On-Site Generated Hydrogen May Offer Lower Costs and Green Benefits for Annealing
Large-scale annealing uses large quantities of hydrogen often produced via steam methane reforming of natural gas. Steam methane reforming releases large volumes of carbon dioxide, and is a relatively complex plant to operate, requiring dedicated staff. In some cases, annealing plants may be served with delivered liquid hydrogen, which is derived from remote hydrogen sources, then liquefied and transported to customers sites via trailer truck. Liquid hydrogen simplifies the hydrogen supply infrastructure compared to steam-methane reforming but is a more expensive source of hydrogen. Electrolysis-generated hydrogen has been used worldwide for hydrogen supply for decades but has generally been a niche production approach because of high electricity costs. Now the grid pricing impact of renewable energy is making electrolysis hydrogen generation an increasingly attractive option for large scale hydrogen supply. Compared to SMR and liquid hydrogen options, electrolysis-generated hydrogen offers important advantages – carbon-dioxide-free hydrogen generation, simpler and more flexible operation than SMR, lower staffing and maintenance requirements compared to SMR, a smaller footprint compared to either SMR or a hydrogen gas farm, lower cost and Green Hydrogen if renewable energy is available in excess in the local area. Attendees for this presentation will take away the following: Options available in electrolysis hydrogen to serve a variety of hydrogen delivery ranges, Typical costs of supply for electrolysis hydrogen, Forces in the marketplace that are electrolysis a more competitive approach to hydrogen generation. What is new about this presentation is that continued process enhancement and cost reduction in water electrolysis technology, combined with dynamic electrical pricing driven by the impact of renewable electricity production have made water electrolysis newly competitive as a large-scale hydrogen supply approach.

Magnetic Structurescopy (Coercimetry) for Quality Assessment in Metallurgy and Metalwork Manufacturing
Magnetic structurescopy (Coercimetry) basis is correlation between physicochemical properties or mechanical characteristics of metal and one or more magnetic characteristics. Structural changes in the metal caused by heat treatment or deformation are followed by changes of magnetic characteristics. A number of steels and cast iron have unambiguous correlation between coercive force and inspecting properties with wide range of coercive force value change. This correlation enables use of a non-destructive method to measure the magnetic characteristic, the coercive force efficient, precise and practical for assessment of high-temperature thermomechanical treatment of rolled steel or finished items, sorting of steel grades, assessment of mechanical properties of rolled steel, annealing quality inspection, quality conformance inspection for quenching and subsequent tempering, check the depth and hardness of the hardened layers on the surface, evaluation of fatigue and residual life of metal and many others.

Bonded Abrasive Technology: Reducing Labor Costs by Adding Comfort
For metal fabricators, the cost of grinding abrasives normally represents only a small portion of the total cost of a project yet cutting down on consumable costs often seems attractive in order to keep spending low. The reality is much different: fabrication shops will only see real savings by reducing their labor costs. Most of the improvements and trends in bonded abrasive technology have been to reduce labor time by improving productivity, safety and added comfort for operators. For a grinding disc to save fabricators real dollars, it must strike a balance between these three key trends. Discover how Walter Surface Technologies has helped strike this balance on the shop floor in order to save fabricators time and money, and help operators work more efficiently and safely.
