Definitions
- the present invention relates to improvements made to the systems of radiant tubes used in particular in the furnaces for heating strips of metal products during parade.
- radiant tubes generally having a W configuration, also called a double pin, are generally used, these tubes ensuring the thermal transfer between the combustion gases emitted by a burner and the product to be heated, in particular a metal strip. continuously moving. The heat transfer takes place by radiation between the radiant tube system and the product to be heated and by convection / radiation inside the radiant tubes.
- the combustion gases at the outlet of the radiant tube system have a temperature of around 1000 ° C while the temperature of the radiant tubes is on average 950 ° C with a local maximum of the order of 1050 ° C.
- the present licensee has carried out an in-depth study of deformations by thermal expansion as well as the stress network associated with these expansions, these constraints. appearing during heating of the radiant tubes and during operation in stabilized mode or not.
- the aim of this study was to find the means making it possible to optimize the distribution of the stresses by taking into account the creep resistance of the materials which constitute the system of radiant tubes, this creep resistance varying strongly as a function of the temperature.
- the present invention therefore relates to a system of radiant tubes which has been improved by taking account of the results of said study.
- the simple support which supports the cold elbow is produced in the form of a console on which the cold elbow rests, before heating up the radiant tube, the cold elbow lifting up to leave this support as soon as heating.
- the cold elbow and the hot elbow are connected by means of brackets respectively from the foundry with its respective elbow, these brackets being connected together using a key or the like.
- the means ensuring the connection on the burner side between the intermediate elbow and the lower tube is produced using a leg from the foundry with this intermediate elbow on which is welded a stirrup-shaped part which can come '' press on the lower tube, an intermediate clearance being provided between the stirrup and the lower tube, the distribution of the stresses of the radiant tube being a function of the value of this intermediate clearance, and the resumption of the force generated by the intermediate elbow being provided by the lower tube in the part where it is the coldest.
- the heating furnace is used for the heat treatment of strips, in particular of metal strips 12, 12 ′ moving continuously in the furnace (process on parade).
- the heating is carried out using radiant tubes whose system has been designated as a whole by the reference 10, this system having as known a configuration in W or double pin.
- a burner 14 is provided outside the enclosure of the furnace and the combustion gases emitted by this burner pass through the system of radiant tubes 10 before escaping to the atmosphere.
- the radiant tubes therefore provide heat transfer between the combustion gases emitted by the burner 14 and the product 12, 12 ′ to be heated.
- the burner 14 is positioned on the lower branch of the system of radiant tubes, that is to say at the end of the lower tube 16 which constitutes the hot tube.
- the elbow 18 which extends the hot tube 16 constitutes the hot elbow of the system 10.
- the elbow 20 will be designated hereinafter intermediate elbow and the upper elbow 22 will be designated by cold elbow, this elbow opening onto the upper tube 24 which constitutes the tube cold radiant tube system 10.
- the cold elbow is provided with a support device the function of which boils down to a simple press.
- this simple support is produced in the form of a console 28 on which a support plate 26 can come to rest, made integral by any appropriate means with the cold elbow 22.
- the elbow associated with the support is the cold elbow 22 in which the most significant stresses are acceptable.
- FIG. 3 the variation in the temperature of the tube system 10 is shown as a function of its length, and the position of the respective elbows 18, 20, 22 is plotted on the abscissa.
- FIG. 4 the variation in the admissible creep stress as a function of the temperature of the tube system 10. This curve shows although the allowable stresses in the cold elbow region are much higher than those acceptable in the hot elbow. Such an arrangement is essential for the optimization of the constraint network.
- connection system between the hot elbow 18 and the cold elbow 22, this connection system being essentially characterized by the fact that it does not comprise any intermediate part (link).
- the elbow 18 is provided with a square 32 coming directly from the foundry with this hot elbow 18 and likewise the cold elbow 22 is provided with a similar square 30 also come directly from foundry with this cold elbow 22.
- the brackets 30 and 32 are obtained directly during the casting of the elbows of which they are respectively part. In no case should these brackets be added by welding to the elbows since such welds generate stress concentrations and risks of microcracking at locations where the stresses are maximum during operation.
- brackets 30 and 32 are connected by means of a connecting piece which can be produced in the form of a key such as 34, the design being such that the games allow relative movements of the hot 18 and cold 22 elbows when warming up, during operation of the oven in stabilized mode and during transients (power variation of the system of radiant tubes 10).
- the improved radiant tube system according to the present invention also comprises a connection between the intermediate elbow 20 and the hot lower tube 16, burner side 14.
- a connection between the intermediate elbow 20 and the hot lower tube 16, burner side 14. Such a system visible in FIG. 1 and shown in more detail in FIGS. 7 and 8 is essential for optimizing the distribution of system constraints 10.
- this connection system comprises a piece 36 in the shape of a tab, coming directly from the foundry with the intermediate bend 20 (any welding between the bend 20 and a connection piece such as 36 being prohibited for reasons indicated above with respect to the brackets 30 and 32) and a piece 38 in the shape of a stirrup which can be mounted on the lug 36 by welding since this lug does not support any constraint.
- connection by welding between the tab 36 and the part 38 in the shape of a stirrup is carried out after checking the intermediate clearance "j" between the stirrup 38 and the hot lower tube 16.
- the subsequent distribution of the components of the system of radiant tubes 10 depends on the value of this infill. In fact, when the oven is warming up, the intermediate bend 20 approaches the lower tube 16 up to the intermediate clearance "j" produced when cold and its movement is thus limited. This situation corresponds to a mapping of the distribution of the particular constraints for each infill set.
- connection of the lower 16 and upper 24 tubes with the sheet metal of the furnace can be carried out by any suitable means and in particular by any conventional technique. It will however be noted that the use of expansion bellows on one of the branches of the system of radiant tubes 10, as is provided in certain conventional embodiments, brings here more drawbacks than advantages and under these conditions the invention plans to carry out the connection between the lower and upper tubes and the sheet metal of the furnace without using expansion bellows.
