低温硬化造型法是由英国W.H.Booth＆ Co, Ltd.& C.Moore(BOC)公司发明的新造型法。用水做粘结剂,使水冷冻,制成强度较好的铸型。这种铸型具有与壳型、干型匹敌的硬度。造型装置的费用也非常便宜。一般铸型,无论是湿型,还是用水玻璃系或有机粘结剂的铸型,在浇注铁水时,粘结剂都发生化学变化。而冷冻造型法的铸型,浇注后不发烟,且铸型的溃散性非常好,旧砂再生也很容易,被认为是造型工艺中的一次革命。 Low temperature hardening modeling method is the United Kingdom W. H. Booth & Co, Ltd. & C. Moore (BOC) company invented a new modeling method. Water as a binder, the water frozen, made of better strength mold. This type of mold has a shell-type, dry-type match the hardness. Modeling device costs are also very cheap. The general mold, whether it is wet type, or water glass or organic binder casting, pouring molten iron, the binder chemical changes have taken place. The frozen modeling method of casting, pouring smoke, and the collapse of the mold is very good, the old sand regeneration is also very easy, is considered a revolution in the modeling process.
