Problems solved by technology

[0003] At present, the method of centrifugal casting is mainly used to produce rotating tin targets, but this method has the following problems: expensive equipment, high production cost; large equipment footprint, waste of space; complex production process, difficult to control the process; The grain size difference at both ends of the target is large, which affects the quality of the coating; a large number of pores are prone to appear inside the tin target, which causes arcing during the coating process and cannot be used normally.

[0029] A retaining spring 12 is arranged inside the positioning groove 6 .

[0030] One end of the cooler 16 is provided with a...

Embodiment 2

[0033] Embodiment 2 The production method of the mold for producing the rotating tin target, the steps are as follows:

[0034] (1) Baking mold: Baking the mold at 230°C for 65 minutes;

[0035] (2) Melting: Put tin ingots with a purity of 99.9% into an induction melting furnace, first melt them with a power of 35kw, and then refine them at 330°C for 20 minutes to obtain a casting solution;

[0036] (3) Casting: pour the casting solution obtained in step (2) into the mold cavity 8 outside the back pipe 1 through the casting port 9, and keep it warm at 330°C for 60 minutes;

[0037] (4) Cooling: Connect the cooler 16 to the mold, turn on the water inlet switch, the cooling water flows into the water inlet pipe interface 13 through the water pipe at a flow rate of 6 cubic meters per second, and then flows into the back pipe 1, and the water surface gradually rises from the water outlet pipe The interface 14 flows out, and flows into the water tank from the metal hose connected ...

Embodiment 3

[0039] The production method of the mold that produces the rotating tin target described in embodiment 3, the steps are as follows:

[0040] (1) Baking mold: bake the mold at 250°C for 55 minutes;

[0041] (2) Melting: put tin ingots with a purity of 99.9% into an induction melting furnace, first melt them with a power of 50kw, and then refine them at 280°C for 20 minutes to obtain a casting solution;

[0042] (3) Casting: pour the casting solution obtained in step (2) into the mold cavity 8 outside the back pipe 1 through the casting port 9, and keep it warm at 360°C for 40 minutes;

[0043] (4) Cooling: Connect the cooler 16 to the mold, turn on the water inlet switch, the cooling water flows into the water inlet pipe interface 13 through the water pipe at a flow rate of 2 cubic meters per second, and then flows into the back pipe 1, and the water surface gradually rises from the water outlet pipe The interface 14 flows out, and flows into the water tank from the metal hose...

Abstract

The invention relates to a die for producing a rotary tin target and a production method thereof, and belongs to the technical field of functional materials. The die comprises a back tube, and a cooler which is arranged in the back tube, wherein a die coating is arranged at the outer part of the back tube, and the bottom part of the die coating is welded to the back tube through a sealing ring; the upper part of the die coating is connected with the back tube through a supporting sheet; a connecting ring is arranged above the back tube; the upper part of the cooler is in contact with the connecting ring; the connecting ring and the connector are fastened through a fastener and is fixed through a bolt. The method is characterized in that the raw tin is obtained and smelted into casting liquid; the casting liquid is casted into a die which is used for producing the rotary tin target; the tin is completely solidified from bottom to top in a sequence in a manner of water cooling from the inside of the die; and then the die is released so as to obtain the rotary tin target. The tin target produced by the method is high in density, free of air pores, impurities and other defects, and small in crystal particles; in addition, the preparation process is simple; the cost is low; the repeatability is high; and mass industrial production can be carried out.

Description

technical field [0001] The invention relates to a mold for producing rotating tin targets and a production method thereof, belonging to the technical field of functional materials. Background technique [0002] In addition to its beautiful appearance, low-e glass also has excellent heat insulation effect and good light transmission, so it has been more and more widely used in buildings. The rotating tin target has a very important application in the low-e glass industry. [0003] At present, the method of centrifugal casting is mainly used to produce rotating tin targets, but this method has the following problems: expensive equipment, high production cost; large equipment footprint, waste of space; complex production process, difficult to control the process; The grain size difference at both ends of the target is large, which affects the quality of the coating; a large number of pores are prone to appear inside the tin target, which causes arcing during the coating proces...
