Provide you with 6 patented practical technologies

TCS acid oxidation pellet roasting shaft furnace and its high-quality shaft furnace pellets solve the problem of fine materials and blast furnace ironmaking plants with the lowest investment The problem of optimal and reasonable charge structure. It is a low-investment and high-profit project for the technical transformation of the earth-fired pellet plant and the deep processing of iron concentrate in the iron ore dressing plant.

The large-scale modern TCS annular shaft furnace can greatly improve the grade and concentrate level of the iron-making blast furnace. It lays a good foundation for increasing the furnace top pressure and oxygen-rich large-scale coal injection, reducing the cost of pig iron and improving The output and pig iron quality of iron-making blast furnaces can be greatly improved, thereby greatly improving the efficiency of steel-making and continuous casting machines, reducing the consumption and cost of steel-making steel materials, and extending the life of blast furnaces and converters.

It has the characteristics of large scale, high quality, low cost, land occupation, low investment, low power consumption, high efficiency, short construction period, quick results, etc. It can completely eliminate the environmental pollution problem of soil burning. Using high-quality shaft furnace pellets to replace earth-fired pellets and raw ore, and using them in conjunction with high-alkalinity sinter is the basis for fine materials. Since the grade of TCS shaft furnace pellets is as high as 63% to 65%, and FeO is less than 2%, especially It is the high-temperature metallurgical properties such as reduction and powdering rate that are much better than imported rich ore blocks and earth-fired pellets, which will make a big leap in the economic benefits of the entire steel enterprise. All steel companies with good economic benefits are made by taking the path of concentrate. The production and operation situation of enterprises has fundamentally improved.

TCS acidic oxidation pellet roasting shaft furnace (Patent No.: ZL 00 2 60319.5) After several years of industrial production practice, the technology has become increasingly perfect, the advantages have become more prominent, and the production technical indicators have reached the domestic advanced level. In 2004 In June 2004, the Hebei Provincial Department of Science and Technology passed the appraisal of scientific and technological achievements (Jike Jianzi [2004] No. 613), and it was deemed that the patented technology has "high scientific and technological content, reliable technology, advanced and reasonable, and is worthy of application and promotion in the same industry"; TCS acidic oxidation pellet roasting shaft furnace has "high utilization coefficient, can be designed on a large scale, has high oxidation pellet quality, has the characteristics of low one-time investment, low operating cost, and long furnace life"; it is "the ideal choice for small and medium-sized steel enterprises" The transition of large and medium-sized steel enterprises to more ideal furnace charge production facilities will bring higher economic benefits to the enterprises." He also pointed out that "the successful development of the circular shaft furnace represents the development direction of the new generation of oxidation pellet production facilities. , has practical significance for promotion at home and abroad"; "This achievement can promote the large-scale development of shaft furnaces, has good promotion prospects, and the technical level has reached the domestic advanced level."

TCS’s patented acid oxidation pellet roasting shaft furnace technology breaks through the international problem of large-scale shaft furnaces and successfully uses its own waste heat to preheat the combustion air temperature to above 280°C. It has achieved actual production results of saving investment, saving land space, low energy consumption, low cost and high quality. It is a "short, flat and fast" technical transformation project for the production of iron-making blast furnace concentrates.

TGS type energy-saving and environmentally friendly activated lime kiln. Energy-saving and environmentally friendly active lime kiln is a technology with low investment, low cost, quick results, mature and reliable, and meets environmental protection requirements. It has strong market competitiveness and broad market prospects.

TGS type energy-saving and environmentally friendly activated white ash kiln, patent number (ZL 2003 2 0112063.3), can provide high-quality activated white ash (activity ≥ 300ml) for steelmaking production. At present, three furnace types, TGS150, TGS200, and TGS300, have been designed and developed; three TGS150 lime kilns of Shanxi Wenshui Haiwei Iron and Steel Co., Ltd. have been completed and put into operation; three TGS150 lime kilns of Hebei Wenfeng Iron and Steel Co., Ltd. have been built and are scheduled to be completed in June 2006. It will be put into operation in March; in the second phase, three more TGS200 lime kilns are expected to be built;

A high-efficiency dust collector with desulfurization function.

By applying this technology to the multi-chamber composite blast furnace tuyere (or baffled tuyere set), the ironmaking plant can increase the life of the tuyere by more than 2.73-3 times without investing in water supply equipment, and greatly reduce the cost of the tuyere. Damage to the tuyere may cause adverse effects such as production shutdown on the ironmaking blast furnace.

Tangshan Iron and Steel Plant and Chengde Iron and Steel Cement Plant, which were the first to apply it, have achieved an annual increase in output value of 3.621 million yuan and an annual increase in profits and taxes of 1.268 million yuan. At present, it has been promoted to dozens of domestic manufacturers. This product won the gold medal and quality award at the 1993 Hebei Youth Science and Technology Expo.
