Abstract
The invention relates to a cooling element for cooling the fireproof lining of a metallurgical furnace. A cooling element is to be created, which prevents the cooling medium (water) from penetrating into the interior of the furnace, while providing continued good cooling action. This is achieved by a cooling plate facing the fireproof lining, a heat-conducting plate that is angled relative thereto, is firmly connected to the cooling plate and extends out of the furnace wall, wherein the cooling plate and the heat-conducting plate are made of solid material, and a cooling agent channel that is firmly connected to the heat-conducting plate, said channel being connected to a cooling agent inlet and a cooling agent outlet.
Description
Technical field
The present invention relates to the cooling element that a kind of refractory lining that is used for metallurgical furnace cools off.
Background technology
By EP 887 428 A1 and the known a kind of cooling element of DE 10 2,004 035 968 A1, it comprise make by copper or copper alloy, towards the plate of the refractory lining of metallurgical furnace (as shaft furnace), described plate is provided with the passage that is used for conduct coolant in inside.
The shortcoming of this cooling element is, towards the parts of stove inner room by cooling agent (being generally water) percolation and be interfered or during blow-by, water can arrive furnace interior.This is associated with very big danger.
Summary of the invention
The objective of the invention is to, a kind of cooling element is provided, it does not have this potential danger having under situation of better cooling effect.
This purpose is by realizing as lower member according to the present invention, that is: towards the coldplate of refractory lining; Setting, that be connected securely with coldplate with respect to this coldplate bending, by the extended heat-conducting plate in furnace wall, wherein, coldplate and heat-conducting plate are made by solid material; And the coolant channel that firmly is connected with heat-conducting plate, described cooling duct is connected with coolant outlet with coolant entrance.
Coldplate, heat-conducting plate and coolant channel are made by high conductivity material, are for example made by copper or copper alloy, and wherein, coolant channel advantageously extends along the narrow side of heat-conducting plate.
Because the high thermal conductivity of cooling element from the many like this heats of the region extraction between the steel plate of refractory lining and heat size device, makes that the cooling of heat size device no longer is essential (dry heat size device) from the outside, with spray water or passage cooling.Cooling element can by rolling/forge/copper coin of casting constitutes, described copper coin has the meticulous institutional framework that is used for good heat conductivity.According to suggestion of the present invention, two such solid material-copper coins can (but linking to each other in the mode of heat conduction) be welded into or bend to T shape profile (also can be L shaped profile) together.The end of the copper coin that is welded also with as the welding of the copper pipe of coolant channel.This copper pipe provides sufficient cooling with water quench and by the copper coin that connects to the furnace lining that is in the installation region of heat size device.
The size of each surface elemant and quantity, cooling circuit and derive according to essential heat from the distance between outstanding outwardly each heat-conducting plate of heat size device and to calculate and determine.For monitoring temperature/heat derived curve, cooling element is equipped with corresponding measuring instrument.
Cooling element can be installed in each position (top/sidewall/bottom, level with vertical) of heat size device between furnace lining and container steel wall/top/bottom.Preferably this cooler is arranged between the steel plate of refractory lining and heat size device at the lower area/zone line of container side wall (metal/slag Liquid region and support region (widerlagerbereich) or under direct current (DC) stove situation also in gas zones).In the support region of furnace lining, be provided with cooling element do not damage the heat size device at the set reinforcement in this position.Cooling element can be connected with the heat size device by bolt or analog.But between cooling element and furnace lining, press and fill out the contact material of heat conduction.
The copper pipe that welds by the outside applies cooling water to cooling element.Cooling element be arranged on the outside of heat size device through water-cooled part.Therefore under the situation that water is sewed, do not have water to enter into stove and be safe from harm the stove operation.A plurality of cooling element series connection connect into cooling circuit together.Yet single location is chosen such that promptly: continue to be cooled indirectly in the zone that is positioned at its next door when cooling circuit breaks down.Preferably cooling element should be connected to closed cooling circuit.
Yet if having cooling system semi-enclosed or that open when transforming, if the content of the quality of cooling water and suspended substance is within the tolerable limit (quality) of regulation, cooling element also can be connected in these cooling systems.
Can followingly summarize by the accessible advantage of cooling element according to the present invention:
Improve by the heat size device that reaches bone dry; With spraying-/the spray-type cooling heat with improvement of comparing derives.Also can in the zone that must keep, use the requirement of the static state of heat size device.With other systematic comparison, little opening that only need be in the heat size device, this stability and coupling to bottom container/upper container has active influence.The heat of exporting by cooling element is enough, so that prevent that not only related member is damaged but also the inboard of the process of facing cools down like this, makes by solidify, cooling or reactive little product composition autoprotection.
So, when realizing outside dry heat size device, particularly pollute when very serious and the corrosion of heat size device shell and because the obstruction of pump causes the cooling water interruption that stove is moved when problem is arranged when (sulphur/dust), produce further advantage in addition.Cooling element is not directly to contact and can make up with other copper cooling system no problemly with process or with product (slag/metal), and described copper cooling system is not in the static important zone of heat size device.This cooling element is particularly suitable for also being suitable in the protuberance of the bottom of rectangular vessel especially in the position that is difficult to access on the heat size device, and has to employ the spraying cooling of open type up to now in these places.Cooling element is spendable at AC/DC (AC/DC) the reduction furnace place with heat size device rectangle and circle.The latter is particularly advantageous, because it does not damage heat size device nature static/stability by kind, shape and installation site.
Description of drawings
Below explain the embodiment that is used for according to cooling element of the present invention with reference to the accompanying drawings.
Wherein:
