Recently, in the production workshop of Great Wall Cast Steel, a batch of large slag pot cast steel parts, customized for the German SMS group, were neatly arranged, completed and ready for shipment. This batch of slag pots is another delivery batch from the continuous cooperation between Great Wall Cast Steel and SMS Group in recent years, marking that Great Wall Cast Steel's slag pot products have entered the supply chain system of a top international metallurgical equipment brand.

Great Wall Cast Steel exports slag pots to SMS Group in Germany

　　SMS Group is a leading global manufacturer of metallurgical equipment, headquartered in Germany. Its business covers the entire metallurgical process, from ironmaking and steelmaking to rolling, providing equipment and technical services. SMS Group has extremely stringent qualification requirements for its casting suppliers; becoming a long-term partner as a slag pot supplier is itself an authoritative endorsement of a casting company's comprehensive strength.

　　Slag pots are core containers in the metallurgical steelmaking process for receiving, transferring, and tipping high-temperature steel slag. They operate under extremely harsh conditions—directly contacting molten steel slag at temperatures exceeding 1400°C, and enduring repeated thermal shocks, mechanical impacts, and temperature fluctuations. This places extremely high demands on the material and casting quality of the cast steel components.

　　Thermal Fatigue Resistance: The working surface of the slag pot is repeatedly subjected to rapid heating and cooling; the material must possess excellent thermal fatigue resistance to prevent cracking and spalling during use.

　　High-Temperature Strength: Under high-temperature conditions, the casting body must not deform or crack when bearing the weight of the steel slag and the tipping load.

　　Casting Quality: The casting must be dense and uniform internally, eliminating internal defects such as shrinkage porosity and gas bubbles; otherwise, under repeated thermal shock, cracks can easily initiate and propagate from these defects.

　　Truncate Reliability: The trunnion is the only stress point for lifting and tipping the slag pot; the root transition fillet and internal structure quality must ensure long-term reliability.

　　The SMS slag pots produced by Great Wall Cast Steel are manufactured entirely in accordance with the technical standards of the SMS Group in terms of material selection, casting process, heat treatment, and technical inspection, fully demonstrating the company's manufacturing level in the field of metallurgical cast steel slag pots.
