qhov hardness tsuas yog txo los ntawm 5 - 10 HRC units. Rau qee qhov xwm txheej uas nws cia siab tias yuav tswj tau qhov nyuaj thaum txhim kho lwm yam khoom (xws li toughness), luv luv-lub sij hawm tempering yog ib qho kev xaiv.

 

Lub sijhawm Tempering ntev (xws li 2 - 3 teev): Raws li lub sijhawm tempering txuas ntxiv mus rau 2 - 3 teev, lub martensite yog tag nrho decomposed, thiab ntau cov carbides yog precipitated thiab aggregated. Qhov no yuav ua rau kom tsis tu ncua ntawm lub hardness ntawm lub nkoj tsim steel phaj. Piv txwv li, tom qab tempering rau 3 teev, qhov hardness yuav txo tau los ntawm 15 - 20 HRC units piv nrog lub xeev quenched, ua rau cov hlau softer thiab ntau haum rau cov txheej txheem shipbuilding uas yuav tsum tau zoo machinability.

Kev sib raug zoo nrog lwm yam khoom thiab kev siv hauv nkoj tsim

 

Correlation ntawm Hardness thiab Toughness: Qhov txo qis hauv hardness thaum lub sij hawm tempering txheej txheem feem ntau yog nrog los ntawm kev nce hauv toughness. Thaum lub sij hawm voyage ntawm lub nkoj, lub nkoj tsim steel phaj yuav tsum muaj tej yam toughness los tiv thaiv dynamic loads xws li yoj cuam tshuam thiab kev sib tsoo. Los ntawm kev tswj xyuas qhov kub thiab lub sijhawm ntawm tempering kev kho mob kom txo tau hardness thiab txhim kho toughness, shipbuilding steel phaj tuaj yeem hloov kho kom zoo dua rau cov kev xav tau ntawm kev tsim khoom thiab siv. Piv txwv li, rau lub nkoj sab thiab lwm qhov chaw uas yooj yim cuam tshuam los ntawm kev cuam tshuam, lub nkoj tsim steel phaj nrog txo hardness thiab txhim kho toughness tom qab tempering kho tau zoo tiv thaiv nkig puas.

 

Correlation ntawm Hardness thiab Machinability: Tom qab lub hardness txo, lub machinability ntawm lub nkoj tsim steel phaj yog txhim kho. Hauv kev tsim cov nkoj, ntau yam kev ua haujlwm xws li txiav, vuam, thiab khoov yuav tsum tau nqa tawm ntawm lub nkoj tsim steel phaj. Lub zog qis ua rau cov haujlwm no yooj yim dua rau kev ua tiav thiab tuaj yeem txo qhov muaj peev xwm ntawm cov kab nrib pleb thiab lwm yam tsis xws luag thaum lub sijhawm machining txheej txheem. Piv txwv li, thaum welding lub nkoj tsim steel phaj, qhov qis hardness tuaj yeem txo qhov hardness ntawm tshav kub - cuam tshuam thaj tsam ntawm vuam thiab txo cov tiam ntawm vuam tawg, txhim kho vuam zoo.
