Definitions

  • the apparatus includes a tilting trough which is arranged between two or more casting wheels and which may be tilted to direct the casting melt into a selected one of the casting molds of the associated casting wheel.
  • the dosed amount of melt is first weighed after it is delivered. from a furnace into a dosing device which is lined with refractory material. The dosed amount is fed under pressure from the dosing device into the trough for delivery to the casting mold.
  • This invention relates in general to the construction and operation of casting devices, and in particular to a new and useful method for the production of large number of copper anode plates using casting wheels having individual casting molds which are filled successively with molten copper as the casting wheels are indexed and to an improved apparatus for effecting the casting of the plates.
  • anode plates can be cast using casting wheels with a very large diameter because it is assumed that the output of these casting wheels meets the metallurgical requirements of casting and cooling.
  • the path which a circumferential point covers on a casting wheel and the speed of rotation of the casting wheel is determined by the time that is required for casting, accelerating and decelerating. Movement of the casting wheel during the casting is not possible.
  • a desirable characteristic for an anode plate which is cast is a uniform plate thickness. The inflow of copper melt and the distribution of the melt in the casting mold must therefore not be impaired by acceleration or deceleration.
  • the known principals are abandoned in solving the problem by pouring alternately in short intervals specific quantities of melt from a single source and into at least two casting wheels so that one casting wheel may continue the turn as long as the operation still takes place in the other casting wheel.
  • the principle of the invention comprises a method and apparatus for ensuring that casting can be carried out by pouring the melt material in one casting mold of one casting wheel while the other casting wheel is being moved so that the intervals of operation of the one casting wheel are used to cast in the other casting wheel.
  • any minor time loss which is still possible can only comprise providing a safety time margin for the entrance of the casting jet into the casting mold shortly after the latter has come to a standstill.
  • very large casting wheels were not required and that higher outputs can be achieved with smaller casting wheels.
  • the casting operation of the invention relates particularly to casting outputs which may be expressed in tons per hour.
  • Another aspect of the invention comprises the controlling of the supply for dosing the melt material by weighing the total amount available for dosing and keeping constant the available amount of melt from which the partial amount has to be separated. Dosing errors can therefore: be reduced to a greater extent so that the desired exact constant amount is cast for the production of anode plates of uniform thickness. Additional advantages are obtained during the introduction of the dosed amount in short intervals if the total amount available for the dosing can be kept constant.
  • the inventive construction has the special advantage that copper which has already been cast is not displaced during the acceleration of the casting wheel by the accelerating force in the casting mold as long as the material is not solidified.
  • the plant for carrying out the method is so designed that a tilting trough is arranged between two or more casting wheels which are equipped with a minimum number of casting molds.
  • the tilting trough can be inclined toward a selected one of the casting wheels so that it is supplied with a controlled amount of melt.
  • the dosing device with the melt contained in it can be weighed and it is connected through troughs with one or several melting furnaces. Since the space requirements for the use of small casting wheels is less, improvements may be obtained in this respect also.
  • the minimum number of casting molds leads to a smaller casting wheel diameter and a lower structural weight. A lower weight of the revolving casting machine results in a shorter operating path because of the reduced diameter. Since the molds lie on a smaller radius the operating speed is reduced.
  • the driving power requirement of each small casting machine is in addition for example 5.5 kw. compared to 2] kw. in the large machines. Hence ll kw. for two small drives maybe sufficient due to the fact that the driving outputs do not increase linearly with rising weight.
  • the construction of the tilting trough for connecting the dosed quantity of melt to the individual casting molds of each casting wheel in succession is an important feature of the inventive construction. Since only small periods are required for the inclination of the trough and small forces are sufficient for reversing the flow of the melt the construction of the trough in combination with the vessel for receiving the dosed melt and weighing it is important.
  • the dosing device is such that it may immediately register the weight of the melt and it insures a constant supply of the melt. This means that the tilting angles for the delivery of the material from the dosing vessel to the casting molds may be always constant.
  • the kinematics of the flow process ensure constant pressures and velocities within the melt and therefore they ensure constant times during the acceleration of the dosed amount.
  • the smelting furnace can comprise a hearth type furnace having a tilting drive motor which can be switched by means of a control impulse connected to the weighing measuring device.
  • the tilting of the furnace in intervals is effected in the rythum of the melt required for the dosing device.
  • a further object of the invention is to provide a plant for casting plates such as copper anode plates which comprises a plurality of rotatable relatively small sized casting wheels having a plurality of casting molds therein and having openings adjacent the periphery for each mold, and including means for delivering a molten material into a vessel for continuously supplying the vessel with a doseable amount of the melt and including a delivery trough connected between the vessel and each casting wheel and which is mounted for movement to deflect the melt material from one casting wheel into the other for selectively filling the casting molds of the casting wheel.
  • a further object of the invention is to provide a casting apparatus which is simple in design, rugged in construction and economical to manufacture.
