Description
Technical field
The utility model is related to Equipment for Heating Processing, more particularly to a kind of heat-treatment furnace hearth roll.
Background technology
The steel bar plate that hearth roll is heat-treated in solution heat treatment furnace for transmission, to realize continuous heat
Technical process, high temperature section hearth roll is made in 1000~1200 DEG C of temperature ranges and under the oxidative environment of open firing
Industry, these hearth rolls must be able to be kept in long time continuous working the ability of transmission high temperature slab.Under high temperature oxidation stability environment
Operation, roller surface is easily damaged, it is necessary to which pair roller barrel can just be reused after carrying out turning, grinding, this occupation mode
Both the production efficiency of steel mill had been influenceed, and has caused hearth roll service life short because frequently machining.Chinese patent notification number
In " a kind of hearth roll " of CN202836219U, fixed cover, roll shaft, pottery are provided with roll shaft, positioned at ceramics or carbon roller set two ends
Porcelain or carbon roller set and fixed cover are connected as one by trundle.Although this structure can realize the replacing of roller, roll shaft,
Changing every time need to dismount trundle, and time-consuming bothersome, efficiency is low.
The content of the invention
The utility model is in view of the shortcomings of the prior art, there is provided a kind of anti-oxidant hearth roll that can be convenient for changing roller.
The utility model is achieved through the following technical solutions technical goal.
Anti-oxidant hearth roll, including roller, roll shaft；The roller is sleeved on roll shaft；The roller includes alloy sheath, gold
Category ceramic jacket, cermet set is sleeved on alloy sheath；It is theed improvement is that：The roller endoporus is matched somebody with somebody with roll shaft outer wall gap
Close；The roll shaft shaft end at the roller two ends is respectively equipped with fastening structure, and roller is fixedly connected on roll shaft.
In said structure, the fastening structure includes clamp nut, spacer, and clamp nut, spacer are sleeved on roll shaft shaft end,
Spacer is arranged between roller, clamp nut, and clamp nut is threadedly coupled with roll shaft shaft end.
In said structure, the spacer is provided with seam, and the cermet set termination is located in spacer seam.
In said structure, key is provided between the roller, roll shaft, roll shaft drives roller by key.
The utility model compared with prior art, has the positive effect that：
1st, roller endoporus and roll shaft outer wall gap coordinate, and the roll shaft shaft end at roller two ends is respectively equipped with fastening structure, by roller
Cylinder is fixedly connected on roll shaft, so can conveniently and efficiently change roller, when roller is damaged serious, can rapidly by roller from roller
Changed on axle, new roller is changed, significantly improve steel mill's production efficiency, significantly extension hearth roll service life.
2nd, fastening structure fastens roller using nut, is easy to fastening.
3rd, roller outer layer is provided with cermet set, and high temperature resistant, thermal expansion is small, and chemical stability is good, has stable high-temperature performance, defeated
Send quality high.
4th, spacer is provided with seam, and cermet set termination is located in spacer seam, can effectively prevent cermet set
Termination is damaged.
5th, key is provided between roller, roll shaft, roll shaft drives roller by key, realizes being driven by key, the fastening of roller two ends
Structure is without applying too noticeable effort.
