Definitions

  • This invention concerns an ingot mould with a tubular . crystallizer.
  • the invention concerns an ingot mould for continuous casting provided inside with a tubular crystallizer of a modest thickness, whereby an interspace within which a cooling liquid circulates is envisaged outside the tubular crystallizer.
  • Known ingot moulds consist generally of one single tubular body having a great thickness for withstanding and dispersing considerable amounts of heat, whereby said tubular body. acts as a crystallizer and is made of a special and very ex-. pensive copper alloy able to withstand high temperatures and. to disperse the heat quickly, in the meanwhile undergoing li-. mited wear and facilitating good performance of the crystallization process and withdrawal of the ingot.
  • Said known ingot moulds are cooled on their outside and, when the inner walls of the crystallizer become worn and de-. teriorate, steps are taken to replace the whole ingot mould..
  • ingot moulds consist of one single very thick tubular body made of an expensive material, the necessary .replacements of the ingot mould represent a great burden for .the user.
  • the purpose of this invention is to embody an ingot mould wherein only the inner part with a modest thickness is. made of a valuable material, and wherein an interspace between .the inner part acting as a crystallizer and the remaining part of the ingot mould is comprised together with suitable ducts; .in said interspace a cooling liquid runs and is able to en- . .sure dispersion of heat and the efficient working of the crys- .tallizer and to improve the conditions for cooling the crys-. .tallizer, above all in the portion nearest to the feed of the .crystallizer itself.
  • the ingot mould of the invention provides the advantage of improving the cooling of the crystallizer, above all in the end part and end surface near to the feed of liquid metal.
  • the ingot mould of the invention also entails the advantage of minimising the employment of valuable material and is .of a more economical overall construction.
  • Yet another advantage of the ingot mould of the invent- .ion is that it permits an easier and quicker regulation of the cooling intensity by varying the flow and/or characteristics. .of the cooling liquid.
  • the invention is therefore embodied in an ingot mould .with a tubular crystallizer for continuous horizontal casting, said ingot mould being characterized by including in coordinate cooperation: .
  • the ingot mould of the invention com- .prises a replaceable tubular crystallizer having a modest .thickness and made of valuable material, whereby said crystal- .lizer is located in the inner part of the ingot mould and is. .equipped at its end facing the feed of metal with a flange which is suitable for improving the connection to the feed . .channel envisaged upstream from the ingot mould and for im- . .proving the conditions for cooling the end of the crystalli-.
  • the ingot mould also comprises a tu 7 bular cooling sleeve made of ordinary steel or cast iron, . whereby said sleeve is located in the outer part of the ingot mould, is provided on its inside with a tubular jacket having an inner diameter greater than the outer diameter of the crystallizer tube, is able to form, together with the outer sur-.
  • an interspace for the circulation of the cooling liquid is also equipped with two annular chambers made between said jacket and the tubular cooling sleeve; one of said annular chambers is envisaged as being in the end of the ingot mould facing the direction of withdrawal of the ingot and communicates radially with the interspace formed by the jacket of the tubular cooling sleeve and by the crystallizer tube and is provided with at least one inlet for cooling liquid, whereas the other annular chamber envisaged . at the end of the ingot mould facing the feed is provided with at least one outlet for cooling fluid and communicates with .
  • 10 is the ingot mould according to the invention
  • 20 is the replaceable tubular crystallizer, which has a modest thickness and is made of a valuable material and located in the inner part. of the ingot mould 10
  • said crystallizer 20 is equipped on its outside, at its end 120 facing the feed of liquid metal,. with a flange 24 able to improve the conditions for cooling .
  • said end 120 and to improve the connection of the ingot mould 10 to a feeding device envisaged as being upstream from said. ingot mould
  • said crystallizer 20 is equipped on its inside . with an initial portion 21 having a smaller diameter than that of the remainder 22 of the inner conduit of the crystallizer.
  • 30 is a tubular.
  • cooling sleeve made of ordinary steel or cast iron and is located in the outer part of the ingot mould 10 and is equipped on its inside with a tubular jacket 32 secured to said tubu-. lar cooling sleeve 30 by means of anchorage rings 34,whereby.
  • said tubular jacket 32 has an inner diameter greater than the outer diameter of the crystallizer 20 and, together with the. outer surface of said crystallizer 20, is able to form an interpsace 33 for the circulation of cooling liquid on the outside of the crystallizer 20.
  • the tubular sleeve 30 is provided at its ends with two. annular chambers 36 made between the tubular jacket 32 and . the outer body of the tubular sleeve 30.
  • the annular chamber 36 made in the end of the ingot mould 10 facing in the direction of withdrawal of the ingot . communicates radially with the interspace 33 formed by said . jacket 32 and by the crystallizer 20 through holes 136 provided in the jacket 32 so as to correspond with the end 233 of. the interspace 33 and comprises at least one inlet (not shown .in the figures) for the cooling liquid.
  • Said annular chamber 36 and the interspace duct 33 are. delimited, on their side facing in the direction of withdraw- ,al of the ingot, by a circular crown 39 acting to connect the end 220 of the crystallizer 20 to the tubular sleeve 30.
  • the annular chamber 36 made in the end of the ingot mould 10 facing the feed of liquid metal comprises at least . one outlet (not shown in the figures) for the cooling liquid. and communicates with one end 133 of the interspace 33 through a circular crown 40, which is provided with ducts 42 and also acts to connect the end 120 of the crystallizer 20 to the tu. bular sleeve 30.
  • the ducts 42 in the circular crown 40 consist of lengthwise holes 43 opening into the chamber 36 and communicating . behind the flange 24 with hollows 44 obtained by machining radial grooves on the surface of the circular crown 40 cooperating with the back of the flange 24; said grooves communic-. ate with the end 133 of the interspace 33 formed by the jacket 32 and by the crystallizer 20 and are able to bestow on the . cooling liquid a speedy passage between wide cooling surfaces.
  • sealing ring 25 made of a thermoplastic material or like ma-. terial is envisaged which is able to ensure a perfect seal . for the connection between said elements.
  • At least one seating 48 able to lodge a thermocouple . suitable for monitoring the temperature of the end 120 of the crystallizer 20 is comprised in the end of the ingot mould 10 facing the feed of liquid metal.
  • the path of the cool-. ing liquid is as follows: after having been introduced through at least one intake into the annular chamber 36, the cooling. liquid is distributed through the holes 136 into the end 233. of the interspace 33 and then pursues its action to cool the. crystallizer 20 along the whole interpsace 33; thereafter it. passes quickly through the ducts 42 and removes a considerable amount of heat from the end 120 of the crystallizer 20, afterwards running into the annular chamber 36, in which there is. at least one discharge outlet for said cooling liquid.
  • the shapes, sizes and proportions can be changed and . the parts can be connected together with screws, welding or . by any other desired connecting means; the cooling liquid can be made to circulate in the opposite direction to that shown; different developments and conformations can be visualised . for the ducts 42 or interspace 33 within which the cooling . liquid runs without departing thereby from the scope of the . solution of this invention.
