摘要： Disclosed are a Nb microalloyed high strength high hole expansion steel and a production method therefor. The chemical ingredients of the steel in percentages by weight are as follows: 0.01-0.05% of C, 0.2-0.6% of Si, 0.8-1.5% of Mn, ≤0.02% of P, ≤0.005% of S, ≤0.008% of N, 250, total oxygen [O]T is 0.007-0.020%, and the balance is Fe and inevitable impurities. In the present invention, microalloy elements such as Nb are selectively added, and the basicity of slag, the type and melting point of the inclusion in steel, the content of free oxygen in molten steel, and the content of acid-soluble aluminum Als during the smelting process are controlled, and then, a strip is cast by means of twin-roll thin strip continuous casting, and the strip directly enters a lower closed chamber in a non-oxidizing atmosphere and enters an online rolling mill for hot rolling in closed conditions, and after rolling, the strip steel is cooled by air atomization cooling, and finally, the produced steel coil can be used directly as a hot rolled plate or can be used after acid pickling and leveling.

摘要： For making battery electrodes, a composite strip of a cast ribbon of an electrically conductive metal attached to and extending along an edge of a web of electrically conductive carbon fiber material, also called a carbon felt in some examples, with a plurality of spaced apart notches cast in the ribbon and opening to an edge of the ribbon spaced from the carbon fiber material. A rotatable drum with a mold cavity and a confronting casting shoe for supplying molten metal, such as liquid lead, to the cavity may be used in a casting machine to continuous cast the composite strip.

摘要： A roll line unit for a continuous casting apparatus includes a roll mantle having two ends and a non-rotatable shaft including a coolant line. The roll mantle is rotatably mounted on the non-rotatable shaft by means of a first bearing located in a first end region of the roll mantle and a second bearing located in a second end region of the roll mantle. The roll mantle includes at least one coolant channel having at least one fluid inlet that is arranged to be in fluid communication with the coolant line. The roll line unit includes two outer seals located on an axially outward side of each of the first and second bearings, whereby the outer seals and the first and second bearings are located axially inwards of the ends of the roll mantle.
