The porosity defects in the ingot, which are caused by moisture absorption slag during electroslag remelting process, deserve researcher’s attention summer wet season. prediction of weight gain is critical for developing baking and scheduling strategies can assist workshop managers making informed decisions industrial production electro remelting. under conditions different air humidity, experi...

The use of low frequency or DC (i.e., direct current) operation in the electroslag remelting process may lead to electrolysis some oxides slag pool, which will adversely affect cleanliness ingot. In order confirm this view, effect different power supply modes on oxygen content and inclusions ingot has been studied by adopting self-designed furnace as experimental equipment. pulse heating inert ...

High-strength steels are pre-heated in gas-fired furnaces before undergoing the open-die forging process. This process increases thermal oxidation on steel surfaces, affecting interfacial friction between ingot and anvils during deformation. Two medium carbon high-strength with different nickel contents were oxidized, mechanical characteristics of oxide layers investigated by micro nano-indenta...

A valuable characteristic of the "IPS Empress" used for producing all ceramic dental restorations is that it is a prefired ceramic ingot. The ingot is heated, softened and press-injected into the cavity, and ceramic restorations are fabricated by the lost wax casting method. The leucite crystal present in the ingot are scattered and distributed into the glassy phase in a more homogeneous manner...

The phase equilibria of the Al-Cu-Fe quasicrystalline phase (y phase) is complex and conventional crystal growth techniques like the Bridgman and Czochralski methods are not applicable in preparation of large crystals. Large single grains of the y phase been have prepared by either slow cooling or isothermal anneals. In the later technique, arc melted ingots were subjected to either single or m...

The continuous casting process of metals and alloys is nowadays frequently utilized in metallurgical industry, and more general in material engineering. Typically, the liquid material flows into the mould (crystallizer) having the walls cooled by flowing water. The solidifying ingot is pulled out by the withdrawal rolls. Below the mould the side surface of the ingot is very intensively cooled b...
