Description
Technical field
The present invention relates to metallurgical equipment manufacturing technology field, particularly detection device of corrosion of induction furnace bottom aeration element.
Background technology
In order to satisfy the needs of production and scientific research, need bottom-blowing air feed element molten steel air feed in stove be installed at the furnace bottom of induction furnace and carry out the bottom blowing stirring, to satisfy the needs that molten steel stirred refining and decarburization.When induction furnace was installed bottom-blowing air feed element and blown in stove, particularly in stove during oxygen blast, because violent souring in high temperature, oxidation and the stove, the wear and tear speed of air supply device was difficult to grasp, and caused burning out of air supply device and caused the bleed-out accident.Because the special construction of induction furnace: capacity is less, and heat size is smaller, and furnace bottom is thinner, and eddy current is big, whether the air supply intensity in the stove is accurately required strict.Refining is different with general method, and air supply intensity can not be too big, otherwise will cause the interior molten steel material of stove to mix acutely, and splash strengthens, and the loss of steel increases, but also makes security incident easily; Air supply intensity again can not be too low, if air supply intensity is too low, stirring intensity is too little, does not reach the purpose of refining and decarburization, but also cause the air feed original paper to burn out easily, thereby often cause the generation of bleed-out accident.Still there is not to be applicable to well the device of corrosion of induction furnace bottom aeration element detection in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of detection device of corrosion of induction furnace bottom aeration element, be used to solve owing to the speed of deteriorating of air supply device at the bottom of the induction furnace is difficult to grasp, often causes air supply device to burn out to cause the technical barrier of bleed-out accident.
Detection device of corrosion of induction furnace bottom aeration element of the present invention is provided with the detection probe of deteriorating around the induction furnace bottom air supply device, the quantity of the detection probe of deteriorating can be decided as required, can install 2～18 or more as 30, the detection probe of deteriorating is connected with transmitter by connecting plug-in unit, transmitter is connected with computer processing system, the detection probe of deteriorating sends the temperature signal of relevant position around the bottom-blowing air feed element that records to transmitter, the transmitter weak electric signal that detection probe records that will deteriorate is transformed into standard signal, again standard signal is sent to computer, computer is equipped with the software systems of handling this signal, can receive in real time, handle this signal, realize the deteriorate detection of the speed and the position of deteriorating of air supply device at the bottom of the induction furnace.
Around bottom-blowing air feed element, the detection probe of deteriorating is installed every certain gap length.When the nearest forward's probe of distance furnace bottom burns out, checkout gear generation alarm signal, the position of deteriorating of reminding operator's spray gun this moment.The detection probe of respectively deteriorating sends its position temperature signal to transmitter and display unit in real time, makes the operator grasp the temperature of spray gun each point and the position of deteriorating of spray gun at any time, guarantees not burn out the bleed-out accident that causes because of spray gun in the smelting process.The operator can in time regulate the size of refrigerating gas tolerance according to the speed of forward's idol temperature rise speed, the ratio that also can regulate oxygen and inert gas, thus assurance prolongs the service life of spray gun, guarantees that again spray gun does not stop up simultaneously.
The detection probe of deteriorating is made of thermocouple.Transmitter is transformed into standard signal with the weak electric signal that thermocouple records, and sends computer processing system to.Computer processing system can adopt any system with A/D sampling function to constitute, and as Programmable Logic Controller (PLC), has the computer system of A/D capture card, has the intelligence instrument of A/D sampling etc.The detection probe of deteriorating thermocouple also can directly insert the computer system of the A/D capture card with temperature sampling without transmitter.
When deteriorating, spray gun reaches a certain section thermocouple place, thermocouple is blown, the temperature of measuring is zero, but continue to deteriorate, may make thermocouple sintering again, again temperature value will be arranged, the computer system program comprises electric thermo-couple temperature and detects step, the alarm decision step, the temperature step display, the position display of deteriorating step, the alarming step of deteriorating, electric thermo-couple temperature detects step and detects each section electric thermo-couple temperature, show each section electric thermo-couple temperature sampled value by the temperature step display, after thermocouple blows, temperature value is zero, and the alarm decision step is caught thermocouple and is blown constantly, and is reported to the police by the alarming step of deteriorating, cancel simultaneously the measuring ability of this section thermocouple automatically, prevent to produce wrong report owing to sintering once more.The position display of deteriorating step shows the position of deteriorating.Also can realize the prompting of visualization, language by programming.Therefore, detection device of corrosion of induction furnace bottom aeration element computer processing system of the present invention has comprised the electric thermo-couple temperature checkout gear, the alarm decision device, temperature indicating device, lever position indicator deteriorates, warning device deteriorates, the electric thermo-couple temperature checkout gear detects each section electric thermo-couple temperature, show each section electric thermo-couple temperature sampled value by temperature indicating device, after thermocouple blows, temperature value is zero, the alarm decision device is caught thermocouple and is blown constantly, and report to the police by the warning device that deteriorates, cancel simultaneously the measuring ability of this section thermocouple automatically, prevent to produce wrong report owing to sintering once more.The lever position indicator that deteriorates shows the position of deteriorating.
When being particularly suitable under the induction furnace bottom oxygen condition bottom blowing spray gun being installed, this checkout gear uses, the smelting equipment that also can be used for other element with bottom-blowing, air supply device the deteriorate speed and the position of deteriorating can be conveniently grasped at the bottom of the induction furnace in its application, avoid air supply device to burn out, effectively the generation of breakout.
