摘要：

The　effects　of　the　category　and　content　of　cored　materials　on　FFR　(fume　formation　rate)　were　studied.The　results　show　that　cored　materials　can　be　divided　into　three　kinds　in　which.　the　first　one　can　enhance　the　FFR,　the　second　one　can　lower　the　FFR,　and　the　third　one　has　no　effects　on　the　FFR.　Different　kinds　of　cored　materials　and　its　content　have　different　effects　on　the　FFR.　FFR　is　enhanced　to　couple　with　the　increasing　of　the　contents　of　Na2SiF6.　No　obvious　effects　of　the　ilmenite　on　the　FFR　can　be　found.　The　FFR　can　be　lowered　greatly　when　the　core　perfect　matches　of　metal　powders　and　feldspar.　It　is　propitious　for　lowering　the　FFR　when　increasing　the　content　of　feldspar　in　appropriate　confine　ment.
