Abstract
The utility model discloses a kind of ironmaking stove, comprise: stove sheet metal shell, reasonable Arrangement be welded in the good refractory metal of heat conductivility inside stove sheet metal shell or nonmetallic heat conduction tack claw, and ramming the amorphous refractory material be consolidated on this tack claw.Stove housing adopts the sheet metal that mechanical strength is large; Because heat conduction tack claw adds heat conductivility and the heat impact strength of amorphous refractory lining, thus the water-cooled protective effect of stove liner is strengthened.Further, also easily form stable dross layer on the surface of liner, thus make the liner of stove obtain more effectively protecting.The most important thing is due to the heat conduction tack claw of the present utility model material not affecting molten steel quality, even if therefore in the use latter stage of ironmaking stove, also can normally use.
Description
Technical field
The utility model relates to metallic iron or ferroalloy field of metallurgy, especially relates to flash ironmaking stove.
Background technology
The in-furnace temperature such as blast furnace and flash iron-smelting furnace can up to 1550 DEG C, and the solution usually adopted at present is in refractory brick marshalling, inlay expensive copper water cooling wall or copper water jacket.Although fine copper heat conductivility is good, fusing point only 1083 DEG C, if it is careless slightly therefore to supply water, water-cooled protection element melts rapidly, and this is the major reason that various ironmaking stove copper water-cooling wall or Copper Water Jacket leakage accident happen occasionally.Copper water cooling element can peel off because of high temperature corrosion inevitably in running on the other hand, causes the hot metal composition of output defective because of cupric time serious.Seek that cost is low, security of operation, easily construction and the ironmaking stove liner repaired and be the common requirement of steel industry.
Utility model content
Given this, the utility model provides a kind of ironmaking stove.
Ironmaking stove has blast furnace and various non-blast furnace ironmaking stove.Described ironmaking stove comprises: stove sheet metal shell, reasonable Arrangement be welded in the good refractory metal of heat conductivility inside stove sheet metal shell or nonmetallic heat conduction tack claw, and ramming the amorphous refractory material member be consolidated on this tack claw.Meanwhile, one circle spray pipe and corresponding raggle are at least set in stove hull outside.Stove housing adopts the metallic plate that mechanical strength is large; Spray pipe and corresponding raggle are fixed on the outside of described stove housing, and spray pipe to the direct continual even water spray in top of stove hull outside, and forms uniform moisture film in stove hull outside face, and is finally discharged by raggle; Because heat conduction tack claw adds heat conductivility and the heat impact strength of amorphous refractory lining, thus the water-cooled protective effect of stove liner is strengthened.Further, also easily form stable dross layer on the surface of liner, thus make the liner of stove obtain more effectively protecting.The most important thing is because heat conduction tack claw of the present utility model belongs to the material not affecting molten steel quality, even if therefore in the use latter stage of ironmaking stove, also can normally use.
In the technique scheme of this ironmaking with stove, can avoid adopting expensive high refractory brick and fine copper water-cooling wall or water jacket, thus significantly reduce the cost of ironmaking stove.Further, the ironmaking stove that the utility model provides is without copper liner and construction method, and construction is simple, and easy spray repair is repaired, simultaneously low to water quality requirement, and safety.
