Abstract
A detection device for an electrode circle of an electric furnace aims to quickly and accurately detect that whether an electrode circle meets a tolerance requirement or not. The detection device comprises a cone, a bearing ring, a vertical positioning plate, a horizontal positioning plate, a rear positioning plate, a rotary measuring scale, a rotating shaft, a standard point pointer, a maximum tolerance size nail and a minimal tolerance size nail, wherein the cone with the point thereof as the electrode circle is upwardly arranged; the bottom surface circle of the cone is arranged in the bearing ring; being combined with the vertical, the horizontal and the rear positioning plates, the bearing ring is placed in an electrode clamp; a pin hole is formed at the center of an electrode circle of the vertical positioning plate; the rotary measuring scale is inserted into the pin hole via the rotating shaft and is linked with the vertical positioning plate; a size graduation is adhered on the rotary measuring scale; and the standard point pointer, the maximum and the minimum tolerance size nails respectively show the positions of the diameter of a standard electrode circle, as well as the maximum and the minimum tolerances.
Description
Technical field
The utility model relates to a kind of metallurgical equipment testing tool.
Background technology
There is direct relation in distance with arc length, arc temperature etc. between metal smelt electric furnace, ladle refining (LF) the stove three-phase electrode, affects the safety and steady operation of electrical network simultaneously, and its controlling index is i.e. three the triangle circumscribed circle diameter tolerances that the electrode center of circle is formed of utmost point heart circle; Install, large-scale maintenance all must detect the adjustment electrode circle diameter, extract electrode after, the electrode jaw internal diameter in spring action line direction less than electrode diameter; So can not look for the center of circle with the right-angled intersection method, generally, draw triangle according to distance between three centers of circle through repeatedly measuring ability calibration electrode home position; The median of a triangle intersection point that draws is the round heart of the utmost point heart; Draw out circumscribed circle, measure diameter, judge that then the three-phase electrode center is whether in the electrode circle diameter margin tolerance of regulation; In the adjustment process; Sometimes need carry out so several times loaded down with trivial details measurement, picture, computation process, whole process need 40-60 minute, every adjustment once need repeat work once like this.
Summary of the invention
The utility model purpose is can quick and precisely draw utmost point heart circle whether to meet tolerance, directly reads the amount of deflection, the electric furnace electrode utmost point heart circle pick-up unit of the detection at any time that is in course of adjustment.
The utility model comprises cone, sustained ring, longitudinal register plate, located lateral plate, rear position plate, wheel measuring chi and rotating shaft, standard point pointer, maximum allowance size nail and minimal tolerance size nail; The cone epiconus that makes progress is the electrode center of circle; Cone bottom surface circle is positioned in the sustained ring; And cooperate with sustained ring; Sustained ring and longitudinal register plate, located lateral plate, rear position plate are combined, and are positioned over to come the accurate keeper electrode center of circle in the electrode clamping, and this part three-phase structure all is identical; The round heart of longitudinal register plate heart position is provided with pin-and-hole; The wheel measuring chi inserts in the pin-and-hole through rotating shaft and connects with the longitudinal register plate; Be pasted with size scale on the wheel measuring chi, standard point pointer, maximum allowance size nail and minimal tolerance size nail indicate standard utmost point heart radius of circle, maximum radius tolerance and least radius tolerance position respectively.
The utility model is a definite value according to every electric furnace, L F stove three-phase electrode utmost point heart radius of circle and tolerance; Three-phase electrode center perfect condition is an equilateral triangle; Atria bar center line intersection point is the utmost point heart center of circle; So be fixed on the phase upper bracket can be on this line the round heart of the measurement and positioning utmost point heart and theoretical radius, serve as the swingle that axle is made mark cun scale with institute's centring, make marks at standard utmost point heart radius of circle and plus-minus tolerance place.When each installation, maintenance; Measure drawing, computation process that adjustment utmost point heart circle is removed very complicated from, only need in 5 minutes, just can quick and precisely draw utmost point heart circle and whether meet tolerance; Can directly read the amount of deflection, and the detection at any time that can be in course of adjustment.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, cone, 2, support ring, 3, the longitudinal register plate, 4, maximum allowance size nail, 5, the standard point pointer, 6, minimal tolerance size nail, 7, the wheel measuring chi, 8, rotating shaft, 9, rear position plate, 10,11, the located lateral plate, 12, the electrode orienting lug.
Embodiment
Be positioned over the centralized positioning combination that has pin-and-hole on the longitudinal register plate 3 on the middle phase electrode jaw; The groove fit of rear position plate 9 and electrode orienting lug 12; Sustained ring 2 is combined with longitudinal register plate 3, located lateral plate 10,11, rear position plate 9 and is positioned in the electrode clamping; Other two phases locating devices also are positioned over respectively separately in the clamper, and three cone 1 epiconuses upwards are placed in the sustained ring 2 respectively, confirm that line weighs down point and is every phase electrode center of circle; Wheel measuring chi 7 is installed on the longitudinal register plate 3; Wheel measuring chi 7 is rotated in rotating shaft 8 around the center of circle; Whether observe three lines bob points follows closely between 6 at maximum allowance size nail 4 and minimal tolerance size; Thereby judge whether that actual utmost point heart radius of circle error meets tolerance, reads the amount of deflection through scale, for next step adjustment provides foundation.Standard point pointer 5 is between maximum allowance size nail 4 and minimal tolerance size nail 6.
