Abstract
The utility model discloses a furnace roller provided with a novel structure and used for a billet conveying roller way in a metallurgical industrial furnace. The furnace roller comprises a roller body, shaft necks and a roller shaft; wherein the roller shaft is installed on the shaft necks, and two shaft necks are welded at the two ends of the roller body in a tight fit way instead of the original transition fit way. The deformation difference of the roller body and the roller neck at high temperature is made up by the shrink range of 0.10-0.12mm, the phenomenon that the welding seam is torn up slowly due to no deformation difference can be avoided, the service life of the furnace roller is improved, the times for furnace shutdown for overhaul and roller replacement in a steel plant is reduced, and the maintenance cost of the steel plant and the labor intensity of workers can be reduced.
Description
Technical field
The utility model relates to and transports the steel billet roller-way in a kind of metallurgical industrial furnace.
Background technology
At present, at home and abroad in the metallurgical industrial furnace, going into stove and coming out of the stove of blank generally all adopts roller-way to take on steel, steel billet is sent in the stove by the dress steel rider road in the stove, by step rate steel billet is delivered to from the charging end stepping in the stove of discharge end on the tapping roller-way, finish the heating process of steel billet simultaneously, then it is sent industrial furnace and be rolled by tapping roller-way in the stove.Furnace roller in the market is made up of the body of roll, roll neck and roll shaft, and described roll shaft is installed on the roll neck, and roll neck is welded on the two ends of the described body of roll.In order to guarantee the mechanical performance under the furnace roller hot conditions, what could guarantee equipment reaches product synergy.What therefore the body of roll of furnace roller and roll neck material used all is Langaloy, except the chemical composition and the mechanical performance of control material, in the manufacturing process of product, strict control has all been carried out in machining accuracy, welding procedure, detection etc.But in actual use, can find that the weld seam between the body of roll and roll neck lost efficacy, cracking phenomena is arranged, and quantity be more, the serious body of roll and roll neck break away from.Though the body of roll, roll neck, roll shaft etc. are all intact, only because of welding seam failure, whole furnace roller can't use, causes the huge waste of material, increased production cost.Simultaneously, strengthen the steel mill's shutdown maintenance and the roll change frequency, increase steel mill's maintenance cost and labor strength, influence ordinary production.
The utility model content
The purpose of this utility model is to provide a kind of furnace roller of new structure, changing the furnace roller roll neck into interference fit by original interference fits is welded on the body of roll, the body of roll and roll neck modified difference have at high temperature been remedied by the magnitude of interference, avoid slowly weld seam not being torn phenomenon, improved the service life of furnace roller because of what have that modified difference causes.
The technical solution of the utility model is achieved in that
A kind of new structure furnace roller is made up of the body of roll, axle journal and roll shaft, and described roll shaft is installed on the described roll neck, it is characterized in that: described two roll necks are welded on the two ends of the described body of roll respectively by interference fit.
The magnitude of interference of described interference fit is 0.10-0.12mm.
Described roll neck is provided with dividing plate, by described dividing plate heat-insulating filler is installed in described roll neck inside.
The utility model compared with prior art has following advantage:
Because of the roll neck position of furnace roller in furnace wall, and the body of roll directly is subjected to the heating of radiant tube or naked light, dilatancy can take the lead in.The heat that is subjected to of roll neck is from the heat conduction of the body of roll, and relative expansion will be a little later.So the magnitude of interference of 0.10-0.12mm has remedied this modified difference, avoided in original technology, slowly weld seam is not torn phenomenon because of what have that modified difference causes, improve the service life of furnace roller, reduced steel mill's shutdown maintenance and roll change number of times, reduced steel mill's maintenance cost and labor strength.
2. by described dividing plate heat-insulating filler is installed in described roll neck inside, has reduced the heat transfer speed of the body of roll, roll shaft can be worked in normal working environment, improved the service life of roll shaft.

The specific embodiment
As can be seen from Figure 1, a kind of new structure furnace roller, form by the body of roll 4, axle journal 2 and roll shaft 1, described roll shaft 1 is installed on the described roll neck 2, it is characterized in that: described two roll necks 2 are welded on the two ends of the described body of roll 4 respectively by interference fit, and the magnitude of interference of interference fit is 0.10-0.12mm.Described roll neck 2 is provided with dividing plate 5, by described dividing plate 5 heat-insulating filler 3 is installed in described roll neck 2 inside.
In the process of furnace roller, be pressed into and weld at first with the heating of body of roll matching part, and then with roll neck.
Claims (3)
