摘要： PURPOSE: To prepare small-sized zinc shots suitale for blasting consistently with good yield, by allowing molten zinc to drop through a nozzle from a sump into water under controlled conditions of temperature and depth of molten metal, nozzle size, distance between nozzle and surface of water, temperature of water, etc.
CONSTITUTION: A ceramic nozzle 15 with an orifice diameter of 0.3W0.6mm is provided at the bottom of a sump 13 in a tank 10 which is divided into a molten metal pouring chamber 12 and the sump 13 and a molten zinc heated to 540W 600°C is supplied to the tnak 10 so that the depth of the molten metal may be 30W60cm. Then the molten zinc is allowed to drop through the nozzle 15 into a water tank 1 which is filled with water at 30W50°C to such a level that the distance from the bottom end of the nozzle 15 to the surface of water may be 10mm or smaller. The molten zinc is allowed to cool and solidify and the zinc shots thus formed are led into a taking-up chamber 13 along an inclined bottom wall 4 and are taken out into a collecting container 5.
