Abstract

A laser furnace for smelting different alloys, the metal or alloy difficult to smelt, pure alloy, etc is composed of furnace body, copper mould, cooling water unit, atmosphere protector, upper furnace body and top cover, and features the laser beams are used as heat source for smelting alloy.

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 ...
