Definitions

  • This invention concerns an additional cooling system .with blown air for coils of hot-rolled metallic wire borne . .on a cooling roller conveyor and also concerns means able to .carry out said system.
  • this invention concerns an auxiliary. system to cool those pfirts of the metallic wire that lie near .the edges of the roller conveyor which obtains cooling with. .blown air and which is located downstream from the head for- .ming the coils, whereby said cooling is part of a known controlled process for cooling the wire as the latter leaves .the ho.t-rolling mill train.
  • the first stage is a strong water cooling process which takes place immediately after the last rolling stand, where- .as the second stage follows the format-ion of coils carried .out in the coiling means located downstream from said water cooling line.
  • the second coolinp stage is accomplished by blowing .cold air from beneath the powered cooling roller conveyor on which the coils of wire leaving the coiling device are .borne and partially superimposed on each other.
  • the cooling process is a thermal. .treatment which affects the micro-structure, and therefore . .the mechanical properties, of the wire, the formation of scale and also the uniformity and constancy of said properties. throughout the whole length of the coiled roire.
  • baffle plates have been provided to deflect the stream of cooling air and are located below the roller conveyor, their task being to spread the air in proportion to the thickening of the layers of coils lying above.
  • the purpose of this invention is to eliminate said problems.
  • a further purpose of this invention is to improve the second phase of the controlled cooling process.
  • Another purpose of the invention is to lessen the variations in mechanical properties along the wire.
  • One advantage of the invention is the elimination of further thermal treatments intended to improve the structure .and therefore the mechanical properties and to reduce there- .by the overall cost of the end product.
  • Another advantage lies in the fact that the system of . .this invention is applied to already existing roller convey- .ors.
  • the subject of this invention is embodied, therefore, .in an additional cooling system with blown air, whereby said system affects the zones of greater accumulation of material .near the edges of the roller conveyor by means of the pre- . .arrangement of means to blow cooling air along the edges of. .said roller conveyor, and whereby said blowing of air is co- .ordinated with the main blowing of cooling air from beneath the roller conveyor and can be regulated as regards its strength and orientation in the zones in question.
  • the device carrying out said additional cooling system comprises at least one tubular conduit means which feeds the cooling air and which is arranged lengthwise near the edges of said cooling roller conveyor and also comprises a plurality of means which blow: cooling air at an adjustable pressure and rate of flow and which are connected to said tubular conduit means, whereby. for the tubular conduit means some anchorage means are en-. visaged which permit adjustment of the direction of flow of the air towards the coils to be cooled in the aones of in-. terest.
  • Figs. I and 2 show together . the preferential embodiment 17 and the variant 117 of the system of the invention; however, it is to be understood . that according to the invention pairs of devices are fitted at the two edges of a roller conveyor and are constructed according to one or the other of the embodiments 17-117 which will be described separately hereinafter.
  • Fig.1 10 indicates the device forming the coils 11, .which are laid continuously on the movable roller conveyor 12 on which the second cooling phase is carried out.
  • the main cooling is obtained from beneath the roller conveyor 12 by means of a cooling system consisting of a plu- raltty of means delivering air, which here are blowers 13 fitted outside a box-like structure arranged below the rol- .ler donveyor 12.
  • Said structure has the shape of a channel with its base formed with adjustable baffle plate means 15, which regula-. .te the flow of air coming from the delivery means 13 into .the cooling channel 14, whereby the baffle plate means 15 .can be adjusted with an opener device 16.
  • the cooling system 17 is .shown on the righthand side of Fig.2 and on the lower side .of Fig.1 and comprises at least one air cooling conduit means 18 stretching along the roller conveyor 12 in correspondence .with each edge thereof and located at the side of said rol- .ler conveyor 12.
  • Said conduit means 18 comprises, in its side facing the .coils to be cooled, a plurality of blower means 19.
  • Said conduit means 18 are fed with cooling air by feed- .er means 20 connected to said conduit means 18, as shown in. Figs. I and 2.
  • Each of the blower means 19 consists, in this instance, .of a nozzle of a suitable type with an opening which diverges advantageously so as to create a substantially conical .air stream, but said blower means can be of another type or .shape and can include means to regulate the flow of their output of air.
  • some anchorage means 2I are comprised which can uphold the conduit means 18.
  • Said anchorage means 2I consist here of rings formed by two half-rings 22-122 which can be secured to each other, whereby one of said half-rings I22 is anchored in line with the structure of the roller conveyor 12 by means of the element 23.
  • the conduit means 18 are set on said stationary half-rings 122 and are clamped with the application of the other half-rings 22 by means of fixture means 24, which consist of threaded bolts passing through the half-rings 22 and screwed into the stationary half-rings 122.
  • said cooling air conduit .means 18, being connected to the means 20 feeding air is .equipped, on that side of itself facing the coils to be cooled, with a plurality of blower openings 25 from which comes. .the stream of cooling air, whereby said opening means 25 can .be provided helpfully, but not necessarily, with baffle means .26 located outside on the edges of said opening means 25 .with the task of forming an even flow of cooling air direct- .ed towards the band of coils requiring said flow for cooling purposes.
  • said plurality of length-. wise blower openings 25 is united, one with another, so as to form one single opening through which the stream of cooling air comes out along said lengthwise conduit means 18.
  • anchorage means 22 and fixture means 24 are envisaged which are substantially like those described earlier with regard to the preferential embodiment.
  • Said baffle plate means 26 can be regulated helpfully in relation to the conduit means 18 since said baffle plate means 18 can be hinged on the relative edges of the lengthwise opening means 25.
  • conduit means 18 or 117 located at the side of each edge, of the roller conveyor 12.
  • conduit means 18 10- cated in the middle of and above the roller conveyor I2 with a series of blower means 19 or opening means 25 directed towards the coils in the zones of the two edges of said roller conveyor 12.
  • blower nozzle means 19 can be swivelled in relation to the conduit means 18.
