Ua ib qho khoom siv tseem ceeb thiab txo tus neeg sawv cev hauv lub chaw kev lag luam, kev faib tawm ntawm cov khoom siv ua kom pom tseeb tsuas yog nyob ntawm cov ntaub ntawv raw, siv thiab kev ua haujlwm zoo. Raws li cov kev lag luam thoob ntiaj teb muaj cov kev tiv thaiv ib puag ncig thiab ua haujlwm, cov hom pom ntawm Coke yog qhov ua kom haum rau cov txheej txheem sib txawv.
Raws li cov khoom ntawm raw cov ntaub ntawv, foundry coke tuaj yeem muab faib ua ob pawg: cov khoom siv thee raws li cov coke feke Feke Feke. Coal-raws li Foundry Coke siv siab coking thee raws li cov khoom siv tseem ceeb thiab yog ua los ntawm qhov siab qhuav distillation. Nws muaj cov yam ntxwv ntawm lub zog siab, cov hmoov tshauv qis cov ntsiab lus thiab zoo reactivity, thiab yog siv dav hauv kev tsim cov hlau loj. Roj roj coke Feke Feke yog ua tiav los ntawm roj av coke, cov khoom lag luam ntawm cov roj av rov ua dua tshiab. Nws muaj cov ntsiab lus sulfur tsawg thiab yog qhov tsim nyog dua rau cov txheej txheem casting nrog cov kev tiv thaiv nruj ib puag ncig.
Los ntawm qhov kev pom ntawm kev siv, Foundry Coke tuaj yeem muab faib ua ke ua kom zoo nkauj coke thiab siab-ua haujlwm foundry coke. Cov Khoom Taw Qhia Zoo tib yam yog siv hauv cov txheej txheem tsoos, xws li kev tsim cov xim txho cam khwb cia hlau chaw. Nws yog tus cwj pwm los ntawm cov nqi qis thiab ruaj khov. High-Performance Foundry Coke yog tsom ntawm cov kev xav tau ntawm precision casting los yog high-end castings. Nws muaj cov nqi qis dua calorific thiab ntau ruaj khov tshuaj lom neeg, uas tuaj yeem txo cov cam khwb cia thiab txhim kho cov txiaj ntsig tau.
According to physical properties, foundry coke can also be divided into large coke, medium coke and powder coke. Loj coke (particle loj dua lossis sib npaug rau 80mm) yog tsim nyog rau cov hluav taws kub loj lossis lub sijhawm kub, uas muaj zog kub thiab ruaj khov siv hluav taws xob; nruab nrab coke (particle loj 40-80mm) yog hloov pauv hloov mus rau cov khoom me me thiab nruab nrab. Hmoov Coke (Particle Loj<40mm) is often used as auxiliary fuel or in casting coatings to improve heat transfer efficiency.
Nyob rau hauv xyoo tsis ntev los no, nrog kev zawm ntawm cov kev tiv thaiv kev tiv thaiv ib puag ncig, qis-sulfur thiab low-volatile foundry Coke tau dhau los ua cov kev ua lag luam. Qee cov khoom lag luam siab kawg kuj ntxiv cov kab cim qib thev naus laus zis los ua kom zoo dua lawv cov kev ua kom zoo thiab ib puag ncig. Cov kev faib tawm ntau yam kev faib tawm tsis yog tsuas yog xaiv cov peev txheej ntawm cov lag luam hauv ntiaj teb, pab kom txo cov nqi, nce kev ua tau zoo thiab ua tiav kev txhim kho kom ruaj khov.
