    • Heat radiation tubes for furnaces and the like heating devices, mainly for industrial processes.Heating can be obtained by electrical heating elements or by combustion for example of gas. The radiation tube is a circular tube having end walls, flanges etc. as required.The radiation tube is a seam-less tube made from iron-chromium-aluminum thereby greatly reducing oxide spalling and enhancing strength thereof at high temperatures. Preferably the tubes are made by extrusion whereby conditions are chosen to provide a rough surface with grooves and ridges which further improves the adhesion of the oxide layer.
    • 用于炉子和类似加热装置的热辐射管,主要用于工业过程。 可以通过电加热元件或通过燃烧例如气体来获得加热。 辐射管是根据需要具有端壁,凸缘等的圆管。 辐射管是由铁 - 铬铝制成的无缝管,从而大大减少氧化物剥落并在高温下增强其强度。 优选地,管是通过挤出制造的,其中选择条件以提供具有凹槽和脊的粗糙表面,这进一步改善了氧化物层的粘附性。

    • A furnace for cracking of hydrocarbons, comprising one or several tubes through which the hydrocarbons flow during intensive heating and subsequent cracking. The starting material for the process can be e.g. naphtha or propane, mixed with a small amount of steam. When gases flow through the tube or tubes in the furnace, its temperature is increased up to about 850.degree. C. In order to achieve this, the temperature in the furnace compartment is 1100.degree.-1200.degree. C., and the temperature of the gases in the tubes in the furnace can then exceed 1100.degree. C. The tubes are made from an alloy comprising 15-30 weight % chromium, 3-10 weight % aluminum, the remainder of the composition being mainly iron. This alloy allows significant extension of the possible duration of operation without exchange of the tubes. A further improvement can be achieved by the formation on the inner walls of the tubes of a layer of aluminum oxide, obtained by oxidation of the tubes before the furnace is first used. The tubes are preferably seamless, and formed by extrusion of powder metallurgical billets.
    • 一种用于裂解烃的炉子,包括一个或几个管,烃在强化加热和随后的开裂期间通过该炉流动。 该方法的起始原料可以是例如。 石脑油或丙烷,与少量蒸汽混合。 当气体流过炉中的管或管时,其温度升高至约850℃。为达到此目的,炉室中的温度为1100-112℃,气体的温度 在炉中的管中可以超过1100℃。管由包含15-30重量%铬,3-10重量%铝的合金制成,其余组成主要为铁。 该合金允许显着延长操作的可能持续时间,而不需要更换管。 通过在炉子首次使用之前通过氧​​化氧化而在氧化铝层的管的内壁上形成进一步的改进。 管优选是无缝的,并且通过挤压粉末冶金坯形成。

    • An indexable insert for metal cutting having an upper surface, a bottom surface and side surfaces. At least a portion of the intersecting lines between the side surfaces and the upper surface generates a main cutting edge, a secondary cutting edge and a corner cutting edge. The corner portions of the upper side are provided with recesses. The corner cutting edge including at least two radiused edges having different radii. The first radiused edge, having a larger radius, being located adjacent to the main cutting edge and a second radiused edge, having a smaller radius, being located adjacent to the secondary cutting edge. Furthermore, the secondary cutting edge includes a radiused edge having a larger radius than the two aforementioned corner radiused edges and the recess includes a rear plane being so arranged that the chips hit a rear plane of the upper surface and break against the rear plane.
    • 一种用于金属切割的可转位刀片,具有上表面,底表面和侧表面。 侧表面和上表面之间的相交线的至少一部分产生主切削刃,次切削刃和角切削刃。 上侧的角部设有凹部。 角切削刃包括至少两个具有不同半径的圆角边缘。 具有较大半径的第一弧形边缘邻近主切割边缘定位,并且具有较小半径的第二弧形边缘邻近次切割边缘定位。 此外,二次切削刃包括具有比两个上述拐角圆角边缘更大的半径的圆弧边缘,并且凹部包括布置成使得切屑撞击上表面的后平面并且抵靠后平面的后平面。
