Definitions

  • the invention relates to a device for casting strands of metal, in particular steel, with a material supply container, via the pouring the liquid metal is placed on the upper run of a circulating conveyor belt, wherein the conveyor belt of a circulating between a first and a second guide roller heat-resistant thin Band exists that is trough-shaped after receiving the first pulley and in the region of the pouring nozzle for receiving the liquid metal and near the second pulley again assumes the shape of a flat band.
  • Such a device is known from Japanese Publication 59147755A.
  • the trough shape of the belt is achieved by along the conveying path between the two pulleys arranged acting on the tape, vertical and horizontal conveyor rollers.
  • the band usually a steel band used here
  • the different stresses on the band across the width means that no economic service lives are achieved.
  • the object of the invention is therefore to design the device so that the band stresses are reduced and are moderated moderately.
  • new materials for the strip material are to be used due to the lower and more uniform strip loading.
  • the length of the inlet or outlet section of the geometry of the trough profile should be adapted to adjust the size of the crown targeted. The efficiency of the casting process should be significantly increased.
  • At least one of the deflection rollers is convexly convex.
  • the stress of the band can be made uniform, so that this has a positive effect on the service life.
  • Print medium is variable.
  • a profiled cavity is present in the roller shell.
  • Deflection pulley is smaller than that of the second pulley.
  • the crowning can be calculated on the basis of the geometry of the trough profile. With different trough profile over the length trough to adapt to the shrinkage of the casting profile, the middle trough profile is used for the calculation.
  • FIG. 2 shows a cross section through the trough mold
  • Figure 4 shows the trough cross section for the calculation of the temperature influence.
  • the crowning is a function of the respective band length Le (inlet length) or La (outlet length) between the deflection roller and the trough profile or vice versa, the bandwidth BB, the trough width B T , the trough height H ⁇ and the trough profile wherein for the calculation auxiliaries rectangular longitudinal shape is assumed.
  • the calculation of the crowning can be done for each point of the pulley between the points A and B of the trough profile with the coordinates X and Y and the length Le (a) for half the bandwidth B B between the points C and D.
  • the calculation of the crowning must be done for the inlet and outlet side.
  • the calculation of the different tape length due to the different temperature distribution over the bandwidth can be calculated in a simplified manner according to the formula given.
  • the temperature profile is calculated over the bandwidth according to the casting parameters.
  • superposition can be used to calculate the optimal crowning of the deflection rollers for a uniform tensile stress over the belt width for a given trough profile (casting format) and temperature profile.
  • the crowning of the first deflection roller is smaller than that of the second deflection roller.
  • the crown should be changeable, e.g. through a pressure medium.
  • a profiled cavity may be present for the pressurization on the roller shell.
  • the inlet and outlet length should each be greater than 500 mm.
  • the max. Inlet or outlet length is selected so that the crowning due to the trough profile is not greater than 2%.
  • the band is formed by the deflection roller continuously over the distance Le (a) to the trough profile or to the flat band.
  • thermoshock-resistant alloy based on CuNi, Fe.
  • the strip material may consist of a single- or multi-phase Cu alloy or of a nickel-based alloy.
  • the trough profile should have a curved course, preferably symmetrical.

Abstract

La présente invention concerne un dispositif conçu pour couler des barres de métal, notamment d'acier, lequel dispositif comprend un récipient d'alimentation en matière qui permet, par le biais de sa buse de coulée, de charger le métal fluide sur le brin supérieur d'une bande transporteuse en circulation. La bande transporteuse est composée d'une bande mince résistante à la chaleur qui circule entre une première poulie de renvoi et une seconde poulie de renvoi, laquelle bande est façonnée en forme d'auge après la première poulie de renvoi et dans la région de la buse de sortie afin de recevoir le métal fluide et reprend la forme d'une bande plane à proximité de la seconde poulie de renvoi. Afin de réduire les contraintes sur la bande, au moins une des poulies de renvoi est bombée de manière convexe.
