METSO · Part Details
Main Frame Liner
Mainframe Liner
Identify parts for Metso cone crushers, check models and drawing, confirm materials and processes, and submit an inquiry.
Equipment and Applicable Models
Identify the installed machine model and key dimensions, then check the drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP Series (HP100-HP800), GP Series (GP100-GP550) and MP Series
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
High-Manganese Steel Mn13Cr2
Standard material, solution-treated and water-quenched to HB 200-250, for locations subject to impact
Hardox 400 Wear-Resistant Steel Plate
HB 370-430, for areas dominated by dust erosion and sliding wear
Wear-resistant steel plate specified by the drawing
The material, hardness and surface treatment must meet the drawing requirements for this position.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Rebounding material causes local impact wear
- Dust erosion causes widespread, relatively uniform thinning
- Wear around bolt fixing points causes the liner to loosen
Replacement criteria
Assess replacement against the liner remaining-thickness limit in the drawing. Replace if through-cracks occur. If wear reaches the main frame substrate, replace immediately and assess frame repair requirements.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
Mn13Cr2 high-manganese steel, Hardox 400 wear plate, or wear-resistant steel plate specified by the drawing
Heat Treatment Condition
Solution heat treatment with water quenching. Final hardness and microstructure must meet the drawing and agreed technical specification.
Composite / Hardfacing Requirements
Weld Hardox wear plate using an approved procedure for the grade and thickness. Select consumables, preheat, interpass temperature and repair limits in accordance with the manufacturer's recommendations and the drawing.
Dimensions and Inspection
Manufacture to drawings produced from part measurements or supplied by the customer. Critical mating surface tolerances follow OEM requirements. Use UT/MT inspection to assess castings for shrinkage porosity and cracks against the agreed acceptance criteria.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
