Abstract
Concerning the influences of sulphur in bunker C-oil the authers made an actual operating test with the continuous ingot-reheating furnace fired by an oil of high sulphur contents.
The results obtained were as follows:
(1) It produced more scale than by the use of an oil of low-sulphur contents.
(2) Scale on ingot surfaces became sticky.
(3) In the stronger oxidizing atmosphere of the furnace the scale on ingots was as much produced as in the oxidizing atmosphere without SO2, and did not become sticky.
These phenomena abovementioned depended no doubt upon several conditions, such as a character of reheating furnaces, draught schedule of rolling pass, etc.
But it was able to remove these phenomena from actual working by controlling the atmosphere of the furnace.
