Nutrient capable of promoting health of crusts of aquatic crustacean, as well as preparation method and use method of nutrient

The invention discloses a nutrient capable of promoting the health of crusts of aquatic crustacean, as well as a preparation method and use method of the nutrient. The nutrient capable of promoting the health of crusts of aquatic crustacean comprises the following raw materials in percentage by weight: 5-25% of microelement nutrition sources and 75-95% of a synergist, wherein each kilogram of thenutrient capable of promoting the health of crusts of aquatic crustacean comprises the following microelement nutrition sources of copper, iron, zinc, manganese, iodine, cobalt, selenium, potassium, magnesium, sodium and calcium. The nutrient capable of promoting the health of crusts of aquatic crustacean integrates the functions of promoting exuviation, enriching the calcium, strengthening shells, preventing diseases and resisting stress, provides quality calcium sources and other mineral substances for the aquatic crustacean, and improves mineral substances of water bodies; the nutrient hasthe characteristics of being multiple in effects, safe, quick, high in absorption and utilization rate, convenient to use and the like; and the nutrient is directly put into the water bodies, the shells of the aquatic crustacean after exuviation can become hard quickly, the phenomenon that the shells are difficult to become hard is reduced, the nutrient has the efficacy of consolidating body resistance, strengthening bodies, defending virus invasion and promoting growth, and the survival rate of the aquatic crustacean is increased.

Coal powder additive for smelting of vanadium titano-magnetite and application of coal powder additive

The invention belongs to the technical field of metallurgical materials and particularly relates to a coal powder additive for smelting of vanadium titano-magnetite and application of the coal powder additive. The coal powder additive for smelting of the vanadium titano-magnetite is composed of 30-70 wt% of fluorite powder and 30-70 wt% of dedusting ash, wherein the sum of the weight percent of the fluorite powder and the weight percent of the dedusting ash is 100%; the content of CaF2 in the fluorite powder is greater than or equal to 80%; the content of Fe2O3 in the dedusting ash is greater than or equal to 80%; and the content of TFe in the dedusting ash is greater than or equal to 65%. The beneficial element iron in the dedusting ash is recovered, and recycling and reusing of secondary resources are promoted; oxygen potential of the high-iron dedusting ash in a blast furnace is improved, the coke ratio is lowered, slag system compositions of vanadium titano-magnetite furnace slag is improved by the fluorite powder, forming of Ti (C and N) is suppressed, the slag-iron separation effect is improved, and iron losses of the blast furnace are reduced; and the environment protection problem caused by dedusting ash processing through conventional methods is solved, and the environmental protection benefits are achieved.
