Comparison of the Hazardous Waste Slag Corrosion Resistance of SioxX-Zero and Cement-Bonded Al2O3–Cr2O3 Castables

Al2O3–Cr2O3 castables are one of the important refractories for hazardous waste incinerators. In this work, the hazardous waste slag corrosion resistance of Calcium Aluminate Cement (CAC) and SioxXZero bonded Al2O3–Cr2O3...

Microstructural and Microscopic Investigations of MgO–C Bricks – Relationships between Gas Permeability and Apparent Porosity or Pore Size by Controlling Relative Density

Changes in pore morphology from measurements of gas permeability, apparent porosity and pore size distribution of MgO–C bricks with controlled relative density were investigated. When the apparent porosity of the...

H2-Change: Refractories under Attack of Challenging Atmospheres during Transformation Process

Common and advanced lining materials for gas driven DRI shaft furnaces are discussed. Based on reformed natural gas as a standard a closer look is taken to the transformation route...

Study on Failure and Refining Effect of Purging Plugs with Different Slits

Due to severe service conditions, the life span of purging plugs is shorter than the lining of ladles, which results in lower production efficiency. To investigate the stress distribution, the...

MAGNA: From the Mine to the Steel Mill for 75 Years

MAGNA is one of the world’s leading companies as a vertically integrated producer of magnesium oxide (MgO) based solutions and materials for the steel industry, agriculture and environmental sectors. The...

A New Circular Economy: ReStoRe – Refractory and Steel Recovery by Deref

Deref S.p.A., an Italian company based in Genoa, is one of the main actors in the European markets of refractory recycling and products for the steel industry (i.e. metallurgical additives...

Investigation of the Tendency for Failure of Refractory Castables in the Wear Lining of a Steel Ladle Using Elongated or Cubic Shaped Tabular Alumina

Over the past decades, numerical simulation has proved to be a decisive tool for engineers. In the field of refractory technologies, numerical modelling helps increasing the understanding of the behaviour...

Dring Behaviour and Explosion Resistance of No-Cement Refractory Castables

For cement bonded refractory castables explosive spalling due to removal of free water and/or dehydration of cement hydrate have always been challenging. Naturally, cement free castables are very interesting due...

Impact of Melt Phase Formation on the High-Temperature Behaviour of MgO–CMA–C Refractories

Due to their excellent thermomechanical properties and corrosion resistance against aggressive steel/slag systems, carbon-bonded magnesia (MgO–C), alumina-magnesia (AMC), and magnesia-alumina (MAC) bricks are the dominating refractories for the lining of...

Post-Mortem Investigation of a Steel Ladle Repair Mix Containing Porous Calcium Magnesium Aluminate Aggregates

Monolithic ladle linings are cost efficient and environmentally friendly because a significant part of the used ladle lining can remain inside the ladle for a long time while only the...
