Low Phosphorus and Low Sulphur H13 Die Steel Melting by EF-LF(VD) Process;

The molecular mechanism of erythrocyte membrane damage in the low phosphorus hemoglobinuria cows;

The redox system of hypophosphorous acid and hydrogen peroxide was as the initiator to initiate the copolymerization of maleic anhydride and sodium p-styrene sulfonate so as to prepare a low phosphorus(below 4%) copolymer as a novel agent for the treatment of recycled cooling water.

Design and application of on-line low-phosphorus autoanalyzer based on intermittent measurement;

With sandy culture ,the effect of low-phosphorus stress on growth and phosphorus efficiency of the seedlings of the low-phosphorus-tolerant rice cultivars (Dalidao, Liantangzhao 3)and low-phosphorus-sensitive rice cultivars (Huzhanqi, Xinshanbaili) were carried out.

Each stage of low phosphorus steel production,such as the pretreatment of hot metal,converter steelmaking,secondary refining,especially the flux series for the dephosphorization in the secondary refining and the processes of steel dephosphorization is discussed in detail.

In order to produce ultra-low phosphorus steel, the deep dephosphorization experiment of steel containing phosphorus about 0.

It introduces the production control of low phosphorus and low carbon high silicon silicomanganese and the measures and crafts requirement of decreasing phosphorus and carbon.

003%C) and low-phosphorus steel, the metal yield can be increased by 1% and the oxygen consumption can be reduced by 8%.
