<p>PURPOSE: To provide a continuous crystalization-furnace in which no thermal and time loss are attained, a superior universal application is obtained and a small-sized formation can be realized at a low cost. CONSTITUTION: A plurality of electrical heaters 3 are arranged in a spaced-apart relation in a vertical direction around a vertical passing hole 1a formed in a furnace body 1. These heaters 3 are controlled independently or in cooperation with each other by a control part 16. A soaking box 4 having prosthetic appliances stored in it is loaded in sequence in a passing hole intermittently by a loading means 5 through a lower end opening. The soaking boxes loaded are transported in sequence upwardly in an intermittent manner and they are heated by the electrical heaters in accordance with a predetermined crystalizing program at the stopped position and the supplementing elements in the boxes are crystalized.</p> |
