Material can replace agate for grinding
conlpsnents are fired at about ltO0 deg c to ei+ect caicination and although gee metrical shapes have been tried, the researchers now favOur free forms hI sizes rangiiig from 7 mm to 10 mm. The aggregats adheres well In a bitumen binder and will abrade rather than PO_ lish, which greatly extends its skid-r& s1sting life.
has designed continuous vacuum heat treating and sintering jyatems made up of modular components which are as sembled to perform particular heat trea ting functions. The furnace system consists of an atmosphere to vacuum n vestlbuie section folfotied by a heating chamber, and a combination ofi quench and final L va. cuum to atmosphere vestibule. For sin+ tering or brazing. the oif quench rn@ dule can be removed and a~ extended coolina chamber added. Furnace ooera tion iS completely automatic. ’ The new system can handle 60@1OOtJ pounds of parts per hour. Normal operatios temperatures ran99 uD to 3OOO F, but graphiie heating elements have temperature capabilities into the 5000 F range, Hayes claims. The system solves production bottlenecks associated with patch-type equip ment and conserves energy by eliminating the need for castfy atmosphere gases. Power savings result because p+ wer is on only during actual heat treating or sintering. Contact C. 1. Hayes Inc.. Crar!slon. Rhode Island for details. ??

FIERE GAINS STRENGTH FROM NEEDLE PROCESS A ceramic-flbre insuietlng material cailed Ourablanket. which has high tensile strength derived from a needling pr@ cess, has been developed by the Garb rundum Company for use up to 1260%. The blanket CDmphments the company’s existing range of Flberfrax H and L@ Con blankets and felts, and is suitable for hot-face linings and back-up insuia tion in kilns. Compared with these products tha new and ma,terlal, corltaining 50% alumina 50% silica. offers increased handling strength and flexibility. and is suitable for dlfficuit insulation jobs Involving lat. ae areas or confined spaces. as well as rot wrapping around shall radii. The hfanket IS produced In four standard thicknesses from 6.4 mm to 38 mm. Standard densities are 64. 96 and t28 kgjm’.

A new material composed of 97 per cent ZrOl has been developed by the German concern Alfred Fritsch 8 Co. for grinding!wearing parts of analytical pulverisers and replaces the rare and kxpensive semiprecious s&eagate1 Compared with agate IWO,. of densitv 2.6 g/cm’1 end sititered corundum [A&O;, of density 3.7 g/cm,) zircon oxide has a higher density of 5.7 g/cm’ and thus generates higher impact energy. In gravity and centrifuqal milts. zircon oxide’s -abrasion is comparable to hard metal [WC-t CO). Grinding ves sels up to 500 ml v&me and grinding balls up to 50 mm diameter are made.
