High Manganese Mantle Bowl Liner for Cone Crusher Machine

We are supplying the best quality cones to our customers. We produce these cones according to standard drawings, and many of them we already have patterns. We also produce cones according to customers drawings.We use high standard material for melting, and this help us can control the chemical component strictly, especially the P content. We use high standard spectrum analyze machine to check all chemical component for every melting, and keep the inspection sample for more than 3 years. To get higher wear performance, we use less than 30% scrap castings as melting material. Following is our scrap steel standard:Scrap steelChemical component %CPSSICarbon steel<0.25<0.02<0.03<0.15Alloy steel<0.25<0.02<0.03<0.15
We have different process for cones production, including sodium silica sand process and vacuum process. Sodium silica sand process is the most mature process for such high manganese steel cones and it is the most process been used in most of the foundries. Vacuum process is new process used in wear parts production. Buy this process we can get the best surface quality along with excellent wear resistant performance.
We strictly produce cones according to industry standard process. We can supplying cones with material: 18%Mn2%Cr,13%Mn2%Cr or 22%Mn2%Cr. With chemical component as follows:C %Si %Mn %P %S %Cr %Mn13Cr21.05-1.350.3-0.612-14≤0.06≤0.041.5-2.0Mn18Cr21.05-1.350.3-0.617-19≤0.06≤0.041.5-2.0Mn22Cr21.05-1.350.3-0.621-22≤0.06≤0.041.5-2.0
We set up qualified heat treatment facilities to help make better heat treatment. Castings from open the furnace gate to get into water need about 40S. In our best process we can control to 30S.We do inspection according customers requirement. And we give all the report that customers need for delivery to be sure all castings delivered by us are qualified.
