Baotang, China's steel base, has played a new role in green development

At baotou steel group, red-hot billets are rolled and rolled on a line thousands of meters long before being transformed into silver-gray high-speed rails.Outside the factory, lush trees with scattered flowers and plants, as if place yourself in the general landscape.

This is a view of the baotou steel plant today, but not then."The old man in the factory said that the environment of baotou steel plant was very poor in the early stage of construction. When he woke up in the morning, the environment was' covered with quilt and sand '."Said Chen wei, plant capacity greening manager of baotou steel group energy conservation and environmental protection center.

As an important steel production base in China, baotou iron & steel group co., ltd. is holding on to its product competitiveness while adhering to the green development path of energy conservation, environmental protection and elimination of backward production capacity. A new movement of green development is playing in baotou, a grassland steel city in Inner Mongolia.

Steel companies in this prairie city once let "red dragons" roam over the city."In the past, the smoke from open hearth steelmaking contained iron oxide, and the smoke turned red. Baotou residents called it 'red dragon.'""Said zhao guoqing, deputy director of the energy conservation and environmental protection center of baotou steel group.

In recent years, with the continuous upgrading of equipment and technology, baotou steel group has achieved the improvement of product categories, quality and quantity.The development and comprehensive application of environmental protection technologies not only make "red dragon" extinct in the city skyline, but also improve the environment and create hundreds of millions of economic benefits every year.

By the end of 2018, the green coverage rate of baotou steel group reached 46.6%, and "half of the plant is green" became a new name card of baotou steel group.

"Now there are poplars, pecans and poplars planted in the factory. The air in the factory is better, the environment is better, and the workers feel better about going to work."According to Chen wei, planting plants that are resistant to drought and salt can reduce water consumption while greening the factory.

Steel slag is the traditional waste in steel production.How to make use of resources and turn waste into treasure has become another important topic in the green development process of baotou steel group.

"Steel slag has the advantages of high strength, high density and strong wear resistance, which can be used as a high-quality material for road engineering instead of non-renewable natural sand and stone."Clad steel metallurgical slag company (green) technical personnel xiao-li li said, pavement material construction technology of steel slag and conventional pavement materials technology basic same, but the resistance to high temperature stability of asphalt concrete steel slag, water damage resistance is strong, good durability, can prolong the service life of pavement, reduce road maintenance cost, has good economic benefits, social benefits and environmental benefits.

At present, the steel slag technical index of baotou steel group has met the requirements of the national and industrial road slag related indexes. Steel slag is used as the material for the maintenance of several roads in the factory, and the cumulative construction area is more than 500,000 square meters.

"We are committed to promoting the construction of relevant local standards for steel slag paving, and gradually promoting the use of steel slag in municipal roads and high-grade roads."Li xiaoli said.
