Development of continuous type high-speed carburizing furnace

摘要

In our manufacturing plant, each production process has been improved from the point of environmental protection (energy-saving). Especially, much energy is consumed in the heat treatment process, and so, this reduction is an urgent and indispensable subject. In this paper, development of a continuous type high-speed carburizing furnace is reported as an example of energy-saving approach. This furnace has been developed with adoption of high carbon oxide carburizing technique in collaboration with Koyo Thermo Systems Co., Ltd. This furnace has been already installed in the plant, and reduction effect of 54% carburizing time, and 50% energy cost has been achieved comparing with a conventional process.
