WJ85640 Modern Heat Treatment Technology Improves the Production of Malleable Cast Iron Metallurgia 1985, vol.52, No.2, P20 (English) This paper presents a new type of intermittent electric furnace for malleable cast iron annealing. The author first discusses the conventional heat treatment process, equipment and its disadvantages of malleable iron, especially black heart malleable iron. Then it briefly introduces the structural features of the hood electric stove newly designed by cooper heat furnace company. The furnace top cover with low thermal inertia lining material, the ribbon heating element are all arranged in the top cover; between the cover and the bottom of the furnace with a double sand seal air tight knot
