Abstract: The disclosure relates to the technical field of batteries, and in particular to a battery pack and an electrical device. The battery pack includes: a plurality of battery cells, any of which is provided with a fragile portion; and a spray pipeline, which is arranged on one side of the battery cell where the fragile portion is arranged. The spray pipeline is provided with an injection portion, and the injection portion abuts against the fragile portion. The fragile portion is impacted by a thermal runaway heat flow of the battery cell to form a pressure relief port, and the injection portion forms an injection port under the action of the thermal runaway heat flow, so that the cooling medium in the spray pipeline flows out from the injection port.

Abstract: Provided are an electromagnetic heating device, a noise suppression method, a heating control system, and a storage medium, which relate to the field of electromagnetic heating technologies. The noise suppression method includes: in response to determining that any two adjacent heating modules of the electromagnetic heating device operate successively, obtaining a start operating frequency of the last-started heating module of the two adjacent heating modules; and adjusting an operating frequency of the first-started heating module of the two adjacent heating modules based on the start operating frequency of the last-started heating module, to allow the two adjacent heating modules to operate synchronously at a same operating frequency when the last-started heating module starts operating.

Abstract: The present invention provides an in-situ method for synthesizing a Ni—W—WC composite coating, which includes the following steps: immersing a carbon steel substrate to be coated in an electroplating solution and electroplating, to obtain a Ni—W—C alloy coating on the surface of the carbon steel substrate; and then subjecting the alloy coating to high temperature heat treatment to obtain the Ni—W—WC composite coating. The electroplating solution comprises the following components: a nickel salt, a tungstate, citric acid, a citrate, a recarburizer, and a wetting agent. The present invention shows merits of simple operation, high current efficiency, simple electroplating process, and is clean and causes no pollution, thus meeting the requirements of environment protection.

Abstract: A blowing control method for maintaining a mushroom head of a bottom-blowing nozzle converter is disclosed. Considering the actual state of the mushroom head at the end of the bottom-blowing nozzle tip, the real-time molten steel overheating change during the blowing process, the process requirements of different stages of blowing conversion, and the macroscopic heat balance of the converter, the oxygen-carbon dioxide-lime powder blowing parameters of the inner tube of the bottom-blowing nozzle are dynamically adjusted during the converter smelting process of the bottom-blowing nozzle converter so as to control the cooling intensity, thus achieving precise control of the size of the mushroom head. The present invention maintains the basic stability of the size of the mushroom head at the end of the bottom-blowing nozzle tip, avoiding nozzle blockage caused by an oversized mushroom head and rapid erosion of the nozzle caused by an undersized mushroom head.

Abstract: There is provided a method of dynamic control for a bottom blowing O2—CO2—CaO converter steelmaking process. In the process, O2 is adopted as a top blowing gas, a mixed gas O2+CO2 is adopted as a bottom blowing carrier gas to inject lime powders into the converter from a bottom blowing tuyere. The ingredients of the molten steel in the converter steelmaking process are predicted based on the conservation of matter, in combination with the ingredient data of charged molten iron, the ingredient data of the converter gas in the converter blowing process, and working conditions of the bottom blowing device. The top blowing oxygen amount, the bottom blowing gas ratio and the flow rate of lime powder are dynamically adjusted stage by stage according to requirements for target ingredients at the end point of blowing.
