The reservoir area, as an important hub of logistics connection and production rhythm control in the steel production process, is the foundation of unmanned and intelligent construction of steel mills, while the vehicle is the most important execution unit in the reservoir area. To realize its unmanned operation and intelligent scheduling is a key part of the intelligent manufacturing of the whole process of steel mills.
Rizhao Iron and Steel is an important production base of high-quality thin and wide strip steel in China, as well as the world's largest ESP production base. In recent years, Rizhao Steel in high-end, intelligent, green continuous efforts to speed up the industry's largest 20 million tons of full-process intelligent manufacturing demonstration factory, steel coil reservoir storage and transportation as an important part of the whole process of production process linkage, improve its operation efficiency has become a top priority.
To this end, Rizhao Steel works with SCIYON to carry out intelligent and unmanned storage transformation of ESP finished product warehouse and cold rolled raw material warehouse, accelerate digital enabling efficiency and drive the transformation and upgrading of intelligent manufacturing in the whole process.
The transformation fully combines the current production situation of Rizhao Iron and Steel, aiming at the operational characteristics of ESP finished product warehouse and cold rolled raw material warehouse and the difficulties of "unmanned" transformation, based on the integration and application of independent technologies such as accurate positioning, three-dimensional scanning and electronic anti-roll, the automatic and unmanned operation of 35 vehicles in 10 reservoir areas of Rizhao Steel is realized. The operation efficiency and management level of the reservoir area are greatly improved.
ESP finished product warehouse: high temperature automatic clamp
ESP finished product warehouse is responsible for rolling off the hot rolled steel coil, inventory sorting, repair, train and car delivery. Because the advanced technology of headless rolling has the characteristics of fast rolling speed, high production efficiency and strict stability requirements, in order to meet the turnover demand of steel coils in the condition of high inventory of 5 ESP rolling lines, higher requirements are put forward for the operation performance and efficiency of unmanned vehicles in the reservoir area. During the transformation process, for the ESP high temperature scenario, SCIYON innovated and developed a high temperature automatic clamp solution, which solved the industry problem of clamp sensor application in high temperature environment, and realized the unmanned operation of steel coil handling in 5 reservoir areas more efficient, more stable and safer.
Cold rolling raw material warehouse: multi-vehicle efficient collaboration
As a raw material warehouse for cold rolling production, cold rolling raw material warehouse supplies 9 cold rolling units in 5 reservoir areas through trains, automobiles, over span vehicles, trolley cars and over span walking beams. The steel coil transport vehicles are complex and diverse, with the characteristics of multiple single span vehicles, cross operation, fast production rhythm and high accuracy of loading saddle, which requires more comprehensive coordination and accuracy of unmanned vehicle operation in the reservoir area. To this end, SCIYON and Rizhao Iron and Steel give full play to the professional advantages of both sides to carry out collaborative cooperation, based on the developed WMS reservoir area management technology, the cold rolling raw material warehouse 5 reservoir areas of 20 vehicles intelligent transformation, the transformation covers a maximum of 6 vehicles in a single span, under the premise of ensuring safe operation, through the global scheduling model, Realized multi-vehicle and multi-service synchronous linkage, task priority dynamic management, as well as idle automatic material preparation, automatic storage and other functions, greatly improving the efficiency of collaborative work in the reservoir area.
After the transformation of the reservoir area through the unmanned vehicle operation, further optimize the post structure, greatly reduce the labor intensity of operators, reduce the safety risk of on-site operation; At the same time, the operation of the equipment does not rely on lighting, which effectively saves energy; Accurate handling effectively reduces the damage of steel coil, and the accuracy rate of steel product information reaches more than 99.9%. Under the premise of ensuring safe production, higher efficiency and more refined reservoir area management have been realized, and the application benefits are remarkable.
At present, SCIYON unmanned vehicle solution has been successfully applied in slab and coil reservoir areas of hot rolling and cold rolling steel making process, as well as water slag driving, coal injection workshop, carbon roasting and stacking reservoir area, etc., and has been selected into the recommended catalogue of intelligent manufacturing solutions in the steel industry, the "first version" software in key areas of Jiangsu Province, and won the Golden Bridge Award Excellent Project Award. The program has significant landing benefits and continuous industry recognition.
In the future, SCIYON will continue to focus on the whole process of steel business, jointly expand new scenarios of technology application with steel enterprises, and promote the high-quality development of enterprises to a new level.
