Segmented cooling system

Segmented cooling system

Based on a large amount of design experience, the Roller Stage Cooling System developed by Aussie Aircraft provides precise zoned cooling control for the actual working conditions of the rolling mill to solve the problem of asymmetric hot deformation of the roll caused by uneven roll temperature. The shape of the product is guaranteed.

 Fully electromagnetically driven on-off valve

The fast response of the all-electromagnetically actuated on-off valve allows it to accurately implement the control signals given by the manual or control system; the wide flow range allows it to adapt to different flow requirements.

 Self-positioning fan nozzle

The fan nozzle has stable nozzle parameters and can be self-aligned to ensure that the nozzle does not change after the replacement or inspection; the parabolic water distribution ensures uniform distribution of the coolant and high thermal conductivity.

 Control Unit

The high-speed remote IO based on EtherCAT bus protocol is used to realize the switching control of the solenoid valve or the precise switching time ratio control, and ensure the synchronous operation of the solenoid valves at the corresponding positions of the upper and lower rollers, and finally realize the precise control of the temperature distribution of the rolls, and Ensure a good lubrication environment between the rolling stock and the roll; optional stand-alone display monitoring system, or display monitoring integrated in the display interface of the plate thickness / shape control system; optional independent display or operation Physical buttons can also be implemented using a software interface.

 System Features

Provide multiple forms of interface for external systems

Support various mainstream protocols:EtherCAT、 PROFIBUS、PROFINET、CANopen、 DeviceNet;

Widely adapt to external systems: seamless access to computer systems or PLC systems;

Two signal modes are available: duty cycle signal, switching signal;

Quick and easy installation and debugging

The fully electromagnetically actuated on-off valve eliminates the demanding requirements for compressed air;

The valve body can be removed from the front of the segmented cooling beam body for easy access and maintenance;

Electrical and hydraulic piping is simple and comes with a protective cover to avoid extensive exposure;

Provide a clean and efficient working environment for production

The dense sealing and internal micro-positive working environment keeps the segmented cooling beam body fresh and does not pollute the internal components;

The understanding of the fluid characteristics and the selection of the jet flow rate and angle can better exert the process effect and facilitate the production of a cleaner surface strip;

Pressure and temperature monitoring capability

The system is equipped with temperature and pressure sensors to monitor the pressure in the spray beam and the temperature of the coolant in real time;

Excellent control algorithm ensures that the internal pressure of the spray beam is stable during operation, avoiding the water hammer phenomenon of the coolant when the control valve is opened and closed;

 The main function

Improve shape and extend roll life

Precise cooling releases the internal stresses in the rolls and adjusts the temperature profile, which improves the roll shape, ensures product flatness and extends roll life.

Lubrication to improve the surface quality of the strip

The exact coolant flow ensures interfacial lubrication between the rolled material and the rolls, which increases the rolling speed and increases the reduction.

Accurate jet position and spray angle create good rolling conditions, reduce the formation of particulate matter on the surface of the rolled material, and improve the surface quality of the product.

Get maximum heat transfer and improve cooling efficiency

The optimal nozzle arrangement maximizes the heat of the rolls and increases cooling efficiency.

The valve body is made of high-quality stainless steel material, and the structure is designed by the principle of differential pressure. It is different from the pneumatic pilot valve. It has simple structure and is easy to clean and maintain. It is a normally closed valve in the state of power failure, which avoids the problem that the coolant cannot be closed in time when the rolling mill is on fire. The design of the large spout makes the solenoid valve form a stable laminar jet, which ensures the accuracy of the roll cooling; the contact type electrical interface can be quickly disassembled from the front end;
