Calorized coated lance pipe

1,Calorized refractory oxygen lance pipe 2,Greater Efficiency 3,Cost Reduction

Calorized coated 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:

1,Excellent Refractoriness: resistance against heat, erosion and spalling

2,Speedy De-Carburization: because of longer life and superior heat resistance. There is no decease in its strength and pipe remains straight resulting in optimum metal oxygen interaction

3,Greater Efficiency: of reaction with oxygen, pipes can be inserted in liquid metals with / without bending which avoids bubbling of oxygen near surface of metal or slag

4,Cost Reduction: considering above advantages, various saving can be expected as electric power, decrease in consumption of electrodes, lower melting time, saving in cost of pipes
