Inventor: FUJITA TOSHIAKI
IPC: G01N29/04
Filed: 1987-12-26
Abstract: PURPOSE:To improve accuracy by projecting ultrasonic waves of a wide frequency band into a spheroidal graphite cast iron and measuring the upper limit value of the frequencies of the ultrasonic waves transmitted through the cast iron, then determining the fracture toughness of an object to be measured from the upper limit value of the frequencies. CONSTITUTION:The ultrasonic waves X of, for example, an about 0.5-10MHz frequency band are projected from an ultrasonic probe 2 into the spheroidal graphite cast iron which is the object 1 to be measured. Only the high frequency bands of the ultrasonic waves transmitted through and reflected by the object 1 to be measured scatter and attenuate according to the grain sizes of the graphite 3 and the distance between the graphite 3 particles and, therefore, the fracture toughness is determined as a relative value by measuring the upper limit value of the frequencies and the normal fracture toughness is obtd. by a suitable calibration curve. The fracture toughness is, therefore, measured with good accuracy by a non-destructive method.

Filed: 1988-12-28
Abstract: PURPOSE:To determine plural phases contg. the same element by using solvent mixtures composed of ethylene glycol and ethanol at different mixing ratios and determining extraction rates with each of all the metal elements contained in the composite oxide. CONSTITUTION:For example, 0.2g converter slag of <=200 mesh grain size is added to 60ml solvent mixture composed of the ethylene glycol EG and the ethanol and the mixture is stirred at 50rpm speed for 30 minutes at 50 deg.C by using a solvent extraction device to execute solvent extraction. The extraction is executed by changing the volume % of the EG from 0 up to 100vol.% by 5vol.% each. The respective extraction liquids are suction-filtered by using a regenerated cellulose filter of 0.2mum pore size and the Ca, Fe, Mn, Mg, and Si in the filtrate are determined by an atomic absorption photometry. Only the Ca is extracted at <=50vol.% mixing ratio. The other elements begins to be extracted at >=55vol.%. The Si is not extracted at all. Namely, only the unslag CaO in the composite oxide contg. the Ca is determined by setting the mixing ratio at 50vol.%.

IPC: G01N1/28
Filed: 1991-11-21
Abstract: PURPOSE:To prepare a sample which has an excellent solidified strength and is hardly decomposed by forming crushed slag particles to a prescribed shape after adding a water-soluble high polymer material as a binder to the particles. CONSTITUTION:After a slag sample taken from a blast furnace while the furnace is operated is cooled and crushed, a briquette-like sample 3 is prepared by pressing the crushed material 2 mount on a holder 1 after starch is mixed in the material 2.
