Abstract

The invention relates to an automatic weighing device and specifically an automatic weighing device for a molten iron reladling station. The automatic weighing device comprises a torpedo ladle, a molten iron ladle, an electric motor controlling the torpedo ladle to pour out molten iron, an angle sensor used for measuring an inclination angle of the torpedo ladle, a control switch, a weighing instrument used for measuring the weight of the molten iron in the molten iron ladle and a control chip, wherein the control chip is in electric signal connection with the control switch, and the bottom part of the torpedo ladle is connected with a rotating shaft of the electric motor in a fixed manner; the torpedo ladle is held still for K*q*q1 seconds after being inclined at a maximum angle from a vertical position, and then the torpedo ladle is returned to the original vertical position. The beneficial effects of the automatic weighing device are that the molten iron ladle can be automatically weighed on line when receiving the molten iron from the torpedo ladle, manual confirmation is not needed, requirements for fast-paced production can be met, and requirements for measurement precision in the field of steel-making technologies can also be satisfied.

Description

A kind of automatic weighing device for molten iron ladle pouring station

Technical field

The present invention relates to a kind of automatic weighing device, specifically a kind of automatic weighing device for molten iron ladle pouring station。

Background technology

Molten iron ladle pouring station is the necessary links during large-scale steel mill produces, and for receiving the fish torpedo ladle molten iron in ironworks, and pours hot-metal bottle into, after weighing, pours pneumatic steelmaking into。Molten iron weighing result is that automation of converter steelmaking model calculates required significant data, directly influences control accuracy and the STEELMAKING PRODUCTION rate steel-making cost of automatic Steelmaking system。In traditional steel making operation, it is common to adopting manual method to gather above-mentioned weight of molten iron data, owing to influence factor is more so there is error, directly influencing the control accuracy of automatic Steelmaking。Therefore, it is achieved ladle pouring station molten iron automatic weighing, pneumatic steelmaking production is had great importance。

Summary of the invention

The technical problem to be solved is: how to realize Automated condtrol and realizes hot-metal bottle reception molten iron is controlled and is measured。

The technical solution adopted in the present invention is: a kind of automatic weighing device for molten iron ladle pouring station, including fish torpedo ladle, hot-metal bottle, control fish torpedo ladle and topple over the motor of molten iron, measure the angular transducer at fish torpedo ladle angle of inclination, control switch, for measuring the weighing instrument of the upper weight of molten iron of hot-metal bottle, control chip, the control chip signal of telecommunication connects control switch, the bottom of fish torpedo ladle and the rotating shaft of motor are fixed together, after fish torpedo ladle tilts to maximum position from upright position, after postponing the k*q*q1 second, fish torpedo ladle returns to upright position from tilting maximum position, motor is uniform speed electric motor, the required total iron water amount of q hot-metal bottle, q1 is that fish torpedo ladle tilts to maximum position process molten iron and topples over the iron water amount of hot-metal bottle from upright position, k is constant。

The invention has the beneficial effects as follows: realize accepting hot-metal bottle on-line automatic weighing when by ferrum of fish torpedo ladle molten iron, it is not necessary to carry out manual confirmation, namely meet the fast pace requirement of production, in turn ensure that the measuring accuracy demand of process for making。

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention；

Fig. 2 is motor of the present invention and controls switch schematic diagram；

Wherein, 1, fish torpedo ladle, 2, motor, 3, hot-metal bottle, 4, weighing instrument, 5, switch is controlled。

Accompanying drawing explanation

Fish torpedo ladle is when toppling over molten iron to hot-metal bottle, torpedo tank will be occurred to topple, when tank body just starts to topple, hot-metal bottle, but without receiving molten iron, is slack tank state, along with molten iron is poured over hot-metal bottle, when reaching the amount that certain amount meets next procedure electric furnace or pneumatic steelmaking requires, fish torpedo ladle tank body starts to initial perpendicular bit reversal, and the flow at this moment flowing into hot-metal bottle starts to reduce, stopping completely when reaching vertical position, hot-metal bottle is in weight can-like state。As long as from the foregoing, it will be observed that can pass through to add equipment state when some equipment follows the tracks of above-mentioned fish torpedo ladle to molten iron, in conjunction with the vehicle scale weight signal residing for hot-metal bottle, so that it may reach the purpose of automatic Weighing。

As depicted in figs. 1 and 2, during beginning, fish torpedo ladle is in vertical position, first the iron water amount (namely hot-metal bottle needs the iron water amount accepted) toppled over is needed to input control chip fish torpedo ladle, control chip controls switch, make a1 and a2, b1 and b2 is respectively communicated with, such driven by motor motor shaft and then drive fish torpedo ladle start to tilt, tilt to inclination maximum (in Fig. 1 dotted line position), keep the k*q*q1 second, then, control chip controls switch makes a1 and b2, b1 and a2 is respectively communicated with, such driven by motor motor shaft and then drive fish torpedo ladle start to return to upright position, fish torpedo ladle is toppled over molten iron and is completed, motor is uniform speed electric motor, the required total iron water amount of q hot-metal bottle, q1 is that fish torpedo ladle tilts to maximum position process molten iron and topples over the iron water amount of hot-metal bottle from upright position, k is that constant can be obtained by test of many times。

Being 80 tons for fish torpedo ladle capacity, hot-metal bottle capacity is 2.5 tons, and when fish torpedo ladle is toppled over, slewing rate is 0.6 rev/min, and k value is 1.23。

Claims

1. the automatic weighing device for molten iron ladle pouring station, it is characterized in that: include fish torpedo ladle, hot-metal bottle, control fish torpedo ladle and topple over the motor of molten iron, measure the angular transducer at fish torpedo ladle angle of inclination, control switch, for measuring the weighing instrument of the upper weight of molten iron of hot-metal bottle, control chip, the control chip signal of telecommunication connects control switch, the bottom of fish torpedo ladle and the rotating shaft of motor are fixed together, after fish torpedo ladle tilts to maximum position from upright position, after postponing the k*q*q1 second, fish torpedo ladle returns to upright position from tilting maximum position, motor is uniform speed electric motor, the required total iron water amount of q hot-metal bottle, q1 is that fish torpedo ladle tilts to maximum position process molten iron and topples over the iron water amount of hot-metal bottle from upright position, k is constant。
