New description: [New technical field] This creation belongs to the technical field of continuous atmosphere sintering furnace, especially for the new design of the hearth furnace structure in the push-plate continuous atmosphere sintering furnace, which avoids the deformation of the track. Avoid pushing the board and reducing the temperature gradient to achieve the average temperature. [Prior Art] According to 'in the process of electronic components or powder metallurgy materials, it is necessary to introduce different atmosphere gases to sinter or heat treatment in the furnace. 'Sintering or heat treatment is a very important process' because of the sintering or heat treatment process The quality of components or powder metallurgy materials. The creator of the present invention has previously achieved a strict control of the sintering atmosphere in the furnace in a continuous atmosphere sintering furnace, such as "continuous vacuum atmosphere sintering furnace" No. 097204412, "Pushing plate type continuous atmosphere sintering furnace", etc. Taking Patent No. 093216847 as an example, the patent mainly consists of a furnace body, an inner conveying lane, an outer conveying lane and an exchange system, and the inner conveying lane is disposed inside the furnace body and is connected to the two sides of the furnace body for exchange. The system, the outer conveying channel is arranged outside the furnace body, and connects the exchange system on the two sides of the furnace body as a conveying platform for placing the electronic component carrier to be sintered, the furnace body is sealed and introduced into the atmosphere for protection or reaction. The gas is divided into a heating section and a cooling section according to the process, and the heating element has a heat-resistant material and a heating element according to a temperature required for the sintering process, and the cooling section has a cooling device, and the exchange system provided on each side of the furnace body has The second airtight door is changed to form a raft. Before the vehicle is sent into the furnace body, the two airtight doors at the head end of the furnace body are closed for the seal 3 M437446, and the chamber to be exchanged is evacuated and the atmosphere gas is introduced to the furnace. After the same atmosphere in the body, the inner side of the furnace is opened to push the carrier into the furnace. When the carrier is to be sent out of the furnace, the two airtight doors at the end of the furnace are closed, and the exchange room has been pumped. Vacuum and introduce atmospheric gas In the same atmosphere as in the furnace, the airtight door on the inside of the furnace opens into the exchange chamber, which has the effect of avoiding the mixing of the furnace air into the furnace to improve the quality of sintering heat treatment such as electronic components. However, in the case of the push-type continuous atmosphere sintering furnace, the length of the plate is limited to be too long. Further, • Please refer to the first figure, the hearth (B) for the push plate (A) is made of refractory material and has a block of concave parts (C). Due to the limitation of the process, each The size of the refractory block is limited, and because it is a solid refractory block, the hearth is liable to be caused by the expansion change, and the push plate carried by the hearth is not smooth, even the convex plate. Furthermore, since the sintering heat treatment process for products such as electronic component powder metallurgy powder materials is required to increase the productivity, it is necessary to increase the volume and speed up. However, if the volume is increased by height, it will be affected by the joy of the forest, and the energy efficiency of the growth can only be widened and lengthened. In order to average the temperature gradient of the sintering heat treatment, the upper and lower heating modes are prepared. That is, the heating element (8) is placed on the upper and lower ends of the secreting material to be sintered, and the learner is placed on the solid hearth by the pusher plate, and the high temperature f generated by the lower heater is transmitted through the solid bed to the square material to be sintered. This results in the absence of uneven temperature gradients between the upper and lower parts, which seriously affects the quality of the sintering. This is the biggest deficiency in the current use of technology, and this lack is a difficult problem to be overcome in the industry. 4 M437446 [New Content] In view of the lack of conventional technology, this creative researcher has accumulated many years of experience in the design and manufacturing of fine ceramics technology industrial products. After continuous research and improvement, the company has succeeded in creating and creating this creation. Yu Shi. The reason is that the main purpose of this creation is to provide a "furnace structure improvement". This creation is especially for the new design of the hearth furnace structure in the push-plate continuous atmosphere sintering furnace, which is mainly used in the push-plate continuous atmosphere sintering furnace. A plurality of bottom rails are arranged on the inner side of the two side rails at the opposite positions of the two side rails, and the side rails are formed between the side rails and the bottom rails, and the side rails and the bottom rails have the side rails and the bottom rails. The S part of the middle section avoids the shape of the money by reducing the number of expansions, and has the effect of avoiding the push plate to reduce the temperature gradient and reach the average temperature. The above-mentioned side and bottom rails of this creation can be made of tantalum carbide, which can obtain better heat conduction, heat resistance and lubrication. The bottom rails of the present invention are long and can be staggered to avoid the connection of adjacent bottom rails at the same position, so that the push plate travels more smoothly, and the pusher can be avoided. This creation just described the gap between the bottom rails. The lower heater can directly heat the push plate through the gap, which can achieve the effect of reducing the temperature gradient and reaching the average temperature. [Embodiment] In order to achieve the above-mentioned technical means of the present invention, it is possible to obtain a better understanding of the structure, characteristics, and effects achieved by the review committee. 5 This creation is specially designed for the new design of the hearth furnace structure in the push-plate continuous atmosphere sintering furnace. Please refer to the second and third figures. The figure shows that the creation is mainly based on the rail support of the push-plate continuous atmosphere sintering furnace. Side seat (2) is set on the opposite side of the seat (1), and several track bottom rails (3) are set on the rail support seat (1) on the inner side of the two side rails (2). The side rails (2) and the bottom handle (3) Between the two) having a recess (4), which constitutes the trajectory of the push plate (5). The aforementioned side rail (2) and the bottom rail (3) have a hollow portion (20) (30), and the side rail (2) and the bottom (3) The design of the hollow portion (20) (30) can reduce the expansion coefficient of the side rail (2) and the bottom rail (3), thereby avoiding deformation of the side rail (2) and the bottom rail (3), and the bottom heating element (6) When the hollow part (20) (30) is passed through: the heating element to be sintered on the push plate (5) is heated, so that the push plate (5) plate is tilted and the temperature gradient is reduced. The effect of temperature. The above-mentioned side rails (2) and bottom rails (3) of the present invention can be made of tantalum carbide SiC, and can obtain better thermal conductivity, heat resistance and lubricity. Please refer to the second and third figures. 'The above-mentioned bottom rail (3) and side rails (2) are long strips' and are arranged for staggered joints [adjacent bottom rail (3) or side rail (2) to avoid At the same junction (9), the staggered connection is formed, and because the length that can be manufactured in the process is large, the joint (9) is reduced, so that the push plate (5) can be made smoother and can Avoid pushing the board (5). Please refer to the third figure, 'There is a gap (8) between the bottom rails (3), and the lower heater (6) can directly heat the components to be sintered on the push plate (5) through the gap (8). When the temperature gradient is reduced, the effect of the average temperature can be achieved. In this way, the purpose of this creation is a practical creator. M437446 In summary, the "burning bed structure improvement" disclosed in this creation is none, and it has not been seen in the publications of _ outside publications, which have been designed to be novel, and the creation of marriage can be eliminated. And to achieve the design purpose, it has also fully complied with the patent requirements for the new type of patents that can be used in the industry, and submitted the application in accordance with the law. I would like to ask your review board to give a review and give the patent in this case. However, the above is only a preferred and feasible embodiment of this creation, and is not intended to be used in the context of the system. For those who are familiar with the art, the equivalent structure of the scope of the application and the scope of the patent is applied. Changes are intended to be included in the scope of this creation's patents. [Simple description of the map]
