Kev kho deg ntawm precision steel yeeb nkab yog los ntawm kev hloov cov precision steel nto cov ntaub so ntswg kho cua sov kom hloov ib qho chaw nto.

Deg hardening kaum ib deg qauv hloov, tsis hloov cov tshuaj muaj pes tsawg leeg ntawm qhov chaw kho cua sov. Nws tuaj yeem siv high-frequency, intermediate zaus los yog zaus tam sim no induction cua sov los yog nplaim hluav taws kub txoj kev. Lawv qhov tshwj xeeb yog sim precision steel nto yog rhuab mus rau lub quenching kub, thiab thaum tshav kub kub tseem tsis tau kis mus rau qhov chaw ntawm lub plawv chav tsev, ces txias sai heev, thiaj li hais tias siab hardness, toughness thiab lub plawv Ministry tseem siab.

Kev hloov pauv hauv kev kho cua sov kho tshuaj kho kaum ib precision steel nto tshuaj lom neeg muaj pes tsawg leeg thiab lub koom haum tshwm sim. Kev kho tshuaj nyob rau hauv raws li precision steel raj nkag mus rau saum npoo ntawm cov khoom sib txawv tuaj yeem muab faib ua carburizing, nitriding, carbonitriding, alloying thiab lwm yam. Txhim kho thiab txhim kho nws cov precision steel hnav tsis kam, corrosion kuj, qaug zog kuj zoo heev. Txog tam sim no txoj kev loj hlob sai ntawm kev kho tshuaj, kev siv ntau yam tshiab.

Hauv kev tsim kho tshuab, ntau lub tshuab qhov chaw, xws li crankshaft ntawm lub tshuab hluav taws xob sab hauv, lub zog, lub tog raj kheej thiab lub iav reducer yog qhov tseem ceeb, tsis yog tsuas yog yuav tsum tau cov tub ntxhais seem muaj qhov toughness txaus, ductility thiab flexural zog, thiab yuav tsum muaj qee qhov tuab. ntawm sab hauv ntawm lub siab hardness, siab hnav tsis kam thiab siab qaug zog. Cov kev kho cua sov uas tau hais los saum toj no yog qhov nyuaj rau kev ua tiav ib txhij ua tiav cov kev xav tau saum toj no, thaum siv cov kev kho cua sov saum npoo yog txoj hauv kev zoo tshaj plaws kom ua tiav cov kev ua tau zoo no.
