the continuous improvement of eaf performance is crucial for the increase in productivity and cost effectiveness and to render an environmental friendly process. rhi supports these targets by providing a diverse range of refractory and process solutions. chemical energy in practical operation by injection of gaseous media like oxygen and natural gas, and solid materials like carbon have become ...

Bottom-up approach is a potentially useful tool for hydrogel assembly of cell-laden individual building blocks. In this article, we assembled individual building blocks of photocrosslinkable microgels in a rapid and controlled manner. Individual building blocks of poly(ethylene glycol) (PEG) microgels with square and hexagonal shapes were fabricated by using a photolithography technique. Indivi...

This paper presents a microfluidic mixer that uses acoustic stirring created by ultrasonic waves. The ultrasound is introduced into the channel by integrated piezoelectric transducers. The transducers are made of a zinc oxide thin film, which is deposited on the bottom surface of a quartz substrate. The poly(dimethylsiloxane) channel is aligned to the transducers on the top surface of the subst...

The first part of the project is mainly about changing of slag compositions and see it affect on the inclusions in the ladle furnace. The second part of the project is to study the influence of stirring (EMGAS) on the large inclusions in the steel by changing stirring conditions. The project has done at Uddeholm AB, Hagfors. First, the scrap is melted in ARC furnace then moved to the ladle de-s...

_I BHARMACIA GRADIENT MIXER GM-1 The prime requirement for the production of linear ionic strength gradients is efficient mixing of the components of the gradient. In the Pharmacia Gradient Mixer GM-1 this is achieved by a blade configuration which lifts the dense incoming solution from the bottom of the mixing chamber and distributes i t evenly throughout the whole eluant at a low stirring spe...
