To provide light metal melting equipment of high efficiency capable of effectively utilizing collected aluminum wheels and waste tires as resources and applying the waste tires as a heat source while minimizing the use of fossil fuels.

This aluminum alloy melting equipment 1 is provided with a dry distillation gasification furnace 3 for dry-distilling the tires and generating a dry distilled gas, and an aluminum alloy melting furnace 2, the waste tires are charged into the dry distillation gasification furnace and burned without supplying sufficient air to generate the dry distilled gas, the air is supplied on the way of a dry distilled gas duct 12 for sending the dry distilled gas to the aluminum alloy furnace, and the dry distilled gas and the air are mixed in a combustion spare chamber 22, and burned in a melting furnace main body 21. A half-combustion zone of flame falls in the combustion spare chamber, and the combustion zone falls in the melting furnace main body.
