中工耐中间包冲击板：铸就炼钢领域的品质标杆SIR Tundish Impact Plate: Setting a Quality Benchmark in the Steel making Industry

中间包冲击板：炼钢工序的关键守护者

Tundish impact plate: a key guardian of the steelmaking process

在现代钢铁冶炼工艺中，中间包作为连接钢包和结晶器的核心过渡装置，承担着钢水分配、净化和稳定流场的重要职责。而中间包冲击板则是中间包内部最关键的部件之一，它直接承受着钢水注入时的高速冲击和高温侵蚀，其性能优劣对中间包的使用寿命、钢水纯净度以及连铸生产的稳定性都有着决定性影响。
传统的中间包冲击板往往存在抗冲刷能力不足、热震稳定性差、使用寿命短等问题，频繁的更换不仅增加了钢铁企业的生产成本，还会导致生产中断，影响生产效率。因此，研发和应用高性能的中间包冲击板成为钢铁行业提升品质、降本增效的关键需求。

In modern steelmaking processes, the tundish, as a core transitional device connecting the ladle and the crystallizer, plays a crucial role in steel distribution, purification, and stabilizing the flow field. The tundish impact plate is one of the most critical components inside the tundish, directly enduring the high-speed impact and high-temperature erosion during molten steel injection. Its performance has a decisive impact on the tundish's service life, the purity of the molten steel, and the stability of continuous casting production.

Traditional tundish impact plates often suffer from insufficient erosion resistance, poor thermal shock stability, and short service life. Frequent replacements not only increase production costs for steel companies but also lead to production interruptions and affect efficiency. Therefore, the research and application of high-performance tundish impact plates has become a key requirement for the steel industry to improve quality, reduce costs, and increase efficiency.

SIR Tundish Impact Plates: Superior Performance Creates Industry Advantages

1. Superior Erosion Resistance, Extended Service Life
Hongda Furnace Industry's tundish impact plates utilize silicon carbide corundum composite material, achieving an erosion resistance index of 15-20 times/thousand tons of molten steel, more than twice that of traditional mullite materials. This excellent erosion resistance allows the impact plates to withstand the high-speed impact and long-term erosion during molten steel injection, effectively extending the tundish's service life and reducing production interruptions and maintenance costs caused by impact plate damage.

2. Excellent Thermal Shock Stability, Adaptable to Complex Operating Conditions
Tundishes undergo frequent heating and cooling processes during operation, placing high demands on the thermal shock stability of the impact plates. Hongda Furnace Industry's tundish impact plates, employing a unique formula and advanced production processes, possess outstanding thermal shock stability. They maintain structural integrity under drastic temperature changes, effectively resisting cracking and spalling caused by thermal shock, ensuring stable tundish operation.

3. Superior Slag Erosion Resistance, Ensuring Steel Purity

During the steelmaking process, molten steel carries a large amount of slag, which severely corrodes the tundish impact plates. Hongda Furnace Industry's tundish impact plates utilize high-quality refractory aggregates and binders. Through a rational material ratio and microstructure design, the products possess superior slag erosion resistance, effectively blocking slag penetration and erosion, reducing inclusion content in the molten steel, and ensuring steel purity and product quality.

4. Customized Services to Meet Diverse Needs
Different steel companies have different steelmaking processes and steel characteristics, resulting in varying performance and specification requirements for tundish impact plates. Hongda Furnace Industry fully considers the personalized needs of its customers, providing customized product design and production services. The company's technical team will tailor the most suitable tundish impact plate solution for each customer based on their specific working conditions and usage requirements, ensuring that the product's performance and dimensions perfectly match the customer's tundish, maximizing the product's advantages.

成功案例：携手钢铁企业共创辉煌
多年来，宏达炉业的中间包冲击板凭借卓越的性能和优质的服务，已经在国内众多大型钢铁企业得到了广泛应用，并获得了客户的一致认可和好评。
例如，与某大型钢铁集团的合作中，该集团原使用的中间包冲击板平均使用寿命仅为12炉次，且频繁出现损坏和剥落现象，严重影响了连铸生产的稳定性。在使用宏达炉业的中间包冲击板后，中间包的平均使用寿命提升至18炉次以上，不仅减少了冲击板的更换频率，降低了生产成本，还显著提高了钢水的纯净度和连铸坯的质量。

Successful Cases: Partnering with Steel Companies for a Brighter Future

For many years, Hongda Furnace Industry's tundish impact plates have been widely used by numerous large steel companies in China, thanks to their superior performance and high-quality service, earning consistent recognition and praise from customers.

For example, in a collaboration with a large steel group, the group's original tundish impact plates had an average service life of only 12 heats, frequently experiencing damage and spalling, severely impacting the stability of continuous casting production. After using Hongda Furnace Industry's tundish impact plates, the average service life of the tundish increased to over 18 heats, not only reducing the frequency of impact plate replacement and lowering production costs, but also significantly improving the purity of molten steel and the quality of continuously cast billets.
