Polymetals Production has launched an installation for cleaning ladles from deposits
Kirovgrad (Sverdlovsk Region)
In the metallurgical shop of the "Production of polymetals " JSC "Uralelectromed " (an enterprise of the UMMC metallurgical complex), an installation for cleaning ladles from deposits was put into operation. The cost of manufacturing and installing new equipment exceeded 9.1 million rubles.
The own development of the design and engineering department of the PPM was implemented by the contractor and workers of the metallurgical workshop. The largest amount of work fell on the preparation and concreting of the pit, as well as the installation of metal structures. The weight of the cradle, on which the knockout bucket is installed, is 8.5 tons.
- The knockout unit in the metallurgical shop is one of the main objects of capital construction of our enterprise this year, - says the head of the metallurgical shop PPM Dmitry Khristolyubov. - With the introduction of it into operation, we completely eliminated the mechanical stress experienced by the crane during a dynamic impact in the process of knocking out the bucket. In addition, the optimal location of the unit in the center of the workshop building allows any of the three cranes operating in the workshop to access it. The slinger, who controls the knockout process, now has less movement.
The new unit is a cradle set on a concrete foundation. A bucket is installed on it with a crane, and knocking out is done without the participation of the crane. The bed is in a suspended state, the so-called "beacon" version, to soften the impact from the wedge. A wedge weighing 2-2.4 tons is suspended on special supports, which is pulled by a winch, then lowered onto the bow of the bucket and removes crusts and deposits from the walls. Each shift, metallurgists clean 5-6 ladles, the weight of one ladle is from 14 tons.
With the installation of a new unit, the process of pouring chalk solution on ladles was also optimized, which prevents the melt from welding to the ladle walls. It will now be produced in close proximity to the new plant, saving time in preparing the ladle to receive the melt.
