Methods of Steel Casting
Bessemer's method for making continuous sheets consisted in running molten steel between two water-cooled steel rolls, separated a suitable distance; the speed of the rolls was regulated according to the thickness of the sheet. In Whiteley's process for the production of plates, molten steel was run into a revolving cylinder and formed a shell which was taken out, cut open by a saw, and then rolled down.

Hot Blast Stoves in Steel Making
A vacuum or exhaust tuyere is one from which the water is sucked out, instead of being forced through, to lessen the leakage in the furnace if the tuyere breaks. The blast from the stoves is led into a large pipe (bustle pipe) surrounding the furnace and above the tuyeres with which it is connected.

General Steel Making: The Cementation Process
This phenomenon is absent when steel bars are treated; both products are known as cement (cemented) bars or cement steel. Bars desired of very high carbon may be retreated, and are known as doubly converted bars or glazed bars. Since the carbon penetrates from the outside inward, the percentage will decrease progressively to the center.

Crucibles in the General Steel Making Process
Graphite crucibles can be made to contain a heavier charge, and also last a greater number of heats. They are made of a mixture of Ceylon graphite, German clay and pure sand.

Large furnaces are about 80 to 200 feet high, have an output up to 600 or 700 (commonly 300 to 600) tons per day, and employ blast at a pressure of 5 to 25 (usually 1 to 15) pounds per square inch, and at a temperature of about 900° to 1400° F. (485° to 7600 C.)
