摘要： PURPOSE:To pass a metal strip through a conveying guide under non-contacting condition and to prevent breakage by adjusting blowing quantity of air at the time of detaching a rapid solidified metal strip with a cooling roll by blowing air and introducing into a pinch roll after guiding in the conveying guide. CONSTITUTION:Molten alloy is injected on the cooling roll 1 from a pouring nozzle 9 and the rapid solidified amorphous strip 2 is detached with an air knife 3 and this strip 2 is guided into the conveying guide 4. Then, at the time of flying in the conveying guide 4, in order to prevent this strip from colliding to inner wall of the guide, by advancing/retreating an adjusting plate 11 in the conveying guide 4, gas stream width from an air knife 3 is adjusted to control so that the strip 2 glides in the guide under non-contacting condition. Successively, the strip is introduced to the pinch roll 5' constituted with a brush under opening condition and a solid roll 5, and after passing the strip between the rolls, the cast strip 2 is caught with pressing down of the pinch roll 5'. The cast strip 2 in the conveying guide 4 is passed through without breakage under non-contacting condition with upper and lower faces and side face of the inner wall of the conveying guide and further, the tension is given to the strip with the pinch roll 5' to obtain the strip.

摘要： PURPOSE:To improve separation efficiencies and restrain clogging as well by reducing residual magnetism and to improve corrosion resistance by using a filter element in which amorphous metal is solidified in the form of bulk. CONSTITUTION:Thin pieces, flakes or powders of amorphous metal are formed into a bulky shape by application of warm drawing, not press etc. Filter elements in the form of bulk are put in a container 3 to form an agglomeration 2 of filter elements, which is magnetized by means of a magnetization coil 1 from the outside. A raw liquid to be treated is introduced from a fluid inlet 4 and passed through the filter elements in the container 3, during which impurities are removed by magnetic force. The treated liquid is discharged from a fluid outlet 5. When the removal rate of the filter elements has fallen due to clogging with impurities or the like, valves are changed over and magnetization is stopped so that liquids for back washing are caused to flow from a back wash inlet 7 to a back wash outlet 6 to effect back washing.

摘要： PURPOSE:To improve the yield of a molten metal and to reduce electric power consumption by positioning the rising part of a tapping path lower than the base of a storage chamber and providing an inclined flow route of a specific angle running toward a channel type induction heating part into a furnace. CONSTITUTION:The rising part 8 of the tapping path 3 in the furnace is positioned below the base 9 of the storage chamber 1. The rising part 8 and the channel type induction heater 10 are connected by a connecting route 11 having the base of >= 3 deg. angle of downward inclination from said part. The base 9 of the furnace is constructed to be built up by the above-mentioned method: therefore, the amt. of the remaining molten metal at the lower limit molten metal level of the molten metal 2 is correspondingly decreased. Since the downward inclined route 11 is installed, the convection of the molten metal is formed from the bottom of the storage chamber 1 to the heater 10, and the possibility of the solidification of the molten metal is eliminated. The amt. of the remaing molten metal to be discharge is, therefore, decreased, by which the yield is improved and the electric power consumption for holding the molten metal is reduced.
