Patent DE-19625405-A1 (DE)
Title: Cooling arrangement and process for e.g. molten materials or slags
Inventor: KOLEV NIKOLAY IVANOV DR ING
IPC: G21C9/016
Filed: 1996-06-25
Abstract: An arrangement for cooling a heated solid or liquid material, especially a melt, slag, or the like, using an externally stored cooling medium includes a chamber (2) for the heated material, and a coolant reservoir (4) connected to at least one pipe with an outlet opening (6) for the coolant. A closure device (8), which prevents the flow of coolant before the cooling process begins, includes a response chamber (11) in which the coolant outlet opening (6) is located. The response chamber (11) is filled with a liquid medium and is closed on either side with bursting elements (13,14). A sensor which senses the temperature of the material directly or indirectly, is operatively connected to the closure device (8) and causes the closure device to open when a predetermined temperature is reached. The sensor element (9) consists of at least one hollow body (15) in the vicinity of the material to be cooled which is filled with a medium suitable for the transmission of pressure. The sensor  is connected to the response chamber via the first bursting element (13), and when the critical temperature of the sensor element (9) is reached, the first bursting element (13) reacts (by rupturing) under the pressure of the sensor medium. A shock wave is released in the medium inside the response chamber (11), as a result of which the second bursting element (14) ruptures and releases the flow of coolant out of the coolant outlet (6) into the container (2) for the heated material. Also claimed is a process for cooling a hot solid or liquid material (particularly a molten material, slag, or the like).
