摘要： A scraping-wheel drill bit with a bit body configured at its upper extend for connection into a drillstring, comprising: a bit body (1) with at least one bit leg (3), and at least one scraping-wheel (2) set with a cutter-row (4). The scraping-wheel (2) is mounted for rotation on the corresponding bit leg (3) with a large angular deflection α which lies in the range of 20°≦|α|≦90°. The cutters on the scraping-wheel break rocks by means of successive scraping, forming a spiral-like tracks on the bottomhole, thus achieving high rock-breaking efficiency, even wear, high cooling performance, and a longer service life for the cutters, bearings and the drill bit.

摘要： A composite drill bit with a bit body configured at its upper extend for connection into a drillstring, comprising: a bit body (1) with at least one bit leg (3), at least one scraping-wheel (2) set with a cutter-row (4), and a set of cutters fixed thereon. The scraping-wheel (2) is mounted for rotation on the corresponding bit leg (3) with a large angular deflection α in the range of 20°≦|α|≦90°. The cutters on the scraping-wheel break rock by means of successive scraping, forming a cross-cutting area on the bottomhole accompanied by the cutters on the fixed cutting unit, thus achieving high rock-breaking efficiency, even wear, high cooling performance, and a longer service life for the cutters, bearings and the drill bit.

摘要： Methods for the improvement of mechanical properties of aluminum can stock materials. In one method, an aluminum alloy is cast into an ingot, heated at an elevated temperature to homogenize the alloy, hot rolled at an elevated temperature to form hot band material and cold rolled to final gauge. After the heating step, the alloy is hot rolled immediately to minimize the cooling of the alloy between the heating and hot rolling steps.
