Khawb hlauhais txog cov khib nyiab steel (xws li trimmings, xaus, thiab lwm yam) uas tsis dhau los ua cov khoom thaum lub sij hawm tsim cov hlau mills, nrog rau cov khoom siv hlau hauv cov khoom siv thiab cov khoom uas tau muab pov tseg tom qab siv. Cov hlau nplaum yog hlau, thiab cov hlau nplaum yog npua hlau. Lawv tau sau ua ke hu ua seem hlau.
Kev tshuaj xyuas txoj kev
I. Tshem tawm ntawm impurities
(1) Lub ntsuas qhov hnyav tau teeb tsa ntawm qhov chaw thauj khoom. Tom qab unloading, qhov hnyav yog kuaj nyob rau hauv kev saib xyuas ntawm tus neeg soj ntsuam zoo.
(2) Yog tias tsis ua raws li cov xwm txheej, cov impurities tseem tshuav thaum lub sijhawm thauj khoom tuaj yeem muab tso rau hauv lub thawv ruaj khov rau qhov hnyav thiab txiav tawm.
II. Kev soj ntsuam zoo
(1) Lub chaw raug kaw thiab cov chaw saib xyuas raug teeb tsa. Cov neeg muag khoom raug txwv nruj heev los ntawm kev nkag mus rau hauv qhov chaw thauj khoom kom tsis txhob cuam tshuam nrog kev ua haujlwm ntawm cov neeg soj ntsuam zoo.
(2) Cov neeg muab khoom yuav tsum tau yuav cov khoom raws li qeb, uas yog, hnyav, nruab nrab, me me, thiab cov khoom ntim khoom sib cais thiab yuav khoom sib cais. Qhov no tuaj yeem daws qhov teeb meem ntawm kev muab qhab nia tsis raug.
(3) Thaum thauj nws los ntawm lub tsheb ciav hlau, wagons hnyav tshaj 57 tons tsis tau muab qhab nia thiab tuaj yeem txiav txim siab ntawm ib tus nqi.
Nws crushing thiab ua technology Cov txheej txheem rau crushing loj-loj thiab tshwj xeeb-zoo li tus seem hlau uas tsis yooj yim rau nkag mus rau hauv lub cub tawg, thauj, thiab cais muaj xws li: roj txiav, poob rauj, blasting, shearing, shredder crushing, thiab lwm yam. Cov khoom siv sib txawv, tsis sib xws, thiab qhov sib txawv zoo hauv kev sib xyaw, nws nyeg cuam tshuam rau kev txhim kho cov hluav taws xob ua hluav taws xob. Yog li ntawd, nws cov pretreatment tuaj yeem txhim kho qhov kev ua tau zoo thiab kev tawm tswv yim ntawm cov khoom steel.
Lub cheeb tsam kev faib tawm ntawm kuv lub teb chaws cov khoom seem steel kuj tsis sib npaug. Ntau tshaj 80% ntawm cov peev txheej hauv lub tebchaws tau muab faib rau hauv 12 lub xeev thiab lub nroog nrog cov chaw lag luam thiab cov lag luam mining thiab cov neeg coob, suav nrog Beijing, Tianjin, Shanghai, Guangdong, Liaoning, Heilongjiang, Hebei, Shanxi, Shandong, Hubei, Sichuan thiab Jiangsu; Lwm thaj chaw muaj thaj chaw tsis zoo thiab cov neeg tsawg, thiab cov peev txheej tsim tawm tsawg dua 20%.
