42CrMo, 42CrNiMo, 18CrNiMo Forged Alloy Steel Cement Grinding Gear. We supply precision-forged alloy steel gears made from 42CrMo, 42CrNiMo, and 18CrNiMo, specifically developed for cement grinding machinery and heavy-duty transmission systems. These forged gears deliver superior toughness, wear resistance, and fatigue strength, ensuring reliable operation under high loads and harsh working conditions typical of the cement industry.
Material Options:
42CrMo – A high-strength alloy steel with excellent hardenability and impact resistance, widely used for large transmission gears.
42CrNiMo – A nickel-molybdenum alloy steel offering enhanced fatigue strength and toughness for dynamically loaded components.
18CrNiMo – A top-grade carburizing steel providing deep case hardening, superior wear resistance, and long service life in gear applications.
Key Features:
Custom sizes and module options available
Precision forging ensures fiber continuity and uniform structure
Heat treated to optimize gear performance
Optional rough or semi-finished machining per drawing
100% Ultrasonic Testing (UT) and Magnetic Particle Inspection (MPI)
Material certification and mechanical property reports provided
Applications:
Cement grinding mill gearboxes
Main drive gears and ring gears
Kiln drives and rotary machinery
Gear transmission systems in heavy industries
Manufacturing Highlights:

The steel forgings production flow:
Raw material steel ingot into warehouse(test the chemical composition) → Cutting→ Heating(Furnace temperature test) → Heat treatment after forging(Furnace temperature test) Discharge the furnace(blank inspection)→ Machining→ Inspection(UT,MT,Visal dimension, hardness)→ QT→ Inspection(UT, mechanical properties, hardness, grain size)→ Finish machining→ Inspection (dimension)→ Packing and Marking(steel stamp, mark)→ Storage Shipment.
Frequently Asked Questions (FAQs)
What is the typical weight spectrum of the forged components you manufacture? Our forging capabilities encompass a range of components weighing from 100 kilograms up to 7 metric tons.
Do you handle downstream processing such as thermal treatment and material removal? Indeed, we provide comprehensive in-house services for heat treatment, encompassing both preliminary and final machining operations.
