Abstract
The invention discloses a furnace bottom roller for a heat treatment furnace. The furnace bottom roller comprises a roller drum, a roller shaft and end covers. The roller shaft is arranged on the axis of the roller drum. Supports are arranged in the radial direction of the roller shaft, and the other ends of the supports abut against the inner wall of the roller drum. Axial through roles are formed in the wall of the roller drum. The end covers are connected with the two ends of the roller drum in a sealed manner and internally provided with radial through roles communicated with the axial through holes. The axes of the two ends of the roller shaft are of blind-hole structures, and cooling water through holes communicated with the radial through roles are formed in the positions, connected with the end covers, of the roller shaft. According to the furnace bottom roller, cooling water is injected through the roller shaft and flows through the end covers to reach the roller drum, so that the temperature of the whole furnace bottom roller is reduced. In addition, heat insulation mats are arranged on the supports between the roller drum and the roller shaft, so that the performance of the whole product is improved, the heat dissipation effect is good, and the service life of the roller shaft is long.
Description
Technical field
The present invention relates to technical field of heat treatment equipment, especially a kind of heat treatment furnace furnace bottom roll.
Background technology
Furnace bottom roll is located at for transmitting the steel bar plate of heat-treating in solution heat treatment furnace, to realize continuous heat treatment technological process; High temperature section in this process, furnace bottom roll is in 1000 ~ 1200 DEG C of temperature ranges and operation under the oxidative environment of open firing, and these furnace bottom rolls must keep the ability of transmission high temperature slab in long time continuous working.The furnace bottom roll of prior art comprises roll shaft, roller, end cap, roll shaft is the elongated mandrel axially running through roller, and under high-temperature service environment, a large amount of heat of roller surface passes to roll shaft, although roll shaft inside is provided with axial cooling water hole, but cooling performance is limited, the heat suffered by roll shaft can not distribute in time, causes roll shaft to be out of shape, furnace bottom roll can be caused time serious to lose efficacy, work-ing life is short, and furnace bottom roll lost efficacy and just need to stop production replacing furnace bottom roll, reduced production operation efficiency.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of heat treatment furnace furnace bottom roll, structure is ingenious, good heat dissipation effect, long service life.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of heat treatment furnace furnace bottom roll, comprises roller, roll shaft and end cap, and roll shaft is located on the axis of roller, and roll shaft radial direction is provided with support, this support the other end is against roller inwall; The wall of roller is provided with axially extending bore; This end cap and roller two ends are tightly connected, and are provided with the radial direction through hole be communicated with axially extending bore in this end cap, and this axle center, roll shaft two ends is set to blind hole structure, is provided with end cap junction the water coolant through hole be communicated with radial direction through hole.
Further, this support is set to movable supporting, and the one end against roller inwall is provided with heat insulating mattress.
Compared with prior art, the present invention has the following advantages: adopt and inject water coolant through roll shaft, flow through end cap to roller, whole furnace bottom roll is lowered the temperature, support in addition between roller and roll shaft is provided with heat insulating mattress, whole product performance are got a promotion, good heat dissipation effect, roll shaft long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of heat treatment furnace furnace bottom roll of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of heat treatment furnace furnace bottom roll as shown in Figure 1, comprises roller 2, roll shaft 1 and end cap 3, and roll shaft 1 is located on the axis of roller 2, and roll shaft 1 radial direction is provided with support 4, and this support 4 the other end is against roller 2 inwall; The wall of roller 2 is provided with axially extending bore 21; This end cap 3 is tightly connected with roller 2 two ends, and be provided with the radial direction through hole 31 be communicated with axially extending bore 21 in this end cap 3, this axle center, roll shaft 1 two ends is set to blind hole structure 11, is provided with end cap junction the water coolant through hole be communicated with radial direction through hole 31.
This support 4 is set to movable supporting, and the one end against roller 2 inwall is provided with heat insulating mattress 5.
The present invention adopts and injects water coolant through roll shaft, and flow through end cap to roller, whole furnace bottom roll is lowered the temperature, and the support in addition between roller and roll shaft is provided with heat insulating mattress, whole product performance is got a promotion, good heat dissipation effect, roll shaft long service life.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
