摘要： PURPOSE:To measure the surface temperature of a moving cast piece continuously by fastening a metal piece provided successively at the tip of a temperature measuring means such as seath type thermocouple or the like on the surface of a cast piece with a metal stud of a desired shape loosely fitted into the metal piece. CONSTITUTION:The tip of a temperature measuring means 1 is attached integral on the side of a disc-shaped metal piece 2 made of a highly heat conductive material by imbedding, welding or the like. A through hole 3 is provided almost in the center of the metal piece while both upper and lower surfaces are made a roughly smooth plane. The metal stud 5 allows the metal piece to be brought into tight contact with the top surface of a cast piece so that the temperature of the top surface thereof can be measured accurately. This eliminates the danger of damage to the temperature measuring means or diterioration in the function, as compared with the convensional type.

摘要： PURPOSE:To easily produce a metallic mold by using simple compacting frame, by utilizing a method squeezing liquid in slurry of powder in the compacting frame, squeezing the liquid from linear slit in the compacting frame having the specific width and sintering the obtd. green compact. CONSTITUTION:The slurry 7 formed by adding and mixing metal powder for sintering, organic binder and water or organic solvent is prepared. Further, at the time of using (d) for average particle size of the above metal powder, the compacting frame 1 having the linear slit 3 satisfying the inequality to the slit width S is prepared. Then, inversion model 5 having transfer face of similar shape as the product forming larger than the product shape under consideration of shrinkage percentage of the product and shrinkage percentage at the sintering operation is inserted into the frame 1 and the slurry 7 is poured into the frame 1 and compressed by pushing-down of a plunger 6. By this method, the liquid in the slurry 7 is discharged from the slit 3 to obtain the green metal powder compact. This is sintered and a sintered metallic mold element having larger than the finish product by the shrinkage thereof at the time of forming the finished product, is obtd. and by this metallic mold element, the metallic mold having cavity with shape similar to that of the product shape in the interior thereof is made.

摘要： PURPOSE:To enable smooth casting of a kind of steel having high high-temp. strength without trouble in a method for forming a lubricating layer contg. WS2 and MoS2 on the inside surface of a casting mold by forming a hard plasma melt sprayed layer in place of a plating layer of Ni, etc. to be preliminarily formed on the inside surface of the casting mold. CONSTITUTION:A plasma melt-sprayed layer 2 of carbide, oxide, etc. is formed only in the specific range on the outlet side of a casting mold 1 to prevent generation of scratch flaws. A lubricating layer 3 contg. WS2 or MoS2 for relieving the friction resistance with a cast billet is formed over the entire inside circumferential surface of the mold 1 including the layer 2. If a steel such as stainless steel having high high-temp. strength is cast by using the mold 1 subjected to the inside surface treatment in the above-mentioned way, the cast billet having a good surface characteristic is produced stably for a long period of time.

摘要： PURPOSE:To rabble slab by waveform shifting magnetic fields and improve its internal quality by moving plural mutually adjoining electromagnetic induction coils while letting them alternately make contact with and space from the side faces of the slab. CONSTITUTION:Plural electromagnetic induction coils 7 opposedly disposed in the width direction of the slab 3 right under a mold 4 are pressure contacted with and spaced from the slab 3 alternately at a fixed period together with slab guide devices 5. Arrangement is so made that the adjoining electromagnetic induction coils 7 are also alternately energized by this. At the same time, the coils 7 are the electromagnetic induction coils having the windings of linear motor primary coil type which generate shifting electromagnetic fields in the lengthwise direction of the slab guide devices 5. As a result of this, the shifting magnetic fields being applied to the slab 3 of thin frozen crust 3a and whose inside is almost unsolidified are applied to the same region alternately in waveform for a fixed time, whereby the slab 3 is rabbled by the more intricate patterns as compared to conventional methods.

摘要： PURPOSE:To improve yield with the decrease in loss by mending and to produce a blank material for forging having good quality by specifying the step between a connecting ring and a casting mold and performing casting. CONSTITUTION:A billet is drawn after the length (l) of the stroke for intermittent drawing of the billet is set at the length of the blank material for forging to be obtd. within a 50-500mm. range. The step (d) between a connecting ceramic ring 4A and a casting mold 2A is further increased to d>3.4 (60/N) (where N: the drawing cycle of a time/minute unit) in order to grow deeply a cold shut 7 in the direction perpendicular to the surface of a billet 6A. The billet is cut in the position of the cold shut 7A which is the discontinuous solidified part of the billet surface after the billet 6A is drawn in the above-mentioned way. The cut billet is used as a blank material for forging.
