To create actual products from the trimmings, manufacturers would pulverize them and then sinter the resulting powder into parts, a process that would preserve the nanocrystalline structure.
For decades, steelmakers have used highly polluting ovens to turn powdery coal and iron ore into chunks called coke and sinter , which are melted with superheated air to make iron.
Anderson points to new rules for sinter plants, which recover waste products from steel operations.
During 1957, an orange flocculent precipitate containing metal sulphides appeared in the spring pool and became incorporated in the marginal sinter .
The spring pool has a rim of grey siliceous sinter up to 2 m wide and 0.5m high.
typical blast-furnace burdens are 80% sinter, 20% ore
The increased sinter burden is also expected to enhance the productivity of blast furnaces, effecting a substantial reduction in the cost of sinter production and coke rate.
The pool has a narrow rim of subfossil siliceous sinter that rises up to 50 cm above water level.
From the beginning of the year, the factory has increased the coke and sinter output 1.2 times the figure at the end of last year by keeping furnaces in good conditions and machines in full-capacity operation.
This time is was sinter that was shipped to Algoma Steel.
