我厂国产真空气淬炉料筐为随机带的由φ10mm不锈钢(1Cr18Ni9Ti)焊制而成的网格状筐,其网眼尺寸为100mm×80mm。使用几次后,筐底平面网格即出现不同程度的弯曲变形,造成模具与筐底平面由最初的线接触,发展到局部点接触,局部悬空。在加热过程中容易引起模具因自重而产生的热变形。 为解决这一问题,我们制备了形状、大小与淬火筐底相同的厚石墨板(其上均布大径通风孔),将其
Our factory made of vacuum gas quenching charge basket for the random belt by φ10mm stainless steel (1Cr18Ni9Ti) welded grid-like baskets, the mesh size of 100mm × 80mm. After using several times, the bottom plane grid will appear different degrees of bending deformation, resulting in the mold and the bottom plane of the plane from the initial line of contact, the development of the local point of contact, partial dangling. In the heating process easily lead to die due to weight and heat distortion. In order to solve this problem, we prepared a thick graphite plate of the same shape and size as that of the quenched basket (on which large diameter vents are uniformly distributed)
