A kind of hot extrusion steel tube plug preparation technology of lubrication protection coating, in turn includes the following steps,
The first step, is mixed to get mixture A by following components progress proportioning by weight：0~38 part of bismuth oxide, lead oxide
0~38 part, 0~3 part of boron oxide, 0~1 part of zinc oxide, 2~6 parts of silica, 0~1 part of aluminum oxide, 0~1 part of calcium oxide, oxygen
Change 0~1 part of magnesium, 0~0.5 part of titanium dioxide, 0~0.5 part of iron oxide, 2~5 parts of potassium oxide, 0~3 part of sodium oxide molybdena；
Second step, mixture A is put into melting furnace and melt obtaining fused mass；
3rd step, is clarified fused mass, is homogenized, removes bubble removing；
4th step, glass dregs are formed using water quenching is broken to the fused mass progress after clarification；
5th step, auxiliary agent, water and binding agent are added in glass dregs and is sufficiently mixed obtains mixture B in proportion：Glass
20~60 parts of slag, 0~20 part of auxiliary agent, 20~60 parts of water, 20~70 parts of binding agent；
6th step, to mixture B ball millings 48~96 hours, and crosses and hot extrusion steel tube plug is obtained after 200 mesh sieves lubricates
Protective coating.
Preferably, the auxiliary agent is kaolin or bentonite.
Beneficial effects of the present invention：
The hot extrusion steel tube plug is sprayed at hot mandrel surface with lubrication protection coating and is firmly bonded, steel billet reaming procedure
Middle glass lubrication coating plays a part of to lubricate and protects plug, after the completion of extruding, and when plug cooling, the glass lubrication on its surface is applied
Layer, can be peeled off automatically.This glass lubrication coating has filled up the blank of hot extrusion steel tube plug thermal spraying, with obvious economic effect
