improve the quality of stainless steel pipe fittings

 improve the quality of stainless steel pipe fittingscasting and refining furnaces are generally
   Stainless steel pipe fittings from the ingot into slabcomplementary, and the chemical composition and
technique. And because the quality of continuoustemperature of molten steel, there are strict
casting control means perfect, has become arequirements; to prevent the secondary oxidation of
