6.3.5 Large Bulk Handling Conveyor Chain (CT) Large conveyance: The steel industry, container conveyance Application Example Large Bulk Handling Conveyor Chain (CT) is used in the steel industry to convey hot steel coils (up to 700 ° C) as well as slabs or other heavy objects, such as containers. This chain is very strong. It can convey several coils, which can weigh up to 45 ton/coil. Construction and Features CT Chain is used in pairs, and heavy objects are conveyed directly on them. Standard large pitch chains do not have enough capacity to support the extremely heavy loads (the limiting factor is the roller). For that reason, special cylindrical bearing rollers have been developed. They combine a high allow- able load for the roller with low coefficient of friction. The coefficient of fric- tion is 0.03, which is one-third to one-fourth the coefficient of friction of standard large pitch conveyor chain in normal temperatures. Figure 6.20 and Table 6.4 show the structure, dimensions, and functions of this chain. A coil can be conveyed on its side or straight up. When the coil is on its side, you can use the chain as shown in Figure 6.20. Special attachments need to be used when conveying a coil straight up. Figure 6.21 shows examples of Large Bulk Handling Conveyor Chains with attachments for conveying round objects, and one for curved conveyance.
