Product catalog summary
Overview of Large-Scale Sintering Process
The document outlines an all-in-one cycle for sintering that includes debinding, vacuum sintering, low-pressure carburizing, and quenching. This process is designed to enhance productivity and component quality by integrating sintering and low-pressure carburizing in the same cell, thus avoiding temperature drops between phases. The process is clean, improves component density, and is suitable for chromium alloys.
ICBP® Furnaces for Sintered Components
ICBP® furnaces are used for high-temperature sintering (> 1,200 °C) and include Infracarb® carburizing and carbonitriding processes. These furnaces ensure clean parts free from oxidation, increase productivity, and save energy.
Dedicated Cell for Low-Pressure Sintering and Carburizing
The document describes a cell dedicated to low-pressure sintering and carburizing, with specific temperature stages: debinding at 650 °C, sintering at 1,200 °C, and low-pressure carburizing (LPC) at 950 - 1,050 °C, followed by gas quenching. The process involves controlled nitrogen and acetylene flows to achieve desired carbon content on the surface.
ICBP® Furnaces: All-in-One Cycle Features
The ICBP® furnaces offer flexibility with helium or nitrogen use, up to 20 bar pressure, and one-way or reversible flow. They improve quality by reducing deformation, ensuring post-treatment cleanliness, and providing reproducibility. The debinding phase duration is adjustable, and the system allows full control over temperature increases and atmosphere pressures. The vacuum environment prevents oxidation, and the system can treat chromium alloys at high temperatures.
Low-Pressure Carburizing and Carbonitriding
The LPC Infracarb® process is adapted for sintered materials, providing controlled and reproducible carburizing depth without intergranular oxidation. The process improves fatigue strength through low-pressure carbonitriding and Stop-Quench® processes.
