Vicasa made a great profit by improving its machinery

VICASA Steel Joint Stock Company – VNSTEEL is one of the typical four steel producers / traders of Vietnam Steel Corporation. Although known as the leading flag in the steel industry / V / but many of the equipment in the production line of VICASA are also outdated and outdated. Faced with this problem, the company is determined to make improvements to enhance its competitiveness in the market.

The company currently uses a 3-axis rolling mill with a frequency of 7 times to and fro back and forth in the steel rolling workshop. It is known that this rolling mill system has been investing a long time by the Company, so the technology is quite backward compared to modern steel rolling techniques. The rough rolling mill has many disadvantages that cannot be overcome through periodic repair and maintenance. Consumption of metal cutting continuous casting stage, cutting head during large rolling process, unstable production, low productivity. The largest capacity recorded at a rolling mill is only 140,000 – 150,000 tons / year, while the steel mill capacity reaches nearly 200,000 tons / year. This shows an imbalance between workshops in the production process, directly affecting the quality of output products.

In this regard, the Board of Directors and the specialized departments have agreed that it is necessary to improve the system of vertical rolling mills. With the goal of improving, upgrading and replacing the equipment of the existing cluster of rolling mills to a cluster of 6 vertical rolling mills; The company wishes to diversify its sources of embryos; at the same time reduce the cost of input materials, reduce economic and technical indicators; improve production capacity; Stabilizing product quality, increasing competitiveness in the market.

Investing in a vertical rolling mill to replace the existing one with a cost of VND 40 billion, increasing the capacity of the rolling mill line to 160,000 tons / year. At the same time, the Company has also invested in replacing a rough rolling cluster from a 3-axis-7-rolling-type rolling price to a 6-axis vertically-rolling type, 2-axis-6-rolling-rolling type and a post-cutting machine. Take advantage of auxiliary equipment such as hot induction induction furnaces, the ingot roller system simultaneously renovates and relocate the ancillary equipment in accordance with the new 6 vertical rolling mill unit. fitting. Officials and employees in the workshops closely coordinate so that the installation of new equipment and machinery goes into operation in sync with the current equipment, without affecting the stages in the production workshop.

Thanks to this vertical rolling system, VICASA has access to new technology, improve production skills. When the system of improved machinery and equipment went into operation, the Company helped reduce production costs and reduce metal consumption; increase capacity and product quality; stabilize production to increase product competitiveness in the market. Each year the company benefits up to 8 billion.
