Abstract
The utility model discloses a kind of residual brick device for measuring length of disc type porous core, including holding rod, one end of holding rod is connected through a screw thread a sleeve pipe, vertical affixed the disk in sleeve pipe one end, a diameter of 170mm of disk.The utility model can be more accurately known that by scientific and reasonable means at present the use of the residual brick length of porous core of ladle is how many, be still continuing with determining that the ladle should change porous core.
Description
Technical field
It the utility model is related to a kind of residual brick device for measuring length of disc type porous core.
Background technology
Ladle ventilating core brick is that a kind of outer wrap the thick box hats of 2mm, and inside contains fine and close gaseous core, cast by pink fused alumina,
The conical objects of air bag are arranged at bottom, and its effect is to convey argon gas to molten steel while molten steel high temperature erosion is resisted, and it is installed
In ladle bottom, argon gas by it, the argon gas stirring to molten steel can be completed in converter tapping or refining furnace smelting process, with
This smelts purpose to realize molten steel uniform temperature, composition and float to be mingled with etc..The new brick length of ladle ventilating core used at present
Spend for 450mm, with the use of porous core, ventilation face causes porous core length constantly to shorten constantly by molten steel, so
It can be changed using to guideline lives, if range estimation is inaccurate, the residual brick of porous core is corroded seriously, and the position may be caused to wear
Steel, serious accident is caused, but due to manually wrapping the operating method of bottom porous core by observing to the residual brick length of porous core
Range estimation often error is larger, the residual brick of the porous core under changing tends not to reach the target 150mm of expected safe handling.
The content of the invention
The purpose of this utility model is to provide a kind of disc type porous core residual brick device for measuring length, can closed by science
The means of reason be more accurately known that at present the use of the residual brick length of porous core of ladle is how many, to determine that the ladle should be more
Porous core is changed still to be continuing with.
The purpose of this utility model is achieved in that a kind of residual brick device for measuring length of disc type porous core, including grips
Bar, one end of holding rod are connected through a screw thread a sleeve pipe, vertical affixed the disk in sleeve pipe one end, disk it is a diameter of
170mm。
Measuring appliance is stretched into ladle, by disk by the utility model in use, when steel ladle pouring is completed to lie on support
The ventilative core section of alignment, judgment mode：When observation finds that ventilative core section is less than disk and all covered by disk, it can determine whether
The residual brick of gaseous core can be continuing with more than 150mm, porous core, when ventilative core section is not covered by disk, during edge exposure, be said
The bright residual brick length of porous core is less than 150mm, should stop using immediately, by this measuring appliance, can intuitively determine to breathe freely
Core can be continuing with or need to change, and ensure that the safe handling of ladle.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model.
Embodiment
A kind of residual brick device for measuring length of disc type porous core, as shown in figure 1, including holding rod 4, one end of holding rod passes through
It is threadedly coupled a sleeve pipe, vertical affixed the disk 3 in sleeve pipe one end, a diameter of 170mm of disk 3.When ladle 1 is poured into a mould
When completion is lain on support, measuring appliance is stretched into ladle, disk is directed at the section of porous core 2, judgment mode：Observation finds saturating
When gaseous core section is less than disk 3 and all covered by disk 3, the residual brick of porous core is can determine whether in more than 150mm, and porous core can be after
It is continuous to use, when ventilative core section is not covered by disk 3, during edge exposure, illustrate that the residual brick length of porous core is less than 150mm, answer
Stop using immediately.
