Recently, the transformation project of mechanical vacuum pump of VD refining furnace of Jiangyin Xingcheng Special Steel Co., Ltd. (hereinafter referred to as Xingcheng Special Steel) contracted by Sino-heavymach successfully passed the final acceptance by the owner. The project started in November 2022, lasted six months, and succeeded in a one-time hot test in April 2023, and then quickly reached production and efficiency.
In order to achieve the goal of energy saving and efficiency increase and carbon reduction, Xingcheng Special Steel has changed the original imported steam vacuum pump system into a Mechanical Vacuum Pump System. The project adopts the unique three-stage mechanical vacuum pump solution and automatic control scheme of Sino-heavymach to fully meet the 24-hour continuous and compact steelmaking rhythm of Xingcheng Special Steel, fully applicable to the production needs of high-end steel such as tool steel, automotive steel and bearing steel. Compared with the imported steam vacuum pump system, the system does not need steam and turbid circulating water consumption, more low-carbon, energy saving and environmental protection.
Xingcheng Special Steel is a leading enterprise in China's special steel industry, and Sino-heavymach is a service enterprise for high-end metallurgical equipment in China. The strong combination of the two and the smooth and rapid production of the project fully prove the technical leadership and equipment stability of Sino-heavymach's Mechanical Vacuum Pump Systems.
Xingcheng Special Steel has an annual capacity of 6.9 million tons of special steel. The main products of Xingcheng Special Steel are high-grade bearing steel, gear steel, spring steel, free cutting non-tempered steel, mooring chain steel, continuous casting alloy round blank, curtain steel, extra thick steel plate, pipeline steel, wear-resistant steel, high-strength steel, pressure vessel steel, Marine and ocean steel, die steel, etc., which are widely used in transportation, petrochemical, machinery, offshore engineering, wind power, bridge and other industries. The market share of High-end bearing steel is the first in the country for 20 consecutive years, and the first in the world for 12 consecutive years.
