Definitions

• the main problem in the manufacture of a cold metal is an increase in quality and an increase in production output. ⁇ Significantly, this is divided into a process metal, 20, which is sold in the press. Increasing the quality of our products is subject to the same heating conditions, so that we all have the same temperature, we are free to eat. The increase in furnace productivity substantially depends on the intensity of the 25 heating processes of the burned metal.
• Option of the boiler and the muffle, and the latter is a shielding gas supplied in a convenient furnace. Shielding gas is protected by the operation of the circulating fan while heating the muffle;

• Such a feature of the invert ring is due to the strain on the intensification of the transfer of investment to the party. Shielding gas, if it is not connected to the outside of the ring, is subject to high intermittent interruptions due to the loss of life. The large range of interconnections between the arrester switches off the entire entire range of the process, and the process is free of damage to them.
• the minimum gap between rolls is selected in the range:
• the difference between the size of the receiver makes it possible to increase the space of the owners, by which the emission of the muffle is completely free, which is free of charge.
• One of the variants of the intercostal hemisphere has a length equal to 0.5-0.9 for the long rib.
