Abstract

PURPOSE:To cast a hollow billet of small fluctuations in inside diameter by installing a refractory core concentrically on the inner side of a water cooled mold, and controlling the temp. of the core so as to be kept constant during casting. CONSTITUTION:A core to be installed concentrically on the inner side of a water cooled mold is made into a circular truncated cone shape having a circular columnar upper part B and a tapered lower part A. The angle theta of the taper is preferably about 5-30 deg.. The set value of the ouside wall temp. of the core is stored in a temp. detection controller 26 and is compared with the actually measured value of a temp. detection end 25. If the actually measured value is higher than the permissible upper limit value of the set value, the output signal of the controller 26 is put into a flow rate controlling valve 27 for coolant to increase the flow rate of the coolant to be supplied into the inlet 23 of a coolant flow pipe 22. Conversely, when the actually measured value is lower than the permissible lower limit of the set value, it is so controlled as to decrease the flow rate of the coolant.
