Xyuam xim rau kev siv lub cub tawg hluav taws xob
Txhawm rau tiv thaiv thiab txuas lub neej ntawm lub tshuab ua kom sov, cov ntaub ntawv hauv qab no yuav tsum raug sau tseg:
(1) Txheeb xyuas tsis tu ncua tias txoj kev sib txuas ntawm lub cub hluav taws xob thiab lub maub los yog qhov zoo.
(2) Cov qhov cub hluav taws xob thiab cov tswj hluav taws xob yuav tsum tau ua haujlwm ntawm qhov ntsuas cua ntawm qhov ntsuas tsis pub tshaj 85%, tsis pub muaj plua plav paug, cov pa tawg thiab cov roj uas tuaj yeem ua rau cov hlau tsis zoo thiab cov khoom siv hluav taws xob.
(3) Kev ua haujlwm ib puag ncig ntsuas kub ntawm lub maub los (raws li qhia sab xis) yog tsawg rau 0-50 ° C.
(4) Thaum siv hluav taws xob rauv taws thiab cov tswj hluav taws xob, lub zog ntsuas hluav taws xob yuav tsum tsis pub tshaj lub hwj chim rated. Lub tso cua sov yuav tsum tsis pub tshaj qhov ntsuas kub siab tshaj plaws. Nws yog txwv tsis pub muab cov haujlwm ntub dej tso rau hauv qhov cub ua kom sov. Lub tso tawm ua haujlwm muaj ultra-high noo noo yuav tsum ua ntej kom qhuav.
(5) Khaws lub cub tawg sab hauv kom huv, tshem cov hlau oxides, slag thiab impurities hauv lub cub tawg kom ncav sijhawm, thiab ceev faj thaum thau khoom thiab thau tawm ntawm cov haujlwm.
