Definitions

• the invention is no longer subject to pressure treatment, and more precisely - to technology and facilities for the flexibility of steel,
• the most successful invention can be used in the manufacture of a ship's wiring and large-sized vessels, for example, a wreck.
• Such temperature of heating the metal allows you to get a bend of the metal in the region of its heating, which is smooth.
• the metal sheet is simply heated to a temperature of over 600 ° for each.
• the metal sheet is bent in places of heating, using the power of the actual metal weight.
• the consensus is that the quick metal is easily heated by high speed currents at a temperature of 900 ° C. This is avoided at the time of heating to a solution in the vicinity of the sheet thickness with a temperature of °00 ° C / t. E. 700-800 ° C /, and on the other side of the road - with a differential of 400 ° C / t.e. 400-500 ° C /.
