水ガラスプロセスによる高品質の鉄道鋳物製造

On the railroad, where power and speed meet, heavy-duty locomotives are powerful workhorses with a big job. Keeping them running safely and smoothly depends on railway castings like the axle box housing. The axle box housing acts as the essential link between the wheels and the main frame, handling huge amounts of weight and force. That’s why we focus on making strong and dependable axle box housings for all kinds of heavy locomotives, using advanced methods and materials to create this key component.

1. Core Railway Castings Process: The Water Glass Sand Casting Advantage

A superior product starts with a superior method. We employ the proven water glass sand casting process, which ensures our軸箱ハウジング are built to excel from the very start.

1.1 The Precision Sculptor

Sand offers excellent molding capabilities, which allows it to perfectly capture every detail of the mold. As a direct result, the final casting boasts precise dimensions, clear contours, and a smooth surface. Thanks to these qualities, it provides an ideal foundation for all subsequent machining processes.

1.2 The Integrity Guardian

By significantly reducing internal defects like gas pores and sand inclusions, the process acts as a strict quality controller. This meticulous focus on integrity ensures a dense and uniform metal structure, which in turn gives our 軸箱ハウジング the superior quality and toughness needed to reliably handle long-term impacts and vibrations.

2. Material Matters: Matching the Right Steel to Railway Castings

We understand that a single material cannot handle all operating conditions. したがって, we offer three quality cast steel grades to ensure each axle box housing has its perfect match.

2.1 ZG230-450 (ZG25 MnSteel): The Reliable Material for Railway Castings

As a carbon cast steel that balances strength and toughness excellently, this material is a practical and cost-effective choice. その結果, it reliably delivers consistent performance mile after mile, making it the ideal solution for standard locomotives operating in stable conditions.

2.2 ZG270-500: The Strength for Heavy Hauls

When locomotives pull heavier loads or face demanding routes, the demands on the axle box housing increase significantly. To meet this challenge, ZG270-500 provides a substantial boost in strength and hardness while maintaining good toughness, thereby making it the “powerhouse” for heavy-duty applications.

2.3 Grade B+C Steel: The Specialist for Harsh Conditions

For extreme environments like severe cold or high impact, we utilize the higher-grade B+C steel. さらに, this material undergoes stricter controls, which grants it exceptional low-temperature impact toughness and fatigue resistance. 結局のところ, it serves as the ultimate safeguard for locomotives operating at the limits.
