Slag-What is it Good for? - USGS
But some recent research here at USGS might change slag’s poor public image. It turns out that, although slag is most known for being what’s left when metals have been removed, slag itself might be good at removing some negative chemicals from the environment.
Chloride corrosion of carbon steel pipe - Engineering …
I am specifying pipes for a water system with 500 ppm chloride in solution. Ordinarily we would specify 316L stainless steel to limit the corrosion, but I was asked if we could instead specify carbon steel pipe with a corrosion allowance. So instead of the typical
WHAT IS STEEL MAKING PROCESS: BRIEFLY EXPLAIN - …
What Is Steel making process? Steel making is the method of processing and producing steel from iron ore and scrap. It focuses on removing the slugs and other unwanted materials like phosphorus, sulphur, silicon, nitrogen, and excess carbon from the raw iron.

Steel Cleanliness : Deviations during the CAS-OB process
The results indie that cooling with scrap after the calcium treatment worsen the steel cleanliness in terms of non-metallic inclusions and should therefore be avoided. Furthermore, multiple of small aluminum additions late in the process is likely a contributing parameter to increase the projected length of the inclusions.

Deoxidation of steel [SubsTech]
2012/5/31· Solubility of oxygen in molten steel is 0.23% at 3090 F (1700 C). However it decreases during cooling down and then drops sharply in Solidifiion reaching 0.003% in solid steel. Oxygen liberated from the solid solution oxidizes the steel components (C, Fe, alloying elements) forming gas pores (blowholes) and non-metallic inclusions entrapped within the ingot structure.

In acidic soils, however, appliion of soluble calcium salt, such as calcium nitrate, can be helpful in avoiding aluminum and manganese toxicity. Figure 4.14 shows the positive effect of nutrigation with calcium nitrate on soil pH at the end of the irrigation season, on the surface soil, where it exerted its effect on the soil lattice.
