The invention provides a method for designing a horizontal pull rod of a blast furnace hot blast surrounding pipe, comprising the following steps: Step 1, calculating the force generated by the wind pressure of the hot blast main pipe on the pull rod and calculating the force generated by the deformation of the hot blast surrounding pipe on the pull rod; step 2. Calculate the maximum acting force on a single tie rod according to the calculation result of step 1; step 3, determine the diameter of the tie rod according to the maximum acting force on a single tie rod. Through the design method of the horizontal tie rod of the blast furnace hot blast surrounding pipe of the present invention, general designers can quickly and accurately design the tie rod of the blast furnace hot blast surrounding pipe, and optimize the material and structural size of the horizontal tie rod under the premise of ensuring the safety factor and strength requirements Design to achieve the purpose of reducing costs.
Description
technical field [0001] The invention relates to the field of blast furnace design, in particular to a design method for a horizontal tie rod of a blast furnace hot blast surrounding pipe. Background technique [0002] For a long time, some structural parts of the blast furnace system have been designed with a sufficiently large size. The rigidity and strength of many structures far exceed the required safety factor, and their reliability is beyond doubt. However, ultra-high reliability However, the structural size of the material has great redundancy, resulting in a waste of material and an increase in cost. [0003] Some structural parts of the blast furnace system have not undergone reasonable design analysis, and are designed on the basis of original experience values. The engineering designers do not know which safety state the structure is in, and do not know how much redundancy exists in its structural dimensions and equipment capabilities. , so every time a new engin...
