Equipment of oily refined oil of edible of oil press manufacturer extracts material of snail gush solder

Equipment of oily refined oil of edible of oil press manufacturer extracts material of snail gush solder

Equipment of edible oily refined oil extracts snail surface to quench for cementite, hardness HRC58-64, quench millimeter of layer deepness 1.5-1.9. Want to raise equipment of cementite edible oily refined oil to squeeze the service life of snail, must choose cementite of wearability prep above to quench the wear-resisting material of the layer.

Abroad uses v to get one chromium equipment of large edible oily refined oil extracts rehabilitate of one tungsten alloy snail, this kind of alloy is in be less than 8000C temperature next having quench than cementite a more superior wear-resisting performance. The technical material that concerns equipment of research edible oily refined oil domestic and internationally makes clear, equipment of edible oily refined oil extracts snail job temperature to be in more 150-3000C, still can consider as microtherm to wear away limits.

Hot gush solder closes from frit gold is the wear-resisting alloy that at present wide application protects at workpiece surface, in be less than 5400C tall hardness and wearability are had below temperature. Use oxygen method of solder of gush of one acetylene blaze, obtain the solder layer of very smooth level off easily in workpiece surface, in blame cooperate machine treatment place, although solder hind does not have machine treatment, also can satisfy use requirement, avoided v to get one chromium one tungsten alloy brings machine treatment difficult problem.

Extract snail to consider to choose equipment of oily refined oil of gush solder edible from fusion gold, use oak rubber tyre to wear away experiment machine quenchs to cementite of 20Cr steel gas, liquid test specimen and home undertake a few kinds wearing away contrasting experimenting from fusion gold, the result makes clear, bead is ground to fall in two kinds of sand mold, experiments nickel grave and iron base from fusion gold wearability all layer of cementite of steel of prep above 20Cr is multiple, among them wearability of alloy of Nit nickel radical is best, 7~8 of layer of prep above cementite times. The Fe1 with low price iron radical alloy although weightlessness is more. But wearability also 1~2 of layer of prep above cementite times. The tall wearability of gush seam gold basically is metallographic many carbide and boride are contained in the organization, resisted quartz wears bead effectively press with grinding 0 Ni: ?  of salty awake of rate of  of  of scull of Mi of Jian of administer Lu admire makes fun of directly the carbide that establish armour Pang catchs V1000-1800 holding the post of and boride. The metallographic organization of Fe1 alloy is austenite in all brilliant, and hardness is HV800~120. carbide and boride. These sample wear away the arenaceous without quartz grinding stripe after lens of exterior classics report magnifies, only local present some hard fragile data is special flaking indentation. And cementite quenchs the metallographic organization of the layer is martensite of tall carbon temper and graininess carbide, its hardness wears bead under quartz, reason sample wears away the surface by the furrow shape of wear stripe clarity.
