Recently, Hebei Xinda Iron and Steel Group Co., Ltd. received the green product certification certificate issued by MCC Testing and Certification Co., LTD. Xinda hot-rolled ribbed steel bar, hot-rolled H-beam steel, hot-rolled I-beam steel, carbon structural steel hot-rolled thick steel strip, granulated blast furnace slag powder products were rated as three-star green products.
The company attaches great importance to energy saving and environmental protection, and submitted the initial audit application for "metallurgical green product certification" to MCC Testing and Certification Co., Ltd. in April this year. The green Product certification expert group evaluated a number of environmental protection and energy-saving indicators of the declared products of raw materials, iron making, steel making, steel rolling and other processes, such as alloy saving amount, yield rate, clean energy use, fuel combustion efficiency, waste gas waste heat recovery, carbon emission, pollution emission, hazardous solid waste, steel slag, etc., and carried out initial factory inspection and product sampling testing for certified products. On-site review of the rationality of the production process, quality stability, test accuracy and system operation guarantee ability was carried out, and the review covered the production site involved in all the certification units of the product, and successfully passed the on-site audit.
"Green product certification" as the authoritative certification of domestic metallurgical products, the successful passing of this certification will lay the foundation for Xinda products to directly enter the national government procurement database and become the preferred product for government procurement; It marks that Xinda's products are higher than ordinary traditional production enterprises in terms of scientific and technological content, quality and management level, and it is easier to obtain the recognition of the industry and the whole society, and form differentiated bidding ability and brand premium force in the bidding, consolidating and expanding the quality reputation and market competitiveness of Xinda's brand; It also encourages enterprises to strengthen the quality management of green products, and plays a positive role in meeting the needs of customers for product quality and green manufacturing.
The company attaches great importance to energy saving and comprehensive utilization of resources, and generally adopts advanced environmental protection technology in the production process, forming the whole process of ultra-low emission reduction at the source, process control and end treatment. Has invested 1.11 billion yuan, the construction of a number of 100MW high temperature and high pressure and 50MW high temperature and high pressure gas generating units and steam waste heat generating units, 1×110MW ultra-high temperature sub-critical gas power generation projects; Built a sewage treatment plant, the first in local iron and steel enterprises to achieve full recycling of production and domestic sewage; The largest "transit rail" project in North China has been built, reaching the scale of the national second-class A marshalling station; Investment of nearly 300 million yuan to build industrial solid waste resource treatment plant, metallurgical slag waste into treasure, S95, S105 product powder is mainly used for downstream customers to produce high-grade building materials and decorative materials; The workshop is closed, soundproof equipment is built, and the noise meets the standard.
Iron and steel dust and non-ferrous metal smelting slag resource utilization technology, through the fire oxygen enriched combustion volatilization of raw materials and wet comprehensive recovery of valuable metals, solid waste zinc, indium, lead, cadmium, bismuth, tin, iron and other comprehensive recovery, and from the alkaline washing wastewater generated in the production process to recover iodine and sodium potassium industrial salt mix, industrial wastewater, after treatment, all back to production. Reduce new water consumption.
Sintering waste heat power generation technology in iron and steel industry, through the hierarchical use of sintering machine high temperature flue gas and ring cooler medium temperature flue gas, so that the waste heat boiler can maximize the use of 200 ~ 400℃ low temperature waste heat, steam in the evaporator of waste heat boiler and ring cooler medium temperature flue gas heat exchange. Then enter the superheater and sintering high-temperature flue gas for heat exchange into saturated steam to drive the turbine power generation, the technology does not produce additional waste gas, waste slag, dust and other harmful gases, reduce production costs, achieve energy saving and consumption reduction.
No by-pass non-pair reversing regenerative combustion energy saving technology, more than 3 regenerative burners are used as a group, each burner cycle to switch combustion or smoke discharge state, all high-temperature flue gas through the regenerator heat storage and then discharged, effectively improve the utilization rate of flue gas waste heat, while reducing the ignition and protection of cold air, reduce the cooling due to cold air blast, to achieve comprehensive energy saving.
The waste heat recovery technology of blast furnace slag water is used to cool a large number of high temperature slag produced after blast furnace smelting through the slag water, and a large number of slag water generated in the cooling process with a temperature of 70-80℃. The waste heat of low-grade blast furnace slag water is recovered through heat exchange technology and transported to the surrounding communities for heating.
The hot rolled ribbed steel bar for high quality reinforced concrete is our company's independent research and development of vanadium microalloying precipitation strengthening and production of high cleanliness seismic thread steel bar by ladle refining; The steel rolling adopts the international leading torsion-free and no-pass rolling equipment and technology, which makes the product have excellent environmental corrosion resistance, high strength yield ratio, high elongation seismic performance, long service life, high safety performance, and is an environmentally friendly green product.
Adhering to the development concept of "innovation, green, open and win-win", the company is the first iron and steel enterprise in Hebei Province to launch the carbon peak and carbon reduction action plan, won the title of "Hebei Green Factory", and became an A-level enterprise of environmental protection performance in the steel industry. And has won the national steel industry quality leading brand, national quality inspection stable qualified products, national quality inspection integrity enterprise, national quality integrity benchmarking enterprise, China excellent steel enterprise brand, Hebei excellent brand and other honorary titles.
Only by not forgetting the original intention, can we know the root and the root and firmly believe in it; Only by keeping the mission in mind can we know how to carry the burden and forge ahead. In the future, Hebei Xinda Group will give full play to the advantages of equipment, technology and talents, focus on the development direction of new steel products and new technologies with higher performance, lower cost, higher quality, better use, easier processing and more green, continue to increase scientific research investment, and develop high-quality low carbon steel iron materials with independent intellectual property rights. Build a high-quality steel manufacturing base integrating intelligent, efficient and green ecology, and help steel power and the smooth implementation of the two-carbon strategy!
