Title:
PREHEATING METHOD FOR LADLE FOR MOLTEN ALUMINUM AND PREHEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/056287
Kind Code:
A1
Abstract:
Provided are: a preheating method for ladles for molten aluminum whereby the inside of a ladle for molten aluminum can be efficiently preheated, reduction in the effective volume of the ladle can be minimized even if the ladle is repeatedly preheated and used, and contamination of the melt by non-metallic inclusions can be reduced; and a preheating device using said method. This invention is characterized by a preheating pipe (26), comprising a heat-resistant metal thin plate material, enclosing a flame (30) from a burner (24) attached to an opening (16) of the ladle (12) for molten aluminum, in a preheating method and preheating device for the ladle (12) for molten aluminum, whereby the inside of said ladle (12) is preheated by the flame (30).
