Product Photos:
Refractory sliding plates play a crucial and indispensable role in numerous high-temperature industrial fields such as metallurgy and casting. The following elaborates on their specific applications:
I. Steel Metallurgy Industry
-
Ladles: Bottom-mounted refractory sliding plate stops leakage after tapping molten steel from converters. Mechanically/hydraulically operated at refining/casting stations to control flow into furnaces/tundishes, reducing oxidation via multi-cycle opening/closing.
-
Tundishes: Key transition for molten steel from ladles to molds. Refractory sliding plates regulate flow for stable continuous casting, with quick closing during mold issues (e.g., breakouts) to secure production.
II. Non-ferrous Metal Metallurgy Industry
-
Copper Smelting: Refractory sliding plates control copper liquid flow between smelting/refining equipment. Require high corrosion resistance and sealing (due to copper properties), with special materials to prevent erosion/leakage for process continuity.
-
Aluminum Electrolysis: Used post-purification to control flow into casting molds. Adapts to low-viscosity aluminum for smooth, precise operation and higher efficiency.
III. Casting Industry
-
Cast Iron Casting: Bottom-mounted refractory sliding plates control molten iron flow. Operators open them for even pouring (to prevent defects) and close quickly during batches for mold changes/suspensions, enhancing flexibility.
-
Cast Steel Casting: Essential for strict temperature/flow control, operating in high-temp/high-pressure environments to ensure proper molten steel injection. Enables quick task switching for small-batch, multi-variety production.
