Abstract

The utility model discloses a lapped iron-notch combined brick, comprising at least two iron-notch bricks, wherein communicated molten iron outlets are formed in the iron-notch bricks; and lapping lugs for preventing blast-furnace gas from penetrating through and leaking are arranged at the brick joint ends (which are in contact) of the iron-notch bricks. According to the lapped iron-notch combined brick, the iron-notch bricks are combined together by in a lapped manner so that the blast-furnace gas is prevented from going up along the through brick joint; as a result, the operation safety is improved; and simultaneously, the iron-notch bricks can be prevented from being damaged untimely, and the service life of the iron notch and the service life of the blast furnace are prolonged.

Description

Lapping type iron mouth modular tile

Technical field

The utility model relates to iron-smelting blast furnace with iron mouth brick, is specifically related to a kind of modular tile that prevents iron mouth brickwork joint perforation leakage blast furnace gas.

Background technology

At present, the iron notch of blast furnace mainly adopts corundum and carbonaceous matrix material, is generally aluminium-carbon or carbon---silicon carbide material, and the iron notch brick body size of these blast furnaces is little, and an iron mouth generally has more than the hundreds of piece, and the iron mouth brickwork joint of building by laying bricks or stones is many.Some iron notchs are used bulk modular tile iron mouth instead, but because the straight shape brickwork joint of individual up/down perforation is arranged the iron mouth brick of outmost iron mouth brick and the inside, make the blast furnace gas of smelting generation first from the brickwork joint leakage of iron mouth brick, scurry out, and then corrode again the ferric oxide mouth, bring very large hidden danger for the flushing and casting workman of blast furnace, gas-fired and gas poisoning happen occasionally.And such iron mouth wastes time and energy when building by laying bricks or stones, the brickwork joint of building by laying bricks or stones is many, and the iron mouth bulk strength of building by laying bricks or stones is low.After blast furnace opening, operating duty along with high wind-warm syndrome and high smelting intensity, the brickwork joint that the blast furnace gas produced and alkali metal compound will cause the iron mouth region is loosening, and then generation string coal gas phenomenon causes that the blast furnace local temperature raises and causes iron mouth modular tile to damage too early, bury potential safety hazard for the production of blast furnace, cause blast furnace to repair or overhaul in advance.

The utility model content

The technical problems to be solved in the utility model is that blast furnace is too many because of the brickwork joint at iron mouth place, iron mouth brickwork joint up/down perforation easily reveals blast furnace gas, cause iron to make a slip of the tongue early damages, and provides a kind of and prevents that the straight shape brickwork joint of iron mouth from connecting and reveal blast furnace gas, extend the iron mouth lapping type iron mouth modular tile in work-ing life.

The technical solution of the utility model realizes in the following manner: a kind of lapping type iron mouth modular tile, comprise at least two iron mouth bricks, iron mouth brick is provided with the water hole of tapping a blast furnace be interconnected, and the brickwork joint termination of iron mouth brick contact is provided with anti-blast furnace gas and connects setting up the stage of leaking.

Described iron mouth modular tile comprises the first iron mouth brick and the second iron mouth brick, and the first iron mouth brick upper end is provided with boss, and the second iron mouth brick upper end is provided with and boss and the depressed part coordinated, and boss and depressed part form anti-blast furnace gas and connect setting up the stage of leaking.

Perhaps described iron mouth modular tile comprises the first iron mouth brick and the second iron mouth brick, the first iron mouth brick and the second iron mouth brick are provided with the water hole of tapping a blast furnace of connection, the upper and lower three-iron mouth brick that respectively is provided with of the first iron mouth brick and the second iron mouth brick, three-iron mouth brick form anti-blast furnace gas and connect setting up the stage of leaking.

The cross section of described three-iron mouth brick is wedge shape.

In the utility model, iron mouth brick adopts the overlap joint array configuration, makes blast furnace gas upwards not go here and there along connecting brickwork joint always, and then has improved operational security, can prevent that iron mouth brick from damaging too early, extended the work-ing life of iron mouth and blast furnace simultaneously.

Embodiment

Embodiment 1: as depicted in figs. 1 and 2, the present embodiment comprises the first iron mouth brick 1 and the second iron mouth brick 2, the first iron mouth brick 1 upper end is provided with boss 1-1, the second iron mouth brick 2 upper ends are provided with the depressed part 2-1 coordinated with boss 1-1, and boss 1-1 and depressed part 2-1 form anti-blast furnace gas and connect setting up the stage of leaking.The first iron mouth brick 1 and the second iron mouth brick 2 are provided with the mouth of a river 4 of tapping a blast furnace be interconnected.

The present embodiment is applicable to small blast furnace: after the first iron mouth brick 1 and the second iron mouth brick 2 combinations, boss 1-1 and depressed part 2-1 overlap, the brickwork joint contacted with the second iron mouth brick 2 along the first iron mouth brick 1 when coal gas is upwards when string, be subject to the obstruction of boss 1-1, prevent from revealing blast furnace gas, and molten iron flows out from molten iron mouth 4.

Embodiment 2: as shown in Figure 3 and Figure 4, the present embodiment comprises the first iron mouth brick 1 and the second iron mouth brick 2, the first iron mouth brick 1 and the second iron mouth brick 2 are provided with the water hole 4 of tapping a blast furnace of connection, upper and lower three-iron mouth brick 3, the three-iron mouth bricks and the first iron mouth brick 1 and the second iron mouth brick 2 overlap joints of respectively being provided with of the first iron mouth brick 1 and the second iron mouth brick 2 are combined to form setting up the stage of anti-blast furnace gas perforation leakage.

As shown in Figure 5, described three-iron mouth brick 3 is wedge brick, and the shape of three-iron mouth brick 3 makes the present embodiment be applicable to large-scale blast furnace: after several three-iron mouth brick 3 combinations, can coordinate and be combined into annular around the blast furnace inwall.In the present embodiment, the straight shape brickwork joint of the first iron mouth brick 1 and the second iron mouth brick 2 is all blocked by three-iron mouth brick 3 up and down, has prevented that the up/down perforation of coal gas from leaking.
