In the metallurgical shop of the Polymetals Production branch of Uralelectromed JSC (an enterprise of the UMMC metallurgical complex), a place was organized for cleaning ladles from deposits. This will significantly reduce the labor costs of crane operators and slingers.
- Before organizing the site for cutting the crusts, we had to use a crane to move the bucket two hundred meters to the place of knocking out and then back, - says the acting director. head of the converter department of the metallurgical shop of the branch Leonid Vovk. - Due to the fact that now everything is in one place, in the immediate vicinity of the metallurgical units, the time for these operations has been reduced by 15-20 minutes. Considering that during a shift, depending on the technological process, we have to knock out four to seven times, the innovation significantly saves labor and energy resources, and allows you to more quickly prepare ladles for receiving melts.
The first stage optimization was the commissioning of an installation for cleaning ladles from scabs (November 2019). Due to this, it was possible to completely eliminate the mechanical stress experienced by the crane during a dynamic impact during the process of knocking out the bucket. The optimal location of the unit in the center of the workshop building made it possible to access any of the three operating cranes.
The second stage took place in July this year, when a crusting area was set up next to the ladle cleaning unit. Now, after knocking out, the crusts are immediately loaded into the tray and returned to production.
The site is a reinforced concrete base with a U-shaped protective fence. The project was prepared by the design department of the branch, the metal structures were made by the forces of the centralized equipment repair shop, and the concrete work was carried out by the refractory workers of the metallurgical shop.
