Description
Technical Field
The utility model relates to a fritting furnace specifically is a fritting furnace boiler tube.
Background
The product is placed in a molybdenum boat, and the required physical and mechanical properties and microstructure are obtained by sintering treatment in a high-temperature sintering furnace tube. The prior sintering furnace tube is shown in figure 1, the top of the furnace tube is arched, and a molybdenum boat is placed on the bottom wall plane of the furnace tube, so that the structure causes some problems in the sintering process of products:
1. in order to be suitable for sintering products in molybdenum boats with different heights, the height of the furnace tube is set to be higher, so that the distance between the top of the furnace tube and the top of the uppermost product of the molybdenum boat is larger, when the internal temperature of the sintering furnace is higher, the heat conduction mode is a radiation mode, the furnace tube is far away from one side of the product, the product is heated unevenly, the mechanical property of the sintered product is influenced, and the sintering effect is poor.
2. The molybdenum boat is directly placed on the bottom wall plane of the furnace tube and is pushed one by one, and the bottom surface of the molybdenum boat is abraded seriously due to long-time friction between the bottom surface of the molybdenum boat and the bottom wall of the furnace tube, so that the service life of the molybdenum boat is shortened, and the molybdenum boat needs to be replaced frequently.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned problem, provide a sintering furnace boiler tube, its simple structure, convenient operation makes molybdenum boat life extension, and the product in the molybdenum boat is heated more evenly.
The technical scheme of the utility model is that:
the utility model provides a sintering furnace boiler tube, includes the boiler tube body, boiler tube body top is the arch, and the bottom is the plane, and its technical essential is: the furnace tube body bottom upper surface sliding connection has the detachable to increase the ejector pad, it is equipped with the gas cell group to increase the ejector pad top.
In the sintering furnace tube, the length and the width of the heightening push block are both larger than those of the molybdenum boat, and after the product is placed on the heightening push block, the vertical distance between the top of the uppermost product and the lowest point of the top of the arched furnace tube body is not larger than the horizontal distance from the side surface of the molybdenum boat to the side wall of the furnace tube body closest to the molybdenum boat.
The gas passing groove group comprises a plurality of vertical gas passing grooves formed by the upper surface of the heightening sliding block in a concave mode along the length direction of the furnace tube and a plurality of transverse gas passing grooves perpendicular to the vertical gas passing grooves.
The utility model has the advantages that:
1. only by additionally arranging the heightening push block between the bottom surface of the furnace tube body and the molybdenum boat, two problems are solved: the distance between the top of the furnace tube body and the top of the uppermost product of the molybdenum boat is shortened, so that the products are heated more uniformly, the mechanical property of the sintered products is improved, and the sintering effect is better; the product is placed on the heightening push block and is not contacted with the bottom of the furnace tube body, and only the heightening push block needs to be pushed in the sintering process, so that the friction damage of the bottom surface of the molybdenum boat is greatly reduced, and the service life of the molybdenum boat is prolonged.
2. The heightening push block is in sliding connection with the upper surface of the bottom of the furnace tube body, so that the abrasion degree of the bottom of the furnace tube body is extremely small, and the heightening push block can be detached and replaced according to the difference of the heights of the molybdenum boats, so that the distance between the top of the furnace tube body and the top of the uppermost layer product of the molybdenum boat is kept, and the heating condition and the sintering effect of the product are guaranteed.
3. The gas passing groove is arranged at the top of the heightening push block, so that the contact area between the molybdenum boat and the heightening push block is reduced, sintering gas can pass through the bottom surface of the molybdenum boat, heat energy transfer is smoother, the product is heated more uniformly, and the sintering effect is better.
Drawings
FIG. 1 is a schematic structural diagram of a furnace tube of a conventional sintering furnace;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a schematic top view of the height increasing push block of fig. 2 according to the present invention.
In the figure: 1. the furnace tube comprises a furnace tube body, 2 molybdenum boats, 3 heightening push blocks, 4 gas passing groove groups, 5 vertical gas passing grooves and 6 transverse gas passing grooves.
Detailed Description
The technical solution of the present invention is further explained by the following specific embodiments with reference to the accompanying drawings.
As shown in fig. 2-3, the sintering furnace tube includes a furnace tube body 1, wherein the top of the furnace tube body 1 is arched and the bottom is a plane.
Wherein, furnace tube body 1 bottom upper surface sliding connection has detachable to increase ejector pad 3, it is equipped with air duct group 4 to increase the ejector pad 3 top.
In this embodiment, the length and width of the height increasing push block 3 are both greater than those of the molybdenum boat 2, and after the product is placed on the height increasing push block 3, the vertical distance between the top of the uppermost product and the lowest point of the top of the arched furnace tube body 1 is not greater than the horizontal distance from the side of the molybdenum boat 2 to the side wall of the furnace tube body 1 closest to the side of the uppermost product. The air passing groove group 4 comprises five vertical air passing grooves 5 formed by sinking the upper surface of the heightening slide block along the length direction of the furnace tube and five transverse air passing grooves 6 vertical to the vertical air passing grooves 5. The contact surface between the bottom of the furnace tube body 1 and the heightening push block 3 is covered with a high-temperature resistant and wear-resistant coating.
During the use, will arrange the molybdenum boat 2 of product and place on increasing ejector pad 3, promote to increase ejector pad 3 and drive molybdenum boat 2 and get into furnace tube body 1, furnace tube body 1 top is close to the upper product, increases the gas groove on the ejector pad 3 and makes sintering gas smoothly flow in the product bottom, and the product is heated evenly, and sintering effect is good.
