📌 What is the reason for stopper rise and stopper wash in tundish during continuous casting of steel? During continuous casting of steel, the stopper rise and stopper wash in the tundish can impact the casting process. Let’s explore these phenomena: 👉 Stopper Rise: Definition: Stopper rise refers to the upward movement of the tundish stopper rod during casting. 👉 Cause: The difference in thermal expansion between the body material and the metallic rod leads to the connection eventually slackening. During preheating and use, the thin graphite seal provides limited elasticity, and leaks may occur due to vibration and lateral stopper movement. 👉 Impact: Stopper rise affects the flow control of molten steel from the tundish to the mold. It can lead to variations in steel flow rates and affect the quality of the cast product. 📌 Stopper Wash: Definition: Stopper wash occurs when inclusions or impurities deposit on the tundish stopper nose during casting. 📌 Cause: As the molten steel flows through the channel between the stopper rod and the outlet, inclusions deposit on the outlet surface, narrowing the channe. 📌 Impact: Stopper wash can reduce the effective flow area, affecting the steel flow rate and potentially leading to defects in the cast product. #SteelMaking #Manufacturing #Metallurgy #MetallurgicalEngineering #tundishcar

Advantages of Carbide Tipped Bandsaw Blades 🎈1. Longer Life: The carbide tips offer superior wear resistance, resulting in a significantly longer blade life compared to traditional high-speed steel blades. 🎈2. Increased Cutting Speed: The hardness of carbide allows for higher cutting speeds and feed rates, improving productivity. 🎈3. Improved Cutting Quality: Carbide tips produce cleaner cuts with less burring and chipping, enhancing the overall finish of the workpiece. 🎈4. Versatility: Carbide tipped blades can handle a wide range of materials and applications. 🎈5. Cost-Effective: While the initial cost might be higher, the extended blade life and increased productivity often lead to lower overall costs per cut. #carbidetippedbandsawblade #carbidebands #alloyblade #weldalloyhead #woodworking #carbidebandsaw #carbideblade #bandsaw #bandsawblade #sawblade #carbidetipped #brazewelding #sawmill #D6A #75Ni8 #alloybandsaw #woodcutting #woodshop #tungstencarbidetipped #stelliteblade #woodcutting #woodworker #lumbercutting #oakcutting #maplecutting #bladewelding #timbercutting #grindingwheel #sharpeningstone #industrialtools

Slag is a byproduct of the cupola furnace process, and it is a mixture of impurities that rise to the surface of the molten metal during the melting process. The slag is typically less dense than the molten metal and floats on top of the metal. To prevent this from happening, furnace operatives use a long pole to break up any solidified slag that may have accumulated at the bottom of the furnace. However, some slag may settle at the bottom of the furnace and solidify into a hard mass. This can block the flow of molten metal and prevent the furnace from operating properly. They insert the pole through the slag hole, which is a small opening located at the bottom of the furnace, and use it to break up the slag into smaller pieces that can be easily removed. This ensures that the flow of molten metal is not obstructed and that the furnace can operate efficiently. #foundry #castiron #howitworks #manufacturing #processes #fire #metalwork #furnace

The immersed water inlet is located between the tundish and the crystallizer. During continuous casting operation, put the lower nozzle on top of the upper nozzle. ①Prevent secondary oxidation and nitridation of molten steel and splashing of molten steel; ②Adjust the flow state and injection speed of molten steel; ③Prevent non-metallic inclusions in the mold slag from being involved in the molten steel, and play an important role in promoting the floating of inclusions in the molten steel; ④Has a decisive influence on the continuous casting billet yield and billet quality. Materials and development of immersed nozzles: Al₂O₃-C/ZrO₂-C composite nozzle Since ZrO2 has excellent chemical stability, it is difficult to be corroded by CaO-Al₂O₃-SiO₂ series protective slag. ZrO2 melted into the slag at high temperatures enhances the viscosity of the slag. The unmelted ZrO₂ particles increase the apparent viscosity of the slag, thereby reducing the erosion of the ZrO₂-C slag layer by the protective slag and improving the durability of the nozzle. Common problem: Al₂O₃ blockage Solution: blow argon, improve materials, change the shape of the nozzle, improve the cleanliness of molten steel, etc. Get more refractories info and solution,contact Lianxin team: 📞 WA:+86 15838386016 📩 Email:lianxingaowen@gmail.com #refractory #bricks #castable #ramming #clay #silica #alumina #magnesia #import #cement #glass #nonferrous #export #hightemperature #metal #materials #foundry #furnace #kiln #scarp

Grade - The word "Grade" refers to the pipe grade. This is a value is entered in Pipe information Report for the connection in question. Pipe Grade is defined as the strength and hardness of the of the pipe material. Companies identify pipe grades by stenciling the tube body with a color coat band and color coating the pipe couplings. Example: N-80 grade material the couplings is painted red, J-55 grade material the couplings are painted green, P 110 grade material the couplings are painted white. Special alloy material are also rated the same way, but with the acronym to for alloy concentration for example: SM 2250-110KSt which translates as SM for Sumitoro as the manufacturer, 22 for 22% chrome allay and 50% for 50 percent of the material being nickel and finally the 110KSI for the strength of the material.

Wondering about the variances between galvanized iron wire and stainless steel wire? Here are the key distinctions: - **Galvanized Wire Characteristics**: Known for its toughness, elasticity, and maximum zinc coating of up to 300 grams/square meter. With thick zinc coating and strong corrosion resistance, it finds applications in construction, handicrafts, woven wire mesh, highway guardrails, product packaging, and daily civilian use. - **Types of Galvanized Wire**: It's categorized into hot-dip galvanized wire and cold-dip galvanized wire. Hot-dip galvanizing involves immersion plating in heated molten zinc liquid, offering strong corrosion resistance. On the other hand, cold galvanizing gradually plates zinc on the metal surface through electroplating, with lower production costs. - **Stainless Steel Material**: Resistant to weak corrosive media like air, steam, water, and chemically corrosive media such as acids, alkalis, and salts. Stainless steel wire drawing is a prevalent surface treatment technology in the industry, providing a wire drawing effect for stainless steel and aluminum products. Understanding these distinctions is crucial for selecting the right material for your specific applications. #GalvanizedWire #StainlessSteelWire #MetalIndustry #SurfaceTreatmentTechnology
