Make the sand mould with sand wet water slightly higher than the wet sand. After system of sand mold, mold cavity surface to be coated with fireproof paint, then put in oven drying, to its type and pouring after cooling.
Dry clay sand mould Take a long time, a large amount of fuel is consumed, and the deformation in the drying process of sand mould, precision castings are affected. Clay dry sand mold commonly used in the manufacture of steel and cast iron pieces. After chemical hardening sand widely adopted, dry sand mold was eliminated.
Clay sand is sand casting industry according to the original a modelling with sand, silt content classification in the industry of clay sand quartz and the content of harmful impurities without specific request.
For silt content is less than or equal to 50%.
Clay sand is mainly used for cast iron and nonferrous metals casting with the addition of moulding sand and core sand, to improve the wet strength, improve the model performance.
