Abstract
Shrink-fit assembly device for buildup of ceramic-coated liner and sleeve assemblies was tested and modified to develop desired temperatures and suitable heat distribution in sleeves which were heated. Nine different compositions of fiber metal reinforced ceramic compacts were produced for preliminary evaluation of suitability for extrusion liner use. Procedures were developed for welding short, hollow ceramic cylinders of high-strength metal carbides and borides to form a ceramic extrusion liner of suitable length. Disassembly tooling for rapid separation of shrink-fitted sleeves from a worn liner was designed, fabricated, and tested. Two complete 3-sleeve liner support assemblies were fabricated and tested. Preliminary extrusion testing of an alumina-coated liner was carried out, using SAE 4340 steel billets extruded to rod at 12:1 and 16:1 ratios. No coating wear was noted after extrusion of 3 billets. Required pressing force for SAE 4340 steel, heated to 2200 F and extruded at a 16:1 ratio, was only 200 tons.
