Hoa Phat has saved hundreds of billions VND thanks to innovation and technical innovation

With the characteristics of multidisciplinary and multi-field industrial production, in which iron and steel production activities use large amounts of electricity, water, coal, etc. Hoa Phat values the economical use of energy and natural resources and encourages the application of technical improvement initiatives implemented at the Group’s manufacturing plants.

In Hoa Phat, the Board of Directors always encourages and encourages the employees to promote their creativity. Therefore, every year, the innovation movement of member companies takes place very excitingly. Among them is Hoa Phat Hai Duong Steel, where there are several dozen initiatives, benefiting the company tens, hundreds of billions of dong each year.

Every year, the Company synthesizes initiatives in two stages and organizes reward and personal activities with the best initiatives. In 2019, Hoa Phat Hai Duong Steel Company has 55 innovation initiatives, with a profit of about VND 150 billion. These include the initiation of designing and installing the coal sorting system of Le Quang Vuong, Nguyen Van Duong – Steel Mill to select the right types of coal for production and removal of coal dust. The designed capacity of the system reaches 50-70 tons / hour, ensuring supply of coal for production, crushing and sorting of coal with specifications (particle size 8-10mm) to serve post-furnace alloying, type remove fine coal dust does not qualify. This initiative has saved the company VND 89 billion / year while ensuring the quality of coal supplied to the furnace, reducing the amount of dust generated when alloying after the furnace, reducing consumption and limiting emissions. generating coal dust when the alloy behind the furnace, take advantage of the fine coal dust provided for sintering.

And the initiative “Improving the quality of cast iron for casting machine system” by Mr. Ho Van Cuong, Director of Foundry PX, Steel Factory proposed registration to contribute to limiting the defects of casting crack, speeding up casting. Regarding technology, the initiative has completed the standard billet water cooling regime for each steel grade and each cast section cross section. For equipment, complete the process of calibration and installation of water plants, adjust R&M curved radius for casting machines. The collective spirit of this initiative not only helps to achieve the quality of cast iron but also benefits the company of more than VND 12.3 billion per year.

In order to find the optimal solution for the company in production activities, Mr. Dang Viet Thanh – Head of Technology proposed the initiative “Using blast furnace ore instead of sintered ore for silage production in the industrial sector blast furnace steel smelting ”is worth more than VND 11.35 billion / year. More importantly, the use of reversible ore completely replaced the sintered ore, meeting the requirements of blast furnace slag creation and furnace conditioning. Production and quality are satisfactory, since March 2019, there will be no shortage of sintered ores for 3 blast furnaces to use.

In addition, the Steel Plant also contributed two additional innovations: “Improving the cover of intermediate barrel” and “Fixing the surface of cast iron surface air” by Mr. Ho Van Cuong and Mr. Phung Nhat Quang – governing furnace management with an estimated benefit value of over VND 2.5 billion / year, etc.

Some initiatives are not high value, but have very important implications in production, contributing to the stable machinery operation, reducing raw material consumption costs, benefiting health, protecting the environment, ensure OSH for workers operating. There are important initiatives, creating new products for the company such as “Improving and perfecting the technological process of producing SWRY11 steel grade to replace 05Kπ as raw materials for welding rod steel production” of the Technology Department. Thanks to the application of this initiative, the Company has supplied nearly 5,500 tons of Ø 6 coils and nearly 200 tons of Ø 5.5 coils to welding rod manufacturers in the past year.

Hoa Phat Steel Pipe and many energy saving solutions reduce consumption of raw materials

With many innovations proposed, effectively applied in practice, steel pipe companies have benefited Hoa Phat with many billion dongs every year. More importantly, the movement has greatly spread to officials, engineers and workers in all factories and factories of Hoa Phat Steel Pipe nationwide.

At Hoa Phat Hung Yen Steel Pipe Factory, with 16 initiatives, in 2019, Hung Yen Steel Pipe has saved over 3.6 billion / year by improvement projects stemming from the actual work in production, bring high economic efficiency, help reduce raw material consumption, contribute to environmental protection.

Realizing that the power consumption at peak hours on production lines, especially the relatively high rolling line, accounts for 18-24% of the total electricity used, to save power for the factory, Mr. Tran Ngoc Duy – Technical Department, adjusted capacity, reduced rolling machine operating time during peak hours, increased productivity during off-peak hours. Thereby saving VND 1.36 billion / year in electricity costs for the plant when coming into operation.

The topic of reducing fan power by designing an inverter control circuit that can adjust the Cyclon fan speed from 0 to 100% of the rated speed of Mr. Hoang Van Vinh has reduced power consumption, benefiting the home machines of over 210 million dong / year.

In addition, the innovations of Hung Yen Steel Pipe also focus on topics of reducing raw material consumption and avoiding wasting materials such as the topic of making full use of straps at production stages of Mr. Truong Van Dinh Nguyen – Quality Control Department, during the production process, Mr. Nguyen saw BR32x0.9mm steel straps of material corrugated coils and plastic straps of galvanized corrugated iron coils, after being cut, all turned into scrap. propose to take advantage of these belts for the factory production stages. After applying this initiative, 50% of plastic belts have been reduced, completely reducing the amount of bits required for rolling, benefiting the factory VND 380 million / year.

A number of initiatives also contributed to improving the environment, limiting the risk of unsafe work while working as a project on reducing the acid vapor released through the breathing tube of HCL acid tanks at the plating factory of Mr. Nguyen Duc Co – Director of Hung Yen Steel Pipe Factory. Fabrication and erection of hoist beam for feeding Dainichi lathes and turning service, setting up CO2 welding of Mr. Dinh Van Chu, M&E Workshop reduces risks to people and reduces equipment failure.

At Hoa Phat Da Nang Steel Pipe Company, the initiative of production rationalization to save electricity for production was chaired by Mr. Huynh Thanh Thuan – Deputy Director of Da Nang Steel Pipe Factory, contributing to saving tens of millions of dong each. month. Particularly, the monthly saving station for galvanizing, bending, and pipe plating plants saves over 70 million dong, bringing remarkable efficiency. And the initiative of manufacturing semi-automatic sealing rigs by a group of mechanical technicians – Technical Department has reduced the labor force for workers, not overwork, ensuring safety for workers. The improvement of the blowing head inside the tube Φ 21mm, Φ 27mm also helps the plant reduce zinc consumption by over 20% compared to conventional blow molds.
