Abstract

The utility model discloses a cast copper cooling wall without a buried pipe. The cast copper cooling wall is characterized by comprising a cooling wall body, wherein a boss is arranged on the cold surface of the cooling wall body, integrally connected cooling pipes are respectively arranged in the boss and the cooling wall body, a cooling channel arranged in the boss and the cooling wall body is molded in integral casting mode, and threads are processed on the boss so that the boss can be connected with other pipes. The cast copper cooling wall is not provided with a buried water pipe so that the problem of low heat transfer efficiency of the cooling wall caused by poor combination ratio of the buried water pipe and the wall body of the traditional cooling wall provided with the buried water pipe is solved. Simultaneously, the boss of the cooling wall extends out of a furnace casing and is connected with the outer pipes so that water cannot flow into a furnace even when the connection position of the boss and the outer pipes has water leakage, and production safety of the blast furnace is ensured.

Description

A kind of casting copper cooling wall without pipe laying
Technical field
The utility model relates to a kind of cooling stave.
Background technology
Copper cooling wall is widely used in the domestic and international blast furnace as a kind of efficient blast furnace cooling apparatus.The copper cooling wall of using at present is divided into two kinds: traditional pipe laying cast type copper cooling wall and rolling hole drilling type copper cooling wall, but these two kinds of copper cooling walls all have shortcoming.Wherein, tradition pipe laying cast type copper cooling wall is embedded with the metallic conduit of cast copper or other materials in wall body inside, because the restriction of casting technique causes usually can not merging fully between wall body and the pipeline, exist air gap, and air gap will have a strong impact on the heat-conducting effect of copper cooling wall, and then will cause cooling stave to burn out, leak.Rolling hole drilling type copper cooling wall then is that elder generation gets out the cooling duct in the rolled copper slab of monoblock, metallic conduit is welded on the hole-drilled cold rolling copper coin again.Although this manufacture need not be imbedded metal tube, avoided air gap problem between pipeline and the wall body, but the weld between metal tube and the copper coin is the weak link of this type cooling stave, in case weld seam goes wrong, in water coolant can bleed blast furnace from the commissure, consequence will be very serious.
The content of utility model
The purpose of this utility model is by a kind of casting copper cooling wall without pipe laying being provided, can realizing Wall of Blast Furnace is well cooled off, and can not stay again the hidden danger of leaking in the blast furnace.
For realizing above purpose, the technique means that the utility model adopts is: a kind of casting copper cooling wall without pipe laying, it is characterized in that: described copper cooling wall comprises the cooling stave body, be provided with boss on the huyashi-chuuka (cold chinese-style noodles) of cooling stave body, be provided with the cooling duct that links together in boss inside and the cooling stave body, wherein the cooling channel of boss and cooling stave inside is integral casting forming, is processed with screw thread on the boss in order to be connected with outside pipe arrangement, rear boss is installed is stretched out outside the furnace shell.
The hot side side of described cooling stave body is provided with inlays refractory brick or is coated with the unshape refractory layer.
Described boss place also is equipped with corrugated tube, the corrugated tube two ends respectively with furnace shell and cooling stave boss on steel ring weld mutually.
The cross section of described cooling channel is circular hole or flat hole, perhaps the attainable structure formation of other techniques.
The utility model has adopted the copper cooling wall of integral casting forming, can effectively take away the heat that transmits in the blast furnace by water coolant, and furnace wall and cooling stave itself are protected.Owing to not only do not have pipe laying but also do not have weld seam on the wall body, avoid occurring air gap on the one hand, thereby can give full play to the high thermal conductivity of copper, guarantee high cooling intensity and good cooling performance; Can not cause in stove, leaking because of weld cracking on the other hand yet.Furnace shell is outer to link to each other with outside pipe arrangement and the cooling stave boss stretches out, even damaged the leakage appears in the interface of boss and pipe arrangement, it is outer and can not leak in stove that water coolant also only can flow to blast furnace, thereby guarantee that cooling stave can long-term stable operation, is conducive to steady running and the longevity of blast furnace.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further:
As shown in Figure 1 to Figure 3, be cast with boss 2 on the huyashi-chuuka (cold chinese-style noodles) of cooling stave body 1, be provided with cooling channel 3 in body and the boss, be processed with screw thread 4 on the boss 2, integral casting forming is adopted in body, boss and cooling channel.Cooling stave hot side side can inlay refractory brick 5 or spraying unshape refractory layer is protected wall body.Cooling stave boss 2 places also are equipped with corrugated tube 7, the corrugated tube two ends respectively with furnace shell 6 and cooling stave boss on steel ring 8 weld mutually, be used for sealing and absorb cooling stave, furnace shell is subjected to thermogenetic nonaffine deformation after blow-on.After cooling stave installs, outside pipe arrangement 9 is connected to cooling channel 3 in the cooling stave by the screw thread 4 that processes on the boss, passes into water coolant again, cooling stave can be started working.
