Guide and guards ensures that rolled piece is correctly into and out of roll pass, to reach the device be rolled by required deformation condition.Whether relation is very large for the whether reasonable smooth rolling to rolled piece of guide and guards, directly affects the quality of product and the production capacity of milling train; In rolling, because guide and guard can afford irregular stress, strong high temperature wear, impact etc., easily cause its serious wear, service life can not be guaranteed.
Suspended macrosopic technology: in milling train district, steel stub bar portion from last rolling mill out, needs guide groove to guide, a rolling mill after entering.Between two rolling mills during continuous steel excessively, if guide groove inner chamber is suitably large, steel material can not contact with guide groove, airborne, and this is called suspension steel rolling state.Due to gravity, steel material sinks, or due to a rear rolling mill speed comparatively slow, steel material will play cover, and steel material probably contacts with guide groove; Arrange deflector roll in contact position, steel material becomes rolling friction in the friction of contact position from sliding friction.Now resistance is much little, and steel material surface also can not scratch.Steel material is kept off by one or many places deflector roll holder or helps, and does not contact, be also called suspension steel rolling state with guide groove.This state is that macroscopic view is visible, is suspended macrosopic technology.
Microcosmic suspension technology: Gang Liaochu milling train district, in the sky section of mistake of long distance, slow cooling section and water-cooled section, steel material inevitably with guide groove contact friction.Carry out special surface treatment to guide groove inwall, steel material and guide groove contact position have air film or moisture film to exist, and reduce frictional resistance, and prevent steel material from scratching.This is also considered to a kind of suspended state.This state is that microcosmic is sightless, is microcosmic suspension technology.To the deflector roll in milling train district, also carry out special surface process, namely guide roller surface also adopts microcosmic suspension technology, enhances anti-scratch effect.
But the utilization that above technology is not also become reconciled combines, and is therefore badly in need of above-mentioned Technology application to actual production.
