After less than 200 DEG C, the spoon in punching block is taken out（Spoon surfacing now but rough）；
Then using mechanical cold repair method, edge and matched moulds vestige to spoon carry out reconditioning, are allowed to smooth；
(3) the smooth treatment in spoon surface
Support possesses use
30cm long, width 30cm, the bloom of thickness 10cm is taken to have as support；Bloom upper surface is provided with a spoon type cavity, can hold spoon and exist
Consolidated in cavity and kept flat；
Heat
During spoon after reconditioning kept flat into the cavity of tool of starting going to a nursery, then will support tool even spoon is put into electric furnace, heating-up temperature
When reaching 750-800 DEG C, constant temperature 40-60 minutes；
Move back temperature
Electric furnace is cooled to 700-720 DEG C, constant temperature 5-10 minutes；
The temperature that plunges treatment
The spoon in electrothermal furnace is pressed from both sides out using steel clamp tool, is cooled down 1-2 minutes in input normal temperature mineral oil；Spoon goes out from electrothermal furnace
To the time control of mineral oil is entered at 1-3 seconds, the mineral oil viscosity for using is 120Pa.S to stove, and flash-point is 200 DEG C；
Cleaning
Have with steel clamp and spoon is taken out from mineral oil, be put into oil removing cleaning fluid, drift in clear water is put into after manually cleaning
Wash, to product as drying naturally after rinsing, the smooth domestic glass ceramics spoon in surface is obtained.
The normal temperature is 20~35 DEG C.
Obtained domestic glass ceramics spoon surface of the invention is smooth, and matrix surface compact structure, bearing stress enhancing is produced
Product reach in use health, be readily cleaned, wear-resisting, impact resistant and other effects.
