    • Disclosed herein is a manufacturing method, excellent in wire drawability, of a seamed flux-cored welding wire having both favorable feedability and low hydrogen content characteristic. The method for manufacturing a seamed flux-cored wire, comprises the steps of: drawing a tube-like formed wire including a flux filled therein using a lubricant; removing the lubricant from the drawn wire by a physical means; and coating a lubricant (coating an oil) for wire feeding on the wire surface. The respective steps are carried out in an in-line manner. In the wire drawing step, a wire drawing lubricant containing a sulfur-bearing high-pressure lubricant is used, and the overall wire drawing from the tube-like formed wire to a roughly product-diameter wire is carried out by means of a roller die.
    • 本发明公开了具有良好的进料性和低氢含量特性的接缝药芯焊丝的拉丝性优良的制造方法。 制造接缝药芯焊丝的方法包括以下步骤:使用润滑剂拉制包含填充在其中的焊剂的管状成形线; 通过物理手段从拉丝线上除去润滑剂; 并在金属丝表面上涂布润滑剂(涂覆油)以进行丝线输送。 相应的步骤以在线方式进行。 在拉丝工序中,使用含有含硫高压润滑剂的拉丝润滑剂,通过辊模进行从管状成形线到大致产品直径的丝的整体拉丝 。

    • A method for constructing a metal wire with embedded filaments or cavities therein for biomedical applications. The method includes first drilling nonconcentric apertures in a symmetrical pattern in a metal rod and then embedding filaments in the apertures. The metal rod is then drawn and thermally-treated to form a metal wire with embedded filaments therein. The filaments may advantageously provide fatigue resistance, radiopacity, and electrical conductance to the metal wire. The method optionally provides an additional step for withdrawing or removing the filaments using various methods to create cavities for cavity access within the metal wire. The metal wire may be finished to provide access to the cavities or filaments embedded therein. The cavities may then be filled with a therapeutic drug for elution inside the human body or used for passage of body fluids. An optional biocompatible coating may be disposed around the metal wire to prevent escape of the therapeutic drug before insertion into the human body. The cavities may also be filled with different materials as compared to the original filaments.
    • 一种用于构建其中具有嵌入的细丝或空腔的金属线的方法,用于生物医学应用。 该方法包括首先在金属棒中以对称图案钻出非同心孔,然后将细丝嵌入孔中。 然后将金属棒拉伸并热处理以形成其中具有嵌入的细丝的金属线。 长丝可以有利地提供对金属丝的耐疲劳性,不透射线性和导电性。 该方法可选地提供了用于使用各种方法抽出或去除长丝的附加步骤,以在金属丝内产生用于空腔进入的空腔。 金属丝可以被完成以提供对嵌入其中的空腔或细丝的接近。 然后可以用用于在人体内洗脱或用于体液通过的治疗药物填充空腔。 可选的生物相容性涂层可以设置在金属丝周围,以防止治疗药物在插入人体内之前逸出。 与原始细丝相比,空腔也可以填充不同的材料。

    • Methods and systems are provided for the continuous coating and fabrication of spiraled steel rebar product for concrete structures. Specifically, methods and systems are provided by which linear uncoated rebar is supplied to a polymeric (preferably, epoxy) powder-coating unit whereby a substantially uniform coating layer of a polymeric material is applied onto the uncoated rebar to form a linear coated rebar; and thereafter the linear coated rebar is bent into a spiraled steel rebar product. The bending unit employed to bend the linear coated rebar includes a series of bending wheels having separated upstream and downstream bending wheels and a central bending wheel which is disposed between and below these upstream and downstream bending wheels. By bringing the linear coated rebar into contact with the series of bending wheels, the rebar may be bent gently into spiraled steel rebar product without damage to the polymeric surface coating. In this regard, it has been found that such gentle bending of the coated rebar may be advantageously accomplished using bending wheels which include a rubber-like tire mounted on a rigid rotatable wheel member.
    • 为混凝土结构的螺旋钢筋产品的连续涂层和制造提供了方法和系统。 具体地说,提供了一种方法和系统,通过该方法和系统,将线性未涂覆钢筋供应到聚合物(优选环氧树脂)粉末涂料单元,由此聚合材料的基本上均匀的涂层施加到未涂覆的钢筋上以形成线性涂层钢筋; 然后将线性涂层钢筋弯曲成螺旋钢筋产品。 用于弯曲线性涂层钢筋的弯曲单元包括一系列具有分离的上游和下游弯曲轮的弯曲轮和设置在这些上游和下游弯曲轮之间和之下的中心弯曲轮。 通过使线性涂层钢筋与一系列弯曲轮接触,钢筋可以轻轻弯曲成螺旋钢筋产品,而不会损坏聚合物表面涂层。 在这方面,已经发现,使用包括安装在刚性可旋转轮构件上的橡胶状轮胎的弯曲轮可以有利地实现涂覆钢筋的这种温和弯曲。
