Cov kev qhia tseem ceeb ntawm cov kab hlau dov npog ntau yam thiab tseem ceeb heev rau kev ntsuam xyuas kab kev ua tau zoo, cov khoom zoo, thiab kev tswj tus nqi. Cov hauv qab no yog qee qhov ntsuas tseem ceeb:
1. Qhov taw qhia tso zis
Qhov nruab nrab ib teev tso zis: Qhov ntsuas no qhia txog lub peev xwm ntawm lub tshuab dov thiab kev txawj ntse ntawm cov neeg ua haujlwm dov zeb. Nws hais txog qhov nruab nrab ntawm cov khoom tsim nyog uas tsim los ntawm ib teev los ntawm lub tshuab dov. Cov mis laij lej yog: Qhov Nruab Nrab Ib Teev Tso Tawm (tons / teev)=Tus naj npawb ntawm cov khoom tsim nyog tsim (tons) / Lub Sijhawm Ua Haujlwm (teev).
Calendar Operating Rate: Qhov ntsuas no qhia txog kev siv tus nqi ntawm cov khoom siv dov zeb hauv ib lub sijhawm. Nws hais txog qhov feem pua ntawm cov dov zeb lub sijhawm ua haujlwm tiag tiag raws li feem pua ntawm lub sijhawm ua haujlwm. Cov qauv kev suav yog: Calendar Operating Rate (%)=Lub Sijhawm Ua Haujlwm Tseeb (teev) / Calendar Lub Sijhawm (teev) × 100%.
2. Qhov Ntsuas Zoo
Steel Qualification Rate: Qhov ntsuas no qhia txog qhov zoo ntawm kev ua haujlwm thiab kev tswj xyuas thaum lub sijhawm tsim khoom. Nws hais txog qhov feem pua ntawm cov hlau tsim nyog uas tsim los ua ib feem pua ntawm tag nrho cov tshuaj ntsuam xyuas steel ntim. Cov mis laij lej yog: Steel Qualification Rate (%)=Tsim Nyog Kev Tshawb Fawb Steel Quantity (tons) / Tag Nrho Cov Hlau Tshawb Xyuas Ntau (tons) × 100%.
Yield Rate: Qhov taw qhia qhia txog kev siv cov khoom siv raw thiab kev ua haujlwm ntau lawm. Nyob ntawm cov txheej txheem tsim khoom, tus nqi tawm los tuaj yeem raug cais raws li tus nqi tawm los ntawm ingot mus rau billet, tus nqi tawm los ntawm billet rau billet, thiab tus nqi tawm los ntawm kub- dov rau txias- ua haujlwm. Cov qauv kev suav dav dav yog: Tus Nqi Tshaj Tawm (%)=Tsim nyog Steel Ntau Lawm (tons) / Raw Material Consumption (tons) × 100%.
Surface Quality: Qhov no suav nrog qhov ua tiav saum npoo, xim, muaj cov kab nrib pleb, suav nrog, thiab lwm yam tsis xws luag ntawm lub sawb.
Puab thiab Dimension Accuracy: Qhov no suav nrog cov ntsuas xws li thickness, dav, thiab phaj puab (xws li yas, wedge puab, ntug thinning, thiab ncaj). Cov ntsuas no muaj kev cuam tshuam loj rau kev ua haujlwm tom qab thiab kev ua haujlwm ntawm cov khoom.
Mechanical Properties: Cov no suav nrog lub zog tensile, elongation, thiab lwm yam khoom, qhia txog lub zog thiab plasticity ntawm cov hlau.
3. Lub zog thiab cov khoom siv ntsuas
Unit Energy Consumption of the Steel Rolling Process: Qhov no yog hais txog tus nqi ntawm cov qauv thee sib npaug (TCE) ntawm ntau yam roj thiab lub zog xav tau los tsim ib tuj ntawm cov hlau tsim nyog. Cov mis laij lej yog: Unit Energy Consumption of the Steel Rolling Process (TCE)=Total Plant Roj thiab Fais Fab Consumption - Khib Nyiab Heat Recovery (TCE) / Tsim Nyog Hlau Ntau Lawm (Tons).
Roller Consumption: Qhov no yog hais txog tus naj npawb ntawm cov menyuam yuav tsum tau tsim ib tuj ntawm cov hlau tsim nyog. Cov qauv kev suav yog: Cov Menyuam Siv (TCE)=Cov Menyuam Siv Khoom (TCE) / Tsim nyog Steel Ntau Lawm (Tons).
