Detailed Description

The invention is further explained by the accompanying drawings.

The tin product casting heat preservation feeding device shown in figure 1 comprises a supporting bottom plate 4 built by refractory bricks, a rectangular shell 1 which is arranged on the supporting bottom plate and welded by steel plates, a refractory material layer 2 built on the inner wall of the shell, an electric heating device 3 which is arranged on the refractory material layer of the side wall in a surrounding manner, a pot body 7 which is arranged in the inner cavity of the refractory material layer and the bottom of the pot body is arranged on the supporting bottom plate 4, and a top cover plate 10 which covers the pot body. The upper part of the pot body is provided with a liquid inlet 9 which penetrates through the refractory material layer and the shell to be connected with the tin smelting pot, an upper part return port 5 which penetrates through the refractory material layer and the shell to be connected with the smelting pot, and the bottom surface of the pot body is provided with a bottom return port 6 which penetrates through the refractory material layer and the shell and is provided with a bottom valve 8. When the liquid level in the heat preservation pot is too high, the tin liquid can flow back into the melting pot from the return opening 5, so that the safety is ensured. A thermocouple 11 inserted into the pot body and a tin pump 12 with a pump shaft 12a inserted into the pot body downwards are arranged on the top cover plate 10, and the tin liquid is sent into the linear ingot casting machine from a tin liquid pipe 12b through the tin pump 12. The electric heating device 3 can be a resistance wire or an electric heating plate. The thermocouple and the electric heating device 3 are connected with a temperature control instrument. As shown in figure 2, the pan body 7 is an elliptic cylindrical pan body, and other devices connected with the pan body, such as a tin pump, a thermocouple and the like, can be easily arranged in the longitudinal direction while the occupied area is small.

The tin product casting heat-preservation feeding device is an intermediate transition device which is arranged at the front end of a linear ingot casting machine and is used for tin ingot casting, and the feeding method of the tin product casting heat-preservation feeding device comprises the steps of transferring tin liquid melted by a tin melting pot into a pot body 7 through a liquid inlet 9 for storage and heat preservation, and enabling the tin liquid in the pot body to enter the linear ingot casting machine through a tin liquid pipe 12b of a tin pump 12 for tin ingot casting. The electric heating device 3 is started and stopped according to the set tin liquid temperature in the casting process, when the thermocouple detects that the temperature of the tin liquid in the pot body is lower than a lower limit value, temperature information is transmitted to the temperature control instrument, and the temperature control instrument starts the electric heating device to heat the pot body; and if the temperature is higher than the upper limit value, the electric heating device stops, so that the temperature fluctuation of the tin liquid is small, and the liquid level is stable. The tin liquid level in the pot body is too high and can flow back to the melting pot through the backflow port 5 at the upper part; and when cleaning, the bottom valve 8 on the bottom return port 6 is opened for cleaning.

The invention provides stable liquid level and temperature conditions for tin product casting, ensures high-quality tin product casting, and can greatly reduce the product rejection rate.
