Abstract

PURPOSE:To improve heat resistance and oxidation resistance of an iron-based transporting member and to extend the life thereof by specifying the contents of Ni, Cr, Mo, Ti, Al, C, Nb, and Ta in said member. CONSTITUTION:The compsn. of the transporting member to be used for a heating furnace, etc. is constituted, by weight %, of 45-60% Ni, 15-26% Cr, 2-5% Mo, 0.5-2.5% Ti, 0.2-2% Al, <=0.1% C, 4.5-6% Nb and Ta and the balance Fe and inevitable impurities. This transporting member is formed by subjecting the alloy consisting of the above-mentioned compsn. to, for example, vacuum melting, casting, rolling, soln. heat treatment, etc., then forming an arbitrary shape. The transporting member has longer life and higher oxidation resistance as compared to the conventional stainless steel materials.

(Problems to be Solved by the Invention) Stainless steel materials conventionally used as conveying members do not necessarily have good heat resistance and oxidation resistance. In other words, there was a problem in that the corrosive atmosphere corroded due to the high temperature, resulting in a short life span. For example, when used as a mesh belt in a continuous furnace, the temperature of the sintering furnace is approximately 1
Since the temperature is 100°C, there are problems such as breakage during use, which increases the amount of time spent not producing industrial added value such as replacing parts.
