Engineered specifically for WAM and EUROLON concrete mixers, our high-chromium scraper blades are designed to tackle the dual challenges of extreme abrasion and material buildup in demanding mixing applications. Manufactured under ISO 9001-certified processes, each blade is precision-cast using advanced lost-foam casting (EPC) and vertical flaskless molding technologies. This integrated approach achieves an exceptional material density of 99.8%, eliminating micro-porosity and ensuring structural integrity that prevents cracking and deformation under heavy loads. The result is a blade that not only lasts longer but also maintains its precise geometry for optimal performance throughout its service life.
The blades are crafted from a proprietary high-chromium alloy featuring 29-32% chromium content, enhanced with strategic additions of molybdenum and nickel. This specific composition is refined in our medium-frequency induction furnaces, creating a uniform and dense carbide network that delivers a superior surface hardness of 58-64 HRC. Independent laboratory tests verify these scraper blades provide 4.5x better wear resistance than conventional blades, reliably handling over 280,000 cubic meters of concrete mixing – a performance that translates to a 50% longer service life. This is backed by a tensile strength of 470 N/mm² and an impact toughness of ≥7.8 J/cm², ensuring resilience against sudden impacts and fatigue.
Our digital engineering process incorporates Finite Element Analysis (FEA) to optimize the blade's geometry and stress distribution, significantly reducing failure points in high-stress areas. The unique edge profile and surface treatment are specifically designed to minimize material adhesion, reducing concrete buildup by over 65% and ensuring consistent mixing efficiency while lowering the power required for operation. Each blade is CNC-machined to a tolerance of ±0.15mm, guaranteeing a perfect fit and seamless installation in WAM and EUROLON mixers. Backed by comprehensive technical support, these scraper blades are the definitive solution for operations seeking to maximize uptime, reduce maintenance costs, and achieve a lower total cost of ownership.
