Description
Technical field
The present invention relates to iron and steel metallurgical industry continuous-casting of steel billet technical field, particularly a kind of fan-shaped sections of slab continuous roll gap
Adjusting apparatus.
Background technology
Slab caster uses straight arc type mostly at present, and it is generally close using small roller diameter that it casts the design of stream guidance system
The roller row arrangement of roller is arranged, strand is clamped by interior outer arc roller, and interior outer arc roller opening degree, that is, roll gap is typically designed as along casting
Flow the contraction roll gap in direction.Slab caster soft reduction technique develops on the basis of roll gap technology is shunk, static
Slighter compress is the pre-set roll gap before casting, which is the solidification shrinkage property settings according to steel, is had necessarily
Taper, a kind of method then cast according to the pulling rate and process conditions of setting, and dynamic soft-reduction is in casting cycle
In the middle as the change in location of Coagulated hemothorax adjusts roll gap and a kind of casting method of roll gap shrinkage degree.
Roll gap, the sector of dynamic soft-reduction can remotely be adjusted certainly by being capable of the slab caster of dynamic soft-reduction its fan-shaped section
Section almost all is hydraulic clip compact form.It is to realize the pass of dynamic soft reduction technology that hydraulic clip compact form, which remotely adjusts the fan-shaped section of roll gap,
Button apparatus, can rapidly adjust the shrinkage degree of roll gap and roll gap at a distance in the main operation room of conticaster, improve conticaster
Operating rate.
Larger casting blank deformation drag, slab caster during due to needing to bear larger ferrostatic pressure and slighter compress
Often design strength is larger for segment roll gap adjusting apparatus, and hydraulic cylinder cylinder diameter is accordingly also larger, it is crucial be used to connect it is inside and outside
The pull rod or pulling plate shape of arc frame are thick, the fixed pin or nut of its end are then subjected to the load for being equal to hydraulic cylinder, Gu
The diameter or screw thread specification of rationed marketing or nut are much bigger with screw thread compared to conventional pin, this has resulted in whole roll-separating mechanism and has existed
It is inconvenient in terms of dismounting.In addition, slab fan-shaped section roller is worn quickly in hot environment, even if using water cooled rolls design simultaneously
And also do not grown in roll surface built-up welding stainless steel, its service life, outer arc roller need to be overhauled often and again to arc in fan-shaped section, in fan-shaped section
Outer arc frame need to be opened often, and roll-separating mechanism must just be dismounted with arc frame inside and outside zoarium by separating, therefore roll gap adjusts
The property easy to assemble of device is to influence the key of fan-shaped section maintenance workload.
