Stabilizing and Enhancing the Pulverized Coal Injection Process: A New Chapter in Blast Furnace Ironmaking
In the realm of ironmaking processes, stabilizing and increasing the pulverized coal injection rate has become a crucial path to reducing the cost of blast furnace ironmaking. The introduced 2520 heat-resistant steel, wear-resistant, high-temperature blast furnace pulverized coal ceramic lance, like a solid sharp sword, not only significantly extends the service life of the lance but also provides a solid guarantee for protecting the tuyeres and reducing blast furnace downtime. This "sharp sword" plays a pivotal role in the fields of high blast furnace temperature, oxygen enrichment, and large-scale injection.

I. The Craftsmanship Soul of the Pulverized Coal Lance
The lance body made of 2520 heat-resistant steel is like an ancient sword, being not only sturdy but also durable, capable of withstanding high-temperature tests. The innovation inside the lance is the icing on the cake – the advanced local ceramic lining technology on the inner wall of the steel pipe, which elevates the performance of this "sword" to a higher level, just like a legendary weapon.

II. The Operational Charm of the Pulverized Coal Lance
1. The extension of service life, like the accumulation of years, reduces the replacement rate and eases the labor intensity of workers, playing a triumphant melody of efficiency.
2. The stable lance position, like a calm and composed general, reduces the "drums of war" caused by blast furnace downtime, thereby accelerating the production rhythm.
3. By stabilizing and increasing the pulverized coal injection rate, the tactic of large-scale injection is realized, which is like a wise move, effectively reducing the cost of ironmaking and composing a chapter of economic benefits for the enterprise.
4. The repairability of the pulverized coal lance, like a well-preserved old sword, fully demonstrates the maximization of resource utilization.
The PQ-2000 blast furnace pulverized coal lance dances gracefully in the blast furnace like a dancer. Its structure is simple and elegant, and operation is convenient and smooth. This lance is composed of components such as the pulverized coal injection pipe, lance head outer sleeve, porous lance head, and lance head cover, which are harmoniously combined. Its unique design lies in the porous lance head installed at the head of the pulverized coal injection pipe, with evenly distributed round holes, which divides the pulverized coal airflow into multiple streams and mixes it quickly with the blast furnace hot air, allowing the pulverized coal to burn fully. This not only improves the utilization rate of pulverized coal but also adds a strong touch to the green development of the enterprise.

On the production site, this lance is inserted from the end with a bayonet like a swimming dragon, moving gracefully inside the furnace body. When the blast furnace needs pulverized coal injection, it sprays pulverized coal quickly and accurately like a divine help. When the blast furnace stops pulverized coal injection, the ball valve automatically resets like a guard, effectively preventing the overflow of high-temperature gas and ensuring production safety. Although the pulverized coal lance has extremely high stability and reliability, to cope with possible challenges, regular inspection and maintenance are still essential, ensuring that it operates stably on the production line for a long time.
This series of optimizations and improvements is like a magnificent symphony, bringing revolutionary changes to the blast furnace ironmaking industry. It not only enhances the melody of production efficiency but also composes a larger chapter of economic benefits for the enterprise.
