Description

Technical Field

[0001] The utility model relates to the technical field of steel-titanium composite plates, in particular to a steel-titanium composite substrate. Background Art

[0002] Titanium composite steel plate is a material made of titanium plate and steel plate. Titanium has excellent corrosion resistance, but it is expensive. Making composite plates can greatly reduce costs. It is usually made by explosive pressing, and in recent years it has begun to be produced by hot rolling. At high temperatures, the joint surface of titanium and steel is prone to form TiC, titanium-iron solid solution phase and intermetallic compounds (TiFe, TiFe2, etc.), causing the steel plate to become embrittled. To prevent embrittlement, ultra-low carbon steel foil or stainless steel wire mesh with a carbon content of less than 50ppm can be used as the interlayer material between titanium and steel.

[0003] Although the existing steel-titanium composite substrate uses stainless steel mesh as the interlayer material between titanium and steel to prevent embrittlement during use, in the actual production process, due to the properties of titanium itself, it is not convenient to weld it with the steel plate, which leads to low connection strength between the titanium plate and the steel plate, resulting in the connection point between the two being easily broken during use, thus affecting its use effect. Therefore, a steel-titanium composite substrate is urgently needed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] The technical problem to be solved by the utility model is aimed at the current status of the prior art, and now provides a steel-titanium composite substrate with high connection strength, long service life and good use effect.

[0008] Furthermore, the connecting mesh is a stainless steel wire mesh with a carbon content of less than 50 ppm, and the connecting mesh is welded to the steel plate and the upper titanium plate and the lower titanium plate.

[0009] By adopting the above technical solution, the connecting net connects the upper titanium plate and the lower titanium plate with the steel plate, thereby forming a steel-titanium composite substrate.

[0010] Furthermore, the through cavity is formed on the steel plate, and the through cavity is a cross-shaped structure.

[0011] By adopting the above technical solution, the through cavity provides an installation space for the reinforcement rod.

[0012] Furthermore, the reinforcement rod is welded to the through cavity, and the reinforcement rod is a cross-shaped structure.

[0013] By adopting the above technical solution, the reinforcement rod can be integrated with the steel plate.

[0014] Furthermore, two ends of the reinforcement rod are respectively welded to the upper titanium plate and the lower titanium plate.

[0015] By adopting the above technical solution, the reinforcing rod can connect the upper titanium plate and the lower titanium plate as a whole, thereby strengthening the connection between the steel plate and the upper titanium plate and the lower titanium plate, effectively improving the strength of the connection point.

[0016] Furthermore, the material of the reinforcement rod is consistent with that of the upper titanium plate and the lower titanium plate, which are all titanium.

[0017] By adopting the above technical solution, it is convenient to weld the reinforcing rod to the upper titanium plate and the lower titanium plate, and the strength of the welding points is ensured.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] In order to solve the problem that the existing steel-titanium composite substrate uses stainless steel mesh as the interlayer material between titanium and steel to prevent embrittlement during use, but in the actual production process, due to the properties of titanium itself, it is not convenient to weld it with the steel plate, which leads to low connection strength between the titanium plate and the steel plate, resulting in the connection point between the two being easily broken during use, thus affecting its use effect, the utility model provides a cross-shaped cavity and a reinforcement rod, and the material of the reinforcement rod is titanium. By welding the reinforcement rod in the cavity and between the upper titanium plate and the lower titanium plate, the connection between the steel plate and the upper titanium plate and the lower titanium plate can be strengthened, thereby effectively improving the strength of the connection point, avoiding the short service life due to the breakage of the connection point during use, and effectively improving its use effect.
