Abstract
A self-curing mixture for preparing foundry cores and moulds comprises a filler, an aqueous sodium silicate binder, a sulphate or sulphonate foaming agent, and a highly basic metallurgical slag with CaO:SiO2 ratio from 1.5:1 to 3.0:1. The foaming agent may be a sodium alkylbenzenesulphonate, alkylnaphthalenesulphonate alkyl sulphonate, or alkyl sulphate in an amount 0.05-0.2% by wt. of the mixture. The slag may be a self-disintegrating ferrochromium slag in an amount 2.0-7.0% by wt. of the mixture. The filler, which is about 93 to about 98% of the mix, may be quartz sand, olivine sand or chromomagnesitic powder. Optional additives include 0.5-2.0% anhydrous calcium sulphate as accelerator, 0.01-0.1% alkali metal borate or phosphate, e.g. borax, as retarder, 0.01-0.2% sodium soap, e.g. sodium naphthenate as foam stabilizer, 1-5% kerosene as foam destabilizer and/or graphite, coal, coke, pitch, sawdust or alumina to improve "knock-out" properties of the set substance. The mixture is mixed with 1.0-5.5% water and set in a core-box.
