Granted: 1998-05-10
Abstract: FIELD: steelmaking. SUBSTANCE: invention relates to out-of-furnace treatment of smelted steel before continuous casting. Into the ladle with steel, aluminum wire is fed with velocity 5-10 m/s and total uptake 0.4 to 4.0 kg per 1 t steel. When 5-25% of the total aluminum uptake is consumed, steel begins to be blown by oxygen with oxygen uptake varying from its maximum value equal to 0.15-0.25 cu.m/min t in the beginning of blowing to its minimum value 0.06-0.08 cu.m/min t at the end of blowing. Rest of aluminum is added with current uptake proportional to varying current oxygen uptake according to dependence q= (2.5-12)Q, where q is current aluminum uptake, kg/min t, Q current oxygen uptake, cu.m/min t, and 2.5-12 empirical coefficient of proportionality characterizing physico-chemical regularities in observing necessary stoichiometric ratio of current uptake values for aluminum and oxygen, kg/cu.m. Oxygen-blowing lance may be immersed under steel level to the value equal to 0.2-0.8 height of steel column in the ladle.

Filed: 1997-07-30
Granted: 1998-11-10
Abstract: FIELD: agriculture. SUBSTANCE: claimed method comprises neutralizing reaction mixture during sorbose acetonation with alkaline agent and subsequently demineralizing said mixture. Alkaline agent includes aqueous potassium hydroxide solution and demineralization is carried out quantitatively by direct crystallization of potassium sulfide resulting from aqueous acetone solution. Differences in the nature of sodium and potassium cations make potassium sulfate insoluble in aqueous acetone medium and leads to complete deminiralization of reaction mixture. This enables one to improve quality of the desired product such as diacetone-L-sorbose, to exclude additional stage of processing aqueous solution of mineral salts, removing water and separating them from monoacetone-L-sorbose solution. Use of potassium hydroxide for neutralization of reaction mixture in placed of potassium hydroxide solution makes it possible to prepare as one of products commercial potassium sulfate which is more preferable ecologically since potassium sulfate is in great demand as potassium fertilizer in agriculture.

Granted: 2000-05-27
Abstract: FIELD: explosives. SUBSTANCE: invention relates to technology of preparing blended explosives and, more particularly, to oxidant for simple or water- containing explosives to be applied in mining and construction areas. Alkali and/or alkali-earth metal aluminosilicates (nepheline, leucite, anorthite, feldspar) are treated with nitric acid to form aluminum nitrate and free nitric acid, which are brought into interaction with ammonia to give aluminum hydroxide and solution containing ammonium, potassium, sodium, and calcium nitrates. 75-95% of aluminum hydroxide is separated and the rest of it is used as modification additive for explosive oxidant. Achieved result consists in obtaining high-efficiency complex oxidant fit to prepare miscellaneous simple and water-containing explosives. Modifying oxidant with aluminum hydroxide confers oil- retaining and thickening capacity, which enables preparing water- resistant explosives with stable blast characteristics. Inexpensiveness of starting material, completeness of processing thereof, and needlessness of complete evaporation of solution when water-containing explosives are prepared assure considerable reduction in cost of oxidant. Engineering economy study has shown that it is by 20 to 40% lower as compared to cost of existing oxidants. EFFECT: increased economical efficiency of process. 6 cl, 1 tbl, 13 ex
