cold shut

[′kōld ‚shət]
(metallurgy)
A surface defect of a metal casting in the form of a discontinuity where two streams failed to unite. Also known as cold lap.
Freezing of the top surface of an ingot before the mold is full.

Attach the cold shut to the end of the chain with the lap link, bolt the chain to your post or gate, and put the eye screw on the opposite gate.
Potential problems in the production of thin-wall castings are misruns and cold shuts. The cores that form thin-wall sections on the casting should be avoided or redesigned to provide uniform fill of the entire mold cavity.
For example, if metal temperature in the mold is examined, a short time after filling (t=6.0 sec) the coldest spot is precisely where cold shuts in the partition were seen on the casting.
The cold shut defect was seen in SEM images that isolated the iron beads that had formed.
This cold shuts down the feeding responses offish or lessens their need to eat.
* Cold shuts can be used as temporary repair links.
For prediction of misruns, cold shuts and other filling-related defects we have a fast CFD solution module called FLOWCast[TM].
For prediction of misruns, cold shuts and other filling-related defects we have an optional fast CFD solution module called FLOWCast[TM].
* localized defects--including shrink porosity, cold shuts, hot tears, inclusions, foil, cracks and runout;
Under more severe pouring conditions, such as when using gating systems that produce turbulent flow and can cause cold shuts, lustrous carbon films can be flushed into the body of the casting or become sandwiched between two merging streams of molten metal (Fig.
Rapid cooling of thin wall sections of the casting reduce the fluidity of the molten metal, which could cause the molten metal to prematurely freeze before it can completely fill the mold cavity, resulting in an incomplete fill or cold shuts. The mold filling capability in thin wall casting depends on a number of different process and design related variables, including the type of metal, pouring temperature, casting shape and metalcasting process.
