Embodiment 1
[0034] Such as image 3 , Figure 4 As shown, the fluorescent crack problem of a cast pure titanium casting is solved. The concrete steps of the inventive method are as follows:
[0035] First, before painting, double-sided adhesive tape is used to mark the oxyacetylene cutting part, and the width of the double-sided tape is 15mm; then, the casting part that may be touched by the flame or roasted is protected by high-temperature paint brushing the wall (protection of high-temperature paint Temperature ≥ 1700 ℃), coating thickness 1.5mm; tear off the top layer of double-sided adhesive tape, so that the flame cutting part is in a state of no coating; then cut the riser: keep the flame center cutting point 12mm away from the casting surface, Use the traditional oxyacetylene flame cutting method to cut off the casting from the gating system at the position marked by the sticker; finally, clean the coating of the casting after cutting: after cutting the spout, use water to blow s...

[0037] Such as Figure 5 , Image 6 The fluorescent crack problem of a ZTC4 cast titanium alloy ring casting shown is solved. The concrete steps that adopt technical scheme of the present invention are as follows:
[0038] First, before coating, mark the oxyacetylene cutting part with double-sided adhesive tape, the width of the double-sided adhesive tape is 15mm; then use high-temperature coating to completely immerse the casting to protect it (the protection temperature of high-temperature coating is ≥ 1700 ℃), and the coating Thickness 1.0mm; tear off the top layer of double-sided adhesive tape, so that the flame cutting part is in a state of no paint; then cut off the pouring riser: keep the cutting point of the flame center at a distance of 11mm from the casting surface, using the traditional oxyacetylene flame cutting method Cut off the casting from the pouring system facing the position marked by the sticker; finally, clean the coating of the casting after cutting: af...

[0040] Such as Figure 7 , Figure 8 As shown, the fluorescent crack problem of a ZTA15 cast titanium alloy frame casting is solved. The concrete steps that adopt technical solution of the present invention are as follows:
[0041] First, before coating, mark the oxyacetylene cutting part with a double-sided adhesive tape with a width of 10 mm; then use high-temperature paint to protect parts of the casting that may be touched by flames or baked for extra-large castings (protection temperature of high-temperature paint ≥1700℃) coating protection, the other part uses high-temperature coatings to completely immerse coating protection on the castings, the coating thickness is 1.2mm; tear off the top layer of double-sided adhesive tape, so that the flame cutting part is in a state of no coating; then carry out Removal of the pouring riser: Keep the cutting point of the flame center at a distance of 11mm from the surface of the casting, and use the traditional oxyacetylene flame ...
