5. How to reduce tin bar slag rate (tin oxide)?
A: The slag of the tin bar is due to the oxidation reaction between the tin and the oxygen in the air, which is a normal phenomenon. The raw materials used by our company are all Yunnan tin ingots, the quality of tin bars is the best, and the output of tin oxides is very low. Other companies have added recycled materials, and the output of tin oxide is on the high side; please ensure that the furnace temperature is running at the correct temperature. If the temperature is too low or too high, it will affect the excess of tin oxide; it is also possible to appropriately add reducing agents in the furnace , can also reduce the generation of tin oxide.
6.Why is the surface of the tin bar not bright enough?
A: There may be a layer of light traces left on the surface of the upper end of the tin bar, which is antioxidant. Antioxidants have been added to our tin bar products to ensure that the tin oxide generated when the tin bar is used is reduced and better for customers.
