MOLD PIN SAMPLER FOR MEASURING DEGREE OF CLEARNESS OF MOLTEN STEEL FOR ENSURING MOLTEN STEEL SAMPLE HAVING GOOD QUALITY BY INSTALLING SUCTION UNIT

摘要

Purpose: a mold pin sample is configured to ensure that a molten steel sample for the clear molten steel of degree of measurement, has by one aspirator of installation high-quality. Construction: a mold pin sample, for the clear molten steel of degree of measurement one, including a quartz ampoule (10) and an aspirator (12). The part that quartz ampoule (10) comes to an end through a paper cap (11) covering. Aspirator (12) is connected to the other end part of quartz ampoule (10) and generates an inhalation power, has the scheduled intensity in quartz ampoule (10). Inhalation power hydraulic is generated by one. Aspirator (12) includes adapter tube (13), the cylinder (18) for being connected to the aspirator (12) of other end part of quartz ampoule (10), the piston (14) for being connected to the other end part of adapter tube (13), being inserted into cylinder (18), and a spring (15), it is provided in such mode that a pulling force is employed in inhalation power opposite at one.
