Custom High Chromium Alloy Steel Blow Bars for Impact Crusher Wear Parts

Custom High Chromium Alloy Steel Blow Bars for Impact Crusher Wear Parts

Product Description

We are a reliable manufacturer of high-end castings for the mining and aggregate industries. Our core capabilities cover High Manganese Steel, High Chrome, Alloy Steel, and Ductile Iron, supplying critical wear components for Ball Mills, Jaw Crushers, and SAG/AG Mills. This blow bar series is crafted with advanced metallurgical processes, engineered for superior wear resistance and impact absorption in various crushing applications.

Applications

• Impact Crusher Blow Bars: Designed for primary and secondary impact crushing of granite, basalt, river pebbles, iron ore, and limestone.

• Crushing Equipment Components: Suitable for both fixed and mobile crushing plants across mining, sand, and gravel operations.

• Aggregate Processing: Ensures a long operational window even in high-hardness material crushing scenarios, reducing downtime and replacement costs.

Production and Quality Inspection

We employ a rigorous multi-stage quality control system to ensure reliable performance and traceability. Please refer to the following inspection images:

1. Chemical Composition Analysis and Heat Treatment: We accurately control the content of Cr, Mn, Mo, and Ni using a direct-reading spectrometer to ensure alloy purity. The castings then undergo precise water toughening or quenching heat treatment to achieve an ideal austenitic structure and optimize hardness and toughness.

2. Hardness Testing and 3D Scanning: We systematically perform Rockwell or Brinell hardness tests on multiple locations to guarantee uniform wear resistance. Additionally, 3D scanning verifies the complex geometric profiles and installation dimensions against the original CAD design.

3. Non-Destructive Testing MT and UT: To ensure internal structural integrity, we perform Magnetic Particle Testing (MT) to detect surface defects and Ultrasonic Testing (UT) to identify internal porosity or micro-cracks. For specific materials with low magnetic permeability, we also utilize Penetrant Testing (PT) as a supplementary method.

4. Dimensional Inspection and Metallographic Analysis: Precision gauges and check fixtures verify slot widths and mounting holes for perfect fit. Metallographic analysis examines the carbide distribution and grain size to confirm optimal material structure.

Support and Services

• Custom Drawings: We accept customer drawings and offer OEM/ODM services with custom sizes and weight specs.

• Material Optimization: Our engineers assist in selecting the ideal material (Mn13Cr2, Mn18Cr2, Cr26, etc.) based on your specific working conditions to maximize lifespan.

• Traceability: We maintain casting heat number records for full batch traceability.

Packing and Shipping

• Packing: Standard export wooden pallets, steel frames, or custom crates, secured with straps to prevent movement during transit.

• Protection: Anti-rust oil treatment, VCI paper wrapping, and plastic film sealing to protect against corrosion and moisture during ocean freight.

• Shipping: Suitable for heavy sea freight; we support FOB, CIF, and DDP terms, ensuring safe and timely delivery to your port.
