Mantle, bowl liner, jaw plate and blow bar castings for Metso HP, GP, MP, C and NP series. Manganese and chrome grades, made to drawing or sample.
We cast wear parts for the Metso cone, jaw and impact ranges. 41 models, spread over HP, GP, MP, C and NP. Some come off patterns we hold. Most are poured to a drawing or to a sample the customer sends in, which means the model number alone will not get you a price.
Enquiries mostly arrive after a liner has failed early. In our experience the alloy is rarely the reason. More often it is the chamber, the feed, or a backing that was poured with voids behind it.
The HP range carries six cavity options from extra coarse down to fine. A liner that measures right but sits one cavity step away from the duty will wear into a step at the lower third of the bowl, because the reduction is being done in the wrong part of the chamber. We ask for the cavity code before we quote. Asking after the complaint is too late to help anyone.
One failure we see often is not a wear part problem at all. The moving cone goes back in without seating cleanly on the eccentric, the bushing carries the load unevenly, and the inner wall of the bushing wears through in a fraction of the expected hours. The liner looks fine. The operator reports a strange noise and a drop in power draw. If you send a worn bushing with a worn liner, we will say so rather than quote you a new liner.
Mn18Cr2 is our default for HP and GP mantle and bowl liner. It work-hardens under the impact those chambers see and keeps a tough core. Mn22Cr2 buys toughness in a coarse chamber taking a large top size, and gives up some abrasion resistance to get it. High chrome on a primary cone is the wrong call. It is harder, it holds that hardness, and it cracks. Hardness on its own is not a specification.
No, and we do not claim to. Part of the range runs from patterns in our own shop, the rest is made to drawing or to a sample you send. Every model row states which basis applies, so a quotation request does not turn into a surprise three weeks later.
We hold the specified grade and report what we measured on the casting. What we will not promise is identical service life. Life depends on chamber, feed and setting as much as on the steel.
A drawing, a sample, or an original part number together with the cavity code and the machine model. Weight and principal dimensions follow from the drawing. Without it any weight we gave you would be a guess, and you would recieve a part that does not fit.
