Efficient Flow Control FL6300 Ladle Slide Gate Plate for Steelmaking Product Description Slide Gate Plate has various range of formulas including Alumina Carbon,Alumina Zirconia Carbon,Magnesia Spinel and so on to suit different steelmaking conditions to achive best service life.SNREF Slide Gate Plate adopts High quality bauxite material , also takes tabular alumina, carbonaceous material and zirconia-containing material as main raw materials, adds in high performance antioxidants, uses phenolic resin as binder, formed under high-pressure and burned under high temperature.The slide plates have the advantages of high strength, good erosion resistance, thermal shock resistance and good stability etc., mainly used in large and medium-sized ladle. ​ Optimize the Refractory Performance:Alumina magnesia spinel has a high melting point, excellent thermal stability, and good mechanical strength. It can maintain a stable structure at high temperatures, enhancing the refractoriness and load softening temperature of refractory materials used in steelmaking. This enables the refractory materials to better withstand the hydrostatic pressure of molten steel and the effect of high temperatures.   Reduce the Thermal Conductivity:With a relatively low thermal conductivity, it can reduce the heat loss during the steelmaking process, playing an excellent role in heat insulation and thermal preservation. This is beneficial for reducing energy consumption and improving the efficiency of steelmaking.   Inhibit the Penetration of Molten Steel:Alumina magnesia spinel can effectively prevent molten steel and furnace slag from penetrating into the interior of refractory materials, avoiding the structural damage and performance degradation of the materials caused by penetration. As a result, it can extend the service life of refractory materials and reduce production costs.

4200 Refractories Slide Gate Plate for Ladle Sliding Systems  Product Description The 4200 Ladle Slide Gate is a high - performance refractory product designed to meet the demanding requirements of the metallurgical industry, especially in steelmaking processes. This slide gate plays a crucial role in controlling the flow of molten steel in ladles, ensuring efficient and precise casting operations.     Exceptional Thermal Shock Resistance: The 4200 Ladle Slide Gate is engineered with advanced refractory materials that can withstand rapid temperature changes during the ladle - to - casting process. This property prevents cracking and spalling, significantly extending the lifespan of the slide gate. For example, in continuous casting operations where the temperature of molten steel can vary rapidly, the slide gate maintains its structural integrity.     High Strength at Elevated Temperatures: It exhibits remarkable strength even at extremely high temperatures, which is essential for withstanding the pressure and force exerted by the molten steel. This high - temperature strength ensures that the slide gate does not deform or break under the harsh conditions of steelmaking, guaranteeing reliable and safe operation.     Excellent Erosion Resistance: The slide gate is highly resistant to erosion caused by the high - velocity flow of molten steel and slag. Its refractory composition is carefully formulated to minimize wear and tear, reducing the need for frequent replacements. In steel mills where ladles are used for multiple casting cycles, the 4200 Ladle Slide Gate's erosion resistance helps to maintain consistent performance over an extended period.     Low Friction Sliding Surface: The sliding surface of the gate is designed to have a low roughness and friction coefficient. This feature allows for smooth and precise control of the molten steel flow, enabling operators to adjust the flow rate accurately. As a result, it improves the quality of the cast steel products by ensuring a stable and consistent flow of molten metal.   Application Our 4200 Ladle Slide Gate is manufactured under strict quality control measures. Each product undergoes rigorous testing to ensure compliance with international quality standards. From the selection of raw materials to the final inspection, every step of the production process is carefully monitored to deliver a reliable and high - quality product to our customers.In conclusion, the 4200 Ladle Slide Gate offers a combination of outstanding performance, durability, and reliability, making it the preferred choice for metallurgical applications. Whether you are in the steelmaking, foundry, or other related industries, our slide gate can enhance the efficiency and quality of your operations. ​ Detailed Photos ​​​ Packaging & Shipping ​​​​ Product Parameters      Item Al2O3 SiO2 ZrO2 CaO C 1 FT160 Upper Plate  75 8.5 10   6.5 2 FT160 Middle Plate  75 8.5 10   6.5 3 FT160 Lower Plate  75 8.5 10   6.5 Collector Nozzle 96 1   1.5   Company Profile Shandong Sinorefractory New Materials Co.,Ltd (SinoRefractory)has been focusing on international marketing of flow control refractories in iron and steel industry for 17 years.SinoRefractory is the second generation of refractories export enterprise developed out of EMEI Group.Supported by one of China's largest production bases in functional refractory materials.Through years of development in the field of exporting top quality refractories to worldwide markets,SinoRefractory aims at researching,producing,marketing and exporting high standard Ladle slide gate plate,Ladle Nozzles,Well blocks,Purging plugs,Nozzle stuffing sand,Refractory castables, Slide gate Mechanisms etc.Up to now,SinoRefractory has supplied high quality refractory products and services to nearly 70 top-hundred global steel enterprises.SinoRefractory will always put clients'interest in the first place,striving to provide a wide range of services,including technical solution,pre-sales support,after-sales services,installation team support,professional know-how according to the changing of steelmaking condition,etc.We are not only selling products,we are more focused on supporting,developing and growing together with clients.​ FAQ Below are some FAQ and answers about ladle and tundish flow control refractories:Q: What are the requirements for refractories for ladle?A: The requirements of refractories for ladle mainly include:  * high temperature resistance * thermal shock resistance * resistance to the erosion of the slag * high temperature with sufficient mechanical strength * the lining has a certain degree of expansionQ:What are the reasons for the destruction of refractories for ladle?A: The main causes of damage are as follows:When the ladle transports high-temperature molten steel, the high-temperature molten steel and slag at about 1680ºC scour and erode it, especially in the slag line part, the scouring and erosion is more serious, and it is an important factor to decide the service life of the ladle.LF and other extra-oven refining treatment on the unburnt brick damage is serious.Q:What steel grades are different materials of slide plate bricks suitable for respectively?A: Different materials of slide plate bricks are applicable to different steel grades.
