Tremendous liquid-solid shear heat, which was generated between the barrel groove and the screw channel in grooved melting zone, guaranteed that the material was melted
Take temperature readings at 5- or 10-minute intervals until ice is completely melted
and water has reached room temperature.
However, PHO does not exhibit spherulitic texture, so in order to determine crystallization rate all samples were melted
, then allowed to crystallize at different temperatures for 24 hours.
This phenomenon mixes melted
and unmelted plastic, reducing melt quality.
In the final analysis, total energy cost per ton of iron melted
is $23.42 for the cupola and $29.58 for the medium frequency electric furnace.
THE PRESSURE'S OFF Thick sheets of melted
rocks line the bottom of many large meteor craters.
* the foundry operator must determine if shortening the sinter counteracts the amount that can be melted
on a lining.
When climate warmed during interglacials, the North American and European ice sheets melted
, sending sea levels back up to a height on par with today's.
They must be melted
at 250 F so they can be dispensed through a gun like thermoplastic hot melts.
Robison also touched on metal loss when the metal is melted
but not poured in a casting.
Sand has twice the heat content of iron, thus every pound of sand in the charge equals 2 lb of iron not melted
. Another way to look at this is that for every pound of sand that goes into the furnace, two times the amount of energy is required to bring that sand up to the same temperature as the metal.
The result is a distributive mixing and melting process in which heat energy transfers from melted
to unmelted polymer.
