Description

High life molybdenum filament stove boiler tube
Technical Field
The utility model relates to a high life molybdenum filament stove boiler tube.
Background
The service life of the furnace tube of the molybdenum wire furnace is generally only one year, after long-term high-temperature sintering, the furnace tube is easy to deform and collapse, the sintering boat is blocked, the boat is pushed unsmoothly, the product quality is influenced, in addition, the production progress is influenced by re-bricking, and the cost is very low. The traditional furnace building mode is that a heat preservation ball is padded under a furnace tube, and under the production condition of long-term high temperature, the heat preservation ball is easy to soften and collapse, and the furnace tube is lack of support, so that the furnace tube deforms, collapses, cracks and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high life molybdenum filament stove boiler tube can effectively solve the yielding problem of collapsing of traditional molybdenum filament stove boiler tube.
In order to solve the technical problem, the utility model discloses a realize through following technical scheme: a furnace tube of a high-service-life molybdenum wire furnace comprises a furnace tube body, wherein a plurality of corundum plate cross beams are arranged on the outer side surface of the bottom of the furnace tube body.
Preferably, the cross section of the corundum plate cross beam is rectangular, the contact surface of the corundum plate cross beam and the furnace tube body is increased, and the corundum plate cross beam with the rectangular dream section has a good supporting effect on the furnace tube body.
Preferably, the distances between the adjacent corundum plate cross beams are equal, so that the uniform supporting force of the corundum plate cross beams on the furnace tube body is ensured, and the furnace tube body is prevented from being broken due to uneven stress.
Preferably, every corundum plate crossbeam all sets up along boiler tube body width direction, and transverse arrangement is simple and easy, the operation of being convenient for.
Preferably, the length of the corundum plate cross beam is equal to the width of the furnace tube body, and a good supporting effect is achieved on the whole transverse direction of the furnace tube body.
Preferably, the included angle between the length direction of the corundum plate cross beam and the length direction of the furnace tube body is an acute angle, and the corundum plate cross beam is supported in an inclined mode, so that the contact surface of the corundum plate cross beam and the furnace tube body is enlarged as much as possible.
Preferably, the outer side surface of the bottom of the furnace tube body is a plane, and is more fully contacted with the corundum plate cross beam.
Compared with the prior art, the utility model has the advantages that: the corundum plate cross beam is additionally arranged at the bottom of the furnace tube body, so that the corundum plate cross beam has good heat resistance even if softening and collapse are required by heat preservation under the condition of long-term high temperature, the furnace tube body can be supported well, the furnace tube body is prevented from collapsing, deforming and cracking, and the service life of the furnace tube body is prolonged.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1 to 3, in order to illustrate one embodiment of a furnace tube of a molybdenum wire furnace with a long service life of the present invention, the furnace tube of the molybdenum wire furnace with a long service life includes a furnace tube body 1, and a plurality of corundum plate beams 2 are disposed on the outer side surface of the bottom of the furnace tube body 1.
By additionally arranging the corundum plate cross beam 2 at the bottom of the furnace tube body 1, under the condition of long-term high temperature, even if softening and collapse are required by heat preservation, the corundum plate cross beam 2 has good heat resistance, and can also well support the furnace tube body 1, so that the furnace tube body 1 is ensured not to collapse, deform and crack, and the service life of the furnace tube body 1 is prolonged.
Specifically, the cross section of the general corundum plate beam 2 is rectangular, so that the corundum plate beam has good bearing capacity, and certainly, the cross section can also be in a semi-circular arc shape or other geometric shapes, but the surface contacting with the bottom of the furnace tube body 1 is a plane, and meanwhile, the outer side surface of the bottom of the furnace tube body 1 is a plane.
And adjacent corundum plate cross beams 2 are uniformly distributed, and are generally distributed in parallel and at equal intervals, so that the stress conditions of the furnace tube bodies 1 at different positions are easier to calculate compared with random distribution, the using amount of the corundum plate cross beams 2 is reduced, and the corundum plate cross beams 2 are preferably arranged along the width direction of the furnace tube bodies 1 and are convenient to process and set. And the length of the general corundum plate beam 2 is equal to the width of the furnace tube body 1, and the whole furnace tube body 1 is transversely supported.
When in use, the corundum plate cross beams 2 are directly paved on the heat preservation balls below the furnace tube body 1, or the heat preservation balls are filled between the corundum plate cross beams 2, and then the corundum plate heat preservation furnace tube can be used normally. The corundum plate cross beam 2 plays a good role in supporting the furnace tube, and the problems that the furnace tube is easy to deform, collapse and the like are avoided under the production condition of long-term high-temperature sintering.
Example two:
as shown in fig. 4, the difference from the first embodiment is that: the corundum plate cross beams 2 are arranged in different modes, and the included angle between the length direction of the corundum plate cross beams 2 and the length direction of the furnace tube body 1 is an acute angle, but the included angle is not too small and is near 90 degrees as much as possible, so that the corundum plate cross beams 2 are too long, and the cost is increased too much.
The above description is only for the specific embodiment of the present invention, but the technical features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
