Henan Shuangzhi Machinery Equipment Co., Ltd. is a professional forging processing and production of forgings. Products can be produced according to the drawing, chemical composition, free forging, die forging, rough machining, heat treatment, finishing integration. Long-term cooperation with petroleum, chemical, mining, and other enterprises. Supporting the production of sprocket, gear, gear ring, ring, cylinder, shaft, cylinder, block, module, support seat, flange and other forging products. If you need custom forgings, you are welcome to contact us in time.
The quality inspection of die forgings includes appearance quality inspection and internal quality inspection, including numerous inspection items respectively. The first is the chemical composition inspection, usually based on the smelting before the furnace sampling analysis as. Especially for important or suspect die forgings, some chips can be cut from the forgings and chemical composition can be tested by chemical analysis or spectral analysis. Secondly, the size and shape of die forgings are checked. Visual inspection is a more common method to observe the surface of forgings with the naked eye whether there are folding, cracks, bruises, scars, surface burns and other defects. And the surface of die forgings hidden deep defects, often after heat treatment and cleaning for observation. And its dimension measurement inspection includes length, width and height dimensions; Parallelism and perpendicularity of the plane; The curvature of the axis; Ellipticity of inner and outer circles; Radius of fillet; The concentricity; The included Angle and the misshift, etc. When the die forgings are required to carry out the precise size inspection, in addition to the marking inspection and the special sample can be used, the inspection instrument controlled and analyzed by the computer can be used, or the optical comparator, optical projector can be used for the relevant size inspection, to ensure the accuracy of the inspection results. Surface flaw detection is also a part of the quality inspection of die forgings. The surface quality of membrane acid and base is determined by magnetic particle test and fluorescence test. In addition, there are ultrasonic inspection, low tissue inspection, microscopic inspection, residual stress inspection and so on, each link can not be ignored.
Raw melting material - aluminum scraps, cans, engine waste etc. Output capacity - 5-30 tons/h, customized Automation - Full automatic/ half automatic (based on output requirement and investment budget Ingot type - ADC12 (7.5kg/ 10kg / customized) 1. After cleaning the oil and grease of waste aluminum, manually put it into the furnace with a forklift; 2. Ignition for melting furnace .Heat up to 680C, and input appropriate proportion of alloy elements. Heat up to 800C, melt and stir evenly, then fetch samples to the spectrometer for testing. Every lot of production need to do testing . 3. Put A tool that attracts iron into the furnace by forklift, to suck away the iron in the aluminum water. 4. Put the slag agent into Alu liquid to remove the slag. After slag removed , put the slags into Aluminum ash separation machine , and let the aluminum water and ash separate. The proportion of slag agent and aluminum liquid is 1:500 5.Open the drain valve and the aluminum water flows automatically to the ingot production line After the ingot casting is completed, the ingot stacking robot will stack the ingots, which means the production is completed.
Cobalt-chromium-molybdenum alloy (CoCrMo) is a kind of cobalt-based alloy, and is also a kind of Stellite alloy. It is a cobalt-based alloy that is resistant to wear and corrosion. The first cobalt-based alloy was a cobalt-chromium binary alloy, which was later developed into a cobalt-chromium-tungsten ternary composition, and then later did the cobalt-chromium-molybdenum alloy develop. Cobalt-chromium-molybdenum alloy is a kind of alloy with cobalt as the main component, containing a considerable amount of chromium, molybdenum and a small amount of nickel, carbon and other alloying elements, and occasionally also containing iron.
