Abstract
A kind of heater for rolling steel cantilever roll sleeve, ontology is covered including roller, one end that roller covers ontology is ring flange, the other end is cantilever end, it is characterized in that, it is provided with equally distributed 6-8 items axial direction external extension seam on the ring flange of roller set ontology, is provided with the equally distributed inside expansion joint of 4-6 axis on the cantilever end inner wall of roller set ontology, external extension seam is parallel with interior expansion joint.The heater for rolling steel cantilever roll sleeve of the present invention, since axial external extension seam is provided on the ring flange that roller covers ontology respectively, it is provided with inside expansion joint on the cantilever end inner wall of roller set ontology, so that overhang roll roller is sleeved on by high temperature and when expanding with heat and contract with cold of low temperature period, external extension seam, interior expansion joint have buffered the stress that expands with heat and contract with cold that roller set ontology generates significantly, the crack for avoiding roller set ontology generates, to improve the service life that roller covers ontology.
Description
Technical field
The present invention relates to heater for rolling steel, especially a kind of heater for rolling steel cantilever roll sleeve.
Background technology
Heater for rolling steel overhang roll roller covers in use, when heater for rolling steel production, stop production between will produce high temperature, low
The warm period, expanding with heat and contract with cold can cause overhang roll roller set crack occur, influence the service life of equipment.
Invention content
It is an object of the invention to provide a kind of heater for rolling steel cantilever roll sleeves simple in structure, with long service life.
The heater for rolling steel cantilever roll sleeve of the present invention, including roller cover ontology, and one end that roller covers ontology is ring flange, another
End is cantilever end, which is characterized in that equally distributed 6-8 items axial direction external extension seam, roller set are provided on the ring flange of roller set ontology
The equally distributed inside expansion joint of 4-6 axis is provided on the cantilever end inner wall of ontology, external extension seam is parallel with interior expansion joint.
The heater for rolling steel cantilever roll sleeve of the present invention, it is axial overhanging due to being provided on the ring flange that roller covers ontology respectively
Contracting is stitched, and is provided with inside expansion joint on the cantilever end inner wall of roller set ontology so that overhang roll roller is sleeved on by high temperature and low temperature time
When expanding with heat and contract with cold of section, external extension seam, interior expansion joint have buffered the stress that expands with heat and contract with cold that roller set ontology generates, have avoided roller significantly
The crack for covering ontology generates, to improve the service life that roller covers ontology.
