STAND MILL

SSEC manufactures reliable mill stands with rigid structures and quick roll change capabilities. These stands produce various types of bars, wire rods, angles, channels, and universal beams. The conventional mill stands consist of housing and cap assemblies, with rolls rotating in fiber/anti friction bearings and chocks. They are powered by electric motors and have a balanced housing design for minimal deflection under rolling loads.

STAND MILL
Housingless

4Hi Stand

The mill as the name suggests consists of two back up rolls and two work rolls housed in the same housing. These are very much in vogue for the flat and strip mills. The work rolls bite the material and the rolling load is transferred to the larger back up rolls with high capacity bearings. The work rolls being small in diameter have small area of compression and hence the rolling load is less. However here the bite angle limitations have to be seen otherwise the material may start slipping and may not enter the roll bite.

Housingless

Housingless mill stands are designed without housings and caps, with chocks connected through four housing screws with worm wheels for roll gap adjustment. This feature enhances bearing life and reduces product size deviations over stock length. Combining horizontal and vertical housingless stands ensures sequential pass reduction without twisting the material, reducing mill cobble. The stands also feature axial movement for fixed pass lines.

4Hi Stand

Pre-Stress Stand

The mill consists of Conventional mill stands but the mill is pre-stressed with the help of hydraulic four nuts that pre-stresses the system such that the mill is preloaded to the maximum roll separating force during rolling time. When the stock passes under the rolls there is practically no further deflection of the mill stand under rolling load.

Convertible Stand

The cantilever stands are basically designed like a block mill and can be configured horizontal or vertical as per design requirement. The rolls are mounted on sleeve bearings so that high mill speeds can be achieved to produced wire rod 5.5mm to 8mm.
