42CrNiMo 18CrNiMo Quality Forging Steels Forged Alloy Metal Forging Products Cement Grinding Gear

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:

• Forging weight range: 100KG – 7,000KG

• Forging methods: open-die,and free forging

• Gear blanks forged to near-net shape, reducing machining time and material waste

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)

1. 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.

2. 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.

3. Which industrial sectors are the primary beneficiaries of your forged products? We cater to a diverse array of critical industries, including wind power generation, heavy machinery manufacturing, port infrastructure, power transmission systems, and various others.

4. What are the typical timeframes for the completion and dispatch of orders? For items readily available in our inventory, the standard lead time is approximately 30 days. For custom-manufactured orders, the timeframe generally spans 40 to 45 days.

5. Could you provide information on the geographical location of your manufacturing facility and shipping hub? Our production plant is situated in Changzhou City, strategically located near Shanghai, and we utilize the Port of Shanghai for our shipping logistics.
