Metal intensity of equipment. For molding lines with a capacity of 70 thousand. M2 of the total area per year is least of all consumed metal on a cassette line with one -stage heat treatment, and with a power of 140 and 280 thousand. M2 on the cassette-conveyor. This is explained by the fact that the molding installation of the line moving shields along with forms by 28 29% is easier than cassette machines and 1.5-2 times easier than equipment of other technological lines. The most metal -intensive are, respectively, conveyor with vertical cameras and conveyor with slit multi -tiered cameras. The difference in the metal consumption in the indicated least and the most metal -intensive lines is 27% (70), 48% (140) and 46% (280 thousand. m2).
The overwhelming part of the metal falls on the share of pallets, shapes, on -board and cassettes. Regardless of the production and power of the lines, the metal consumption of the specified equipment group is 66-75% of the total consumption, and on the cassette lines with recreation cameras, the weight of the cassettes reaches 80%.
