Alloy steel castings will be damaged even if they are used for a long time. At this time, they need to be replaced. When replacing alloy steel castings, there are many things to pay attention to for smooth use in the future, otherwise it will affect the normality of alloy steel castings. use.
As some deformed alloy steel castings are not universal, even if the deformed products of the same model are produced, they need to be matched separately because their parts are not universal, and suitable and targeted alloy steel castings should be selected based on various factors.
Because the surface of alloy steel castings is coated with anti-rust paint, it must be cleaned up before assembly, especially for some precision parts, so as to avoid hidden dangers. When buying alloy steel castings, you must pay attention to the quality of the parts and identify fake and inferior products; carefully check whether the parts have rust spots, cracks, deformation and other defects, and whether the surface dimensions meet the requirements.
At the same time, some matching parts should be replaced in pairs. For example, when replacing gears, you can't just replace the more worn one; when replacing the double-row sleeve roller chain in the transmission box, you should also replace the master and driven sprockets in pairs. ; When replacing the cylinder liner, the piston and piston ring should be replaced at the same time.
The above are the details to pay attention to when replacing alloy steel castings. Only by doing this, can the parts be used normally after replacement without affecting their original good condition, so we need to keep these essentials in mind.
