METHOD AND DEVICE FOR PREPARING MOLD WALL FOR CASTING OR FORMING TO FOLLOWING CASTING CYCLE, ATOMIZED ELEMENT WITH CENTRIFUGAL SEPARATION AND AIR CONTROL AND USING METHOD FOR ATOMIZING TREATMENT FOR ATOMIZING MOLD WALL TREATING AGENT WITHOUT SUBSTANTIALLY CONTAINING SOLVENT

摘要

PROBLEM TO BE SOLVED: To improve the suitability to the environment so as not to develop the trouble to the waste liquid treatment in a method and a device for preparing a mold wall for casting or forming a cast product in order to make provision for the following cast cycle after completing the cast cycle. SOLUTION: The supply of heat to the mold walls 12a, 12b or the removal of heat from these walls and the coating of mold wall treating agent onto the mold walls 12a, 12b, are executed in this order with a controlling method, in which these operations are mutually independently executed, i.e., there is not the overlap in the time among these operations, desirably a program controlling method. That is, after firstly raising the temp. of the mold walls 12a, 12b, particularly the surfaces thereof to a prescribed temp., these are coated with the mold wall coating agent. Then, as a coolant, water is used and since Leidenfrost effect is scarsely developed, the treating agent can do to use by only little quantity and the good suitability to the environment is obtd. and the cost is reduced.
