Hoa Phat Group applies a cyclic model in production

The circular economic model aims to effectively use natural resources throughout the value chain, from production to consumption and recovery, promoting the use of high-tech products and services, from It optimizes the use of resources, limits emissions to the environment and develops sustainably. Therefore, Hoa Phat Group has applied the closed-loop model in production right from the beginning of steel making.

Solution of closed circulation

The closed steel production process from iron ore to finished steel is a long cycle in which the output of one stage is the input of another. During the process, the recovery and reuse of waste gas, waste water, excess heat and even solid waste are treated in a circulation coin, without discharging into the environment, helping to save energy and protect environment, optimal production efficiency, product competitiveness.

This solution is applied to both Hoa Phat Iron and Steel Complex (KLH) in Hai Duong and Quang Ngai. The investment capital for environmental items of Hoa Phat steel accounts for about 20-30% of the total investment capital for the projects. The effectiveness of the application of closed circulation technology has been proved very specific in these KLH. With closed blast furnace technology, all waste, exhaust gas and wastewater are thoroughly treated, meeting the current standards in heavy industrial production, reusing circulation, and not discharging into the environment. The amount of iron-containing dust recovered during the process of iron and steel refining is also reused at the production stages, saving costs and improving the working environment.

Hoa Phat Steel selects the most advanced ultra-clean heat recovery coking coal technology in the world today, friendly to the environment. This is a technology to produce clean coke coal that recovers heat that meets environmental standards under the CDM clean development mechanism to reduce greenhouse gas emissions under the Kyoto Protocol. This technology eliminates all gases, fumes and toxic chemicals generated from the coking process, only recovers the heat energy to run the generator.

Thanks to this solution, Hoa Phat Hai Duong Steel Complex has a generating capacity of 64MW, contributing to proactively proactively 60% of the annual electricity demand. With the complex in Dung Quat and Quang Ngai, the autonomy power output is up to 70% thanks to 04 generating sets with a capacity of 240MW, bringing significant economic value, increasing competitiveness for Hoa Phat steel. Not stopping there, the Group’s member companies are continuing to research and improve technologies to increase generation capacity, reduce consumption of coal fuel and other materials to increase optimize the line device.

Turn blast furnace slag into building materials

Deep processing along the chain of steel products is a long-term strategic orientation of Hoa Phat Group. The collection and processing of blast furnace slag, a solid waste generated during iron smelting, has been in place since 2017, turning waste into a mineral additive for cement or used as input materials for enterprises producing concrete and cement.

Hoa Phat has optimized the technology of granulating slag with high pressure cold water and invested the slag crushing line in the Hai Duong and Dung Quat iron and steel production complex. This is a vertical crushing technology line, synchronized into the most modern type today. Hoa Phat’s S95 blast furnace slag products contribute to the thorough treatment of solid waste in Hoa Phat’s green steel production, turning solid waste generated in the process of pig iron smelting into building materials products, medium protecting the environment as well as creating a stable source of revenue for Hoa Phat Group, bringing significant added value to the steel production chain. 

With two irons and steel production complexes in Kinh Mon – Hai Duong and Dung Quat – Quang Ngai, Hoa Phat can supply to domestic and foreign markets 2.6 million tons of fine blast furnace slag granules per year, within In particular, Hai Phong KLH provides 750,000 tons/year and Dung Quat volume is 1.85 million tons/year.

S95 Hoa Phat fine grinding blast furnace slag has many outstanding advantages, applied as highly activated mineral additives for the production of cement, concrete, mortar or as a binder to reinforce weak ground. With S95, it is possible to produce mass concrete by reducing hydrothermal heat of concrete, producing heat resistant concrete due to increased thermal stability of concrete, durable concrete production in seawater, salt water environment and brackish water, due to the increased waterproofing of concrete, preventing the erosion of chlorine and sulfate, meeting the need to increase the life of works on the sea, on islands and coastal areas.

In particular, this product will help lower the cost of concrete by S95 Hoa Phat lower costs, while reducing clinker content in cement, thereby reducing CO2 emissions, contributing to environmental protection. According to the Circular No.10/2019 / TT-BXD of the Ministry of Construction, S95 blast furnace granular slag is used to replace up to 30% of PCB 40 cement in the material grading norm for all concrete mortars. This has opened an additional channel of consuming very large and convenient powdered blast furnace slag, which produces steel from iron ore such as Hoa Phat. From here, blast furnace slag particles of steel continue to contribute value to the community in an official and sustainable manner.

The product ecosystem of Hoa Phat complements each other effectively

Hoa Phat has 11 member companies providing a wide range of high quality products to the society with main products from construction steel, steel pipe, corrugated iron, pre-stressed steel, furniture, refrigeration, agriculture. In particular, the products of each sector group have close support.

High quality rolled steel is the raw material for production of wire drawn steel, pre-stressed steel, welding rod core, etc. Hot rolled steel coil (HRC) is the input material for the production of steel pipes, galvanized steel, shaped steel, industrial steel, other mechanical. The Group’s steel products are also supplied to apartment projects, industrial park infrastructure and in construction of farms in the agricultural sector.

Some steel and corrugated iron products are used in the manufacture of interior and refrigeration products. Plastic factory of refrigeration can produce product details not only of refrigeration, but also of Furniture. In addition to the market, the domestic animal feed also provides the internal livestock farm system across the country with a fairly large output.

In particular, the implementation of Hoa Phat Dung Quat Iron and Steel Production Complex project uses thousands of tons of steel pipes and high-quality color-coated corrugated iron of the Group, helping to ensure the progress and quality of the project. with the most reasonable cost. Mutual complementarity between operational areas contributes to cost optimization, reducing initial investment for the Group’s projects and production activities.
