Description
Technical field
The utility model relates to the conticaster of field of metallurgy, more particularly, relates to a kind of mould liquid level calibration tool.
Background technology
Conticaster is a kind of liquid molten steel directly to be watered into the machine of solid-state steel billet, and capital equipment partly is comprised of steel ladle rotary table, tundish, plug rod mechanism, crystallizer, bobbing machine, secondary spraying device, withdrawal straightening machine, dummy bar, cutting equipment, knockout mechanism, water-cooled live-roller etc.
Conticaster crystallizer liquid steel level automatically control is the key link that realizes the continuous casting installation for casting automation, measure in the tundish or the liquid level of molten steel in mold, by voltage or the current analog amount of liquid level regulating system output with the liquid level linear change, automatically control the process of casting speed or control stopper, remain on predetermined height with making the molten steel in mold surface-stable, reach the purpose that improves the conticaster operating rate.
Crystallizer liquid steel level automatically control mainly contains magnetic float glass process, thermocouple method, isotope method and infra-red method.Wherein isotope method is a kind of relatively tradition and method commonly used, this method makes the radioactive substances such as apparatus Co 60 or Ce 137 as penetrating the side that the source is arranged in crystallizer, other side at crystallizer arranges ray detector, the γ particle is sent in the source of penetrating, penetrate the materials such as crystallizer, molten steel, accepted by ray detector, ray detector converts the γ particle that receives to photosignal, thereby detects the liquid level of molten steel.
Use aborning and penetrate before source and the ray detector, we need to carry out the liquid level staking-out work, its objective is to set empty liquid level and full liquid level, are used as controlling two limiting values of molten steel position with this, can detect the attenuation of radioactive source simultaneously.The liquid level staking-out work need to adopt the liquid level calibration tool to realize, concrete is to stretch to soon a consistent steel simulation in shape syncrystallization type chamber in the crystallizer internal cavity, then demarcate in predefined full liquid level and empty liquid level position, if the detection linearity, then between the position of empty liquid level and full liquid level, each certain distance carries out reading out data and position, then by calculating to analyze the linearity in the source of penetrating.
Present employed liquid level calibration tool generally is comprised of simulated block, gripper shoe, screw rod, turning handle and ruler, during use, with gripper shoe as support, rotary handle, progressively be sent to simulated block in the crystallizer internal cavity by screw drive, then use the position of ruler measure analog piece, demarcate (numerical value reads) in predefined position.Adopt this instrument and method, several shortcomings once arranged:
One, simulated block adopt iron and steel to make, and weight is larger, and dish expends muscle power when turning.
Its two, simulated block stretches into crystallizer for rotation, and is long-pending larger with the crystallizer relative contact, abrades easily damage crystallizer inwall.
Its three, ruler enters crystallizer internal cavity and measures, and is subject to radiation injury, for this reason in operating process, puts into ruler and just need to close She Yuan before measuring whenever detection, causes the whole operating time long.
