The wear-resistant pulverized coal spray gun tube takes advantage of the abrasion resistance, high temperature resistance, corrosion resistance and poor toughness of the new ceramic material and the superalloy material with high strength and high toughness, and the “superalloy ceramic lined pulverized coal spray gun” developed by self-spreading technology can give full play to the strengths of individual materials, overcome the weaknesses of each other, and realize the purpose of improving the life of the pulverized coal spray gun.
The spray gun used in modern blast furnace is mostly welded with ordinary stainless steel seamless steel pipe or high-strength heat-resistant steel pipe, which has a short service life and frequent replacement, large labor intensity of workers, affecting the production of pig iron, increasing the cost of ironmaking, and directly restricting the development of coal injection technology in blast furnaces. In order to extend the service life of the spray gun, 2520 heat-resistant steel pipe is coated with ceramic, wear-resistant and high-temperature resistance, and the blast furnace pulverized coal spray gun adopts gravity separation technology to develop a ceramic wear-resistant and high-temperature blast furnace pulverized coal spray gun, which can increase the service life by 3 to 6 times. I plant services: a moQ, large quantity of concessions, warm service, to ensure quality.
