The invention relates to the technical field of upper cover tape processing, and discloses a uniform gluing device for heat-seal upper cover tape processing, which comprises a base, an unwinding roller is mounted on one side of the top of the base through a frame body, a plurality of support frames are fixedly connected to one side, close to the support frames, of the top of the base, and a cleaning mechanism is arranged at the end parts of the plurality of support frames. A limiting frame is fixedly connected to the side, close to the supporting frame, of the top of the base, a gluing mechanism is arranged outside the limiting frame, a slicking mechanism is arranged on the side, close to the gluing mechanism, of the bottom of the limiting frame, and an edge scraping mechanism is arranged on the side, close to the slicking mechanism, of the bottom of the limiting frame. And a glue collecting mechanism is arranged on the inner side of the limiting frame. The scraping plate and the connecting rod are fixed, and the torsion spring provides elastic pressure, so that the scraping plate can flexibly adapt to different glue thicknesses and scrape redundant glue, and the thickness uniformity of a gluing layer of the upper cover belt is guaranteed.

The application discloses an alloy cushion block for a large walking beam heating furnace and a preparation method thereof, and the preparation method comprises the following steps: S1, determining the melting point of the alloy cushion block based on the atomic penetration depth of an alloy B containing FeO on multiple different alloy A with a melting point higher than that of the alloy B; S2, studying the load-bearing condition of the alloy cushion block to determine the required compressive strength; S3, designing the composition of the alloy cushion block; and S4, carrying out the industrial design of the alloy cushion block and starting smelting. Through reasonable alloy composition and production process design, the application provides a high-temperature heat-resistant alloy cushion block, improves the strength and melting point of the alloy cushion block, enables the alloy cushion block to maintain high strength at high temperature, solves the problem of FeO bonding in a molten state, reduces the phenomenon of heating furnace nodulation, and has universality and is suitable for various casting processes.

The invention relates to a preparation method of a super-uranium nuclide glass solidified body. The preparation method of the super-uranium nuclide glass solidified body comprises the following steps: 1) mixing granite powder and boron oxide powder, and calcining to obtain granite glass body powder; 2) uniformly mixing cerium oxide and neodymium oxide to obtain cerium-neodymium oxide; 3) mixing the cerium-neodymium oxide with the granite glass body powder to obtain a base material, adding a super-uranium nuclide, adding a mixed medium, uniformly mixing, and performing compression molding to obtain a molded body; and 4) calcining the molded body for 1-3 hours at the temperature of 1200-1400 DEG C in an inert atmosphere to obtain the ultra-uranium nuclide glass solidified body. According to the preparation method disclosed by the invention, the cerium-neodymium oxide is used for cooperating with the granite glass body powder to solidify the super-uranium nuclide under a relatively mild condition, so that the bonding problem of a crucible and a solidified body during solidification and sintering is solved, and the super-uranium nuclide glass solidified body with good chemical stability is obtained.
