Description

Cooling agent panel and manufactured goods thereof flow

The present invention relates to a kind of panel that is applicable to such as mobile cooling agents such as air or water, and relate to the goods that this panel is housed such as electric arc furnaces or cooler bin etc.

This panel can be used for, for example form the stove inwall that resembles electric arc furnaces, can partly substitute more expensive refractory material, in addition, this panel can be used as, or component part, fire door or furnace roof, still, purposes concrete with it is irrelevant, the purpose of this furnace wall panel is to form a barrier layer in stove between hot-zone and the environment cold-zone, uses cooling agent to prolong the panel life-span.In addition, this panel also can be used for cooling such as liquid or gaseous mediums such as deep fat or hot-airs, for example, and can be by panel be immersed deep fat, or constitute method such as fuel tank by the several piece panel and reach.

In stove was used, known panel was if it is used to constitute a fire door or a furnace wall part, then generally to be rectangle; If it is used to constitute the part furnace roof of circular electric arc furnaces, then panel is fan-shaped.Yet irrelevant with overall panel shape, a panel that uses is configured at present, includes tortuous arrangement, circular cross-section, at the water pipeline of whole panel district extended configuration.Like this, this pipeline just comprises a plurality of parallel horizontal stretching pipeline sections, they are closely arranged mutually, between the bottom and top of panel, one root bead is (with regard to fire door or furnace wall portion) on another root, the length of horizontal tube part approximates the panel width, and, 180 ° return curved arranged in the horizontal tube end.Owing to have the pipe of necessary cross section and wall thickness, in less than 6 meters finite length, can obtain the producer, so next, such as to the tortuous pipeline of 40 meters of length overalls, for example 6 to 8 docking points (promptly using 6 meters long pipes) just must be arranged, docking point set is in by the center of panel in general, and, be the arcing furnace wall, these panels need to be curved cambered surface, but these contacts are oppressed in this bending unfriendly, usually make it to damage too early at these contact places or leak, an oral siphon need import cooling water into the arrival end of tortuous pipeline certainly, and an outlet pipe need spread out of water from lobster back way outlet end.Do the life-span except having disadvantageous casual labourer, the panel manufacturing processing of this furnace wall is expensive, this is owing to use the circular cross-section pipeline, must between adjacent horizontal pipeline section excircle, use the pipe joint (in-fill Pieces) of given configuration, simultaneously, different expansion and constriction coefficients usually causes bad welding between horizontal pipeline section and the pipe joint.And need between one section horizontal tube and contiguous horizontal tube, process 180 ° of return curved equipment.In addition, the application of circular cross-section pipeline, making has irregular surface in the stove, and thereby makes discontinuous chilled(cooling) water supply (CWS) is arranged in the stove.

Another kind of stove panel in the practice is so-called " box-shaped panel ", plate after its formation comprises one, the fin that forms coolant flow passages is welded to its medial surface, with a header board be soldered to, and the topped fin of living, finish the panel of band runner like this, yet this panel is owing to also need to be bent to the curvature of concrete stove for constituting the furnace wall, so also have only short working life, issue that living cooling agent is sewed and distortion etc. in operating temperature.

Another kind of panel structure is not from reality, but from GB 1,558,040 learn, it has narrated use square-section water-cooled box assembly, wherein each box assembly all has a water inlet connector that independently is positioned at an end, and the water out connector that is positioned at the other end.

Main purpose of the present invention provides a kind of panel construction, is applicable to cooling agent is flowed therein, existing relatively panel, and it is obviously simple, and makes that therefore processing is cheap, has the higher coefficient of overall heat transmission, and can increase the service life.

First aspect of the present invention is, a kind of panel is provided, be applicable to that cooling agent flows therein, include the ANALYSIS OF COOLANT FLOW pipeline, this pipeline has a coolant entrance at its arrival end, has a coolant outlet at its port of export, this ANALYSIS OF COOLANT FLOW pipeline comprises a plurality of lengthwise pipeline sections, and these pipeline sections constitute by having the hollow, rectangular section material, in parallel to each other configuration, or top that is stacked in another, or side by side, the top of adjacent contiguous pipeline section, the outer surface of diapire is adjacent, and the end of each pipeline section is closed, ANALYSIS OF COOLANT FLOW hole between the abutting end of contiguous pipeline section interconnects, in use, cooling agent flows at an end of each pipeline section, flows through along this pipeline section, flow out from its other end, constantly flow to and pass each pipeline section of panel afterwards.

Like this, according to the present invention, when it is compared with the tortuous pipeline panel of prior art, at first, can cancel pipe joint, like this, make it to simplify greatly, can weld more economically, and then, can eliminate along the butt joint at panel center, in addition, rectangular cross section pipeline section outer wall is smooth, this just may cause a plane, and it can think " heat " surface, is provided to for example stove or fuel tank internal, and therefore to cooling agent provide the contact hot-zone than large tracts of land, thereby strengthened hot transmission.Compare with the box-shaped panel of prior art, panel of the present invention used hollow, the rectangular cross section pipeline section, its benefit is that this pipeline section resists the inherent strength of deformation at work, and therefore, not only at work, and when it is shifted out stove so that when repairing or changing, can avoid causing that cooling agent sews, particularly when this cooling agent is water.When occurring panel in the handling and break, can save time and avoid damaging and do the relevant of panel under other panel situation and move.At last, with GB 1,558,040 compares, and panel of the present invention is provided with the ANALYSIS OF COOLANT FLOW mouth between adjacent tubular segments, so but the cooling agent Continuous Flow is crossed these pipeline sections, simplified whole panel construction greatly, therefore and reduced the expense of manufacturing, installation, displacement, and, reduced the possibility that cooling agent is sewed widely simultaneously also by a coolant entrance and an outlet bindiny mechanism only are provided.
