The composite phase change material according to the invention has a good stability and a thermal conductivity, a small corrosivity, a high phase transition enthalpy of 150-350 J/g, and a morphological stability during phase change. Moreover, addition of high thermal conductivity material and composite flame retardant ensures good thermal conductivity and excellent flame retardant effect of the phase change material.

Abstract: A tool discharges one battery pack and a charger simultaneously charges another battery pack to provide for continuous and circular operation of the tool. The ratio of the discharging time to the charging time is approximately 25:35.

Abstract: A method is provided for monitoring and controlling the process consistency of an arc welding process. The weld voltage signal is monitored and analyzed to determine the occurrence of the detachment of a weld droplet. The weld droplet detachment is determined via statistical techniques as having occurred at a normal interval following a prior detachment indicating consistent weld process or as a sporadic detachment having occurred at an irregular interval with respect to the prior detachment and indicating inconsistent weld process. The weld process is adjusted by controlling the weld process variables to maximize the predominance of droplet detachment at normal intervals and minimize the occurrence of the sporadic detachments.

Abstract: This invention belongs to ferrous metallurgy field, and in particular relates to a lime-based additive for steel smelting which is used in the electric furnace refining and steel casting process for carbureting and deoxidation and the preparation method thereof. The lime-based additive for steel smelting comprises lime-based material and carbonaceous material, wherein the content of the lime-based material is 40-80 wt % relative to the total amount of the additive, and the remaining is the carbonaceous material; the lime-based material is a passivated CaO powder with a low flowability, or the mixture of the passivated CaO powder and CaCO3 powder, and the carbonaceous material is at least one of the coke, graphite, semi-coke powder and coal with carbon content not less than 85 wt %. When the additive has a shape of pellet, and it further comprises 1-5 wt % of agglomerant which has a microstructure of strip, streak or dendritic, and is at least one of MgO, Al2O3, and CaCO3.
