Definitions

  • the invention relates to a method for restoring the refractory lining in the upper zone of the wall region of a pan for casting and treating steel or similar metallurgical vessels and a device for carrying out the method.
  • the working lining can be bricked with refractory bricks or brought in as a refractory mass that solidifies into a monolithic layer. Combinations of these two types of delivery are also possible.
  • the infeed is often divided into zones which have different strengths of the working feed and / or differently resistant refractory types.
  • the working feed is either completely broken out and renewed at the end of the pan journey or repaired in the affected zones if the wear is only partially premature. If the working feed is exposed to chemically aggressive slag in the upper part of the pan about 1 m from the upper edge, the feed in the slag zone has to be broken out and renewed or repaired several times during a pan trip.
  • a delivery method is known in which the working feed of steel ladles is delivered with refractory concrete.
  • a template is required for the wall lining, which specifies the inner contour of the finished concrete lining. The mass is poured into the annular space between the permanent lining and the template.
  • Template that extends from the bottom to the top of the pan. For technical reasons, it can be divided in the middle. Mixers, pumps and internal vibrators are usually used to carry out the casting process. The shedding over a period of, for example, three hours must be carried out continuously to avoid possible hardening in the surface area. The vibrators are intended to prevent cavities and cavities from forming in order to achieve good compaction. If, for example, the mass has set after 24 hours, the template can be pulled out again.
  • the device for carrying out the method is designed in the manner set out in claims 2 to 4.
