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 castables were comparatively investigated. The results showed that the slag corrosion and penetration resistance were related to the adopted slags (SiO2-rich, CaO-rich slag, and Fe2O3-rich) … Weiterlesen …

Evaluation of Test Methods for Refractory Bricks: A Comparison and Validity Study of some Cold Crushing Strength Standards

Following Part 1 of this publication series which dealt with the procedure and the determination of precision of Cold Crushing Strength (CCS) data on several refractory brick grades, part 2 deals with the comparison of ISO 10059-1/EN 993-5 and ASTM C133. This includes the influence of specimen shape (50 mm cylinders and 50 mm cubes) … Weiterlesen …

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 MgO–C bricks with increased relative density was decreased, the gas permeability was also decreased. In addition, with decreasing average pore size, MgO–C bricks decreased their … Weiterlesen …

Three Decades of Alphabond 300: An Overview of its Technical Advantages

Alphabond 300 has been used in many applications since it was developed three decades ago. In this paper an overview is presented of the different technical advantages for applications where Alphabond 300 is used. Alphabond 300 is a calcia-free hydratable alumina based on pure alumina. In castables containing components such as silica and magnesia, the … Weiterlesen …

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 via hydrogen boosted coke oven gas in an integrated steel plant up to the pure hydrogen use in a pilot plant, especially by using different … Weiterlesen …

Development of Microsilica-Gel Bonded Castable for Nose Ring Application

Refractory castables with improved thermomechanical properties are necessary in the nose ring areas of cement production rotary kilns to withstand thermal cycling and clinker particle abrasion. However, commonly used low- and ultra-low cement castables have limited thermal shock and abrasion resistance due to lime presence in the binders. This study investigates the potential of a … Weiterlesen …

Trimet: Sophisticated Alloys with a High Level of Recycled Material

Next to energy-efficient drive systems, lightweight construction materials are a key technology in the transport sector when it comes to reducing the environmental impact through increased resource efficiency. Various aspects of sustainability in mobility and the minimizing of CO2 emissions during the entire product life cycle are of particular interest in the automotive industry. An increasing focus in this respect is the outlay during production of components where up to 95 % of emissions can be saved through the use of recycled aluminium when compared to primary material use. Consequently, the demand in the industry for aluminium alloys with a high level of recycled material has increased sharply. High-strength wrought and cast secondary aluminium alloys can make an important contribution to climate targets. Trimet Aluminium SE/DE is involved in a number of research projects endeavoring to make materials of this kind with a positive life cycle assessment available.
