The technologies and equipment of JSC EZOCM allow manufacturing crucibles in the wide range of diameters with a minimum number of welds:
- solid-drawn spherical bottom from a solid billet;
- cylindrical part of the crucible with one longitudinal weld.
The advantages of such crucibles are their greater resistance to aggressive substances and longer service life.
In addition to crucibles, stirrers, drain and overflow pipes, nozzles, flanges, bellows and other devices can be manufactured upon the customer's request.
