Abstract
The utility model pertains to the field of blast furnace cooling devices, in particular relating to a composite cooling wall for blast furnace cast steel. The utility model is formed by dopting cast steel as a cooling wall shell body, arranging a cooling water tube in the shell and using a quadric casting method. The composite cooling wall conquers the disadvantages of prior cast steel cooling walls of low stability of the cast steel cooling wall, low stretch rate and etc. and has the advantages of good heat stability, good intensity and tenacity in high temperatures, lengthened service life of the blast furnace and investment saving. The utility model provides an unearthly cooling wall for the broad enterprises using blast furnaces and is affirmatively to get a warm welcome of the consumers.
Description
The utility model belongs to blast furnace cooling apparatus field, relates to the compound cooling stave of a kind of blast furnace cast steel specifically.
Cooling stave is one of important cooling apparatus of blast furnace, at present, the domestic cooling stave that normally adopts traditional single cast iron quality, structurally adopt the cooling stave or the double-deck water cooling tube cooling stave of heavy wall of band boss form, there is structural stress in the former, the latter is that Inlet and outlet water tube head number is many, bring certain influence for the intensity and the stopping property of furnace shell, increased the workload of outside pipe arrangement simultaneously, common drawback is: the cast-iron cooling wall poor heat stability, hot strength is low, has a strong impact on blast furnace campaign, has influenced economic benefit of enterprises.
The purpose of this utility model is to adopt integrated poured cast steel shell, and the cooling stave of second pouring water-cooled tube structure in shell has solved the difficult problem of cast steel high temperature cast water-cooled tube fusing.Make cast steel replace cast iron to be applied on the blast furnace cooling stave.
The purpose of this utility model is realized by following technical scheme:
The compound cooling stave of a kind of blast furnace cast steel, adopt cast steel to do the cooling stave housing, place water-cooled tube in the shell, by adopting second pouring to form, be by the cast steel huyashi-chuuka (cold chinese-style noodles), the cast steel hot side, cast aluminium, water-cooled tube, tube stub, rising pipe, sleeve pipe is formed, its characteristics are: cast steel huyashi-chuuka (cold chinese-style noodles) and cast steel hot side are cast a monobloc container, dress water-cooled tube in the shell, water-cooled tube and cast steel huyashi-chuuka (cold chinese-style noodles), pour into a mould cast aluminium between the cast steel hot side, the equal holding pipe joint of the external part of water-cooled tube, the front end of tube stub takes on water pipe, the outer tubing of rising pipe, sleeve pipe is contained on the rising pipe, and the outer end is welded on the shell of cast steel huyashi-chuuka (cold chinese-style noodles) and with the contact position of cast steel huyashi-chuuka (cold chinese-style noodles) and surely closes mutually.
Adopt the compound cooling stave of the utility model blast furnace cast steel, can replace above-mentioned existing cooling wall structure, this compound cooling stave body has good thermostability and hot strength, toughness, prolonged blast furnace campaign, saved investment, overcome and now have shortcomings such as structural stress and working face inhomogeneous cooling be even with cooling stave, be the optional ideal cooling stave of vast use blast furnace enterprise, can be subjected to users surely and welcome.
Following structure accompanying drawing is further described the utility model:
Fig. 1 is the utility model one-piece construction synoptic diagram.
Embodiment:
As shown in Figure 1, the compound cooling stave of a kind of blast furnace cast steel of the utility model, be by cast steel huyashi-chuuka (cold chinese-style noodles) 1, cast steel hot side 2, cast aluminium 3, water-cooled tube 4, tube stub 5, rising pipe 6, sleeve pipe 7 is formed, its characteristics are: cast steel huyashi-chuuka (cold chinese-style noodles) 1 is cast a monobloc container with cast steel hot side 2, dress water-cooled tube 4 in the shell, water-cooled tube 4 and cast steel huyashi-chuuka (cold chinese-style noodles) 1, cast cast aluminium 3 between the cast steel hot side 2, the equal holding pipe joint 5 of the external part of water-cooled tube 4, the front end of tube stub 5 takes on water pipe 6, rising pipe 6 outer tubings 7, sleeve pipe 7 is contained on the rising pipe 6, and the outer end is welded on the shell of cast steel huyashi-chuuka (cold chinese-style noodles) 1 and with the contact position of cast steel huyashi-chuuka (cold chinese-style noodles) 1 and surely closes mutually.When the user uses by sleeve pipe 7, cooling stave directly is welded on the body of heater.
