DRI Tubes

Industry Development Background

SETTING

Industry Background

During operation, reformer tubes are subjected to high temperatures, high pressures, and corrosive gases. Therefore, the tube material must possess oxidation resistance, carburization resistance, coking resistance, and high-temperature strength. Currently, MIDREX designs are continuously increasing the furnace temperature of the reformer, requiring the tubes to withstand temperatures above 1185℃.  Clearly, traditional materials cannot meet this temperature resistance requirement.

Industry Pain Points

Insufficient temperature resistance level

The temperature of traditional materials;
Unable to meet the temperature requirements of MIDREX design.

Easy to creep and fracture

Cracks and voids appeared inside the reformer tube;
The cavities will develop into large cracks;
The crack reaches the inner wall and the conversion tube fails.

Serious industrial pollution

Increase CO₂;
Increased emissions of air pollution.
