Refractory Alumina Carbon material B50 Slide Gate Plate for Steel Molten Melting Flow Control
Product Description
Alumina Carbon B50 Slide Gate Plate
To meet the needs of continuous casting and reducing steelmaking costs for small and medium-sized steel plant, we have developed unburned slide gate series products-unburned Al-C slide plate, which adopts tabular alumina and high pure graphite, adds in proper amount of additive and antioxidant, uses phenolic resin as binder, pressed under press machine. The unburned Al-C plates have the following features: no need to be burned, tar impregnated and distilled, simple processing. This product mainly used in small and medium-sized ladle.

Application:
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: During the refining and transfer of molten steel, the ladle is a core container. The refractory sliding plate is installed at the bottom of the ladle to precisely control the outflow of molten steel. For example, after the molten steel is tapped from the converter, it is poured into the ladle, and at this time, the sliding plate is in the closed state to prevent the leakage of molten steel. When the ladle arrives at the refining station or the casting station, the sliding plate is opened through mechanical or hydraulic devices, allowing the molten steel to be injected into the next process equipment, such as a refining furnace or a continuous casting tundish, at a predetermined flow rate and volume. Its advantages lie in enabling multiple opening and closing operations to meet the complex process rhythm requirements in steel production, effectively reducing secondary oxidation of the molten steel, improving the purity of the molten steel, and thus enhancing the quality of steel products.
Tundishes: As a transitional container for molten steel flowing from the ladle to the mold, the refractory sliding plate in the tundish is also of vital importance. It can flexibly adjust the flow rate of molten steel entering the mold, ensuring the stability of the continuous casting process. During continuous casting, if an abnormal situation occurs in a certain strand of the mold, such as the risk of breakout or quality problems of the cast slab, the corresponding sliding plate can be quickly closed to prevent the molten steel from continuing to flow into the problematic mold, avoiding the expansion of the accident and ensuring the efficient and safe operation of the entire continuous casting production line.
II. Non-ferrous Metal Metallurgy Industry
Copper Smelting: In the smelting and refining of copper, the refractory sliding plate is used to control the flow direction of the copper liquid. For example, between smelting equipment such as reverberatory furnaces and converters and subsequent refining furnaces and casting ladles, the sliding plate serves as a key valve to ensure the smooth transfer of the copper liquid. Since copper liquid has a lower melting point but higher chemical activity compared to molten steel, high requirements are placed on the corrosion resistance and sealing performance of the refractory sliding plate. By using special materials (such as magnesia-chrome, alumina-carbon, etc. combined with optimized formulations), the sliding plate can not only resist the erosion of the copper liquid and its impurities and fluxes on its surface but also maintain good sealing effect at high temperature to prevent copper liquid leakage, ensuring the continuity of the copper smelting process and the quality of the product.
Aluminum Electrolysis: Although the aluminum electrolytic cell itself does not directly use the sliding plate, the refractory sliding plate is widely used in the subsequent refining, transfer, and casting processes of the aluminum liquid. After the aluminum liquid collected from the electrolytic cell enters the refining furnace for purification, it is controlled by the sliding plate to flow into the molds of the casting machine to produce aluminum ingots or aluminum profile billets. At this time, the sliding plate needs to adapt to the low viscosity characteristics of the aluminum liquid to ensure smooth opening and closing and precise control of the aluminum liquid flow, facilitating the efficient operation of the front-end links of the aluminum processing industry and improving the production efficiency of aluminum products.
III. Casting Industry
Cast Iron Casting: In the production process of cast iron parts, the refractory sliding plate installed at the bottom of the casting ladle is responsible for controlling the pouring process of molten iron into sand molds or metal molds. When the molten iron is melted up to the standard, the operator opens the sliding plate to make the molten iron flow evenly and stably into the mold cavity, avoiding casting defects such as pores and cold shuts caused by too fast or too slow flow rate. Moreover, in the same casting batch, if it is necessary to change the mold or suspend casting, the sliding plate can quickly close, allowing for convenient and rapid adjustment of the casting rhythm, enhancing the flexibility and controllability of the casting operation.
Cast Steel Casting: The cast steel casting process has more stringent requirements for temperature and flow control, and the refractory sliding plate is even more essential. Due to the high melting point and relatively poor fluidity of cast steel, the sliding plate needs to work accurately in a high-temperature and high-pressure environment. On the one hand, it ensures that the molten steel is injected into the mold at an appropriate flow rate, enabling the cast steel part to obtain a good forming effect. On the other hand, in the production of multi-variety and small-batch cast steel, it can quickly switch casting tasks to meet different mold sizes and molten steel requirements, providing strong support for cast steel enterprises to meet diverse market requirements.
Refractory sliding plates, with their outstanding high-temperature resistance, corrosion resistance, wear resistance, and reliable opening and closing control performance, run through various high-temperature liquid metal treatment processes and become a key guarantee for the stable and efficient production of modern high-temperature industries. And with the continuous progress of technology, their application prospects will be even broader.
