Qin Ye Group: Green + Intelligent Metallurgical Vehicles Boost High-End Development in the Steel Industry
Qin Ye Group is committed to promoting the quality upgrade of domestically produced equipment through technological innovation, meeting the expectations of steel enterprises for excellent equipment, driving the renewal of metallurgical equipment, providing high-quality equipment products and excellent services across multiple fields for steel enterprises, and assisting in the green, low-carbon, intelligent, and high-quality development of smelting processes, contributing to the strength of Made in China.
On the date, at the 5th meeting of the 2nd session of the Metallurgical Equipment Branch of the China Iron and Steel Industry Association, Hao Xiaojing, Chief Engineer of Qinye Group, introduced the application scenarios and characteristics of green and smart metallurgical vehicles such as new energy transport vehicles, intelligent pouring cars, and new torpedo ladle preheaters, as well as key smelting process and equipment upgrade cases.
Regarding new energy transport vehicles, Hao Xiaojing introduced that these vehicles have a wide range of applications, primarily in the transportation of molten iron at the steel-iron interface. New energy transport vehicles use supercapacitors/battery on-board energy storage components as power sources, freeing traditional transport vehicles from the constraints of cable reels, tow cables, sliding power lines, and locomotive traction, making transportation more flexible and efficient. They can achieve online rapid automatic charging, allowing for battery replenishment during standby periods, suitable for various equipment operating under intermittent duty cycles, especially in long-distance transport scenarios. Additionally, new energy transport vehicles can be equipped with devices such as cover opening/closing mechanisms, automatic power connection devices, weighing devices, automatic control systems, and remote operating systems. Qinye's technological reserves are not limited to molten iron transport (mixing ladles and open-top ladles); other materials such as molten steel, scrap steel, steel coils, and steel billets can also be transported using new energy vehicles with broad and standard gauge tracks.
It is worth noting that currently, Qin Ye Group's new energy transport vehicles employ an intelligent control system, which achieves precise positioning through advanced control technologies such as DC input frequency converters, laser ranging + (RFID), and more. The vehicles also utilize an intelligent perception system to determine obstacles and ensure safe autonomous driving. Advanced communication technologies, including industrial wireless networks, are employed to establish redundant communication, enabling precise and reliable control of molten iron transport vehicles. Additionally, these new energy vehicles can be integrated into the iron-steel interface management system, facilitating remote and intelligent management.
Regarding the intelligent ladle car, Hao Xiaojing introduced that the primary application field of the intelligent ladle car is the special steel industry that uses the bottom pouring method for ingot casting production. It is used for producing various types of alloy steels, non-alloy special alloys, as well as various forged and rolled steel ingots. Qin Ye can provide mature overall solutions, making the pouring process more convenient, optimizing the technology to ensure the quality and production efficiency of steel ingots, and increasing the user's yield.
Currently, the intelligent ladle car has achieved automatic positioning of the tundish pouring spout, automatic pouring according to the set pouring curve, and can also perform intelligent temperature measurement and sampling. It automatically cleans the nozzle when it is not smooth by burning oxygen, and automatically adds insulation covering material. Moreover, in response to environmental protection requirements, the intelligent ladle car can be equipped with a vehicle-mounted dust removal system. The ladle car vehicle-mounted dust removal system developed by Qin Ye based on actual customer needs addresses the pain points of customer production sites, promotes environmental protection upgrades for enterprises, ensures compliance in production, reduces dust emissions, and improves the operating environment. Qin Ye not only provides intelligent ladle car equipment but also assists customers in building intelligent mold casting workshops, achieving automatic mold transportation, automatic pouring, automatic mold separation and solidification, mold removal and transfer, cleaning, and stacking.
In addition to new energy transportation vehicles and intelligent steel pouring cars, Hao Xiaojing introduced that Qinye Heavy Industry has also developed a smart energy-saving baking device—the new torpedo ladle burner. The new torpedo ladle burner can achieve energy savings of %~%, helping user enterprises save energy and reduce consumption; it enables precise temperature control and one-button unattended operation with dual parallel circuits, and is equipped with multiple safety interlocks for safe and reliable operation; during operation, it generates fewer nitrogen oxides, making it low-carbon, environmentally friendly, and pollution-free.
In the field of metallurgical new technologies, Qin Ye Group offers technical upgrades and transformation solutions for key smelting processes and equipment in the iron and steelmaking processes, aiming to create benefits for customers through energy saving and emission reduction. Hao Xiaojing primarily introduced the desulfurization process and equipment, as well as the new converter dephosphorization process and equipment of Qin Ye Group. The desulfurization process and equipment feature a new type of stirring impeller structure, high stirring speed, reduced operation time; spring structure for stable operation; low accident rate and less maintenance work; high-speed operation, reducing the amount of desulfurizing agent used. It has been implemented at Baosteel. The new converter dephosphorization process and equipment allow for desulfurization within the converter, reducing the use of calcium oxide by at least % compared to other processes, and producing less slag. Currently, this technology has been adopted by Japanese steel enterprises.
