AB - THE STRUCTURE AND STRENGTH OF IRON CASTINGS AFTER REENAMELING Yu. P. Tsap and M. A, Giukhovskii UDC 669.13:[620.192.4 + 620.174] :666.293 During enameling cast apparatus undergoes repeated heating (preliminary annealing and burning of the base and enamel) to temperatures of 870-920~ for 4-5 h. In practice, however, there occur cases when defects appear during enameling- air pockets, blisters, pricks, etc. After removal of the defective enamel coating the product is again enameled (this operation is known as reenameling). Because of repeated en- ameling the total exposure of an object to high temperatures can be as long as 10-15 h or even more. Metallographic studies of the cross section of apparatus and sample wails have revealed the dynamics of the process of microstructural changes in cast iron after repeated heating during enameling. The me- mm HB Obend, -"Kg~/mm 2 chanical properties of gray iron are determined mainly by the presence 4n - of the graphite component [1]. The change in mechanical properties af- 2,5' 200 3 j ,~, ) ] ter repeated alternating high-temperature heating depends chiefly on changes in the properties of the metal base and not of graphite, since the form of graphite changes little on heating. in
