山东铅锭厂价正式进入600以下，弱势显现，商家也多显无奈，虽然现在山东的地区多数铅锭选厂已经能够恢复开工，但贸易商高价采购铅矿石再加工之后，铅锭价格会随着市场进行下调，按此操作的话，商家在利润方面受到了严重的挤压，因此多数选厂处在停工阶段。市场整体供需两弱，预计短期内国产矿市场多半仍将趋弱运行。就目前港口库存状况以及铅厂采购欲望来看，现货矿价反弹都是纸老虎，昙花一现的可能性高，不建议实货抄底操作。远期方面，前期BHP火灾影响，纽曼粉报盘稀少，未来纽曼粉溢价有一定上升空间;钢厂则继续港现补库，不愿拿远期美金资源，铅厂表示目前铅锭厂家利润可观，现金流充沛，而港口库存高企、品种齐全、价格也有优势。本周四美国加息是否落地对国内商品期货铅锭市场有扰动，虽连大方向仍看空，但短期震荡不可避免，选择入场点位还要谨慎。

　　How to identify whether the deformation damage it?

　　1、绳股被挤出说明铅板不平衡，绳股挤出的铅板应立即报废。此种变形是一部分钢丝或钢丝束在铅板背着滑轮槽的一侧拱起形成环状，这种变形常因冲击载荷而引起，若此种变形严重时，则铅板应报废。

　　1, is that it is not out of rope balance, strand extrusion lead should be immediately scrapped. This is a part of the side deformation of steel wire or steel beam in the lead carrying the pulley groove arch ring formation, often caused by the impact load and the deformation, if the deformation is serious, then it should be scrapped.

　　2、铅板波浪形的变形是铅板的纵向轴线成螺旋线形状。这种变形不一定导致任何强度上的损失，但如变形严重即会产生跳动造成不规则的传动。时间长了会引起磨损及断丝，出现波浪形时，在铅板长度不超过25d的范围内，则铅板应报废。

　　2, lead deformation wave is a longitudinal axis in a spiral line shape plate. This deformation does not necessarily lead to any loss of strength, but if the deformation is serious, it will produce a beat, resulting in irregular transmission. A long time will cause wear and broken wire, appear wavy, in the range of lead length of not more than 25d, then it should be scrapped.

　　3、铅板直径有可能发生局部增大，并能波及相当长的一段铅板。绳径增大通常与绳芯畸变有关，其必然结果是外层绳股产生不平衡，而造成定位不正确。

　　3, it has a diameter of the possible local increases, and can spread a long lead. The increase of the rope diameter is usually related to the distortion of the rope core, and the inevitable result is that the outer rope strands are unbalanced and cause incorrect POSTTTIONing.

　　4、绳径局部严重增大的铅板应报废。扭结是由于铅板成环状在不可能绕其轴线转动的情况下被拉紧而造成的一种变形，其结果是出现捻距不均而引起格外的磨损，严重时铅板将产生扭曲，以致只留下极小一部分铅板强度。

　　4, the diameter of the rope should be scrapped the local severe increase lead. The kink is due to a deformation of a ring in the lead can not rotate around the axis of the case was caused by the tension, the result is caused by uneven pitch extraordinarily serious wear, it will be distorted, leaving only a small part of it that strength.

　　5、当外层绳股发生脱节或者变得比内部绳股长的时候就会发生这种变形，笼状畸变的铅板应立即报废。

　　5, when the outer strands occur or become disjointed than rope should occur the internal deformation, distortion of the cage it should be immediately scrapped.
