Description
Technical Field
The utility model belongs to industry remains and reforms transform the field, concretely relates to upper portion is equipped with existing blast furnace body frame transformation structure that the intercolumnar supported.
Background
With the development of cities, the updating of cities represented by industrial legacy is rapidly advancing, wherein blast furnace retrofitting is one of the most common industrial legacy retrofitting. The modern blast furnace core usually adopts a form of a self-supporting furnace shell and a furnace body frame; wherein, the furnace shell is generally an annular shell made of thick steel plates, and the bearing capacity and the rigidity are higher; the furnace body frame is supported by the top of the furnace body frame, so that the upper part of the furnace body frame is often provided with inter-column supports, and the lower part of the furnace body frame cannot be provided with the inter-column supports due to the process requirements (the lower part of the blast furnace is provided with a hot blast surrounding pipe, an iron outlet, a slag hole and the like), so that the furnace body frame has the problems of lateral rigidity resistance and large and small upper and lower interlayer shear bearing capacity; in the past production, because the furnace shell bears the high temperature effect, the furnace shell generates great deformation in horizontal direction and vertical direction, so the furnace shell and the furnace body frame form a system and bear independently. When the blast furnace is shut down and is subjected to industrial legacy reconstruction, the situation that each layer of platform of the furnace body frame is reconstructed into a civil floor is met, although the high-temperature effect is avoided, in order to ensure a relatively complete process flow, a hot air surrounding pipe and the like still need to be reserved, at the moment, the lower part of the furnace body frame cannot be provided with an intercolumnar support, and therefore the furnace body frame still has the problems of side rigidity resistance and irregular upper and lower shearing bearing force among layers; how to keep a relatively complete process flow and solve the problem of the existing blast furnace body frame lateral rigidity and the irregularity of the upper and lower shearing bearing capacity between layers is one of the problems which need to be focused and solved when the blast furnace is transformed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a transformation scheme for solving the problem of irregular big-end-up under shear bearing capacity between existing blast furnace body frame lateral rigidity and layers under the premise of keeping relatively complete process flow.
A transformation structure of an existing blast furnace body frame with intercolumnar supports at the upper part comprises the existing furnace body frame, steel columns, steel supports, horizontal steel beams and horizontal support rods; the existing furnace body frame comprises existing furnace body frame columns, upper part inter-column supports and existing floor beams; the steel column top and the support bottom between the upper columns; the steel columns are positioned on two sides of the existing furnace body frame columns, and the steel columns and the existing furnace body frame columns form lattice columns through steel supports and horizontal steel beams between the existing furnace body frame columns; the horizontal stay bar is arranged between the steel column and each floor beam, and the lattice column and the floor beams are connected into a whole by the horizontal stay bar.
The steel column is arranged on the outer side of the existing furnace body frame column.
Furthermore, the newly added horizontal steel beams can be used as floor beams; an outer annular plate is arranged on the existing furnace body frame column and is connected with the newly added horizontal steel beam.
Optionally, when the existing furnace body frame column is a steel column or a steel pipe concrete column, the newly added support and horizontal steel beam are welded with the furnace body frame column by using a low-hydrogen basic welding rod.
The utility model provides an upper portion is equipped with existing blast furnace body frame transformation scheme that intercolumniation supported forms the lattice column through newly-increased component and former furnace body frame post, can remain relatively complete process flow and solve existing furnace body frame side direction rigidity and layer and receive the irregular problem of shear capacity big-end-up, and the construction is simple, has better market prospect.
