Description
Technical field
The utility model belongs to the equipment configuration field that flame melt method manufactures corundum system crystal, is specifically related to a kind of flame melt method crystal growth equipment.
Background technology
The industrial ruby of scale operation, sapphire manufacture method many employings flame melt method, its technological process is as follows: be contained in the powder in interior hopper, because hand hammer periodically beats spring piece, make whole interior hopper produce the powder of vibration and unrestrained lower inside, the weight that the whereabouts quantity of powder can be beaten by changing hand hammer regulates.Oxygen passes into from inside and outside hopper gap, and hydrogen is passed into by material guiding pipe outside sandwich, and hydrogen or oxygen gas mixes combining combustion at mixing section place, produces the high temperature of more than 2000 DEG C at flame kernel place.The powder fallen from hopper is fused into small droplets by oxyhydrogen flame, and trickle down on the melt surface of seed rod top crystal seed, crystal seed slowly gets off with jacking system, puddle is made to drop to the slightly low region of temperature and crystallization, but keep the smelting zone that melting top has 1-2mm thick, and control on certain position, like this, crystal is just slowly grown up at crystal seed place.The speed of growth of crystal depends on powder supply quantity, and the diameter of growing crystal depends on oxyhydrogen flow, flame profile and crystallization position, and the key of whole technique keeps the stable of gas flow, blanking velocity, crystallization position and close fit to each other.
