Round Link Chain and Connectors for SSC Systems
Round Link Chains for Slag Removal Conveyors in Thermal Power Plants Round link chains for slag removal conveyors in thermal power plants represent a highly specialised niche within bulk material handling, yet they operate under arguably the most punishing conditions of...Read more -
Choosing the Right Surface Finish for Steel Wire Rope: A Practical Guide
Choosing the Right Surface Finish for Steel Wire Rope: A Practical Guide When a client inquires about steel wire rope or slings, the surface finish is often left unspecified — or the client may simply not know which option is best. Yet the finish directly determines cor...Read more -
TO EXPLORE THE OPPORTUNITIES IN BIDDING ON LONGWALL MINING CHAINS TENDER
Longwall mining chain procurement is fundamentally different from general industrial chain sales: the purchaser’s primary decision metric is “coal tonnage produced before chain replacement”, not the chain’s nominal breaking force. This section examines that relationship ...Read more -
Lifting Chain Hardness vs. Strength: A Metallurgical Guide to G80 and G100 Quality Verification
In the lifting chain industry, the overwhelming majority of end users evaluate quality through a single lens: minimum breaking force. A chain that passes the 4:1 safety factor test is deemed acceptable, and the conversation ends there. This perspective, while understanda...Read more -
CASE HARDENED ROUND LINK CHAIN HARDENSS TESTING GUIDE
(This guide provides a detailed, engineering-focused procedure for preparing hardness test specimens and conducting Vickers hardness testing on carburized round link chains used in bulk material handling applications such as cement plant bucket elevators and power plant ...Read more -
A Comprehensive Introduction to Round Link Chain Sprockets
Round link chain sprockets, also widely referred to as chain wheels, are indispensable mechanical components in a vast array of heavy-duty industrial applications and materials handling. Their primary function is to engage precisely with round link chains to transmit mot...Read more -
SCIC’s Quality Control Excellence in Pump Lifting Chain Manufacturing
The retrieval of submersible pumps from seawater or brackish water environments is a high-stakes operation. A failed lifting chain means not only the loss of a very costly pump but also significant safety risks and operational downtime. At SCIC (www.scic-chain.com), we u...Read more -
Longwall Mining Chains Surface Finish/Coating Review
For longwall mining chains operating underground, corrosion is a persistent threat that works in concert with fatigue and abrasion to shorten service life. Surface finishes are the primary defense against this, but each option represents a compromise between corrosion pr...Read more -
EN818-7 Fine Tolerance Hoist Chains: Engineering Demands and Manufacturing Challenges for Types T, DAT, and DT
EN818-7 is the European standard that specifies safety requirements for fine tolerance hoist chains, Grade T, intended for use in serial chain hoists—both manual and power driven. Unlike general-purpose lifting chains covered under EN818-2 (which are medium-tolerance cha...Read more -
Steel Materials Consideration for Longwall Mining Chains
Longwall mining chains are among the most critical yet cost-intensive consumable components in underground coal extraction. As a result, many overseas clients — particularly for smaller chain sizes such as 14×50 mm, 18×64 mm, 19×64 mm, and 22×86 mm — are actively explori...Read more -
