Abstract
The utility model discloses a heat resistant roll collar for cast steel plate (CSP) furnace rollers of a heating furnace used in a steel plate production process in a steel mill, which comprises a roll shaft. Four four-equal-piece roller collar split bodies are evenly distributed on the roll shaft so that processing strength of the roll collar is reduced. The thickness of rib plates of the roll collar split bodies ranges from 32mm to 38mm, anti-impact strength of the roll collar is improved, and service life is prolonged. The roll collar is made of Cr35Ni55W9AL2 materials, and abrasion resistance and high-temperature anti-oxidation susceptibility of the roll collar are improved, so that the roll collar cannot crack in a using process.
Description
Technical field
The utility model relates to a kind of steel mill and produces used process furnace CSP furnace roller in the steel plate process, relates in particular to the heat-resisting collars of CSP furnace roller.
Background technology
Heat-resisting collars is the accessory on the process furnace CSP furnace roller, and according to the applying working condition requirement, heat-resisting collars is must anti-1100-1250 ℃ indeformable, do not ftracture, and steel plate does not occur piling up when moving in the above.Material on the at present domestic CSP furnace roller adopts Cr28Ni48W5, and the collars structure is split type.Be generally six equal portions, piecemeal is welded on collars on the roll shaft during processing, and this collars high temperature oxidation, wearing and tearing can occur in the medium-term and long-term operating mode of process furnace, even cracking occurs, adopts the branch body structure of six equal portions to increase the difficulty of processing of collars greatly simultaneously.
The utility model content
The utility model purpose is to provide a kind of heat-resisting collars of novel texture, adopts the branch body structure of quarter, alleviates the processing intensity of collars, strengthens collars gusset thickness simultaneously, improves the resistance to impact shock and the work-ing life of collars.
The technical scheme of the utility model is achieved in that
Heat-resisting collars comprises roll shaft, it is characterized in that: the split of equally distributed four quarter collars is arranged on the said roll shaft.
The gusset thickness of said collars split is 32-38mm.
The utility model compared with prior art has following advantage:
1. collars is made up of the split of quarter collars, has alleviated the processing intensity of collars, and collars adopts the Cr35Ni55W9Al2 material, has improved the wear resisting property and the high-temperature oxidation resistance of collars, guarantees that collars does not in use ftracture.
2. strengthen collars gusset thickness, the resistance to impact shock and the work-ing life of improving collars.

Embodiment
As can be seen from Figure 1, heat-resisting collars comprises roll shaft 2, and equally distributed four quarter collars split 1 is arranged on the said roll shaft 2.Gusset 3 thickness of said collars split 1 are 32-38mm.
Collars adopts Cr35Ni55W9Al2 materials processed, and gusset 3 thickness are 32-38mm.The laggard column rule of collars roughing cuts into quarter; Be welded on the roll shaft 2 after the line cutting, the collars after the change can bear 1150-1350 ℃ of furnace temperature, high-temperature oxidation resistance and wear-resistant being improved; This collars impact resistance also is improved simultaneously, guarantees that collars does not in use ftracture.
Claims (2)
1. heat-resisting collars comprises roll shaft ⑵, it is characterized in that: equally distributed four quarter collars split ⑴ are arranged on the said roll shaft ⑵.
2. heat-resisting collars according to claim 1 is characterized in that: the gusset ⑶ thickness of said collars split ⑴ is 32-38mm.
