Molten steel scale calibration device and use method thereof

Abstract

The invention relates to a molten steel scale calibration device and a use method thereof, and belongs to the technical field of equipment calibration. The device comprises a base fixed on the molten steel scale, a concave conical hole is formed in the top surface of the base, inclined pull lugs are welded to the two side surfaces of the base, first vertical pull lugs are welded to the fixed surface of the base, a turbine worm box is fixed to the back surface of the base, a belt wheel sleeves a turbine shaft of the turbine worm box, a flat key is inserted into the turbine shaft, and a base plate is fixed to the end surface of the turbine shaft. A stress frame is fixed to the top face of the base, a second vertical pull lug and a hydraulic cylinder are fixedly connected to the bottom plane of the stress frame, the first vertical pull lug and the second vertical pull lug are connected through a vertical pull rod, a bearing shaft is inserted into a hole of the stress frame, two diagonal pull rods are connected with the bearing shaft and the diagonal pull lugs, and a steel wire rope is fixed to the stress frame and fixed to a wheel groove of a belt wheel. An oil inlet of the hydraulic cylinder is sequentially connected with an oil pipe, a throttling valve and a hydraulic handle, a positioner groove is formed in the metering rail, and an end face inner hole of the positioner is perpendicular to a piston rod of the hydraulic cylinder. The device is convenient and reliable in calibration, simple in structure, easy to use and low in manufacturing cost, the calibration time is shortened, the operation safety is improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a molten steel scale calibration device and a using method thereof, belonging to the technical field of equipment calibration. Background technique [0002] In today's society, the old-fashioned mechanical scales have been eliminated, and the accuracy levels of measurement are distinguished according to the objects to be weighed and the weights. The steelmaking plant has several electronic scales for measuring the weight of ladles. This scale is an important production process measurement equipment and belongs to the 0.5-level control equipment in the factory. It needs to be verified and calibrated regularly. The calibration method currently used requires a lot of manpower, manpower to rotate the bracket and elastic bolts, and then transport the 50-ton mechanical jack to the metering rail, and manually shake the mechanical jack to the set value. The calibration process is time-consuming and laborious. Contents of the inventio...
