| Description |
English: In November 1944 the old no. 1 blast furnace was abandoned, and a new one came into operation which was designed to operate on charcoal. The main features of this furnace, which has been called blast furnace No. 2, and it was designed for a production of 60 tons a day. This blast furnace No. 2 was built with a suitable height for making use of the existing elevator equipment and the loading platform. It is estimated that it should have been some two metres less.
Until December 1950 the Corral blast furnace was operated by ESVAL, and used charcoal to which a small percentage of gas coke from the gas works in Concepción was added. During this period output totaled 87,000 tons, giving an annual average of 14,000 tons. The highest annual production was 18,600 tons, in 1949, while the highest monthly total was 2,084 tons, in January 1949. The highest total for one day was 89 tons, on 16 January 1949. All these figures include from 8 to 10% of scraps. In 1951 production amounted to 19,77 0 tons. By July 1952, 12,950 tons had been produced, and maintenance of that rate would imply an annual rate of 22,200 tons. |
