The reducing and sizing mill(RSM) is arranged between the finishing blocks and high speed pinch roll & laying head.
It adopts split structure and independent transmission which makes it easy to manufacture and maintain. It also improves the internal structure and surface quality of the finished product, and has the advantages of high-speed and controlled rolling and quick change of TC rolls.

• 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
• 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.

Composite wire rod & rebar production line uses φ285 and φ230 mono block rolling mill group without twisting. The rolling mill machine can be horizontal mill, vertical mill and the top cross type with tungsten carbide roll ring.
Composite wire rod & rebar production line is mainly customized for small and medium plants, because their required annual capacity is about 300, 000 tons - 500, 000 tons, fully in consideration of the investment capacity of the steel company, the size of the plant scale and other conditions.
For the new production lines, one production line of investment is available to achieve the output of high-speed wire rod and rebar. Composite wire rod & rebar production line can help steel plant avoid duplication of investment, ensuring the equipment operating rate.
For old retrofit line, we can make full use of existing equipment and space, with a small investment producing the original single varieties developed into a variety of specifications of products, making economic benefits increasing doubly.
Composite high-speed wire rod & rebar production line adopted low-power, high-speed design, process arrangement. Compared with traditional two lines, it can reduce the energy consumption of 1/3 to 2/5.
A composite high speed wire rod & rebar production line can roll out of a variety of specifications of wire rod and rebar products:
Small diameter of steel bar: φ8/φ10/φ12/φ14/φ16
Large diameter of round bar and deformed steel bar: φ18-φ32
Wire rod specification: φ5.5/φ6.5/φ8/φ10/φ12/φ14/φ16
Composite high speed wire rod & rebar production line adoped quick-change , fast transfer design, easy replacement of product variety, fast, reliable, simple and easy to master.
Steel enterprises can flexibly adjust product specifications according to market demand, maket in control!
