Conventionally, when heat treating treated materials with a round cross section,
In the case where the material is heated while being transferred through the heating zone of the heat treatment furnace and then quenched, the material to be treated is rapidly cooled and quenched using a cold water shower. In the case of the walking beam method, the round material is fed horizontally and heated to raise the temperature.
Subsequently, during quenching, the material to be treated is put into a quenching tank from a heating zone, or during tempering or annealing, it is slowly cooled to heat-treat the material depending on the purpose.

In the method of heating and heat-treating a round material to be treated while conveying it using drum-shaped rolls, the material to be treated is conveyed in the longitudinal direction and processed, but the strength of the roll and the rotation mechanism of the roll in a high-temperature continuous heat treatment furnace, etc. Therefore, it is common to process a single material, and it is difficult to process multiple materials, resulting in a disadvantage of poor processing efficiency. On the other hand, in the case of the walking beam method, the material to be treated is transferred laterally while passing through the heating zone, but when it is fed into the heating zone or taken out, it is carried out in a single piece.
Again, the drawback was that the heat treatment efficiency was poor.
During heat treatment transfer, the treated material is oxidized due to the high temperature inside the furnace, but in the case of the roll conveyance method, seizure occurs on the roll surface, and in the walking beam method, oxidized scale is formed on the contact area between the treated material and the beam. There were cases where the material was piled up and damaged the surface of the treated material.
本発明では上記欠点を克服するために、

Thus, the processing material B sent from the previous device is conveyed in the longitudinal direction while being rotated by the heating conveyance device X, and is uniformly heated in the heating zone 1 during this time. If a walking beam conveyance device that conveys the treatment material B in the longitudinal direction is adopted as the heating conveyance device X, a large number of treatment materials B can be heat-treated at the same time, and efficiency can be improved. Also, the fixed beam 3 and the movable bracket 4
By making the treated material receiving surface a single inclined surface, oxide scale is not accumulated on the treated material receiving surface during transportation, so that the surface of the treated material B is not damaged by oxidized scale. Furthermore, uniform heat treatment becomes possible because the treatment material B is rotated and transferred by beam operation. When the temperature rise in heating zone 1 is completed, it is transferred to cooling and quenching zone 2, and when water-cooled quenching is performed in this cooling and quenching zone 2, quenching is performed with a cold water shower.
After quenching is completed, the first cooling conveyor Y can rapidly send the material to be treated in the advancing direction, or the first cooling conveyor Y can be switched to the second cooling conveyor and the material B can be conveyed approximately in the longitudinal direction. Processing material B in the perpendicular direction
transport. In this way, continuous operation is performed by classifying the delivery destinations into three locations, such as water quenching, oil quenching, annealing, etc., in accordance with changes in the heat treatment conditions of treated material B and differences in the treated material.

Embodiments of the present invention will be explained in detail with reference to the drawings.
The figure is a schematic plan sectional view of the inside of a continuous heat treatment furnace for a walking beam according to the present invention, and FIG. 2 is a side sectional view of the same. In this example, the treated material B is
Although this example shows parallel processing, processing material B
The number of can be increased or decreased as appropriate. 1 is a heating zone of a walking beam continuous heat treatment furnace, and 2 is a cooling and quenching zone, where the treated material B, which has been heated and transferred from heating zone 1, is quenched or left as is in three directions. It is now possible to change the direction and send it out. The lengths of the heating zone 1 and the cooling hardening zone 2 shown in the drawings are determined by the respective heat treatment conditions. In the heating zone 1, numeral 3 is a fixed beam, and 4 is a movable receiving metal fitting, the details of which are shown in cross-sectional view in FIGS. It is shown in FIG. 3 and FIG. 4, which is a sectional view taken from RO to RO in FIG. 1. Reference numeral 5 in the cooling and hardening zone 2 denotes a rapid conveyance roller which together with the next movable receiving metal fitting 6 constitutes a first cooling conveyance device Y, the details of which are shown in FIG. 6 is a movable receiving metal fitting, the details of which are shown in FIG. Reference numeral 7 designates a chain conveyor that delivers the processed material B to the left and right in a direction perpendicular to its longitudinal direction, and constitutes a second cooling conveying device Z, the details of which are shown in FIG. Reference numeral 8 denotes a conveying roller on which the treated material B is placed when it leaves the cooling zone 2 and is further transported forward, and conveys the treated material B to the next process. Reference numeral 9 denotes an operation stand, which is connected to the hearth 11 of the heating zone 1.
The hearth 1 is provided below the
1 and supports a processing material moving receiving metal fitting 4. The fixed beam 3 is erected on the hearth 11 by supporting columns 12. As shown in FIGS. 3 and 4, the processing material receiving surfaces of the fixed beam 3 and the movable receiving bracket 4 for the processing material B are single inclined surfaces facing inward, and the processing material B is alternately supported in contact with the front and rear sides. The front and rear fixed beams 3, 3 and movable brackets 4, 4 form a V.
The processing material B is supported by combining the processing material receiving groove 3a and the processing material conveying groove 4a. The combined positions of the processing material receiving groove 3a and the processing material conveying groove 4a are shifted from each other as shown in FIGS. 8 and 9.
In the cooling and hardening zone 2, the rapid conveyance roller 5 is installed on a pedestal 13 and is driven by a motor (not shown) via chain gears 18 and 19. However, when the processing material B is being moved in the longitudinal direction by the moving receiving fitting 6, the conveying roller 5 does not rotate but is stopped, and serves as the fixed beam 3 when the moving receiving fitting 6 is operated. . The movable receiving metal fitting 6 supports and moves the processing material B by forming a V-shape with a pair of front and rear movable receiving metal fittings 6, 6 in the same manner as the movable receiving metal fitting 4 in the heating zone 1. The movable receiving metal fitting 6 is connected and fixed to the operation frame 14 by a support 15. As shown in FIG. 7, the chain conveyor 7 is equipped with a receiving fitting 20 for placing and conveying the processing material B.
A plurality of chain conveyors 7 are arranged so as to move in a direction substantially perpendicular to the longitudinal direction of the processed material B, and this chain conveyor 7 is stretched between chain gears 17 attached to a main shaft 21 installed on a frame 16. has been done. chain gear 1
7 is a motor connected by a main shaft 21 (not shown)
It is designed to be able to rotate in either forward or reverse directions. The pedestal 16 is raised and lowered by a lifting device 22, and the processing material B can be lifted by a receiving metal fitting 20 and transferred in either the left or right direction. 23 is a discharge skid for processing material B. 24 shown in FIGS. 2 and 6 is a shower pipe for water-cooled quenching, which is installed from the ceiling of the cooling and quenching zone 2 to below the treated material B, so that water can be injected from around the treated material B. A water spray nozzle 25 is provided. The shower pipe 24 is attached to a mounting pedestal 26, and the pedestal 26 is elevated by a lifting device 27 such as a hydraulic cylinder, so that it can be raised and lowered. Also, the movement of the movable brackets 4 and 6 is as follows.
As shown in FIG. Let Z be the axis of the processing material B placed on the fixed beam 3, and let a point on this axis Z be a. When the processing material B on the fixed beam 3 is scooped up by the moving receiving fitting 4 and transferred onto the moving receiving fitting 4, the processing material conveying groove 4a of the moving receiving fitting 4 is eccentric by h 1 with respect to the axis Z. Therefore, the processing material B rotates in the direction of the arrow (clockwise). The axis at this time is Z1 . Next, treated material B
While placing the on the moving bracket 4, move from point b to c.
Move forward diagonally across the axis Z to the point. Here, h 1 = h 2 . Also, the axis at this time is Z2 .
When the treated material B is eccentric by h 1 + h 2 = H and advances to point C, it descends and the fixed beam 3 is fixed by the movable receiving bracket 4.
When being transferred to , the processed material B is rotated in the direction of the arrow (clockwise) by an amount corresponding to the eccentricity h, and point a moves to point d on axis Z. The operational relationship between the conveying roller 5 in the cooling and hardening zone 2 (which functions in the same way as the fixed beam 3 when stopped) and the movable receiving metal fitting 6 is also the same as in the above case.

