    摘要： A kneaded sand property adjusting system including: a kneading device; a kneaded sand storage hopper that stores kneaded sand; a molding device that molds the sand conveyed from the sand storage hopper; a control device that controls water injection until a property of the sand meets a kneaded sand target property; and kneaded sand amount measuring instruments that measure the amount of sand stored in storage hopper, wherein the control device stores the batch number of each kneaded batch and the kneaded sand property measured at the time of kneading, calculates the batch number of the kneaded batch that corresponds to the molding sand being loaded into the molding device by the kneaded sand amount measuring instruments, associates the property of the molding sand with the property stored on by the batch number that was calculated, and corrects the target property on the basis of the values of the properties.

    摘要： A method for managing a casting process based on measured properties of molding sand is provided so that casting defects or energy used can be reduced by changing the molding conditions for the mold to be produced or changing the steps after molding. The method for managing a casting process based on the properties of the molding sand comprises a step (1) of measuring the properties of the molding sand just before the molding sand is supplied to a molding machine (40) and a step (2) of determining if the measured properties of the molding sand comply with predetermined properties, wherein, if by the step of determining it is found that the measured properties do not comply with the predetermined properties, a mold is molded to have less strength than that of a mold that is molded by using molding sand whose properties do comply with the predetermined properties.

    摘要： A method for managing a casting process based on measured properties of molding sand is provided so that casting defects or energy used can be reduced by changing the molding conditions for the mold to be produced or changing the steps after molding. The method for managing a casting process based on the properties of the molding sand includes a step (1) of measuring the properties of the molding sand just before the molding sand is supplied to a molding machine (40) and a step (2) of determining if the measured properties of the molding sand comply with predetermined properties so as to then switch between a step of molding a mold when the measured properties do comply with the predetermined properties and a step of molding a mold when the measured properties do not comply with the predetermined properties.

    摘要： A process and an apparatus for cooling and handling sand in which hot used sand is delivered to a mixer and mixed with cooler sand. The mixed sand is discharged from the mixer for circulation on conveyor means for further cooling and the cooled sand is separated into a first fraction for discharge to successive milling and moulding stages and a second fraction for return to the mixer to effect sand mixing with the hot used sand. Water may be added to the mixed sand in the mixer to adjust the moisture content and to increase cooling.
