Abstract: A process for the production of grain-oriented electric quality sheet by melting a silicon steel and casting the melt continuously into a strand having a thickness of 25-100 mm. During solidification the strand is cooled to a temperature above 700° C. and divided into thin slabs. The thin slabs then pass through an equalization furnace standing in line where they are reheated to a temperature ≦1170° C. and continuously rolled in a multi-stand hot rolling mill to give hot strip having a thickness of ≦3.0 mm. The first shaping pass is performed at a temperature in the rolling stock up to 1150° C. The reduction in thickness is at least 20%. The hot strip is cold rolled in one or more stages with recrystallizing intermediate annealing to a final thickness in the range of 0.15-0.50 mm. The cold strip is then annealed with recrystallization and decarburization, furnished with a predominantly MgO-containing annealing separator and given a final annealing for imprinting a Goss texture.

Abstract: A process for preparing alkali metal salts of L-ascorbic acid comprising the following steps: a) esterifying 2-keto-L-gulonic acid or diacetone-2-keto-L-gulonic acid with a C1-C10-alkohol in the presence of an acid catalyst, b) rearranging the resultant 2-keto-L-gulonic acid C1-C10-alkyl ester in the presence of an alkali metal C1-C10-alkoxide, comprises carrying out each of the process steps a) and b) continuously.

Abstract: The invention relates to a process for the preparation of L-ascorbic acid, which comprises lactonizing a melt of alkyl 2-keto-L-gulonate under acidic conditions.

Abstract: A process for producing a grain-oriented magnetic steel sheet in which a slab, made from a steel containing (in mass %) more than 0.005 to 0.10% C, 2.5 to 4.5% Si, 0.03 to 0.15% Mn, more than 0.01 to 0.05% S, 0.01 to 0.035% Al, 0.0045 to 0.012% N, 0.02 to 0.3% Cu, the remainder being Fe, including unavoidable impurities, is heated through and hot rolled to a final thickness between 1.5 and 7.0 mm. The hot strip is annealed and immediately cooled and cold rolled in one or several cold-rolling steps to the final thickness of the cold strip. The cold strip is subjected to a recrystallizing annealing process in a humid atmosphere containing hydrogen and nitrogen, with synchronous decarburization. A non-stick layer, essentially containing MgO, is applied to the surface of the decarburized cold strip which is then subjected to final annealing. The cold strip is then rolled into coils.

Abstract: A process for preparing salts of ascorbyl 2-phosphoric esters of the formula I, ##STR1## where the variables have the following meanings: M is sodium, potassium, magnesium, aluminum; ##STR2## k.sym. is the valence and m=equivalents, where the product of k.multidot.m can be from 3 to 5,comprisesa) dissolving calcium L-ascorbate-2-phosphate in an aqueous solution of ascorbyl 2-phosphoric esters at a pH of from 0.5 to 4,b) removing the calcium ions from the resulting solution,c) adjusting the pH of the solution which remains to from 7 to 11 by means of sodium, potassium, magnesium or aluminum salts andd) isolating the salts of the ascorbyl 2-phosphoric ester of the formula I.

Abstract: The invention relates to a structure for a firing table to accept ceramic items to be fired.

Abstract: A process for the production of grain oriented magnetic steel sheets having improved remagnetization losses consisting essentially of (in % by weight) more than 0.005% to 0.10% C, 2.5 to 6.5% Si, 0.03 to 0.15% Mn, 0.010 to 0.050% S, 0.010 to 0.035% Al, 0.0045 to 0.0120% N, and 0.020 to 0.300% Cu, and up to 0.15% Sn, the balance being iron and inevitable impurities. The process includes continuous casting or strip casting slabs with the above composition.