い様に最下点に落としてある。 With the above configuration, a conveying device (not shown) having the same structure as the fixed beam 3 and movable receiving bracket 4 in the heating zone 1 is now installed on the entrance side of the heating zone 1,
This pre-equipment is synchronized with the movement of the moving beam 4 in the heating zone 1, and the material B to be treated is transferred to the heating zone 1 while rotating, and the material B to be treated is heated and heated sequentially from the leading end in the direction of movement. At this time, the oxidized scale generated from the treated material B falls without being deposited on the fixed beam 3 or the movable bracket 4 because the contact surfaces of the fixed beam 3 and the movable bracket 4 are sloped. . Next, the treated material B whose temperature has been raised in the heating zone 1 is transferred to the cooling and quenching zone 2 by the movable receiving metal fitting 4 and the fixed beam 3.
It is transported while rotating. Cooling and hardening zone 2
The inner conveyor roller 5 has stopped rotating, and the chain conveyor 7 has been lowered to the lowest point so as not to obstruct the feeding and passage of the processing material B.

焼鈍を実施する。 When conveying the treated material B continuously in the longitudinal direction, the moving receiving metal fitting 6 of the cooling and quenching zone 2 uses the conveying roller 5 as the fixed beam 3, and moves the treated material B in synchronization with the moving receiving metal fitting 4 in the heating zone 1. The material is transferred through the cooling and hardening zone 2 while rotating. The cooling and quenching zone 2 has a shower pipe 24 for water-cooling and quenching, and spray injection positions are arranged in multiple stages with respect to the direction in which the treated material B travels. The spray nozzle 25 provided in the shower piping 24 is designed to spray quenching water from three places on the circumference at each stage, and rotates the treated material B while moving the sprayed water, uniformly starting from the tip.

The processed material is rapidly transferred onto a feed roller 8 disposed at an external processing material mounting location connected to the longitudinal direction of the processing material. Conversely, when water quenching is not performed, water is not emitted from the spray nozzle 25 and the cylinder 27
The shower pipe 24 is raised together with the mounting pedestal 26, and when the treated material B is transferred from the heating zone 1 to the cooling and quenching zone 2, the chain conveyor 7 is raised together with the pedestal 16 by the lifting device 22, and the treated material B is carried out. It is lifted up from above the roller 5 by the receiving metal fitting 20, sent to either the left or right oil tank or cooling table, and subjected to oil quenching or annealing.

Since the second transport device for the cooling and hardening zone is provided in the cooling and hardening zone, the processing material sent from the cooling and hardening zone can be transferred by selecting the direction of movement or in a direction almost perpendicular to the direction of movement, and the material of the processing material can be transferred. Classification based on differences in quenching specifications or quenching specifications can be carried out continuously, which is highly effective in improving operational efficiency and quality of processed materials.
