Foundry coke em i wanpela bikpela samting insait long metal kasting indastri, na i save givim gutpela hat na kemikel ridaksen envairomen long proses bilong meltim. I no olsem 'metalurgical coke', 'foundry coke' i nidim bikpela 'post-reaction strength (CSR > 60%), liklik 'reactivity' (CRI < 30%), na i gat gutpela 'combustion characteristics'. Hai-kwaliti faunderi kok i save gat asis aninit long 10-12%, salfa aninit long 0.7%, na ol samting i save pairap klostu long 1.5%, na dispela i mekim na i gat gutpela melting tempereja na hai-puriti ain i melt.
Moden 'foundry coke' prodaksen i save yusim ol 'high-quality low-volatile coals (olsem 'coking coal' na 'fat coal') long stretpela mak na i save stretim 'coke structure' long rot bilong ol spesel wok bilong 'coking', olsem 'dry quenching' (CDQ). Ol bikpela samting bilong bodi em: strong bilong bruk (M40) > 85%, strong bilong bruk (M10) < 8%, na 'porosity' i stap namel long 35-45%. Ol dispela samting i save senisim 'cupola furnace permeability', 'melting efficiency', na 'molten iron quality'.
Intanesenel Faundri Asosiesen (IFA) i makim faundri kok i go long tripela gret: premium gret bilong hai-end presis kasting, Gret 1 bilong ol otomotiv pat kasting, na Gret 2 bilong jenerel kasting prodaksen. Sapos yu makim stretpela gret, dispela inap long mekim 'melting efficiency' i go antap long 15-20 pesen na daunim olgeta eneji we yu yusim long 8-12 pesen. Wantaim ol lo bilong lukautim envairomen we i wok long gro, askim bilong 'low-emission foundry coke (liklik salfa na liklik 'nitrogen') i wok long go antap hariap, na i soim wanpela groa reit bilong 18% long wanwan yia.
