Tianjin Xingang Shipbuilding Heavy Industry Co., Ltd. started construction of the SCP integrated vehicle for the world's largest tamping coke oven. The SCP integrated vehicle is a mechanical device equipped by Xingang Shipbuilding Heavy Industry Co., Ltd. for the 4×46 hole 6.25 m four-coke oven of Tangshan Jiahua Coal Chemical Co., Ltd. Compared with the world's largest tamping coke oven, the tamping coke oven has the same length and height but increases the width by 20 mm. After the coke oven is completed, it will become the world's largest tamping coke oven.
The construction of the SCP integrated vehicle is provided by the Xingang Shipbuilding Heavy Industry General Contract, and the German KOCH company provides key design and technology. The new port shipbuilding industry is responsible for the technical transformation and manufacturing. The overall equipment of SCP integrated car will adopt the technology of automatic control, one-time alignment (alignment accuracy of ±5mm), automatic door memory and other world-class technologies. The entire coke oven project will be put into operation in October this year.
In recent years, with the increase of China's steel output, the increase of blast furnace volume and the shortage of high-quality coking coal, the tamping coke oven, which can significantly improve the quality of coke, has begun to be concerned by steel companies. Due to the low level of domestic tamping coal-loading machinery technology, there are problems such as high coal cake collapse rate, difficulty in continuous production of coke ovens, serious pollution of coal-filled flue gas, and difficulty in pushing coke. There is no large-scale iron and steel joint enterprise to build tamping coke ovens in China. Even with the use of tamping coke ovens, it has been eliminated in foreign countries for many years: all of them are fixed-station type tamping coal, coal-filled flue gas treatment using smoke-suppressing vehicles, and almost all manual manual operations. Since there is no spare equipment for the fixed-station tamping coke oven, the uninterrupted demand for blast furnace coke in the iron and steel complex cannot be satisfied, which is the most direct reason why large domestic steel conglomerates are reluctant to adopt large tamping coke ovens.
The tamping coke oven project built by Xingang Shipbuilding Heavy Industry Co., Ltd. adopts the world's most advanced SCP integrated car technology, that is, vehicle tamping, and at the same time complete tamping, coal loading and push-coke process, which can ensure the smooth operation of the energy of the entire steel enterprise. And one SCP one car can meet the production of two coke ovens. In addition, the coke oven will also adopt double U-tube smoke guiding technology, which will completely solve the environmental problems such as coal smog pollution in the past tamping coke oven; at the same time, rationally adjust the coal ratio to expand and shrink the coal. Adjustment within a certain range, put an end to the difficult to push the phenomenon.
After the completion of the project, China's tamping coke oven technology will reach the world's advanced level. Xingang Shipbuilding Heavy Industry has listed SCP integrated vehicle as the main product of the enterprise in the enterprise development plan. On the basis of contracting the SCP integrated vehicle contract amount of nearly 500 million yuan in 2007, it will cooperate fully with domestic and foreign steel joint enterprises in 2008. The industry is bigger and stronger.
