Granted: 1997-10-23
Abstract: The invention concerns a method of producing hot-rolled steel strip from continuously cast semi-finished steel in operating steps which follow one another directly. According to the invention, when the liquid steel has been transformed into the semi-finished steel in a stationary process, the semi-finished steel is introduced directly into a continuous hot-rolling mill without previously being separated from the continuous casting machine. By applying specific parameters, continuous steel strip of any thickness is then produced directly using the primary heat at the final rolling temperatures conventional in industrial processes.

Title: Plasma-activated electron beam vapour deposition
Inventor: SCHEFFEL BERT
IPC: C23C14/30
Filed: 1997-06-13
Granted: 1998-09-03
Abstract: Known methods of plasma-activated evaporation are essentially based on the introduction of a noble gas between the evaporator and the substrate being coated, the electric discharge being maintained in said noble gas. The disadvantage of this process is that noble gas particles are then integrated into the layer. This has a detrimental effect on the properties of said layer. According to the invention, the evaporant or its crucible serves as an anode. A rod-shaped electrode which serves as a cathode is moved into an area where the vapour is denser and this part of the cathode is heated. An arc discharge is ignited and maintained in the vapour. The inventive method is used to increase the adherence of the layer as well as its structure, and is particularly suitable for coating strip steel.

IPC: A23K10/32
Filed: 1992-12-14
Granted: 1995-04-10
Abstract: FIELD: agriculture and silviculture. SUBSTANCE: method involves grinding the mixed branch mass of coniferous trees and its vapor-liquid extraction with steaming, lamination and extraction of resinous, fat-containing and vitamin-containing concentrates and cellulose-containing residue, mixing and heat treatment of the newly-formed mixture followed by drying or granulating. The mixture of chopped branches of coniferous trees is ground in two stages and the resulting wood mass is laid into swaths. The low-temperature steam-liquid extraction is carried out by applying the vapors of gasoline and water at a temperature not over 80-95 C and separating the vitamin-containing concentrate. The subsequent high-temperature extraction produces the cellulose-containing residue of the coniferous green mass. The resulting residue is delivered into a fodder steaming plant where it is heat-treated and mixed with enzyme-yeast mixture. A a temperature of 50-70 C the previously produced vitamin-containing concentrate is subjected to surface pulverization with mixing. The method also involves certain technological method for preparing individual products or treating them at individual stages. This ensures complex closed-cycle processing of greenery and wood, reduces consumption of feedstock and energy carriers and results in a maximum preservation of nutrient and vitamin compounds. The prepared product contains about 0.35-0.38 fodder units, has a high biological activity and features good assimilation capacity. EFFECT: higher efficiency. 7 cl
