Description
Technical field
The present invention relates to a kind of system and method, specifically, relating to a kind of system and method for monitoring self-baking electrode calcined state, belong to metallurgical and chemical field.
Background technology
Self-baking electrode block type electrode is stuck with paste load in electrode container, forms electrode through roasting.The skin of self-baking electrode is the electrode container be made up through welding of the steel plate that 2 ~ 3mm is thick, and block type electrode is stuck with paste and is regularly added in electrode container.Along with the carrying out produced, electrode consumes gradually, and block type electrode is stuck with paste and moved down, and progressively softens, and form molten state electrode paste, at higher temperature effect Using Coke-oven, be finally converted into the electrode of conduction, roasting process carries out continuously.Because technique is simple, cost is low, self-baking electrode is widely used in ferro-alloy furnace, furnace of calcium carbide, Yellow phosphorus furnace etc.
Self-baking electrode is the important component part that electric furnace is produced, and only has roasting normally to run, and guarantee is produced and carried out smoothly.During smelting, electrode consumes gradually, needs constantly to press electrode.If the speed that presses of electrode is greater than rate of roasting, then there is stream paste, soft disconnected accident in the easy lower edge at Conducting copper tile, and now self-baking electrode is deficient roasting.If self-baking electrode rate of roasting is too fast, namely rate of roasting is greater than the speed of pressing, then Conducting copper tile thorn fire, electrode hard broken accident easily occur, and now self-baking electrode was roasting.
Because self-baking electrode is wrapped in device interior, directly internal state cannot be observed from the outside.Current operating personnel are that dependence experience is inferred, then operate.Only rely on the supposition of experience cannot make actual calcined state to judge accurately, there is potential safety hazard, therefore personnel at all levels's casualty accident also occurs often.
Specifically, in electric furnace production process, operating personnel according to electrode current, the working of a furnace, observation electrode surface color, by experience, the calcined state of self-baking electrode is assessed.This assessment is indirectly, cannot make judging accurately actual calcined state.If it is improper to assess, just accurately cannot judge that self-baking electrode is in deficient calcined state, was still in calcined state.If be in deficient roasting, the operation that presses rashly causes soft disconnected, stream to stick with paste, and gently then causes of short duration blowing out, affects the utilization of capacity, heavy then cause blast, casualties.If be in roasting, take respective handling measure not in time, then easily cause thorn fire, firmly disconnected accident.
Summary of the invention
In order to solve above-mentioned prior art weak point, the object of the present invention is to provide a kind of system for monitoring self-baking electrode calcined state, to overcome the defect of prior art.
In order to achieve the above object, the invention provides a kind of system for monitoring self-baking electrode calcined state, described system comprises actuating mechanism, controller, self-baking electrode and temperature transducer.Described actuating mechanism is bonded in described self-baking electrode to prevent described temperature transducer for adjusting and controlling the position of described temperature transducer in described self-baking electrode.Wherein, described controller is for receiving system signal and to the instruction of described actuating mechanism output action; Described self-baking electrode is made up of electrode container, block type electrode paste, molten state electrode paste and electrode, the state of described electrode container internal electrode paste is from top to bottom followed successively by described block type electrode paste, described molten state electrode paste and described electrode, and the outside of described electrode container is provided with several Conducting copper tile equably; The bottom of described temperature transducer is arranged in roasting region, and for measuring the temperature in roasting region, the temperature signal of described temperature transducer finally flows to controller.
Preferably, described system signal comprises and presses signal for what control to press electrode container, described in press the command signal that signal is electrode control system; For the lifting signal that control electrode system rises and declines, described lifting signal is the command signal of electrode control system; For the temperature signal of temperature transducer feedback and the position signalling for temperature transducer.
