An iron redox flow battery system, comprising a redox electrode, a plating electrolyte tank, a plating electrode, a redox electrolyte tank with additional acid additives that may be introduced into the electrolytes in response to electrolyte pH. The acid additives may act to suppress undesired chemical reactions that create losses within the battery and may be added in response to sensor indications of these reactions.

The invention provides a method for producing grain-oriented silicon steel with single cold rolling, comprising: 1) smelting, refining and continuous casting to obtain a casting blank; 2) hot rolling; 3) normalization, i.e. normalizing annealing and cooling; 4) cold-rolling, i.e. single cold rolling at a cold rolling reduction rate of 75-92%; 5) decarburizing annealing at 780-880° C. for 80-350 s in a protective atmosphere having a due point of 40-80° C., wherein the total oxygen [O] in the surface of the decarburized sheet: 171 / t≦[O]≦313 / t (t represents the actual thickness of the steel sheet in mm), the amount of absorbed nitrogen: 2-10 ppm; 6) high temperature annealing, wherein the dew point of the protective atmosphere: 0-50° C., the temperature holding time at the first stage: 6-30 h, the amount of absorbed nitrogen during high-temperature annealing: 10-40 ppm; 7) hot-leveling annealing. The invention may control the primary recrystallization microstructure of steel sheet effectively by controlling the normalization process of hot rolled sheet to form sufficient favorable (Al, Si)N inclusions from nitrogen absorbed by slab during decarburizing annealing and low-temperature holding of high-temperature annealing, facilitating the generation of stable, perfect secondary recrystallization microstructure of the final products. In addition, the invention avoids the impact of nitridation using ammonia on the underlying layer in prior art, and thus the formation of a good glass film underlying layer is favored.

The invention discloses a rotatable classification garbage can. The rotatable classification garbage can comprises a first supporting column and a second supporting column, wherein T-shaped rotating rods can be fixedly connected to the inner side of the first supporting column and the inner side of the second supporting column correspondingly, one side of each T-shaped rotating rod is movably sleeved with a cavity block, one sides of the cavity blocks are fixedly connected with shells, a top cover is fixedly connected to the tops of the first supporting column and the second supporting column,and a first guide plate is fixedly connected to the inner sides of the first supporting column and the second supporting column. Through the designed T-shaped rotating rods and the designed cavity blocks, the shells can be turned over, people can throw garbage conveniently, meanwhile, through arrangement of a sleeve rod, a guide rod, a first reset spring, a first limiting plate and a clamping block, the shells can be automatically reset after rotating and moving, therefore the practicability of the device is improved, and the problems that an existing device is low in garbage throwing efficiency, and some garbage can fall out of a garbage can are solved.
