During the period under consideration, the metal consumption when rolling beams and channels on medium-grade camps did not decrease at all, and even there is a slight tendency to increase it.
By design, small-grade mills are divided mainly into three types: linear, continuous and semi-intake. The difference in the design and the location of the working strokes of small -grade mills does not always affect the flow of metal. Therefore, the change in consumables for all three types of stani is given in one figure.
On linear small -grade stations of the outdated structure 330 and 280 plants. Dzerzhinsky, the lowest consumables are observed when rolling small varieties from both boiling and calm steel. This is explained by small waste of metal into cargo and trim, which is a consequence of minor rolling speeds and the absence of intermediate heating when the workpiece is received from the crimping cage. In addition, the camps 330 and 280 of the factory. Dzerzhinsky receive a large number of measuring blanks, which significantly reduces the waste of metal waste into a cut during cutting of suitable rental. For high -quality work of the enterprise you will need reliable equipment.
There are 280 Kuznetsk plant, as well as 330 and 280 Makeevsky Metallurgical Plant, the metal consumption is much higher than on the identical camps of the plant by them. Dzerzhinsky. At KMK, this is a consequence of large metal waste into collapse due to insufficient sizes of rolling fields and refrigerator, as well as due to the lack of volatile scissors.
