Description

Corrosion-resistant blast furnace iron runner

Technical Field

The utility model relates to an iron smelting field, in particular to a corrosion-resistant blast furnace tapping channel.

Background

The blast furnace tapping channel is a main blast furnace tapping channel, is an important facility in front of a blast furnace, has the function of realizing the separation of liquid slag and iron, and is divided into a forced cooling type and a heat insulation type according to different cooling modes in the typical main channel section in China; the difference between the two structures is that: the forced cooling type main iron runner adopts ventilation facilities to lead air to cool the steel runner shell through the cavities on the side wall and the bottom surface of the steel runner; from the perspective of heat transfer: the forced cooling type main channel design takes away heat in a forced cooling mode, so that the reasonable distribution of temperature is controlled; the heat insulation type main channel mainly controls heat conduction by means of thermal resistance of refractory materials between molten iron and a concrete structure, and reasonable distribution of control temperature is achieved.

The existing blast furnace tapping channel facilities in the current market have poor corrosion resistance, the cast surface structure is difficult to continue to be applied after being lost or damaged, the used stability is difficult to guarantee, the blast furnace tapping channel facilities are difficult to be put into use for a long time under the condition of lacking maintenance, and the blast furnace tapping channel facilities are not favorable for emergency production.

SUMMERY OF THE UTILITY MODEL

To the existing problem, the utility model provides a corrosion-resistant blast furnace tapping channel, which can effectively solve the problem provided in the background technology.

In order to solve the above problem, the utility model adopts the following technical scheme:

a corrosion-resistant blast furnace tapping channel comprises a brick lining body, wherein a prefabricated part mechanism is arranged at the top of the brick lining body, a slag layer body is arranged inside the prefabricated part mechanism, a ramming inner liner is arranged inside the slag layer body, a pouring layer is arranged inside the ramming inner liner, and corrosion-resistant pouring material working layers are arranged on the surfaces of the ramming inner liner and the pouring layer;

the prefabricated part mechanism is internally provided with a connecting hoop and a supporting rib shaft, and the supporting rib shaft is welded and installed on the surface of the connecting hoop.

As a further aspect of the present invention: the brick body of the brick lining body is of a brick body structure made of aluminum carbon materials.

As a further aspect of the present invention: the slag layer body, the ramming inner liner layer and the pouring layer are all made of aluminum carbon materials.

Compared with the prior art, the beneficial effects of the utility model are that: this corrosion-resistant blast furnace casting runner, through at the top layer, the corrosion resistant casting material working layer inside of the operation of directly accepting to pour sets up pouring layer and ramming the inner liner, it is more stable to make corrosion resistant casting material working layer itself set up the basis that combines, thereby be difficult to corrode, and lead to surface structure to run off or damaged back promptly suffering corruption or other destruction condition at corrosion resistant casting material working layer, can accept the operation of pouring of molten iron through pouring layer and ramming the inner liner, thereby realized greatly improving the effect of stability, be convenient for drop into for a long time under the condition of lacking the maintenance and use, and do benefit to emergent production.
