1. Alternative form of deadmelt
   • 1913, William Henry Fowler, The Mechanical Engineer - Volume 31, page 646:

     It has to be run eight hours after reaching 1,600°, as high oxygen contents of the bath are not permissible in an acid furnace, and for quite one to two hours an endeavour is made to dead melt, that is, deoxidise the steel.

   • 1929, Blast Furnace and Steel Plant - Volume 17, page 275:

     As crucible steel is dead melted and killed to a point where it is absolutely quiet, the holding period is just another factor in emulating the crucible practice to produce quality steel.

   • 1969, Metal Producing - Volume 7, page 75:

     An arc furnace dead melts and desulphurizes the stainless steel charges.

Noun

dead melt (plural dead melts)

1. Alternative form of deadmelt
   • 1911, Proceedings of the Engineers' Society of Western Pennsylvania:

     This would give it a "dead melt" and improve the quality considerably at a very small cost.

   • 1951, The Australasian Engineer, page 46:

     However, the short heat time of the dead melt process partially offsets this disadvantage, and it is generally conceded that such a heat will not contain as much gas as a well oxidized heat which is then held for a prolonged period at a high temperature of superheat under reducing conditions.

   • 1966, John D. Sharp, Elements of steelmaking practice, page 117:

     In the manufacture of acid steels the advisability of a dead melt has already been stressed, and the bath should be free from any signs of bubbling if it has been achieved.
