Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The present embodiment is related to a kind of furnace roller, is installed on the furnace wall of heating furnace, is used for transporting steel billet.One kind of the furnace roller is shown
Example property structure is as shown in Figure 1 comprising rotation is set on furnace wall and in the furnace roller body 2 with edge axially through cavity, fixed
It is sleeved on the body of roll 1 at 2 middle part of furnace roller body, and to constitute to the cold of the cooling of furnace roller body 2 in 2 cavity of furnace roller body
But device.
In the above structure, furnace roller body 2 is mounted on the furnace wall of heating furnace by the two high temperature resistant bearings 5 of suit on it
On, in order to improve the using effect of furnace roller, in the present embodiment, furnace roller body 2 is made of 1Cr18Ni9Ti stainless steel material.
In the present embodiment, in order to improve the heat insulation of furnace roller body 2 Yu 1 junction of the body of roll, distinguish at 1 both ends of the body of roll
Sunken inside is formed with recessed portion 101, and thermal insulation material is filled in each recessed portion 101, and pass through respectively at the both ends of the body of roll 1
High-temperature agglomerant is fixed with heat insulation loop 8, to prevent thermal insulation material from loosely falling, and is respectively welded admittedly in the outside of each heat insulation loop 8
It is connected with baffle 4.In the present embodiment, thermal insulation material is preferably alumina silicate fibre, alumina silicate fibre light, high temperature resistant, heat with bulk density
The advantages that stability is good, and pyroconductivity is low, good flowing properties, is conducive to the filling in recessed portion 101.
In addition, since the middle part of the body of roll 1 is contacted with steel billet and furnace roller body 2 respectively, the especially periphery wall and steel of the body of roll 1
It during base contacts, is often worn out and hits, therefore, the body of roll 1 in the present embodiment uses high temperature heat-resisting steel
Cr28Ni48W5 material is made, and can use in 1200 DEG C or more of environment for a long time, but since its density is big, roller
The length of body 1 should shorten as far as possible on the basis of guaranteeing steel billet transmission.
In the present embodiment, since furnace roller works under high temperature environment, the cracking being keyed in order to prevent, in furnace roller body 2
Periphery wall on be formed with limited step 201, the bottom of one recessed portion 101 can be connected to limited step 201, and weld and be connected
Onto furnace roller body 2.As furnace roller body 2 and the difference of material used by the body of roll 1, corresponding high-temperature expansion coefficient is also different,

Insulating layer 3, to the further thermal insulation protection of furnace roller body 2.The lightening casting material high fluidity and high-strength characteristic, due to pouring
Narrow space is built, vibrating head is not easy to be inserted into, when carrying out lightening casting material casting, it is only necessary to which slightly being shaken with vibrating head can be complete
At casting, without pouring defects such as hole, groove, voids and pits.
Since furnace roller will not only bear the impact and vibration of steel billet in the process of running, and the hull-skin temperature of furnace roller is long-term
In 1200 DEG C, the temperature in 2 axle center of furnace roller body but only has 40-50 DEG C, and lightening casting material inside and outside has very big temperature ladder
Degree.Therefore, high efficiency composition additive and Ultramicro-powder are added in the present embodiment, in lightening casting material to guarantee environment temperature 1200
DEG C, under the premise of hot modulus of rupture 7MPa, furnace roller is obtained into general equilibrium from room temperature to the intensity of 1200 DEG C of each temperature sections
Promotion.
Meanwhile suitable steel fibre is added in lightening casting material, can have as the flexible substrate in lightening casting material
Effect reduces the appearance in crack, and prevents the extension in crack.In conjunction with Fig. 2, circumferentially-spaced in furnace roller body 2 is equipped with multiple fixations
The anchoring piece 10 of insulating layer 3, and each anchoring piece 10 also have along 3 length direction of insulating layer extension, with to insulating layer 3 comprehensively into
Row is fixed, and baffle 4 has been respectively fixedly connected in the both ends of insulating layer 3, to prevent the lightweight pouring material at both ends loose.
Furnace roller described in the utility model can be to furnace by filling thermal insulation material in the recessed portion 101 at 1 both ends of the body of roll
Roller body 2 is thermally shielded protection；And by setting insulating layer 3, protection further is thermally shielded to furnace roller body 2, to mention
The heat insulation and structural strength of high furnace roller.
