Patent PT-90543-B (PT)
Inventor: BOBADILLA MANUEL
IPC: B22D11/12
Filed: 1989-05-12
Abstract: The method according to the invention is characterised in that an intense cooling of the product in the process of being continuously cast is carried out when the latter is, at its core, in the pasty solidification phase (8), as a result of which the differential thermal contraction between the pasty core and the outer shell which is already completely solidified produces a squeezing effect of the core by the shell (9). To this end, means for cooling the product are arranged on the casting machine in the region of the terminal portion of the metallurgical length. 
<??>The invention makes it possible to reduce, and even prevent the formation of internal cracks during the cooling of the cast product, which would lead to the presence of segregated areas in the axial region. It is applied advantageously to the casting of steels which are well known to be difficult to cast by continuous casting, such as steels with a wide solidification range, the carbon content of which is from 0.25 to 1.5%.

Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.

Title: Arrangement for mineral concentration
Inventor: SANDSTROEM GUSTAV
IPC: B03B5/04
Filed: 1987-12-18
Abstract: The invention concerns an arrangement for the concentration of minerals using air or water, alternatively with air and water simultaneously. The invention achieves this by passing compressed air, or water under high pressure, through 17 from the side to the concentration hearth 1 in transport direction 19 and towards 3,4 and 2. The invention is based entirely on the specific weight of the material to be concentrated, and therefore does not depend on whether the mineral is or is not magnetic. Both types of ore can be treated in the same way. The invention also solves the problem of concentrating minerals in their dry state, which must be of great advantage in desert regions. The invention also shows that concentration can be carried out simply through adjustment towards 27 without rocking during controlled drop of the mineral and with air from 17. The invention can therefore effectively be used for mineral dressing. <IMAGE>
