New fireproof paint developed
The researchers of the institute intensified their study to obtain substances that can be used as raw materials of the fireproof paint. In the course, they obtained a substance with refractoriness of over 1,000℃ which does not melt by molten iron and solved the problem of bonding agent and auxiliary additives according to the actual conditions.
The technicians of blast furnace workshop No. 1 of Kim Chaek Iron and Steel Complex proved through several rounds of test production that the newly-developed fireproof paint lengthens the life of refractory.
Another progress was made in the centrifugal casting process of the steel casting workshop to increase the production while saving electricity which was used a lot in the course of stripping.
