Detailed Product Description

Hot Rolling Machine High Stiffness Modified Short Stress Path Rolling Mill

Rod and wire mill stand core is mainly composed of roll gap adjustment device, roll roll system, pull rod assembly, mill stand, guide beam and so on. In order to prevent the axial movement of the roll, the upper and lower rollers are provided with devices to prevent the axial movement of the roll.

1. Roll gap adjustment device: it is composed of hydraulic motor, transmission shaft, worm gear pair and bevel gear pair on the transmission side and operation side.

2. Roll system: it is composed of roll, four rows of short cylindrical bearings, thrust bearings and axial adjusting devices.

3. Pull rod assembly: by the bearing seat, pull rod, middle support seat, etc.

4. Mill stand: welding parts, compact structure, high rigidity and strength.

5. Guide beam: a.fixed guide; b.Radial and axial adjustment function; c.Spray pipes for the upper and lower rollers of the guide beam

Feature:

No.	Name	Feature
1.	Screwdown Gear	Equipped with a large speed ratio artificial adjustment device, so that the adjustment is more labor-saving, easier
2.	Rolling Mill Stand	The improved frame and the new frame guide device are used together to make the mill more stable and more rigid.
3.	Roll System	With axial adjustment device; With axial positioning device, no axial movement;
4.	Pull Rod Assembly	The double nut structure of main nut and secondary nut is adopted to eliminate the thread gap between the pull rod and the main nut by the balance force produced by the balance piece (butterfly spring or damping body), so as to improve the rolling accuracy. With spherical cushion structure, the roller box can be adaptive in the rolling process of the rolling mill, so that the bearing force distribution is more uniform, and the bearing life can be significantly improved.
5.	New Frame Guide Device	The new frame type guide device has the function of clamping up and down, so that the guide is fixed more firmly; The rigid connection between the frame and the frame makes the mill body more reliable and more resistant to impact force; Due to the use of guide frame, reduce the frame constraint point, make the roll assembly and disassembly more convenient.
6.	Roll Change	It can realize fast roll change and greatly improve the operation rate of the rolling mill.

Mill Model	Roll Specification	Roll Neck	Max. Rolling Force
Ø900	Ø1100/Ø750*1200mm	Ø390	7000KN
Ø850	Ø860/Ø730*1100mm	Ø360	6000KN
Ø750	Ø770/Ø650*1000mm	Ø320	5000KN
Ø650	Ø700/Ø610*850mm	Ø300	4000KN
Ø550	Ø610/Ø520*760mm	Ø280	3000KN
Ø450	Ø490/Ø420*700mm	Ø240	2000KN
Ø350	Ø380/Ø330*650mm	Ø200	1000KN
Ø280	Ø320/Ø260*550mm	Ø180	600KN

Advantage:

1.	The high stiffness of the mill ensures the high precision of the product, and it is easy to realize negative deviation rolling.
2.	Can realize symmetrical adjustment. This is of great significance for stable operation, improving operation rate, saving time for maintenance and replacement of guide beam, reducing operation accidents, avoiding process accidents such as elbow, impact and roll wrapping, and improving guide service life.
3.	Because the rolling mill changes the transfer path of force, the concentrated load of the pressing screw is changed to the scattered load on both sides of the bearing seat, so that the bearing and bearing seat are under better stress, and the bearing life is more than 1.5 times higher than that of the ordinary rolling mill, so as to reduce the cost of the product.
4.	The roll system of this kind of rolling mill should be pre-installed and adjusted before roll change, and the new roll system can be changed about 10min after stopping. And the new roller is adjusted after rolling one or two steel can ensure that the product qualified. Therefore, this rolling mill has good pre-adjustment performance, fast roll change and high yield.
