ESTIMATION OF BASIC OPEN HEARTH SLAG COMPOSITION BY ITS REFLFCTING MICROSCOPIC STRUCTURE

The Estimation of Slag Properties

The Phase Composition of Electric Furnace Slag

Elementary and phase composition as well as micrography of the electric furnace slag were examined. The base of slag is made from phases containing Fe, Mn and Ca. Grains differ in size and shape, they cling together to form bigger or smaller agglomerates, depending on separated fractions. Relative distribution of identified phases in separated fractions is presented and the possibility of phase...

Study on Phosphorus Microscopic Enrichment Regularity of Earlier and Final Slag in Double –slag Steelmaking

C. X. Li, H. Li, H. Lu, W. W. Mao: State key laboratory of advanced Metallurgy, University of Science and Technology Beijing, China This work examined phosphorus enrichment in different micro areas of the earlier slag and the final slag in converter double-slag technology. The results show that: phosphorus has high enrichment in the micro-area the basictity of which is between 2 to 2,5; the pho...

Role of Surface Phenomena on Converter Slag Composition

For beneficiation of converter slag, the role of surface phenomena on slag composition was studied. This work includes some experimental data, which were measured for basic oxygen steel (BOS) slag in Isfahan Steel Plant. All data were collected on site in the plant. The results support the idea that surface activity plays a major role in converter slag formation. It was also a new finding t...

Open clamp structure in the clamp-loading complex visualized by electron microscopic image analysis.

Ring-shaped sliding clamps and clamp loader ATPases are essential factors for rapid and accurate DNA replication. The clamp ring is opened and resealed at the primer-template junctions by the ATP-fueled clamp loader function. The processivity of the DNA polymerase is conferred by its attachment to the clamp loaded onto the DNA. In eukarya and archaea, the replication factor C (RFC) and the prol...
