?n timpul utiliz?rii moar? Raymond, nu se adaug? lubrifiant sau ulei de lubrifiere o perioad? lung?, dar selec?ia lubrifiantului sau a uleiului de lubrifiere ad?ugat este gre?it?. Dac? umplerea nu este corect?, ma?ina va fi deteriorat?, iar deformarea ?i instalarea rulmen?ilor nu vor fi corecte. Rulmentul de m?cinare se deplaseaz? spre exterior, apas? pe inelul de m?cinare, determin?nd lama s? ?mping? materialul ?ntre rulmentul de m?cinare ?i inelul de m?cinare. Inelele de m?cinare ale moa?tei Raymond, r?cirea prin solidificare a lingourilor de o?el, contrac?ia volumetric? ?i, ?n final, piesele din metal lichid solidificat nu pot fi ad?ugate.
     
Gaura mare, concentrat?, se nume?te cavitate de contrac?ie. Spa?iul mic ?i dispersat se nume?te osteoporoz?. Suprafa?a sa intern? este aspr?, iar ?n jurul ei exist? numeroase impurit??i ?i micropori. Datorit? legii expansiunii ?i contrac?iei termice, contrac?ia este inevitabil?; dimensiunea ?i pozi?ia sau extinderea la lingou reprezint? o imperfec?iune a corpului. Pentru a preveni apari?ia acestor defecte, le putem elimina complet din surs?.
     
moar? Raymond's grinding roller grinding ring fails to escape the gas during metal solidification process. The metal is formed in a small hole, the ultrasonic wave has a high reflectivity, and because of its substantially spherical or elliptical shape, the porosity of the steel ingot is forged. Or after rolling, it is flattened into area type defects and found to benefit from ultrasonic testing. Ultrafine grinding of the grinding ring during the reaction of the grinding ring, or the addition of some components of the metal parts of the material to form incompletely molten metal inclusions, such as high density, high melting point, such as tungsten, molybdenum.
