How to calculate the taper of square billet mold copper tube?

Answer:

Taper mould molten steel solidification in the mould for the shell shrinkage gap formation, it is usually made of mould taper, the latter is defined as: a = (S - S) /S * L (3.3): taper type: Delta%/m crystallizer; S S, upper mold, a lower port length; L: Mould length. The value of the inverted taper can not be too small or too large. Not too small, too large can increase the friction force, even without a blank card steel [9]. High carbon steel shrinkage, so must use a larger inverted taper [7]. High speed casting, taper should be smaller. In this design, the taper desirable 0.96%/m, in order not to cause too much friction. The actual inverted taper is slightly smaller than the above value, approximately 0.4-0.8%/m.
A trough shaped container with a jacket or a tube arranged inside the barrel for heating or cooling a solution in a bath. The crystallizer can be used as an evaporative crystallizer or a cooling crystallizer. In order to increase the strength of crystal production, an agitator can be added to the slot. Crystallizer can be used for continuous operation or batch operation. The crystal obtained by intermittent operation is larger, but the crystal is easy to form a crystal cluster, and the mother liquor is entrapped, which affects the purity of the product. The utility model has the advantages of simple structure and low production intensity, and is suitable for the production of small batch products (such as chemical reagents and biochemical reagents, etc.).
Should pay attention to the use of approximate formula to calculate the cone half angle a/2, should be: cone half angle is less than 6 degree. Divided by length, the number 28.7 is equal to the degree.Many types of mold, according to the received method saturated solution can be divided into evaporation crystallizer and cooling crystallizer; according to the flow mode liquid circulation crystallizer and slurry denominator (i.e. liquor and crystal mixture) circular mold; according to the operation mode can be divided into continuous crystallizer and batch crystallizer.
