Summary:The invention provides a smelt outflow nozzle that the melt has little wet rising on the nozzle when manufactures micro spherical particle or preformed materials, and the glass that has wet rising on the front end of the nozzle is easily to completely removed. The smelt outflow nozzle (1) outflows the smelt from the front end (2) and has a flow passage (6) of the smelt, comprising an inner surface (31) facing to the flow passage (6), an outer surface (32) covering the inner surface (31) and an end face (21) connected with the inner surface (31) and the outer surface (32) at the front end (2). The mean roughness (Ra) of center line of the outer surface (32) is less than or equal to 1.6 m.
