Torre circle supports the converter furnace, and pass the titled holding, and is the extremely important steelmaking mechanical components. Now all through the support of converter furnace, different specifications of circle parts of its use of furnace circle size is not the same as in, circle under different working conditions is very different from the constraint, and the load, analyzes the different condition strength meets its converter. Work process, by the heat load and circle of mechanical load and impact load the joint action, easy to produce the bad working conditions caused damage, crack based on finite element theory, using finite element software ANSYS in stress analysis of converter, the circle was studied under different condition stress distribution. The process of operation, body, except under circle of liquid steel and furnace accessories static load and transmit titled holding torque outside, still bear frequent rev, braking, and the dynamic load produced from furnace, steel slag pot, water, smoke hoods and spitting in content to wait of the radiation and heat conduction produces the heat load. Therefore, should have enough circle strength and rigidity.
