The Dephosphorization Steelmaking Furnace* of Hot . - CiteSeerX

Synopsis. The preliminary dephosphorization method of hot metal outside the steelmaking furnace was investigated to obtain extra low phosphorus steels and to utilize the LD slag. Hot metal with the phosphorus content of 0.09- 0.16 % was treated in a ladle with the dephosphorization agent consisting of LD slag and iron.

Austempered Ductile Iron (ADI) - MDPI

Jan 12, 2018 . 320 ◦C, 340 ◦C and 360 ◦C. Tensile strength, yield strength, percentage elongation and impact energy were evaluated for the as-cast and austempered samples. Microstructures were investigated using microscopy, coupled with analyzing software and a scanning electron microscopy. The specific wear.

Occurrence and behaviour of Mo containing precipitates in nodular .

The behaviour of Mo precipitates in the as cast state as well as under long exposure to heat was the object of this investigation. In the as cast state, Mo forms metastable carbidic grain boundary precipitates with iron, silicon and carbon. These transform into stable MoC precipitates during sustained temperature influence.

A study of sulphur effect in high silicon ductile irons: International .

Late sulphur additions to post-inoculated high silicon ductile irons were studied by means of microstructural characterisation and thermal analysis, complemented with statistical tools, image analysis and thermodynamic modeling. Using a 4.31% carbon equivalent iron melt, two low sulphur levels were investigated in an.
