Lub siab hardenability ntawm RQ65 alloy structural steel daim hlau qhia ntau yam -dimensional technical zoo nyob rau hauv alloy structural daim ntaub ntawv, thiab nws cov nqi tseem ceeb nyob rau hauv lub meej adaptation rau complex ua hauj lwm tej yam kev mob thiab cov khoom tseem ceeb. Cov nram qab no systematic tsom xam los ntawm cov yam ntxwv kev mus rau lub tswv yim kev siv qhia tau hais tias tus nqi tshwj xeeb coj los ntawm nws siab hardenability:

I. Qhov tseem ceeb thiab kev ua tau zoo ntawm Hardenability

Lub hardenability ntawm RQ65 stems los ntawm kev sib koom tes tsim ntawm nws alloy muaj pes tsawg leeg:

 

Kev sib xyaw ntawm cov khoom siv alloy: Chromium (0.4-0.7%) thiab molybdenum (0.2-0.3%) ua kom nthuav dav ntawm martensite ntau yam los ntawm ncua kev hloov pauv pearlite; npib tsib xee (0.7-1.0%) txhim kho qhov kub thiab txias thaum txhim kho austenite stability; vanadium (0.04-0.12%) refines nplej thiab inhibits overheating nyiam.

Quantitative kev ua tau zoo ntawm hardenability: Txheeb xyuas los ntawm Jominy kawg -quench test, nws cov hardenability nkhaus npog ntau yam, kom ntseeg tau tias steel phaj nrog ib ntu tuab ntawm tsawg dua los yog sib npaug rau 100mm tseem tuaj yeem tau txais cov qauv martensite zoo nyob rau hauv cov roj txias, thiab cov tub ntxhais hardness fluctuation tsawg dua los yog sib npaug li 5HRC.

II. Core Application Advantages Tsav los ntawm High Hardenability

1. Kev lees paub ntawm kev ua tau zoo sib xws rau cov khoom loj thiab cov khoom sib txawv

Uniform hardening ntawm cov ntu loj: In scenarios such as heavy machinery gears (modulus ≥20) and high-pressure vessel heads (thickness >80mm), lub siab hardenability ntawm RQ65 xyuas kom meej tias qhov sib txawv hardness ntawm cov tub ntxhais thiab qhov saum npoo yog tsawg dua los yog sib npaug rau 3HRC, thiab lub zog tensile hloov pauv yog tswj tsis pub dhau ± 5%. Piv txwv li, tom qab lub mining machinery kis ncej (inch 300mm) tau txais RQ65, nws lub neej qaug zog nce los ntawm 40%, thiab qhov kev pheej hmoo tsis ua hauj lwm tau txo los ntawm 60%.

Adaptability rau cov duab complex: Cov qauv xws li qhov sib sib zog nqus (aperture Tsawg dua lossis sib npaug ntawm φ50mm) thiab cov phab ntsa nyias (thickness Ntau dua lossis sib npaug li 8 hli) tsis muaj qhov muag muag hauv zos tom qab quenching. Piv txwv li, tom qab quenching, lub puab phab ntsa hardness ntawm ib tug siv machinery hydraulic lub tog raj kheej chim (phab ntsa thickness 25mm) mus txog 48-52HRC, ua tau raws li cov hnav tsis kam yuav tsum nyob rau hauv high-pressure (35MPa) ua hauj lwm tej yam kev mob.

2. Kev Txhim Kho Kev Txhim Kho Hauv Kev Ua Haujlwm Zoo heev

Optimization ntawm qis-kub toughness: Qhov sib ntxiv ntawm npib tsib xee ua rau RQ65 kom muaj kev cuam tshuam lub zog ntau dua lossis sib npaug ntawm 28J ntawm -40 degree, deb tshaj li ntawm 25CrMo4 (kev cuam tshuam lub zog Ntau dua lossis sib npaug ntawm 35J ntawm -20 degree). Nws yog qhov tsim nyog rau kev siv lub tshuab hluav taws xob hauv nruab nrab ntawm lub tshuab chassis (xws li cov khau bulldozer taug qab), thiab nws cov pob txha tawg tsis kam ntawm -30℃yog txhim kho los ntawm 30%.

Txhim kho qhov siab -kub stability: Thaum ua hauj lwm ntawm 560℃ntev, nws lub zog thermal (ntev -lub sij hawm lub zog Ntau dua los yog sib npaug rau 180MPa) zoo dua li cov tsoos Cr-Mo steel. Nws tau raug siv nyob rau hauv superheater headers ntawm thermal power stations (ua hauj lwm kub 540 degree), thiab lub neej kev pab cuam yog ncua mus rau ntau tshaj 100,000 teev.
