| Abstract Scope |
Insufficient or deviating cooling conditions in the water curtain of the secondary cooling zone are common causes for bleed-outs, especially during cast start with the risk of water-melt explosions. They typically rely on the flow conditions in the sump, the stress-strain conditions in the solidifying shell and insufficient water supply for cooling.
Hydro’s “water tester” is a robust tool to check the water flow rate and distribution in the water curtain of all types of casting molds. It is well accepted by operators due to its easy and ergonomic use.
The thermopile-array based “bleed-our detector” represents an even more detailed analysis tool of the cooling features of the used molds. It is a cost-efficient tool visualizing the water and temperature distribution in the secondary cooling zone suitable to trigger alarms or even automatic cast aborts.
This paper describes the technological approach and application cases for both tools. |
