Vendors would cooking oil refined oil equipment squeezer spray welding materials
Oil refined oil equipment squeezer for carburizing and quenching, surface hardness HRC58-64, the depth of hardening layer of 1.5-1.9 mm.To improve carburization cooking oil refined oil service life of the equipment squeezer, must choose wear resistance is higher than the carburizing and quenching layer of wear resistant materials.
Abroad with surfacing drill a chrome a tungsten alloy repair large edible oil refined oil equipment squeezer, this alloy is better than in less than 8000 c temperatures carburizing and quenching layer more excellent wear resistance.Relevant research at home and abroad of edible oil refined oil equipment technical data showed that the edible oil refined oil equipment squeezer working temperature at 150-150 - c, can still be considered wear at low temperature range.palm oil refinery plantᄃ
Thermal spray welding since the metal is widely applied in the surface protection of wear-resistant alloy, in less than 5400 c temperatures with high hardness and wear resistance.Using oxygen acetylene flame spray welding method, in surface welding layer is easy to get extremely smooth level off, in the cooperate machined parts, if not for machining after welding, also can meet the use requirement, to avoid the surfacing drill a chrome a tungsten alloy machining problem.
As the research of edible oil refined oil equipment squeezer screening of spray welding metal, using rubber wheel abrasion tester to 20 cr steel gas, liquid carburizing and quenching specimen and domestic several since the metal wear comparison test, the results show that under the two kinds of sand grits, tomb of nickel and iron base since the test metal abrasion resistance are higher than 20 cr steel carburized layer several times, the Nit nickel-based alloy wear resistance is best, 7 ~ 8 times higher than that of carburizing layer.More cheap Fe1 iron base alloy is weightlessness.But wear resistance...
