The mystery and charm of the pulverized coal lance.
In the process of steel production, the excellent application of the PQ type pulverized coal lance highlights its powerful function. This lance has a simple structure, is convenient to operate, and is specially designed for combined use with a ball valve. In the blast furnace for ironmaking, it plays an indispensable role.
I. In-depth Interpretation of Process Characteristics
The lance body made of 2520 heat-resistant steel is not only sturdy and durable but also has high-temperature resistance. What is more remarkable is the advanced technology of "local ceramic lining on the inner wall of the steel pipe" in the lance. The application of this technology not only extends the service life of the lance but also plays a key role in the process of pulverized coal injection.
II. Demonstration of Usage Characteristics and Advantages
The service life of this lance is astonishingly long. Its low replacement rate greatly reduces the labor intensity of workers, and the stability of the lance position effectively reduces the number of blast furnace shutdowns, thereby improving production efficiency. More importantly, it can stably increase the amount of pulverized coal injection and achieve large-scale injection, which undoubtedly provides strong support for reducing ironmaking costs. In addition, its repairability also extends the overall service life of the lance, making this investment more valuable.
The PQ-2000 blast furnace pulverized coal lance is like a dancer in the ironmaking industry, dancing gracefully in the blast furnace. It is skillfully composed of parts such as the pulverized coal lance tube, lance head outer sleeve, porous lance head, and lance head cover, and each part plays a crucial role. Especially the porous lance head, with evenly distributed round holes, skillfully divides the pulverized coal airflow into several small streams. These streams quickly mix with the hot blast of the blast furnace, enabling the pulverized coal to burn fully and greatly improving the utilization rate of pulverized coal.
In actual operation, this lance, like a skilled dancer, is lightly inserted into the furnace body from the end with a bayonet and starts its work. When the blast furnace needs to inject pulverized coal, it quickly and accurately ejects pulverized coal to meet the production needs of the blast furnace. When the blast furnace stops pulverized coal injection, the ball of the ball valve will automatically reset, preventing the high-temperature gas in the furnace from leaking out and ensuring production safety.
Although the PQ type pulverized coal lance has high reliability and stability, we still need to remain vigilant in the face of emergencies. Although its working principle and structure are complex, regular inspection and maintenance are the keys to ensuring its normal operation. This is like taking careful care of a dancer; only when every part is in the best condition can it continue to show its unique charm in the blast furnace.
In general, the PQ type pulverized coal lance brings great convenience and benefits to the ironmaking industry with its unique process characteristics and excellent usage characteristics. It is not only a capable assistant of the blast furnace but also a reliable tool for us to pursue safe production.
