Maintenance for productivity Rolling models

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.

Roughing Mill - an overview | ScienceDirect Topics

Roughing mill: Precise control of roll gaps enables better stock control in each pass and avoids excess loading on mill rolls and drive systems owing to improper roll gaps. Faster and precision gap setting increases mill output. • Crop shear: Precise crop length reduces waste of rolling stock. This avoids mis-rolls in finishing mills. •

Introduction to rubber processing and safety issues

This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of

Study Provides Insights on Optimizing Roller Compaction ...

Phase 2 — Investigating correlations between granule properties and roll gap. Two sets of discrete tests were carried out with a fixed roller speed and a constant compaction force while roll gap increased from 1.5 to 5 mm. The first, with six batches, used a compaction force of 4.5 kN/cm and the second, with three batches, used 9 kN/cm.

Automatic Gauge Control (AGC)/ Hydraulic Gap Control (HGC)

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.

US3662576A - Control for roll gap of a rolling mill ...

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.

Automatic Gauge Control in Rolling Process Based on ...

Meanwhile, it is also a typical complex electromechanical system; distributed control has become the mainstream of computer control system for rolling mill. Generally, the control system adopts the 2-level control structure—basic automation (Level 1) and process control (Level 2)—to achieve the automatic gauge control.

Roller Mill Maintenance00 - CPM

Roller mills are also more sensitive to instantaneous changes in the feed rate than are other pieces of process equipment. Feeding a roller mill directly from a screw conveyor or bucket elevator will cause surges in the feed rate that the roller mill "sees" instantaneously unless some damping system such as a surge hopper is used.
