The Direct Pouring of Liquid Metal from the Reduction

The process had reached a state of development 'wherein the castings were made by pouring batches of about 135 pounds of liquid metal directly from the bomb into a water-cooled steel mold in the presence of air at atmospheric pressure. The pouring operation was effected through a mechanically operated valve in the bottom of the bomb.

Experimental Study of a Loop Heat Pipe with Direct

2021-7-30  A pouring silicate wick was manufactured to explore the influence of process and physical properties on the production and performance of loop heat pipes (LHP). This paper theoretically analyzed the advantages of pouring porous wick and introduced the technology of pouring silicate directly on evaporator. Based on this, the heat transfer performance of copper-methanol LHP system with pouring ...

Continuous Casting Process - an overview ScienceDirect ...

The continuous casting process is shown in Figure 1.9.1.Steel is poured from the ladle into the tundish, which provides a constant head for molten steel to flow from the tundish into the mold via a submerged entry nozzle (SEN).The copper mold is water-cooled and the bottom of the mold is initially sealed by a dummy bar of steel. When steel is poured from the tundish to the mold, it freezes to ...

In its simplest form, the process involves pouring liquid steel between two large counter-rotating water-cooled rolls. As the rolls rotate, the liquid steel begins to solidify a thin shell against the cold rolls, and at the “kissing point” of the two rolls, the two solid shells are pressed together and exit the bottom of
