Isitena sodongwe esisezantsi esinemingxuma eli-19

Izitena zodongwe zineempawu zokuchasana okuphezulu, amandla alungileyo, uzinzo oluhle lokutshatyalaliswa kwe-thermal, kunye nokuchasana nokupholisa ngokukhawuleza kunye nokufudumeza. Ukongezelela, izitena ezinqambileyo zodongwe zinokuxhathisa ukukhukuliseka kwe-acidic slag ukuya kwinqanaba elithile. Ngokumalunga nokusetyenziswa, izitena ezinqanda udongwe zincinci, zinemveliso enkulu, kwaye zisetyenziswa ngokubanzi.
