Lub hauv paus ntsiab lus ntawm cua sov stainless hlau cua sov kav hauv cov khoom siv

Stainless hlau cua sov kav yog ua los ntawm high-temperature resistant stainless hlau seamless kav uas tusyees faib high-temperature hluav taws xob rauv nyob rau hauv cov kav dej. Cov qhov khoob yog ntom ntom ntom ntom nrog crystalline magnesium oxide hmoov nrog zoo thermal conductivity thiab rwb thaiv tsev. Cov qauv no tsis yog tsuas yog qib siab, siab hauv thermal efficiency, tab sis kuj ua kom muaj cua sov zoo ib yam. Thaum muaj tam sim no dhau los ntawm qhov kub-kub tsis kam xaim, cov cua sov tsim tawm los ntawm crystalline magnesium oxide hmoov mus rau saum npoo ntawm cov yeeb nkab hlau, thiab tom qab ntawd hloov mus rau qhov cua sov los yog cua, kom ua tiav lub hom phiaj ntawm cua sov.

Hluav taws xob cua sov hluav taws xob hluav taws xob cov khoom lag luam cov lus piav qhia

Lub hauv paus tseem ceeb ntawm cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob yog tsim los ntawm U-puab axial txheej txheem tiv thaiv cov xov hlau thiab ceramic txhawb thav ntawv welded ntawm qhov kawg. Tsis muaj kev tiv thaiv ntawm lub hauv paus tseem ceeb thiab lub tes tsho tiv thaiv sab nraud, thiab cov cua sov dissipation yog qhov zoo. Hauv cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob uas muaj qhov ntsuas kub ua haujlwm ntawm 1000 degrees, cov khoom siv ntawm cov hlau tsis kam yog Cr20Ni80 lossis 0Cr21Al6Nb, thiab qhov chaw ua haujlwm kub tuaj yeem ncav cuag 1200 degrees. Qhov siab tshaj plaws ua haujlwm kub ntawm hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob siv cov khoom siv no tuaj yeem ncav cuag 1000 degrees, thiab cov qauv kev txhawb nqa yog cov khoom siv aluminium siab. Lub tes tsho tiv thaiv sab nrauv yog lub tsho txias-dhau seamless nyias-walled kub-resistant steel yeeb nkab, ua los ntawm 1Cr25Ni20Si2 los yog 1Cr25Ni35Si2. Cov khoom siv muaj qhov kub thiab txias oxidation tsis kam, siab kub creep zog, thiab qee yam kev ua haujlwm los tiv thaiv carburizing. Kev tsim thiab xaiv cov khoom siv ntawm lub raj hluav taws xob no muaj kev nyab xeeb siab.

Cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob nrog qhov ntsuas kub ua haujlwm ntawm 1200 degrees Celsius yog ua los ntawm 0Cr27Al7Mo2 tsis kam xaim, thiab qhov chaw ua haujlwm kub tuaj yeem ncav cuag 1400 degrees Celsius. Qhov siab tshaj plaws lub sij hawm ua hauj lwm kub ntawm lub hluav taws xob cua sov hluav taws xob raj siv cov khoom no yog 1250 degrees Celsius, thiab cov kev txhawb nqa ncej yog ua los ntawm steel jade porcelain. Lub tes tsho tiv thaiv sab nrauv yog lub tsho txias-kos seamless nyias-walled kub-resistant steel yeeb nkab ua los ntawm Fe Ni Cr Al Re alloy. Cov khoom no muaj ultra-siab oxidation tsis kam thiab tuaj yeem ua haujlwm ntev ntawm 1300 degrees Celsius hauv qhov chaw oxidizing, thaum lub sij hawm luv oxidation kuj yog 1360 degrees Celsius. Haum rau kev ua haujlwm kub, tsis tshua muaj pa oxygen ib nrab siab, thiab ib puag ncig uas muaj S thiab C.

Lub tshuab hluav taws xob hluav taws xob hluav taws xob hluav taws xob tsim thiab tsim los ntawm peb lub Hoobkas tsis tsuas yog ua cov cuab yeej txhawb nqa rau ntau yam khoom siv kho cua sov hauv tsev, tab sis kuj tuaj yeem siv los tshawb nrhiav, tsim, thiab tsim cov khoom siv hluav taws xob tsis zoo rau cov neeg siv khoom. Raws li qhov xwm txheej siv, lawv tuaj yeem muab faib ua: cov cua sov-resistant steel seamless raj, phaj vaj huam sib luag welded raj, centrifugal cam khwb cia raj, thiab lub tes tsho tsis yog xim hlau.

Cov yam ntxwv ntawm high-temperature hluav taws xob cua sov hluav taws xob raj:

1. Kev tsim cov seamless txias drawn tshav kub-resistant steel kav uas tsim los ntawm cov khoom zoo raw khoom (nrog rau qhov kub siab tshaj ntawm 1200 degrees Celsius);

2. Cov tub ntxhais sab hauv txais yuav cov hlau U-shaped axial kev npaj thiab kawg vuam txoj kev;

3. Cov hlau tsis kam thiab cov thav duab ceramic yog qhov tsis muaj kev tiv thaiv, thiab qhov kub sib txawv ntawm cov hlau tsis kam thiab lub cub tawg yog me me;

4. Qhov siab tshaj plaws ua haujlwm kub yog 1000 degrees lossis 1200 degrees;

5. Qhov zoo tshaj plaws ntawm cov raj xa hluav taws xob uas tsim los ntawm peb lub tuam txhab yog kev siv seamless txias drawn, nyias-walled heat-resistant steel kav (1Cr25Ni20Si2 lossis 0Cr25Ni20Si2), uas muaj 10% siab dua thermal tawg dua cov khoom zoo sib xws;

6. Siv ntau tshaj 8000 teev.
