Silicon nitride riser tube/stalk tube is the ideal material for non-ferrous metallurgy industry because of its excellent characteristics like corrosion resistance, low thermal-expansion coefficient and thermal shock resistance. It not only can improve the quality of casted products but also can decrease the cost of tubes and handling. The service life of silicon nitride stalk tube is 5-20 times longer than the traditional dosing tube, so the down time for equipment is reduced and the continuity of the production is ensured.

Application:

Silicon nitride dosing tube is widely used in the aluminum smelting industry , petroleum chemical industry, ceramic industry and electronics industry.

Notice:

1. Avoid giving mechanical shock on tube. No hammering is allowed and adhered aluminum on tubes should be removed by scraping or grinding.

2. No preheating on drying process before usage and on starting operation are required Immerse slowly into liquid after wiping off water on tube surface.

3. Partial heating by burner or rapid cooling by water should be absolutely avoided in order to minimize thermal shock. Partial abrupt thermal shock causes breakage of tube.
