[0002] Coke oven, a furnace usually made of refractory bricks and refractory blocks, is used to oxidize coal to produce coke. It is a kiln that uses coal to make coke. It is the main thermal equipment for coking. The whole coke oven is built on a concrete foundation. In the process of building the coke oven, furnace columns are needed. The furnace columns distribute the protective pressure evenly and reasonably on the masonry, and at the same time ensure the sealing between the furnace head masonry, protective plate, furnace door frame and furnace door knife edge.

[0003] Existing coke oven columns are generally H-shaped steel. If the H-shaped steel is slightly bent, it will generally be straightened and repaired. In the prior art, straightening is generally performed by applying external force to the outside of the H-shaped steel in a cold state (normal temperature). Due to the particularity of the H-shaped steel, there are grooves on both sides thereof. If a bending depression occurs at the corresponding part of the groove, simply applying external force from the outside cannot effectively repair the corresponding part of the groove, and the repair effect is poor.

[0004] Therefore, it is necessary to propose a cold straightening and correction device for H-shaped steel used in coke oven columns to solve the above problems. Utility Model Content
