Ceramic coated lance pipe

Calorized coated pipe combines the actual need of steel-making in EAF , easily operate, less consumption, high refractoriness

Calorized refractory oxygen lance pipe

Calorized refractory oxygen lance pipe. (PS series), the PS series is composed of five layers as steel pipe,calorizing inside and outside,coating inside and outside , and developed by the S series of products. It combines the actual need of steel-making in EAF , easily operate, less consumption, high refractoriness. It is an agglomeration of general coating oxygen pipe and calorized oxygen lance pipe, and mainly used for blowing oxygen/carbon in EAF, And Calorized refractory oxygen lance pipe are coated with refractory/ceramic on the outside and inside pipes.

The Calorized refractory oxygen lance pipe is an heat treatment processibility for pipe in steel-making, except general Degreasing,Pickling,rinse,flux,stoving,Hot dip aluminum liquid,it is also a technics of hot dip Aluminium and Diffusion to achieve a coating thickness greater than 0.2 mm, then gas testing,wired,Phosphoric acid rinse and recoated ,the coating has special formula.Its various characteristics as below:

 Technical parameters:
