The invention belongs to the field of heavy metal wastewater treatment, and specifically refers to a self-resetting type interventional and passive operation metal recovery machine for copper sewage treatment, which is integrated with an interventional all-round odor isolation and vibration power source, self-resetting maintenance-free dynamic and static state The setting of switching unit, element-eliminating passive stirring and self-conveying integrated unit realizes the integration of interventional all-round odor isolation and vibration power source, self-resetting maintenance-free dynamic and static state switching, element-eliminating passive stirring and self-conveying integration, etc. multiple effects.

The invention relates to a reductant NFA used for deep deoxidization in the copper industry and belongs to the technical field of non-ferrous metallurgy. The reductant NFA is obtained by removing impurities of anthracite or petroleum coke and pitch coke, subjecting oxidized ore of Al, Si, Ca and Mg to strong reduction to obtain elementary substances or alloys, separately smashing and sieving the abovementioned two raw materials to obtain particles having a size of 0.1-5 mm, and mixing the two kinds of materials according to the requirements of the refining process to obtain the reductant NFA. The reductant NFA can also be obtained by directly mixing the two raw materials, subjecting the mixture to strong reduction at high temperature, smashing and sieving. In a reduction stage in the later period of fire refining of crude copper, single adoption of the reductant NFA or combination of the reductant NFA with a traditional reductant can achieve the objective of deep deoxidization of fire-refined copper and can make the resident oxygen lower than 30-1500 ppm. The reductant NFA is suitable for the cooper smelting industry and the copper processing industry.

The invention belongs to the field of nonferrous metal processing, and in particular relates to a high-hardness zinc-copper-aluminum alloy. The invention uses Al-50Cu master alloy, industrial pure copper, industrial pure aluminum and industrial pure zinc as raw materials, adopts the method of smelting, casting and natural cooling to prepare high-hardness wear-resistant zinc-copper-aluminum alloy, and the composition of the alloy is 30-38%. Zn, 30-38% Cu and 30-38% Al, the unavoidable impurity content is less than 0.8%, the preferred alloy composition is copper, aluminum and zinc metal components with equal mass percentages, and its hardness and wear resistance are the best. The zinc-copper-aluminum alloy with high hardness obtained by the invention can be applied to industrial fields such as machinery and mines.

The invention discloses a copper bar cutting machine for the copper industry. The copper bar cutting machine comprises a box body, wherein a movable block is connected to the top of the inner wall ofthe box body in a sliding mode, arc-shaped blocks are fixedly connected to the top of the movable block and the other side of the top of the box body respectively, an elastic telescopic rod is fixedlyconnected to the bottoms of the inner walls of the arc-shaped blocks, a cushion block is fixedly connected to the top of the elastic telescopic rod, and first arc-shaped clamping blocks are fixedly connected to one side of the inner walls of the arc-shaped blocks by virtue of support blocks. The copper bar cutting machine relates to the technical field of copper bar cutting equipment. According to the copper bar cutting machine for the copper industry, friction blocks and antiskid blocks are arranged, so that the friction between fixtures and copper bars is increased, the copper bars are preferably prevented from moving during cutting, the copper bar cutting effect is greatly increased, the distance between the fixtures can be preferably adjusted through the movement of the movable block,a clamping block can be preferably clamped with a bulged block through the movement of the clamping block, the stable fixture position adjustment is guaranteed, and the practicability of the cuttingmachine is greatly increased.
