Industry Knowledge of FV Series Conveyor Chain

The FV series is a DIN metric heavy-duty conveyor chain, which is the mainstream conveyor chain standard for the European market. Classified into the sleeve and roller conveyor chain category, it is specially designed for low-speed, long-distance and heavy-load conveying of bulk materials and industrial workpieces, and is widely applied in B2B foreign trade and industrial conveying systems worldwide.

1. Classification & Core Features of FV Series Chains

The FV series consists of three core models to adapt to different working conditions, with complete specifications ranging from FV40 to FV180:

• FV (Standard Solid Pin Type): The basic and most widely used model with integrated solid pins. It features sturdy structural stability and two strength grades (standard and reinforced). Various accessories such as bent plates, straight plates, K/M type attachment plates, push blocks and scrapers can be installed flexibly at intervals or on single/double sides.

• FVC (Hollow Pin Type): Designed with through-hole hollow pins, allowing transverse installation of bolts, cross bars and hoppers. It is ideal for conveyor systems equipped with cross baffles and bucket conveying, enabling convenient on-site tooling assembly and modification.

• FVT (Large Roller & Raised Plate Type): Adopts enlarged rollers and raised inner chain plates, which effectively reduce friction with guide rails. It is the preferred model for rail walking and scraper conveyor equipment, with optional standard and high-strength grades.

Pitch Specification: Standard metric pitches from 40mm to 500mm. The chain number directly corresponds to the minimum ultimate tensile load (e.g., FV112 features a minimum breaking load of 112kN).

2. Material & Heat Treatment Technology

FV series conveyor chains adopt high-strength industrial materials and precise heat treatment processes to ensure excellent wear resistance, impact resistance and durability under harsh working conditions:

• Pin: Made of 40Cr/42CrMo alloy steel with high-frequency quenching and tempering treatment, achieving high hardness, strong shear resistance and impact resistance.

• Sleeve: Adopts precision seamless steel tubes with carburizing quenching process for smooth operation and excellent anti-wear performance.

• Chain Plate: Made of high-strength medium-thick steel plates with quenching and tempering treatment, ensuring high tensile strength and structural toughness.

• Roller: Subject to carburizing hardening treatment; optional configurations include standard rollers, large rollers and flange rollers.

• Anti-corrosion Version: SSFV stainless steel series (304/316L) is available for food processing, chemical and other corrosive environments.

Standard connection modes include riveting and circlip fixing, supporting customized accessory welding and stamping for diverse conveying requirements.

3. Typical Application Industries & Working Conditions

FV conveyor chains are applicable to low-speed (≤0.6m/s), heavy-load, dusty and impact-prone working scenarios, and are not suitable for high-speed transmission equipment. The main application fields are as follows:

• New energy & environmental protection: Biomass fuel conveying, garbage recycling and waste steel conveying

• Building materials & energy: Cement plants, thermal power plant ash removal, sand and aggregate conveying

• Wood & metallurgy: Wood processing, plate conveying, steel structure workpiece transmission

• Food & agriculture: Grain, feed and packaging production line conveying

• General industry: Scraper conveyors, buried scraper conveying equipment and heavy-duty material handling systems

4. Core Selection Guidelines

• Conveying Speed: Exclusive for low-speed conveying; not recommended for high-speed transmission scenarios.

• Load Capacity: Calculate the maximum chain tension with a safety factor of 5-8 times; reinforced grade is preferred for long-term heavy-load operation.

• Accessory Matching: Select FV solid pin type for conventional scraper and push plate conveying; choose FVC hollow pin type for bucket and cross-bar assembly scenarios.

• Track Adaptation: FVT large roller type is prioritized for rail-guided conveying to reduce chain plate friction loss.

• Environmental Adaptation: Enhanced hardening treatment for dusty and abrasive working conditions; stainless steel SSFV type for humid and corrosive environments.

5. Sprocket Matching & Daily Maintenance

• Sprocket Configuration: Matched with special FV series conveyor sprockets. Low tooth count design is commonly used for heavy-load conditions, and large-pitch sprockets adopt integral forging or welded structure for high strength.

• Lubrication Scheme: Grease lubrication is recommended for dusty environments. Dry grinding operation without lubrication is common for buried scraper conveyors, which requires enhanced surface hardening of the chain.

• Wear Monitoring & Replacement: Focus on the wear elongation of pins and sleeves. The chain should be replaced in time when the elongation rate exceeds 3% to avoid tooth jumping and equipment failure.

6. Product Comparative Advantages

• FV vs M Series Chain: Both are DIN European standards. FV series features larger pitch, higher strength and richer accessory options, making it the preferred choice for European heavy-load customers; M series is lighter and suitable for medium and light-load conveying.

• FV vs Double Pitch Conveyor Chain: FV chain has higher load-bearing capacity and better impact resistance, which is dedicated to heavy-duty scraper and buried scraper conveying; double pitch chains are mostly used for light-load packaging and automated production lines.
