Description
Technical field
The present invention relates at a kind of non-crystalline material crystallization and thermal treatment device and method more particularly to a kind of burner hearth method crystallization heat
The device and method for managing non-crystalline material.
Background technique
It is well known that non-crystalline material performance quality and crystallization and thermal treatment temperature have a substantial connection, at current non-crystalline material heat
The processing for managing crystallization is heated in big burner hearth, and general to use about 60 centimetres of furnace diameter, high about 50 centimetres of burner hearth in this way
In one big furnace, furnace central temperature and furnace peripheral temperature difference are all larger, and the upper temp of furnace and the temperature of furnace bottom go out to have big
The temperature difference.Due in crystallization different location there are the big temperature difference, the performance of product be impossible to it is completely the same, to produce
The consistency of performance of product is good, and the temperature difference that must just control each position in furnace is no more than 30 DEG C, is heat-treated big burner hearth at present,
Want that it is impossible for reaching this one small temperature difference.Big furnace treatment reason crystallization heating time is long at present simultaneously, generally at 5~6 hours, because
The oxidation of this amorphous product in order to prevent, heating furnace must lead to protective gas or vacuumize, therefore the heat treatment crystallization energy at present
Consumption is big, and more major product consistency of performance is poor.
