摘要： Clad steel roiled section suitable for reinforcing concrete is disclosed, which is produced from a bimetallic ingot comprising a basic material containing a group of alloy elements including Si and Al, and a surface layer of a ferritic or austenitic stainless steel containing a group of alloy elements including Cr and Ni, by hot rolling the ingot to an intermediate billet and a rolled section, and subjecting the rolled section to heat treatment. A feature of the reinforcing clad steel rolled products is that the basic material is steel containing, in percent by weight, from 1.0 to 5.0 Si and from 0.1 to 5.0 Al, with the proviso that 3.0null(SinullAl)null6.0. The reinforcing clad rolled products exhibit superior mechanical strength and impact toughness, improved corrosion resistance and high bond strength between the layers and with concrete. The clad rolled products are produced by a method involving making a bimetallic bar with a stainless steel surface layer, hot rolling the bar in several passes by calibrated rolls, the final rolling being effected by calibrated rolls with corrugated surface observing the relationship: 1 H 0 null null d null 1 where Ho is the maximum depth (height) of corrugations on the roll surface, d is the bar diameter, null is the relative thickness of the stainless layer.

摘要： A method for setting a roll gap of sinusoidal corrugated rolling for a metal composite plate includes steps of: determining entrance thicknesses, exit thicknesses, a width, and a rolling temperature of a difficult-to-deform metal slab and an easy-to-deform metal slab; detecting a roll speed and an entrance speed of a metal composite slab, obtaining a roll radius and friction factors; determining parameters of a sinusoidal corrugating roll and a quantity of complete sinusoidal corrugations on the sinusoidal corrugating roll; then calculating a time required for a complete corrugated rolling; calculating a rolling force at any time during the sinusoidal corrugated rolling of the metal composite plate; and calculating the roll gap S of the corrugated rolling at any time according to the rolling force F, and configuring a rolling mill to have the roll gap S according to an actual rolling schedule before normal production.

摘要： A spring washer improves resistance to loosening of fasteners tightened thereon. The spring washer is stronger than prior art devices. On the upper and lower surfaces of the spring washer, approximately 1/5-1/4 of the width inward from the outer perimeter is formed without V-shaped grooves. The remaining flat portions are formed with V-shaped grooves in various patterns. These V-shaped grooves increase the coefficient of friction and resist loosening of the spring washer.

摘要： Billets of hot steel are hot rolled through a series of rolling stands to form an elongated flat. This flat is first worked to a predetermined thickness and width and then subjected to an edging pass at a succeeding stand. The edging pass is comprised of a pair of rolls having spaced apart, aligned grooves to receive the flats. The groove in one of the rolls is provided with a plurality of holes having certain characteristics. The depths of the roll grooves, the distance they are spaced apart, the depth and other characteristics of the holes provided in the one grooved roll and the widths of the roll grooves are all adjusted with respect to the predetermined dimensions of the flats entering the edging pass so that desired serrations are imparted to the flat as it passes through the edging pass. A final flat pass may be utilized to finalize the dimensions of the finished, serrated flat. The holes are cut into the roll groove by electric discharge machining. Care is given to the control of the shape of the flat before and after it enters the edging pass. The serrations, however, are imparted to the flat as it passes through the edging pass.
摘要翻译：热轧钢坯通过一系列轧机架进行热轧，形成细长的平面。首先将该平面加工成预定的厚度和宽度，然后在随后的台架上进行磨边。边缘通过一对具有间隔开的对准的凹槽以接收平面的辊。一个辊中的槽设有多个具有某些特性的孔。辊槽的深度，它们间隔的距离，设置在一个凹槽辊中的孔的深度和其它特性以及辊槽的宽度都相对于进入边缘的平面的预定尺寸进行调整通过，使得当平面通过边缘时，所需的锯齿被赋予平面。可以使用最终的平面通过来完成成品的锯齿状平面的尺寸。通过放电加工将孔切割成辊槽。注意在进入边缘通道之前和之后对平面形状的控制。然而，锯齿在穿过边缘时被赋予平面。
