Description

technical field

[0001] The invention relates to a smelting furnace for melting alloys, more particularly to a water-cooled copper mold laser smelting furnace using laser beams as a heat source for smelting alloys and a method for smelting ingots. Background technique

[0002] Currently commonly used alloy melting furnaces are:

[0003] 1. Water-cooled copper crucible vacuum arc melting button furnace

[0004] The smelting process of this furnace is complicated, and it needs repeated vacuuming, repeated turning and smelting for more than 3 times, serious burning and volatilization of alloy elements, large changes in chemical composition and difficult to control, and long smelting time; there is pollution of tungsten alloy electrodes to the alloy; alloy composition and structure The uniformity is low; only button-shaped samples can be smelted, and peg-shaped and long-bolt ingots cannot be smelted.

[0005] 2. Ceramic refractory material and graphite crucible alloy induction ...
