✦ Synopsis

THE Bureau of Mines recently completed an investigation of the gas composition, temperature, and pressure at a series of planes in a blast furnace making foundry iron in the southern district. Samples of coke, metal, slag, limestone, and stock were recovered from points between the tuyere plane and stock line. If complete and representative samples of stock could be obtained from various points across a series of planes between the stock line and tuyere level while the furnace is in operation, analyses of these samples would present a clear picture of most of the steps in the reduction process. Aside from giving the position of the zones of reduction, calcination, and slag formation, the samples are valuable in determining where the iron acquires its carbon, sulphur, phosphorus, manganese, and silicon.

A complete description of the tests and results obtained are given in Technical Paper 397, which recently appeared.
