Abstract
The utility model discloses a water tank for the furnace mouth of a steel converter, characterized in that a body 1 cast of alloy steel is provided with a cavity 2 with a trapezoid cross-section, an inlet tube 3 and an outlet tube 4. The two tubes are separated and communicated with circulating water. The utility model cast in form has easy fabrication, large circulating water flow and good cooling effect. Due to the adoption of the alloy steel, deslagging can be done with a hand hook, thus the mean service life is enhanced by forty times.
Description
The utility model belongs to metallurgical steelmaking technical field, and specifically, it relates to a kind of essemer converter fire door water tank, especially adopts the stainless heat-resistant alloy steel monoblock casting to become the converter mouth water tank of large section cavity type.
The fire door water tank is removable relatively independent parts in converter integral body, so that change.Known essemer converter fire door water tank is the moulding of general carbon steel welded steel plate.Built-in cavity recirculated water cooling.This fire door water tank is shorter work-ing life, and average is 250 heats.And fire door water tank manufacturing processed difficulty is big, and intensity and resistance to elevated temperatures are poor.Particularly easy dry slag must remove the gred with the oxyacetylene metal-cutting method.Fire door water tank rapid wear in convertor steelmaking process needs often to change.Except that the consumption of water tank own is big, also seriously influence the rate of coming out of the stove, even caused shutdown maintenance, cause bigger financial loss.Domestic once the appearance casts with graphitic pig iron, built-in snakelike conduit formula converter mouth water tank.This technology can solve the difficulty of manufacturing processed and the weakness of intensity difference more effectively, but the snake pipe circulating water flow is little, and cooling performance is poor, still can not be high temperature resistant, and burst easily, work-ing life is generally between 300～800 heats.
The purpose of this utility model provides a kind of large section cavity type fire door water tank that adopts the stainless heat-resistant alloy steel monoblock casting to become.It can increase the service life effectively, improves the cooling performance of water tank, and has not dry slag, is difficult for bursting and characteristics such as high temperature resistant.
The purpose of this utility model is achieved in that with stainless heat-resistant alloy steel and is cast as the converter saliva case with large section ladder cavity, annotates recirculated water in the cavity and plays cooling effect.
The utility model is owing to adopt the stainless heat-resistant alloy steel casting, and its material capability and melting straight carbon steel difference are big.Be difficult for dry slag.The dry slag phenomenon occurs and can remove the gred with pew, and intensity and all raisings greatly of high thermal resistance.In addition because the increase of internal recycle water chamber cross section.Make special ring discharge increase good cooling results.Can reach 10000 heats mean life.Thereby reduced production cost.Improved plant efficiency.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Below in conjunction with accompanying drawing the utility model is further described.
The utility model comprises a stainless heat-resistant alloy steel converter mouth tank body 1, casts out a trapezoid cross section cavity 2 in the body, cuts off with muscle between water inlet pipe 3 and the rising pipe 4.
Recirculated water enters ladder cavity 2 by water inlet pipe 3, is discharged by rising pipe 4, and circulation is fully cooled off fire door.
Claims (2)
1, a kind of converter mouth water tank comprises body 1, water inlet pipe 3 and outlet pipe 4, it is characterized in that being provided with ladder cavity 2 in the inside of body 1.
2, converter mouth water tank according to claim 1 is characterized in that body 1 adopts the stainless heat-resistant alloy steel casting.
