Recently, TSIC’s EPC general contracting project-the raw material area of the Tang Steel New District of HBIS Group was completed and put into operation. The raw material unloading, storage, mixing, output and other systems are operating stably, and the environmental protection standards have achieved the most stringent 'Tangshan City Ultra-low Emission Standard' and even reduce by 10%, and at the same time create a precedent for the industry's fully intelligent material yard.

HBIS Group Tang Steel New District

Panorama of Raw Material Area

China's iron and steel industry has gradually entered a period of high-quality development. 'More economical, more environmentally friendly, smarter, and more efficient' is the core concept that TSIC has integrated in the planning and construction of the Tang Steel New District. As the most upstream process of production in the new area, the raw material yard has a compact layout and smooth logistics. Through the use of a series of cutting-edge processes and advanced technologies, its comprehensive advantages such as large-scale, high-efficiency, economical, green, digital, and intelligent Second to none in the world.

More Economical and Environmentally Friendly

Integrated Logistics Transportation Technology

Port-Stockyard Material Conveying Corridor

The project makes full use of the advantages of Tang Steel New Area adjacent to the Tangshan Port wharf. The front port and the rear factory are directly taken by ships. The materials are directly transported to the stockyard for storage without landing at the wharf, realizing the seamless connection and integration of management and control between the wharf and the stockyard High-efficiency operation greatly improves the efficiency of material transportation, saves logistics transportation costs, and reduces material loss and pollution. Only the port charges can create about 300 million yuan in profits for enterprises every year.

Long-distance, Large-capacity Pipe Belt Conveyor Technology

In order to avoid economic losses and environmental pollution caused by materials falling during transportation, and to reduce the adverse effects of the external environment such as site and weather on material transportation, the project adopts green environmental protection equipment-long-distance, large-capacity pipe conveyor. The total transportation distance of raw fuel is about 16 kilometers. Through the curved arrangement of the pipe belt machine and the simultaneous conveying of the upper and lower pipe belts, it can effectively save the floor space, reduce the transfer and dust points, and realize energy saving, consumption reduction and clean production.

Mixing Stockyard Technology

Mixing Yard

The mixing stock yard of this project implements the one-pile two-extraction system, equipped with a mixing stacker and a drum mixing reclaimer. The stacking and reclaiming capacity are the highest in China, and it adopts intelligent unmanned operation and precise operation. Many advanced technologies such as positioning, automatic dust sensing intelligent spray system, automatic scanning of stockpiles and three-dimensional imaging.

C-type stock yard, Circular Stock Yard and Silo Storage Technology

C-type Stock Yard

Type C stockyard has outstanding advantages in environmental protection, energy saving and consumption reduction. It is equipped with large-scale material transportation equipment a half-door scraper reclaimer. The equipment is safe and environmentally friendly, and its input and output capabilities are the best in China.

Circular Stock Yard

Concentrate powder and coal powder are stored in a circular stockyard. The upper structure of the stockyard is in the form of a single-layer spherical reticulated shell, which has the advantages of good environmental protection effect and large unit storage.

Silo Storage

The flux storage adopts the silo group technology, which improves the utilization rate of land resources on the one hand. On the other hand, the silo can directly implement ingredients while storing materials, which greatly simplifies the process and saves costs.

Smarter and more Efficient

The construction of the raw material yard in Tang Steel New Area aims to 'build the first fully intelligent yard in the steel industry'. The design runs through the concept of intelligent control and intelligent perception. Through the integrated application of advanced technologies such as 3D laser simulation model, full tracking of raw materials, intelligent scheduling of operation plans, and seamless connection of inspection and testing systems. A smart production management and control system was formed, which successfully achieved high-efficiency transportation, unmanned operations, digital storage, and refined management.

Intelligent Scheduling Technology.

Intelligent Scheduling Framework Diagram

After intelligently receiving raw material procurement, production planning and other information through the MES network and optimizing and decomposing them, the stockyard operation instructions are formed, and the reverse transportation control of the path optimization of the incoming and outgoing materials is performed, and the unmanned stacking and reclaiming operation control of the optimization of the storage area. It can realize the optimal storage space, energy consumption, and equipment utilization, and can feed back the operating status of the stockyard equipment and storage information to the network at all levels in the new area in real time

Unmanned Technology of Stacker-reclaimer.

Data Flow Chart of Intelligent Stockyard

Various types of stackers and reclaimers are seamlessly integrated into the operation planning process. Through large-scale equipment precise positioning technology and model optimization calculations, real-time control of the stacker and reclaimer's movements, pitching, and rotation, passes through the remote centralized control center The monitoring terminal tracks on-site operations and realizes the unmanned and fully intelligent operation of the stacker and reclaimer.

Intelligent Mixing Technology

According to the requirements of the ratio of iron, magnesium, sulfur, phosphorus and other indicators in the mixed ore, the AI algorithm is used to calculate the cost-optimized batching, and the mixed batching system performs accurate batching operations based on the calculation results. Afterwards, according to the actual operation performance and the material inspection situation of the mixing pile, combined with the mixing unmanned large machine control model, the formula is optimized and adjusted, and finally the mixing pile composition is more uniform, and the stacking and reclaiming is more accurate.

Belt Intelligent Protection Technology

By installing an addressing coding system for the belt conveyor, a complete intelligent diagnosis protection system is formed, and various faults of long belts can be intelligently detected, diagnosed and solved remotely, which can reduce the configuration of inspection personnel and quickly eliminate hidden production hazards.

The application of new technology and new technology has given the raw material field of HBIS Tang steel New Area many advantages such as economy, environmental protection, intelligence and high efficiency, ensuring long-term, safe and stable continuous supply of raw materials, and will create good economic benefits for Tang steel New Area And social benefits.
