Embodiment Construction
[0031] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] Such as figure 1 A replaceable blast furnace tapping trough shown has the same basic structure as the traditional tapping trough, and the matrix is also composed of an inner mold (hook lining), an outer mold (steel structure shell 3) and a masonry base for restraint. The refractory material 2 between the two (can be castable, ramming material and other reasonable refractory materials for iron trough), and the difference is that this movable and quick replacement iron trough is as follows Improvements in:
[0033] First of all, the tap trough is no longer fixed on the casting yard, and the yellow sand and refractory bricks on both sides of the fixed tapping trough have been cancelled, and the surrounding area of the iron trough has been emptied, showing that the tapping trough can be located on the casting...

The invention provides a replaceable blast furnace iron runner. The replaceable blast furnace iron runner comprises a substrate, a reinforcement unit and a replacement unit. The substrate comprises an outer die, an inner die and a fireproof material arranged between the outer die and the inner die. The reinforcement unit comprises a first reinforcement structure and a second reinforcement structure, wherein the first reinforcement structure is used for guaranteeing that the iron runner can bear related stress but not deform in the replacement operation, and the second reinforcement structure is used for guaranteeing that the iron runner can bear the weight of a work layer of the iron runner in the replacement operation. The replacement unit is arranged on the outer die and used for achieving transferring-out or receiving of the iron runner relative to an iron-smelting blast furnace. By means of the replaceable blast furnace iron runner, the maintenance environment of the iron runner is greatly improved on the one hand, and on the other hand, as the maintenance of the iron runner does not occupy normal operation of the iron-smelting blast furnace, the work efficiency is improved.
Description
technical field [0001] The invention relates to the design field of a blast furnace casthouse, in particular to a replaceable blast furnace tap trough. Background technique [0002] Blast furnace iron trough is an essential infrastructure in the blast furnace ironmaking process engineering. Its main function is to buffer the slag and iron ejected from the taphole, realize the separation of slag and iron, and further transport the slag and iron to the ladle and slag pellets respectively. chemical facilities. [0003] At present, in blast furnace ironworks facilities, regardless of the size of the blast furnace or the type of molten iron it smelts, the position of the blast furnace iron trough is generally relatively fixed, and this setting method has the following disadvantages: [0004] Corresponding to the normal operation, the relatively fixed position leads to the maintenance of the tapping channel must be carried out in front of the furnace, and the environment in front...
