lead refining, kettle, construction, exploitation, life time
Abstract
Continuous process, as well as refining capacity of lead is highly dependent on the quality of kettles for refining lead. The kettles are made from special kettles plate and are generally spherical in shape. Quality kettle plate, the method of construction of the kettle, the kettle operation mode, proper maintenance regime technological refining process is represented by factors of which depends on the overall lifetime of the kettle. The quality of the welding electrode and method significantly influences the lifetime of the kettle, not only in the preparation of the kettle, but also in its reparation.
