Embodiment Construction
[0017] The present invention designs a lintel hanging form on the front wall of the smelting and holding furnace, such as figure 1 , figure 2 As shown, the hanging lintel girder includes upper channel steel 1, wide-flange H-shaped steel beam 2, vertical rib 3 and sealing plate 4, the upper channel steel 1 is No. 40b channel steel, and the wide-flange H-shaped steel beam 2 adopts the model It is H-shaped steel of 400×400×13×21. The upper channel steel 1 is arranged in parallel with the wide-flange H-shaped steel beam 2. The groove of the upper channel steel 1 is opposite to the H-shaped groove of the wide-flange H-shaped steel beam 2. There is a vertical bar 3 between the channel steel 1 and the wide-flange H-shaped steel beam 2. The vertical bar 3 adopts H-shaped steel with a model of 400×200×8×13. The vertical bar 3 connects the upper channel steel 1 and the wide-flange H-shaped steel The beam 2 is connected in one body; the upper surface of the upper channel steel 1 is pro...

The invention relates to a crossbeam of a hanging door lintel. Upper channel steel and a wide-flange H-shape steel beam are arranged in parallel; studs are arranged between the upper channel steel beam and the wide-flange H-shape steel beam; the upper surface of the upper channel steel is provided with a hole for connecting the upper channel steel with the bottom supporting angle iron of a heat screen; an H-shape steel web plate of the wide-flange H-shape steel beam is provided with a hole; the bottom surface of the wide-flange H-shape steel beam is provided with a seal plate; the seal plate is provided with a hole; the hole on the seal plate is concentric with the hole on the H-shape steel web plate of the wide-flange H-shape steel beam; the connecting bolt of a door lintel brick passes through the hole on the seal plate and the hole on the H-shape steel web plate of the wide-flange H-shape steel beam to fix the door lintel brick below the wide-flange H-shape steel beam; the front surface of the wide-flange H-shape steel beam is provided with a bolt hole for connecting the wide-flange H-shape steel beam with the heat-resisting casting of a furnace door frame; the back surface of the wide-flange H-shape steel beam is provided with a bolt hole for connecting the wide-flange H-shape steel beam with the door lintel brick; and the left ends and the right ends of the upper channel steel and the wide-flange H-shape steel beam are welded with the left upright and the right upright of a front wall. The structure has stronger practicality and is suitable for hanging the door lintel brick.
Description
technical field [0001] The invention relates to a girder structure for hanging lintel bricks. Background technique [0002] Heating and melting equipment is the dominant equipment in the metallurgical industry. Among the existing smelting and holding furnaces, the strength of the hanging girder is low, the high temperature resistance and oxidation resistance are poor, so the service life has always been low, and the actual service life is the shortest. Only three It will seriously affect the quality of smelting, holding furnace heating and melting, quenching and tempering treatment after metal smelting, and affect the maintenance cycle. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a structure for hanging beams with lintel bricks. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] Hanging lintel girders, including upper channel...
