SKT 4
SKT4 steel muaj zoo toughness, lub zog thiab siab hnav tsis kam. Nws cov khoom siv kho tshuab yuav luag zoo ib yam ntawm chav tsev kub thiab 500 ~ 600 degree. Thaum rhuab mus rau 500 degree, nws tseem tuaj yeem tuav lub hardness ntawm HB300.
Cov yam ntxwv thiab Scope ntawm daim ntawv thov
Txuj: (JIS 4404)
Vim cov hlau muaj molybdenum, nws tsis rhiab rau temper brittleness. Tom qab maj mam txias los ntawm 600 degree, qhov cuam tshuam toughness txo qis me ntsis.
SKT4 steel muaj zoo hardenability. Tom qab cov roj quenching ntawm 820 degree thiab tempering ntawm 560 degree, lub hardness ntawm txhua feem ntawm tus ntoo khaub lig-section ntawm ib tug 300mm × 400mm × 300mm loj daim hlau yog yuav luag tib yam.
Cov hlau no yog siv los ua ntau yam loj thiab nruab nrab forging tuag.
Cov hlau no yog ib qho yooj yim los tsim cov pob dawb thiab yuav tsum muaj kev tswj xyuas nruj ntawm cov txheej txheem smelting thiab cov cua txias tom qab forging thiab dov.
Lub ntsiab Technical Parameters

Quenching kub degree: 830-860
Kev xa khoom: Annealed HB Tsawg dua lossis sib npaug rau 241
Coolant: Roj
Mechanical Properties
tawv
Annealed, 241-197HB, indentation txoj kab uas hla 3.9-4.3mm
Kev kho cua sov specifications thiab metallographic qauv:
Kev kho cua sov specifications: quenching, roj txias ntawm 830 ~ 860 degree .
Delivery condition: Steel yog xa nyob rau hauv lub annealed mob.
Lub Hom Phiaj
SKT4 lost wax investment casting is suitable for manufacturing various large and medium-sized hammer forging dies and trimming dies with complex shapes, large impact loads, not-too-high working temperatures, and side lengths >400 hli. Nws yog siv los tsim cov duab yooj yim. Cov txheej txheem tsim khoom siv dav siv lub tshuab nqus tsev ua kom huv kom ntseeg tau tias cov hlau yog ntshiab; Kev kho cua sov loj tshaj plaws yog siv los ua kom tau qhov zoo tshaj plaws pre-hardening nyhuv ntawm cov hlau thiab cov hardness yog sib npaug.

Nco tseg:
1. Lub quenching cua sov kub ntawm pwm loj txais cov nqi txwv sab saud, thiab cov pwm me me (sab ntev hauv qab 200 ~ 300mm) txais yuav tus nqi qis dua;
2. Txhawm rau kom tsis txhob muaj kev ntxhov siab loj thiab hnyav thaum lub sij hawm quenching ntawm rauj forging tuag, tom qab cua sov los ntawm 830 mus rau 860 degree, nws yog thawj pre-txias hauv huab cua mus rau 750 rau 780 degree, thiab ces roj txias rau Ci ntawm 150 txog 180 degrees, tshem tawm thiab Temper tam sim ntawd;
3. cov pwm loj, yuav tsum tau preheated rau hauv lub qhov cub cua sov ntawm 600 mus rau 650 degree, thiab tom qab ntawd lub qhov cub kub yuav raug tsa tom qab cua sov. Txhawm rau kom sov tau zoo dua, cov pwm yuav tsum tau muab tso rau ntawm lub phaj rov qab nrog qhov siab ntawm 60 mus rau 100mm rau cua sov.
