Ceramic Industry's July 2013 New Product Highlights showcases five great products from these five great companies:
- Harper International - Thermal Processing Systems
- L&L Kiln Mfg. Inc. - Kilns
- Morgan Advanced Materials - Insulating Firebrick
- Unifrax LLC - Coating Material and Insulating Boards
- Union Process - Attritor
This company’s advanced thermal processing systems for high-purity ceramics are reportedly used by customers who required 99.99%+ purity goals and beyond. For example, Harper’s custom system (pictured) is designed for conversion of aluminum chloride. It includes a rotary furnace for removing volatiles (calcination) and a higher temperature vertical furnace for phase transformation.
The vertical furnace can minimize the opportunity for product sticking or gas-phase entrainment during processing and maximize product uniformity and reaction time by minimizing or eliminating bulk bed effects. It also reportedly provides better heat and mass exchange between products and reactants for improved efficiency and limits heating and cooling requirements to the process material only; containment remains at temperature and the process material moves through it. Harper’s furnaces are tailored to each customer’s processing needs. Visit www.harperintl.com.
L&L Kiln Manufacturing Inc.
Ergo-Lift kilns are designed to offer easy and ergonomic loading while providing the advantages of a top-loading kiln. The kilns can reportedly provide ease of maintenance, easier moving of the kiln, and protection from the hot case. Able to be loaded from all four sides, the kilns are based on L&L’s DaVinci square and rectangular kiln line. They include hard element holders, protected thermocouples, three elements per kiln section, and three-zone control.
Two inside heights are available (27 and 36 in. high) in a variety of square and rectangular crossections, and sizes up to 26.7 ft2. Visit www.hotkilns.com.
Morgan Advanced Materials
A full product range of insulating firebrick (IFB) is now available for the ceramic market, including kilns, furnace linings and cyclical furnaces. Manufactured by this company’s Thermal Ceramics business, 10 different grades are available to meet the temperature needs of all applications, from 2,300-3,300°F.
The K®-23 IFB is reportedly an industry staple, manufactured with a slurry casting process that produces low thermal conductivity and good thermal shock characteristics. Rated at 2,300°F, the flagship K-23 brick has low density, high hot strengths, good thermal stability, and ultra-low thermal conductivity. For high-temperature kiln linings, Morgan now offers Insalcor®, a high-temperature firebrick with a use limit of up to 3,250°F. Visit www.morganthermalceramics.com or call (706) 796-4200.
Fiberfrax® Silplate® Mass 1500, the latest addition to the Silplate product line, is a hot face coating material for use over ceramic fiber modules, castables and refractory brick. It is ready for application at temperatures up to 1,500°C/2,732°F and can be applied on ceramic fiber insulation to form a surface that is highly resistant to abrasion and flame impingement. Silplate Mass 1500 can also minimize heat loss, increase refractory life, and provide heat reflectance/energy efficiency and thermal shock protection.
Fiberfrax Silplate structural insulating boards are specially designed for backup applications that require a high-strength refractory insulating material. Common applications are for backup in ladles or tundishes that are used in molten metal transportation. Using Silplate boards for backup applications can reportedly significantly reduce steel shell cold face temperatures. Visit www.unifrax.com or call (716) 278-3800.
A dry grinding SD-30 attritor is now available for producing the raw materials used in lithium ion batteries. The attritor was reportedly designed with a special dry well gear reducer connected to the motor via a direct-drive coupling. A tilting assembly can facilitate removal of the shaft for maintenance and cleaning. Product is discharged through two plug valve assemblies with tungsten carbide-faced stainless steel bar grids. The cover is a stainless steel one-piece design with a floating Teflon seal for dust control. Visit www.unionprocess.com.
