Developments in mixing mill. Stock Blender: A main disadvantage in mixing on a two-roll mill is that the process is dependent on the operator skill. Stock blenders reduce this operator variable in the mixing process. Use of a stock blender improves mixing quality, reduces human interference and gives consistent productivity.
Once within specification, AGC optimises the mill speed by adjustment of tension, load or gap. At the end of the coil, Auto-Slowdown ensures the product remains in specification for as long as possible and brings the mill to a halt with minimum amount of material left on the coil drum.
The two backup-rolls reduce the bending deflection of the work-rolls. Additionally, the mills are equipped with devices for bending compensation like hydraulic bending systems and/or specifically shaped rolls (CVC-rolls). These measures shall ensure a plain roll …

If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the ...
A feedback control system for a gap between rolls in a mill includes a variable inductance with a core on one roll and an armature on the other roll. This inductance, as well as a reference inductance and two auxiliary inductances, are interconnected to establish AC biased bridge. The relative phase of the bridge diagonal voltage is used to control the gap width.
Our mills stand out because of their very compact and robust construction, conformity to all relevant EU standards and universal potential for automation. In addition, the roller quality can be selected to suit the existing requirements. For special applications, the HF MIXING GROUP offers newly developed, wear protected rolls for the mills.
1 INTRODUCTION. Roll wear reduction is an effective way to save production costs and increase the productivity of the hot strip rolling mill. 1, 2 The continuous variable crown (CVC) roll wear is a seriously concerned since this technology has been used widely. Using CVC technology, the variable roll gap crown can be obtained by the artful roll shifting mechanism. 3, 4 As an innovative ...
Sourcing Guide for Two Roll Mills: China manufacturing industries are full of strong and consistent exporters. We are here to bring together China factories that supply manufactur
change of the roll gap. Generally, the thickness of the rolled strip is determined by the gap between the two work rolls. The actual position control is then performed by the exact and fast-acting hydraulic adjustment system. For the entry and exit section of the two-mill stand configuration of Fig.
The effects of mill stretch, roll deflection and roll flattening are corrected in the gaugemeter loop. In the gaugemeter branch the loaded roll gap and thus the rolled product thickness are calculated on the basis of information from the gap control positions and roll forces. Roll de …
two roll mill gap automation. Normally, two rows of nozzles are used in one header. The row of nozzles directed to the roll gap is for the basic cooling and lubricating of the rolls. It can be adjusted from the centre outwards to match the strip width being rolled, and the flow rates used are approx. 20-30% of the header flow rate. The second ...
Achenbach strip rolling mills reliably produce best strip qualities even at maximum rolling speeds, maximum rolling widths and highest coil weights. Designed either as 6-high or 4-high rolling mills they are always tailored to the specific operation purpose. Special applications, e.g. as bright rolling mills, require the 2-high rolling mill design.
The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
The operator also benefits from a safe work environment. The Stock Blender is an add- on accessory mounted on top of an open two-roll mill. 13 It aids in rubber blending by pulling the mix compound from the front roll of the mill and guiding it to the …

Roll-gap model The roll-gap model is further differen-tiated into a model for reduction mills and for skin pass / temper mills / foil mills. For reductions of more than about five percent and a larger ratio be-tween the mean gauge und contact length, a roll-gap model based on the classical circular arc theory of Ford, Ellis and Bland is used.
