摘要:
A transport device, in particular, for transporting cooling blocks (5) in a casting machine with caterpillar mold, wherein the transport device includes: a plurality of roller elements (4), which circulate endless in a caterpillar-like manner on a circulating path U and is drivable by a drive device (33); at least two parallel guide paths (20), each of which includes one or more roller running surfaces (12a, 12b) and each of which extends over the entire circulating path U; wherein each roller element (4) includes a roller element body (34), which has a first end (35) and a second end (36) in the direction of circulation; each roller element (4) includes at least one roller (10) respectively in the area of the first end (35) and in the area of the second end (36); and the rollers (10) situated in the area of the first end (35) of roller element body (34) roll on roller running surfaces (12a, 12b) different from those of the rollers (10) situated in the area of the second end (36) of the roller element body (34).

摘要:
A method for cooling casting caterpillar mold blocks provides for a coolant spray case that has a rarefied atmosphere to prevent the escape of coolant. The apparatus to carry out the method has a casing, spray nozzles and connecting pipes and is connected to a source of rarefied pressure.

In a mold apparatus for an endless track type continuous casting machine of the type in which a plurality of cooling blocks are interconnected with each other in the form of an endless chain to assemble a cooling block chain which can define a straight wall; a pair of said cooling block chains are disposed such that the straight wall thereof define a mold; and the cooling block chains are moved in synchronism with the casting speed or rate, a plurality of cooling holes are extended through each cooling block in the direction perpendicular to the direction of the movement thereof and in parallel with the straight wall section thereof; one or more cooling water pipes are disposed along one side surface of said straight wall section of each cooling block chain and are provided with a plurality of nozzles in line with the cooling holes of the cooling blocks so that the cooling water is injected through the nozzles to their corresponding cooling holes of the cooling blocks which are moving, thereby cooling the cooling blocks in contact with a casting with the cooling water. Therefore, the cooling blocks can be cooled very effectively; a satisfactory shell growth rate can be attained; and break-out or the like can be avoided even when the cooling block chains are stopped in case of emergency.
摘要:
A method and device for cooling molds circulating in a horizontal plane, in which siphon action is used to pass cooling liquid from a top gutter through the molds. In this way the whole cooling system is becoming constructively simplified, such that production speeds can be increased, with the consequent greater length of the cooling system, but without its becoming unduly complicated. This effect is realized irrespective of the nature of the machine or the number of molds.Method and device are especially advantageous when applied with the manufacture of plastics tube, more particularly yet with the manufacture of plastic corrugated tube.
