Description
Technical field
The utility model relates to steel-making ladle technical field, particularly relates to a kind of device that is used to detect ladle liner thickness on the chassis.
Background technology
Ladle is being undertaken the important function of transporting molten steel in the STEELMAKING PRODUCTION process.Because molten steel is in the high temperature of about 1600 degree, and is very serious to the erosion of ladle liner.The ladle working environment is: the liquid steel temperature that bears is higher than die casting; The time of staying of molten steel in ladle prolongs; The agitaion that ladle liner self volatilizees and stands under high-temperature vacuum; The percussion that liner receives when accepting molten steel; Slag is to the erosion of liner.
The ladle liner erosion mechanism is: ladle liner is in use constantly by deterioration, and its mechanism is under the high temperature, due to the chemical erosion and mechanical erosion of molten steel and slag.Molten steel mainly is the SiO in Mn and the refractory brick in the steel at high temperature
2Chemical reaction takes place, generate MnO, and restore Si, ladle liner is produced the chemical erosion effect.In addition, MnO and secondary oxidation of steel that the MnO that chemical erosion produces, deoxidation produce, the FeO and the MnO that generate and be suspended in the steel react with refractory material again, generate low melting point, quicken the destruction of refractory material.The molten steel of heterogeneity is also different to the erosion degree of liner, and total trend is the reduction along with phosphorus content in the steel, the rising of tapping temperature, and corrosion function is stronger.Slag is particularly evident to the erosion of liner, when the slag of high temperature contacts with liner, owing to contain more FeO, CaO, Caf in the slag
2, MnO etc., the SiO in they and the refractory material
2, Al
2O
3Effect generates low melting point, fuses in the slag.Oxidisability is strong, and temperature is high, the slag of good fluidity, and corrosion function is stronger.The liner loss is also relevant with properties of refractories; Be lined with the crack or when not fine and close when interior; Slag will be penetrated in the slit soon and corrode, and the result forms and appears to very fine and close vitreous texture on the layer of surface, but this layer glass structure splits; The slit constantly enlarges, and has quickened the loss of liner.Simultaneously, the damage of liner and the masonry quality that corrodes also with ladle have much relations.
The structure of ladle is: ladle is made up of shell, reinforcement hoop, gudgeon, cast steel mouth and slide gate nozzle etc.The ladle shell is riveted with 20～45mm steel plate or is welded, and is drilled with the steam vent of some on the shell, so that when ladle baking, gets rid of the moisture in the refractory material, and the steam vent diameter is generally 10～20mm.Strengthening hoop is the waist employing steel loop banding of involucrum, and it plays stiffened shell, prevents the effect of involucrum distortion, and a ladle generally respectively welds one and strengthens hoop in the middle and upper part.A gudgeon is respectively adorned in the ladle both sides, and the position of gudgeon generally should be higher than the center of gravity 350～400mm after ladle fills with molten steel, makes ladle under condition of work, can keep balance.The mouth of a river is generally on the ladle bottom right side, if the common mouth of a river, the bag drain pan has pressing plate and urgent bearing pin in addition, in case nozzle brick is loosening; If slide gate nozzle, a datum plate vertical of position welding at the bag suitable mouth of a river, the end with the ladle center line, slide gate nozzle machinery just is installed on the datum plate.Tilting mechanism is installed one or two blocks of steel plates in the bag bottom usually, and its position, is convenient to cast and is finished to the bag feather edge at the bag end one end, pours the residue and residual steel into slag ladle.The bag leg is equipped with 3 bag legs in bag bottom, so that protection tipple and slide mechanism when being placed on the ground.Slide gate nozzle is the vitals of ladle, is fixed on the bag position corresponding with the mouth of a river, the end.
Ladle liner comprises, thermal insulation layer, and effect is insulation, reduces the heat transmission of liner to shell, thereby prevents that involucrum at high temperature is out of shape; Permanent layer, effect are to corrode when thin when working lining, prevent molten steel and burn out involucrum during from the working lining leakage, thereby improve Bao Shou; Working lining directly contacts molten steel and slag, bears the high temperature and the chemical erosion of molten steel and slag, therefore its material capability is had relatively high expectations.
Because the cylinder-packing at ladle slag line place is the easiest to be impaired, ladle is after through one period service time, if operating personnel accurately do not judge the cylinder-packing thickness of ladle; Ladle " rubescent " can occur or wear the bag accident; Burn out equipment or design personal safety, if can in time or accurately measure the variation of the cylinder-packing of ladle, i.e. scaling loss situation at the stove labour device of ladle; Just can know this moment, whether ladle was in safe period, can avoid the generation of security incident.But human eye is difficult to sometimes find trickle crack that this has caused great potential safety hazard in the face of hyperthermia radiation.
At present, in the STEELMAKING PRODUCTION process, common way is that certain safe handling number of times is set, the maintenance of when ladle arrives these access times, rolling off the production line, this actual significant wastage that causes refractory material.Therefore, press for a kind of ladle liner on-line equipment.
