Abstract
本原料为一种铸造凝固增热材料，此增热材料为铝(或铝合金)(或镁粉)、硅钙粉、氧化增热剂、耐火造渣材料粉及金属氧化物粉(或矿石粉)，按适当比例加以混合，其中有铜、铁、镍或钴的氧化物粉分别用于铜及铜合金；合金钢、不锈钢、铁基高温合金；镍基合金及钴基金等的浇铸中，优点：应用范围广；铸造成品率高，缩孔及疏松等缺陷基本消除，能彻底解决液固相温差太近难浇铸合金的浇铸问题；不污染金属，不改变金属化学成分。
Description
本发明涉及一种延缓铸造凝固的增热材料。
目前在铸造行业中，使用传统的发热剂，如铸造手册中所列铝热剂，主要由粒度1－2mm的氧化铁粉和铝粉组成，另加二氧化硅，氧化铝粉，此种加热剂不足之处是应用范围窄，只能用于铁基合金；并且发热反应的主要成分粒度较粗，发热效率不高，只能在一定程度上减轻缩孔，对于难浇铸件成品率不高，而且所用氧化铁粉是用磨碎氧化铁皮的方法制成难，成本较高。
为解决以上铸造中所使用加热剂的不足，本发明的目的提供一种延缓金属熔液凝固，能广泛用于多种金属及合金的高效发热剂，主要采用细矿石粉末添加氧化增热剂提高反应发热效率，从而达到消除金属锭及铸件缩孔和疏松等缺陷，提高锭子及铸件成材率的目的。
本发明延缓金属熔液凝固高效加热剂所用原料为：
铝，铝合金，镁粉(任一种) 5－45％
硅钙粉 0－40％
氧化增热剂 0．5－20％
耐火造渣材料粉 5－30％
金属氧化物粉，矿石粉(任一种) 10－80％
其中金属氧化物粉(矿石粉)，粒度为 0．005－0．5mm。
其中金属氧化物粉末为铜、铁、镍或钴的氧化物粉末。
使用方法：金属锭及铸件浇铸完后，在金属熔液表面覆以5－30mm厚的一层该发热剂，在发热剂上再加一层耐火保温材料，效果更佳，用在发热冒口，发热铸模时，在冒口、铸模制作材料中混入30－85％的发热剂，并以水玻璃或其它粘结剂粘结即可。
本发明的优点：应用范围广泛；用此发热剂后铸造缩孔及疏松等缺陷基本消除，大大提高了成品率，能彻底解决一些液固相温差太近难浇铸合金的浇铸问题；不污染铸造金属，不改变铸造金属化学成份。
本发明的实施例：
取：铝粉 12％(粒度为0．5mm以下)
硅钙粉 15％
氯酸钾 2％
尖晶石、氧化钙、氧化铝粉 27％
氧化铁粉 44％(粒度为0．5mm以下)
由于采用氧化铁粉，可直接用于合金钢，不锈钢或铁基高温合金的铸造模成型中。
