Title:
HEAT-REFLECTING PLATE FOR CARBURIZING ATMOSPHERIC FURNACE AND CARBURIZING TREATMENT METHOD
Document Type and Number:
Japanese Patent JP2012214827
Kind Code:
A
Abstract:
To provide a heat-reflecting plate which maintains the heat reflectance even if it is used for a long time in a carburizing atmosphere or oxidative atmosphere and in a carburizing atmospheric furnace heated to a high temperature, contributes to energy saving and is relatively low cost.
The heat-reflecting plate for a carburizing atmospheric furnace is formed from a nickel-based alloy super heat resistant alloy having heat reflectance of 50% or more. It is preferable that the nickel-based alloy super heat resistant alloy contains chromium and aluminum.
