1.1450mm four roll tension leveller is designed to improve the surface quality, mechanical properties, improve product quality grade of cold rolled (P / C, stainless steel). The production and operation cost of this flat machine is low, the investment is low, the technology economy is high, and the best economic benefit is obtained.
The flat machine has the following characteristics:
So the pressure control using AFC, APC and other conventional settings, but also joined the AEC means.
2."S" - before and after the roller adopts vertical configuration, shorten the length of unit, equipped with auxiliary wear mechanism, improve the efficiency and safety of. The "S" roller can be used as a horizontal configuration according to the requirements.
And after the roll configuration, eliminate shape defects of ultra thin flat when the.
- rolling line adjusting device of the stepped wedge portfolio adjustment, the input of the diameter of the roller can be fast automatic control cylinder driving stepped wedge displacement to the right position, realize the automatic and fast adjustment of rolling line;
3.So the pressure plate correction and work roll bending shape control method can better control the finished strip.
Using double - roll changing car, work roll quick changing. Or the use of the lift type for the roller, save the unit area.
The - mill of Siemens S7-400 series programmable controller products, DC drive using 6RA70 series of full digital speed control system.
An uncoiling machine, roll machine, flat machine etc. Heavy load driving device gear speed reducer with six levels of precision alloy steel after carburizing and quenching gear, oil circulation lubrication. Key components such as the main shaft, the fan plate, the hollow shaft and so on.
So the roller polishing device can automatically polishing on the roll surface, improve the quality of products.
4.And key components of the imported products, such as MOOG servo valve, Sony magnetic scale, and can also be configured according to user requirements.
Using - direct hydraulic pressure and full function automatically extended rate control system and the high precision of constant tension control, to ensure high speed rolling sheet continuous belt, all main drive have adopted the low inertia motor configuration and high precision tension control, the control plate shape formation of thin gauge plate to provide a guarantee.
- in order to ensure the efficient use of, the design unit with rapid wear, quick roll change, and other functions, to ensure that the low labor intensity and high production efficiency.
5.And transmission and basic automation, AEC system with international famous manufacturer and the strongest domestic manufacturer supporting, critical bearing were
excellent. All the important transmission for high precision carburized gear tooth grinding.
