Adhesive 10-30 parts.
The preparation of described outer layer coating just goes to be the calcium carbonate powder, calcirm-fluoride powder, oxygen for taking particle diameter in 100-500um
Change potassium powder, nickel powder, alumal powder, carbon ferrochrome powder, ferrotungsten powder, molybdenum-iron powder, stir after mixing,
Add silicate adhesive and a small amount of water stirs, the painting pressure technique after stirring routinely is coated in core wire surface, dries
After produce.
In the welding wire of above-mentioned welding elevator guide shoe plate, described outer layer coating mainly includes calcium carbonate 16 by weight
Part, 8 parts of calcirm-fluoride, 5 parts of potassium oxide, 3 parts of nickel powder, 10 parts of alumal powder, 23 parts of carbon ferrochrome, ferrotungsten 12 are divided, 6 parts of molybdenum-iron,
20 parts of silicate adhesive.
Beneficial effects of the present invention：Compared with prior art, the present invention has been carried out excellent to the composition of the outer layer coating of welding wire
Choosing, the welding wire postwelding with this outer layer coating do not ftracture, improve yield rate, reduce waste, ensure that quality.
