Zein dira errodamendu linealen tratamendu termikorako errendimendu probak egiteko arauak?

2019-03-07

Baloia lineako errodamenduak ekipamendu mekaniko ugaritan erabiltzen dira, eta errodamenduak eskatzen dituzten baldintzak gero eta zorrotzagoak bihurtzen dira, eta errodatzearen errendimendua gero eta gehiago bilakatu da.

 

Kojineteak aukeratzerakoan, kojineteak kontuan hartu behar dira; zahartzearen koipea, koipea, higadura-bizitza, higadura-erresistentzia, zarata baxua ere aztertu behar dira.

 

1) Before heat treatment, check whether the heat treatment equipment, auxiliary equipment, instruments, etc. are qualified and normal, and whether the temperature difference between the furnaces is within the specified range (±5 Â °C);

2) Sanding or rinsing should be done before the furnace is installed. There should be no oil, dirt and dirt. The alloy grades should not be mixed;

3) The castings whose shape is prone to warpage should be placed on a special chassis or bracket, and the suspended cantilever portion is not allowed to be suspended;

4) Puzgarriak hartzearen funtzionamendua egiaztatzeko taberna bakunak edo zulatuak elkarrekin tratatuko dira labeen errendimendua islatzeko;

5) Bero kontserbazio aldian, labe tenperatura edozein momentutan egiaztatu eta zuzendu egin behar da tokiko tenperatura altuak edo erretzea saihesteko.

6) When the power cannot be recovered after a short time after power failure, the castings in the heat preservation shall be quickly quenched, and then restored to normal, then furnace, warm and heat treatment;

7) Castings that have been quenched in a nitrate tank should be rinsed with hot water immediately after quenching to eliminate residual salts and prevent corrosion;

8) The deformation of the casting after quenching is found and should be corrected immediately;

9) Parts to be aged shall be aged within 0.5 h after quenching;

10) If the performance is found to be unqualified after heat treatment, the heat treatment may be repeated, but the number of times shall not exceed 2 times;

11) Heat treatment shall be carried out according to the heat treatment process of the shape, size and alloy characteristics of the casting.
