Abstract

1457415 Sintering green steel strip BRITISH STEEL CORP 21 May 1974 [21 May 1973] 24154/73 Heading C7D Green strip formed by milling Cr containing steel powder is passed continuously to and through a furnace where it is sintered at 850-1400‹C in a non oxidizing N 2 containing gas to increase the N2 content. The gas may be cracked NH 3 or a mixture of A and up to 75 wt. per cent N2. 18/8 stainless steel powder 2 fed from bed 4 and hopper 5 is rolled at 6 and sintered in furnace 8 in cracked NH 3 . The gas is recirculated through the furnace and make up gas is added to the circuit.
