Embodiment Construction

[0017] First of all, the design original intention of the present invention is explained, because existing weighing devices all adopt four supporting point weighing methods or three-point hinged weighing methods; The flatness of the points, the verticality and steel strength of the entire equipment frame are very high, and there are high requirements for the basic accuracy of the equipment. Otherwise, the sensors at the four support points will be unevenly stressed and overloaded, which will easily affect The accuracy of continuous weighing in the smelting process leads to the uncontrollability of the automatic melting rate smelting method; while the three-point hinged weighing method is connected by a hinge and its external fixed frame, but the external fixed frame is not included in the scale. Therefore, the accuracy of its continuous weighing will be affected by the pulling force of the external fixed frame; in order to improve the accuracy of weighing and make it more suita...

Abstract

The invention discloses an electroslag furnace high-precision suspension frame weighing device. The weighing device comprises a bottom frame playing a supporting role, wherein three weighing sensors are arranged on the bottom frame, the three weighing sensors are not located on the same straight line, a suspension frame playing a role in connection is arranged above the weighing sensor, and threesupporting legs are further arranged above the suspension frame. The weighing device is advantaged in that the three weighing sensors which are not located on the same straight line are used for weighing, and thereby the installation and manufacturing requirements of equipment are reduced, the three sensors are enabled to be stressed uniformly and reliably through employing the principle of threepoints and one surface, and high-precision weight data is provided for smelting control.

Description

technical field [0001] The invention relates to the technical field of special metallurgical equipment, in particular to a high-precision suspension frame weighing device for an electroslag furnace. Background technique [0002] In my country's traditional single-column support-arm type and double-column rotating support-arm type double-station electroslag furnace, the support arm clamp clamps the dummy electrode and the metal electrode, and the control transmission device rotates the T-shaped screw to drive the roller cantilever to move up and down to complete the smelting . [0003] The weighing devices of domestic research and design or imported coaxial electroslag furnaces all use four support point weighing methods or three-point hinged weighing methods; The flatness of the force point, the verticality of the entire equipment frame and the steel strength requirements are very high, and the basic accuracy of the equipment is also very high, otherwise the sensors at the f...
