ABSTRACT:This design required annual for 1.5 million tons of production building blast furnace ironmaking workshop. Bf: namely, that the seven system workshop of blast furnace body system, feeding system and slag iron processing systems, injection system, air distribution system, dusting system and cooling systems are made relevant narrative. And the site selection and workshop layout also should make overall design. The design of the main contents include equipment type, size calculation, process calculation (including ingredients calculation, material balance and thermal equilibrium calculation) and production capacity calculation.

Blast furnace ironmaking is the main means to obtain pig iron and steel metallurgical process, is one of the most important link in national economic construction and plays an important role. The main equipment of blast furnace ironmaking is, in line with high quality, high output, low cost and environmental pollution, the policy design and build small with an annual output of 1.5 million tons of blast furnace ironmaking workshop. Design of blast furnace seat number is 2 selected per seat, the volume of 1029.2 sockets for blast furnace. Blast furnace adopts the whole cooling stave, one ZhuanBi thin-walled lining, copper cooling stave, total water softener closed loop cooling system, pwi string of tank top, no bells internal-combustion type hot air stove, all dry type bag dust removal and so on a series of advanced practical technology. Meanwhile, the design with some of the domestic and international similar blast furnace advanced production experience and related data, and strive to make the design of blast furnace is accomplished reasonable, longevity, practical, in order to achieve the optimal production efficiency.
