Abstract
The authors studied the permanent-wall-type furnace with compulsory cooling. In this paper, the experimental results on the small converter with water cooling tuyere and jackets were reported.
The experiments were carried out with small side blown converter and its capacity was 50kg. The results obtained were summarized as follows:
1. Low-carbon, high-quality steel can be produced from various kinds of pig iron with the aid of pure oxygen blowing in the water cooling small converter.
2. In this process, the general characteristics of heats were similar to the normal converter process, and several advantages were found; reduction of slag amount, longer life of the converter, etc.
3. Thickness of permanent refractory layer obtained was 5-10mm and this thin layer would be remained as neutral lining the blowing.
