Description
Technical Field
The utility model relates to a measure slide caliper rule of tundish mouth of a river centering nature belongs to metallurgical steelmaking technical field.
Background
At present, continuous casting production in a steel plant generally adopts a multi-machine multi-flow production mode, particularly a continuous casting machine with a small square billet section is commonly a 5-machine 5-flow continuous casting machine and a 7-machine 7-flow continuous casting machine, and the situation that a tundish nozzle is not completely centered when being inserted into a crystallizer inevitably occurs in the actual large production process. The misalignment of the nozzle can bring a series of hazards, particularly in the production activity of special steel, the flow field and the temperature field in a crystallizer can be changed to a certain extent, small square billet subcutaneous inclusions and subcutaneous cracks are easy to generate, the quality of the billet is seriously influenced, and various defects are caused by subsequent rolling, so the centering performance of the tundish nozzle during pouring of the multi-strand casting machine is an important index for measuring the quality of the continuous casting billet, however, due to poor field actual environment and narrow space, the centering condition of the tundish nozzle during actual production is a difficult matter, a common steel mill adopts a steel ruler or a tape measure for measurement, the measurement error is large, and the measurement process consumes time and power.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a slide caliper rule of measuring tundish nozzle to neutrality is provided to above-mentioned prior art, not only simple structure, the simple operation practices thrift measuring time, improves the measuring accuracy moreover.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a measure middle package mouth of a river slide caliper rule to neutrality, is including the blade, the fixed claw of measuring, the movable claw of measuring and the slip vernier that are equipped with the scale, the fixed blade initiating terminal of locating of fixed claw of measuring, the activity of slip vernier sets up on the blade and can slide along the blade, the movable claw of measuring is fixed to be located on the slip vernier.
And a level gauge is arranged on the sliding vernier and is parallel to the ruler body.
The sliding vernier is provided with a movable grid, the ruler body is provided with a fixed grid, the sliding of the sliding vernier enables the capacitance between the movable grid and the fixed grid to change according to a certain rule along with the relative displacement of the movable grid and the fixed grid, and the sliding vernier is provided with a display device for displaying the distance between the fixed measuring claw and the movable measuring claw.
The fixed measuring claw and the ruler body are integrated or fixedly connected in a welding mode.
The section of the fixed measuring claw is shaped into a semicircular arc or a one-third circular arc.
Compared with the prior art, the utility model has the advantages of: a caliper for measuring the centering performance of a tundish nozzle is characterized in that an operator operates a sliding vernier to open a measuring claw of the caliper, the fixed measuring claw clamps the outer diameter of the tundish nozzle, a movable measuring claw clamps the edge of a crystallizer, observes a bubble level meter and adjusts a caliper body to enable the caliper to be in a horizontal state, reads the numerical value of a liquid crystal display screen on the sliding vernier, and effectively improves the accuracy and convenience of the centering performance measurement of the tundish nozzle; when the liquid crystal display screen is powered off, data can be read through the scales on the ruler body, the operation is simple, and the measuring time is saved.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the caliper for measuring the alignment of the tundish nozzle in this embodiment includes a ruler body 2 having scales 7, a fixed measuring claw 1, a movable measuring claw 6, and a sliding cursor 3, the fixed measuring claw 1 is fixed at the starting end of the ruler body, the sliding cursor 3 is sleeved on the ruler body 2, the movable measuring claw 6 is fixed at the bottom of the sliding cursor 3, and the sliding cursor 3 drives the movable measuring claw 6 to slide relative to the ruler body 2. Be equipped with the bubble spirit level 4 parallel with blade 2 on the slip vernier 3 for whether the blade keeps the horizontality when the calibration is measured, in view of measuring environment comparatively special and complicated, produce the measurement inaccuracy that blade 2 slopes to lead to easily when actual measurement, use the slide caliper rule slope when spirit level 4 can effectively stop the measurement, improved measuring accuracy. Be equipped with the movable grid in the slip vernier 3, be equipped with the fixed grid in the blade 2, the slip of slip vernier 3 makes the electric capacity between the movable grid and the fixed grid be the regularity change along with the change of the two relative displacement, is equipped with liquid crystal display 5 on the slip vernier 3 for the distance between fixed measuring claw 1 and the movable measuring claw 6 is measured in real time to the real-time demonstration, effectively improves on-the-spot operative employee's accuracy and the convenience of reading data.
In addition, the fixed measuring claw 1 and the ruler body 2 can be formed into an integral piece, and the fixed measuring claw 1 and the ruler body 2 can also be fixedly connected in a welding mode.
The section of the fixed measuring claw 1 is shaped into a semicircular arc or a one-third circular arc, so that the fixed measuring claw can be well attached to the outer diameter of a tundish nozzle, and the measuring accuracy is improved.
When measuring the centering nature of middle package mouth of a river relative crystallizer, the operative employee slides slide vernier 3 earlier to keeping away from 2 initiating terminals of blade, then can block middle package mouth of a river external diameter with fixed measuring claw 1, slide vernier 3 slides and makes movable measuring claw 6 block the crystallizer edge, observe bubble spirit level 4, adjustment blade 2 for slide caliper rule is in the horizontality all the time, reads data from LCD 5 on the slide vernier 3 again, also can read data through scale 7 on the blade 2 when LCD 5 does not have the electricity.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
