the object of increasing the area of the tuyeres, and thus the amount
of the blast per unit of time. In the furnace thus improved (see the
Figure, next side) was carried out on the 18th July 1858 the first
completely successful Bessemer steel blowing. The problem was solved.
One now obtained an easily flowing steel, easily tapped, which exhibited
excellent qualities when subjected to the test forging. The successful issue
of the experiments revived people’s faith in the Bessemer process. It
was carried on at Edsken until March 1866, when these works were
shut down. In the meantime the Högbo Company had been constituted
with Göransson as its manager, and in 1862 and the year following
this Company built a new iron work, Sandviken, with a Bessemer plant.
It was here that the first Swedish tilt furnaces or converters were erected,
and the blowings were superintended by the engineers, C. Lundvilc and
O. Kollberg. The latter subjected the process to a thorough scientific
analysis, and ascertained the conditions under which it could be most
effectively carried out.
Once elaborated at Edsken, the process was introduced into several
other Swedish iron works. It was deemed particularly well adapted for
Sweden, with her pure ores and her abundance of water power for
driving the blowing engines. At first stationary furnaces were every-
