Description
Technical field
Using method when the present invention relates to a kind of drying unit and corresponding chill and being used to cast.
Background technology
Chill is meant to increase the local cooling velocity of foundry goods, the metal Quench thing of laying in sand mold, core surface or die cavity.Foundry goods is because the needs of its structure, various piece wall unevenness often, thicker position is just cooled off slowly in the process of cooling, the position of wall thickness is just cooled off soon, this just makes each position cooling velocity inequality of same foundry goods, can cause the position of the wall thickness of foundry goods to produce shrinkage cavity or the drawing crack phenomenon appears in the thin position of wall.For fear of the generation of this phenomenon, during moulding, place chill at the position of wall thickness, absorb the temperature of molten iron with chill, quicken the cooling velocity at this position, shorten and time difference of the position cooling of other wall thickness.
Chill is cast enterprise and is extensive use of.Because the surface of chill is adsorption moisture easily, in molten steel pouring course, can make the surface of foundry goods produce pore, especially iron casting, the pore of cast(ing) surface is more obvious, in addition, sand mold and the core of forming casting mold also contain certain moisture, so most Foundry Works all toasts the casting mold die cavity that is placed with chill, thereby sand mold, core and chill is dried after moulding finishes.But this processing mode still can cause near the part of chill that is positioned at of foundry goods to produce pore, thereby influences the quality of foundry goods.
