The improvement of water-glass sand, and a total of collapsibility Research


Surface of the cut piece muntjac gangrene Ⅱ pit down the dark cracks and Wei coexistence) play the nine direction of motion 4. Yun Qu leaves when: 160h formed Ju leaves 1. Mentioned topographic characteristics must wear closely related to its microstructure Fu. Data _3] pointed out that the low-ming,Moncler online, cast iron carbide eutectic lamellar orientation in different hardness is different,Moncler jacken, a total of two cross-section l hardness (HVI425) Ming crown height r longitudinal section (HV935), the carbonation leaves things most of smaller lath well as alignment, the higher the hardness of the crystal surface is at r measures surface l:, and the smaller the gap carbide asked. The physical characteristics of the time base to better protection from the sword,moncler daunenjacke, thus cutting the substrate to be traces of lighter projectiles. Leaf water towel matrix is martensite. With high strength and hardness, the election of the carbide x can be more effective support for pro play, making the matrix of carbon buried in something else not easily be chipped or broken projectile. LI in the tadpole can be seen at the arrow was still very broken carbide body protection without loss. Room, due to the improvement of carbide morphology and distribution, child and raised \800 × leaf removal base line photo: l60h, 4% nitric acid corrosion of alcohol by the l: the above we can see that the microstructure of the fJU leaf blade characteristics and SD is not deleted, the role of the projectile when it's cut for the film and the impact generated by j mill rescue, cutting the lines and neat hole in the degree of I: SD Department of leaf than the much lighter and therefore,ugg prezzo, IU shaking the leaves to make life much higher than the SD leaves i, IV, conclusions often chip l j j blade failure in the form of three Qi slot fragment species and uniform wear erosion, loss of teaching the first two leaves 75% of the total, to l:, life short (10 - 4oh). The main reason is the leaf internal shrinkage. inclusions casting Aunt depression caused; uniform wear failure 235% of the total leaf, optional life 50h. trial run to leaf 300330h, no fragments or towel erosion trench failure, and the thickness of the wear value than the average small to defend more than 3 leaves morphology of the surface wear in the grinding, often leaves both leaf and trial suspect the presence of large cutting grooves. The former is long and deep trench,ugg italia, which is short and shallow; often formed by Hj J leaves cracks and spalling of the number and size of pits leaves much larger than the trial. 4 trial leaves the high matrix hardness, carbide morphology and distribution is reasonable, to significantly improve the wear resistance of reference folder ...
