Abstract
The utility model discloses a copper cooling wall with a steel fiber liner. The heat carrying capacity of the copper cooling wall is high enough for resisting attack of strong heat flow. In past production practice, frequent shedding of slag crusts cannot be effectively avoided by inlaying silicon carbide bricks or filling unshaped castables into a copper cooling wall dovetail groove. Temperature fluctuation is caused by frequent shedding of the slag crusts, heat loss is increased, and normal operation of a furnace is affected. The heat face liner of the copper cooling wall is not easily sheared to shed, and the copper cooling wall is higher in affinity with liquid scrap iron in slag and capable of stably adhering the slag. The steel fiber liner filled in a heat face groove and a heat face is a layer of firm artificial scrap iron in slag. Owing to steel fibers, the liner with extremely high ductility is not easy to shed. In addition, the liner is excellent in affinity with the liquid scrap iron in slag, thereby being extremely easy to attach to the slag crusts during production.
Description
Technical field
The utility model relates to a kind of cooling device, relates in particular to a kind of copper cooling wall that is used on metallurgical furnace and the high temperature furnace.
Background technology
To use under the condition of soft water airtight circulating cooling system be overheated cooling device can not occur to copper cooling wall adopting, thereby 1993 are just applied in the world the high temperature furnace later on.A large amount of production practices prove that the work of copper cooling wall is very reliable.But it exists such problem: the purpose that the copper cooling wall dovetail groove is set is for dross, and shows that from the situation of reality the slag crust on the copper cooling wall hot side is unsettled.In operating process, frequent slag crust comes off and not only will cause interior heat flow rate per unit area of short time to strengthen suddenly, has increased thermal loss, and influence is operation normally.Analyze the reason that slag crust frequently comes off, mainly contain three aspects: the one, traditional refractory brick fragility of inlaying is big, and the toughness deficiency is very easily cut off in process of production and is come off; The 2nd, the affinity of traditional refractory brick and liquid slag iron is little, and slag crust is difficult to adhere to; The 3rd, copper wall hot side itself is also little with the adhesive force of slag crust.Therefore, need to improve copper cooling wall hot side structure, form and stablize dross.
The utility model content
The purpose of this utility model is to provide a kind of hot side liner to be difficult for being sheared to come off, and can stablize the copper cooling wall of dross more greatly with liquid slag iron affinity.
To achieve these goals, the utility model provides a kind of copper cooling wall with the steel fibre liner, comprise wall body, groove, described wall body is a hot side towards the one side at stove center, described groove is opened on the described hot side, it is characterized in that: also comprise the steel fibre liner, described steel fibre liner enriches in described groove and/or on the hot side.
Particularly, described steel fibre liner can adopt the material feeding cast of watering that contains steel fibre to form, and also can adopt the refractory brick that contains steel fibre to inlay formation, can also adopt the refractory matter ramming that contains steel fibre to form.
Preferably, described groove is for staggered anyhow.The steel fibre liner enriches the dynamics that combines that can increase with copper cooling wall body heat face in staggered anyhow groove.
Preferably, described groove is a dovetail groove.Oat tail groove structure can strengthen the fastening force of copper cooling wall body to the steel fibre liner.
Preferably, described wall body hot side upper limb or lower edge or on lower edge lateral projection simultaneously, filling of described steel fibre liner and lateral projection are contour.Can utilize the projection of wall body to protect the steel fibre liner, reduce shearing force this layer liner.
Preferably, described lateral projection≤100mm.
The utility model has the steel fibre liner owing to enriching in groove and/or on the hot side, compares the following advantage that mainly contains with existing copper cooling wall:
One, steel fibre liner itself is exactly good anti-material, can be used as artificial slag crust and is present in and has protected copper cooling wall on the hot side, avoids temperature fluctuation.
Two, because the existence of steel fibre is compared with traditional refractory material, and this layer steel fibre liner has very strong toughness, can under the effect of gravity, scouring force, not be sheared, so difficult drop-off.
Three, the steel fibre liner has higher thermal conductivity factor, and adding the steel fibre and the iron that wherein contain is element of the same race, and liquid towards slag iron has good affinity, and liquid slag iron is easily attached to top formation slag crust.
Because above-mentioned advantage, the copper cooling wall of band steel fibre liner can guarantee that slag crust securely attached on the copper cooling wall hot side, has reduced slag crust frequently coming off in operating process, thereby has reduced the fluctuation of the thermal loss and the thermal system of stove.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
