AI Technical Summary
During the welding process, the temperature of existing ceramic liners is too high due to the thermal conductivity of the steel plate, which leads to the flow of self-adhesive and the adhesion is reduced, and the pads are deformed or dropped, which affects the quality of the weld. When welding special materials, excessive temperature will cause self-adhesive and carbonized, resulting in black deposition, and reduce production efficiency.
A double-sided bevel welding ceramic liner is designed, using a combined structure of substrate, ceramic gasket, magnet bar, elastic pad and reinforced coating. It is fixed by magnet bar, sealed by elastic pad and insulation and alumina coating to avoid the use of self-adhesive adhesives.
The ceramic liner is fixed by magnet bars and sealed with elastic pads, avoiding glue residue and carbonization, improving welding quality and production efficiency, and extending the service life of the liner by enhancing coating insulation.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shipbuilding, in particular to a ceramic liner for double-sided groove welding. Background Art
[0002] Shipbuilding and marine engineering is a complex steel structure construction process, and welding technology is an important connection technology in its construction process. Large steel plates with a thickness of 16 mm and above are often used in the field of shipbuilding and marine engineering. In order to meet the welding quality requirements of relevant specifications, double V grooves need to be opened at the connection parts.
[0003] The shaping of the weld root is crucial to the welding quality. The current mainstream technology is to use back carbon arc gouging to clean the weld and then re-weld. Although this back root cleaning technology can ensure the welding quality, it requires the operator to have high skills and is not easy to master; at the same time, the root cleaning process requires sufficient operating space and is difficult to operate in a narrow area; in addition, dust, noise, arc light and other pollutants will be generated during the root cleaning process, which is harmful to the health of the workers. The use of pad welding shaping has become a more reliable solution.
[0004] However, most of the existing ceramic gaskets are made of ceramic powder that is pressed at one time, and then aluminum foil and self-adhesive are connected to the bottom surface. When in use, the gasket is connected to the back of the steel plate to be welded by gluing. However, the thermal conductivity of the steel plate causes the temperature to be transferred quickly during the welding process, thereby increasing the temperature of the bonding point. When the temperature of the self-adhesive is too high, it will flow, which greatly reduces the adhesion, causing the gasket to deform or even fall off, greatly affecting the quality of the weld. When welding some special materials, excessively high temperatures will carbonize the self-adhesive, and mix with welding slag and debris to produce black deposits on the surface of the weld, which need to be manually polished and removed, reducing production efficiency. Utility Model Content
[0005] The utility model aims to provide a ceramic liner for double-sided groove welding with a reasonable design to solve the defects and shortcomings of the prior art.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a substrate, a strip-shaped ceramic gasket is connected to the top of the substrate, an arc-shaped groove is opened on the top of the ceramic gasket, magnet strips are respectively embedded in the two ends of the upper side of the substrate, elastic pads are respectively embedded on both sides of the ceramic gasket, and the top of the ceramic gasket and the surface of the arc-shaped groove are provided with a reinforcing coating.
[0007] Preferably, both corners on the top side of the ceramic gasket are arc-shaped.

[0011] After adopting the above structure, the beneficial effects of the utility model are:
[0012] This ceramic liner uses an alumina reinforced coating to reduce the impact of high temperature on the underlying components, while reducing the wear on the underlying ceramic gasket during welding and increasing the service life of the product.
[0013] The ceramic liner is fixed with a magnet strip instead of a self-adhesive sticker, and will not produce glue residue or carbonization when in use. It is easy to load and unload through magnetic adsorption, and can be disassembled and assembled multiple times without damaging the connection parts.
[0014] The ceramic liner is provided with an elastic pad, which can utilize elasticity to enhance sealing during installation and reduce the risk of molten iron leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-Figure 3As shown, it comprises a substrate 1, a strip-shaped ceramic gasket 3 is connected above the substrate 1, an arc-shaped groove 4 is opened on the top of the ceramic gasket 3, magnet strips 2 are respectively embedded in the two ends of the upper side of the substrate 1, elastic pads 5 are respectively embedded on both sides of the ceramic gasket 3, and a reinforcing coating 6 is provided on the top of the ceramic gasket 3 and the surface of the arc-shaped groove 4;
[0022] The two corners on the top side of the ceramic gasket 3 are both arc-shaped;
[0023] The substrate 1 is an aluminum plate or a copper plate, and the magnet bar 2 is a permanent magnet;
[0024] The elastic pad 5 is a high-temperature rubber pad, and the reinforcing coating 6 is an aluminum oxide coating;
[0025] The principle and use process of this utility model:
[0026] First, grind the welding parts of the two steel plates to be welded, and then prepare several ceramic liners according to the length requirements, and place the ceramic gasket 3 of the ceramic liners directly against the joint seam of the steel plates, and then push the base plate 1 toward the steel plates. When the two magnet strips 2 gradually approach the steel plates, the magnet strips 2 are automatically adsorbed onto the steel plates, thereby driving the entire ceramic liners to be fixed to the steel plates. At the same time, the elastic pad 5 can automatically adapt to the uneven position of the interface, thereby preventing the leakage of molten iron caused by the generation of large gaps, and then welding can begin;
[0027] During the welding process, the reinforcing coating 6 isolates the heat in the molten iron above, reducing the heat transfer to the ceramic gasket 3 and the elastic pad 5 below, thereby reducing the temperature of the lower parts. In addition, the alumina ceramic has the advantages of high hardness and wear resistance, which can extend the service life of the gasket;
[0028] After the welding is completed, the operator can hold the substrate 1 from both sides and pull it downward after the temperature drops, thereby removing the pad and moving it to the next welding position for recycling.
