Boron Adsorption-Desorption by Steelmaking Slag for

2020-7-17  Steelmaking slag, a by-product of the steel-refining process, could be used for removing boron excess from irrigation natural and waste waters, due to its strongly alkaline reaction. The objectives of this study were to: (a) establish the optimum conditions (external solution/adsorbent ratio, equilibration time) of boron adsorption by the slag, (b) assess the slag’s capacity to adsorb boron ...

Development analysis of boron steel smelting technology

2013-2-25  Boron steel is a kind of steel use boron as the main alloying element, also known as the boron-treated steel. Just need to add a very small amount of boron in the steel can significantly improve the hardenability of steel, the effect was hundredfold of general metal powder such as manganese, chromium, nickel, so it can use trace boron instead of a large number of metal elements.

Boron in Steel: Part One :: Total Materia Article

Boron in Steel: Part One. Abstract: At the atmospheric pressure and temperature of 0°C boron is a solid material. Boron optimum quantity which has to be added in the steel to achieve maximum hardenability, based on experience is about 0.0003 to 0.0030% B. Boron is supplied to steelmakers as ferroboron or as one of several proprietary alloys.
