Reducing and Sizing Mill
The Reducing and Sizing Mill (RSM) is positioned between the finishing block mill and the high-speed laying head.
Designed with a split structure and independent twin-module block transmissions, it ensures flexibility and ease of production and maintenance.
This advanced configuration significantly enhances the internal structure and surface quality of the final product.

Application
Differences Between
RSM and Conventional Block Mill
• For RSM, The rolling force (KN) will be higher than finishing blocks.
• More flexible than finishing blocks
• Lower prices for spare partsLower power for each RSM`s motor(Low voltage motors can be used)&Lower Electrical Investment
• Lower transmission energy consumption and no-load power
• The bypassing RSM can be stopped to reduce energy consumption and save energy
• When an RSM fails or undergoes maintenance, it can be bypassed or directly replaced with a new block
• Lower prices for spare parts
Outstanding Structure of RSM
• The new high-speed RSM employs dual lubrication systems for the bevel gearbox and roll box, ensuring more thorough equipment lubrication while increasing the number of return oil holes. This effectively eliminates machine burning caused by inadequate lubrication and prevents equipment oil leakage due to enhanced oil pressure and poor return oil flow.
• The cooling water pipes of the high-speed RSM are made of aluminum alloy and designed with a “Snap-On” mechanism, facilitating installation and maintenance. This design allows for easy removal of impurities and blockages in the water circuit and enables swift handling of steel pile-ups.
• The panel thickness of the roll box in the high-speed RSM is 110mm (contrasted with 80mm thickness in other enterprises), and it undergoes nickel-phosphorus alloy plating to prevent corrosion and calcification caused by local water quality. This enhances rolling rigidity and hardness while reducing spare parts wear.
• The bevel gearbox of the high-speed wire rod reducing sizing mill employs a “double long shaft” design for greater stability of the bottom support. The input shaft diameter is increased to ∮145mm (compared to 100mm in other enterprises), enhancing rolling force. Additionally, separate lubrication for gears reduces the incidence of accidents and saves production costs.
• The high-speed RSM adopts a single pass type, facilitating continuous rolling with the preceding finishing block mill and enabling low-temperature rolling.
