The special tool comprises an upper rod and a lower rod, wherein measuring feet symmetrically and outwardly tilted are arranged at the front ends of the upper and the lower rods respectively; inner angle measuring plates are symmetrically and inwardly arranged at the rear ends of the upper and the lower rods respectively; the upper and the lower rods are equal in length; and hinged points at the rear half sections of the upper and the lower rods are hinged via hinged devices. The special tool provided by the utility model has the advantages that the structure is simple, the use is convenient, the erosion thickness of the steel converter lining bricks at each position of the hearth can be accurately measured, a furnace maintenance is reasonably arranged according to the erosion condition, the fettling frequency is reduced, the service life of the furnace is prolonged, the consumption of the fire-resisting material per ton steel is decreased, and the labor intensity of staff is reduced.
Description
Technical field
The utility model belongs to the special tool of measuring steel-making converter backup lining brick residual thickness, particularly a kind of special tool of measuring size of burner hearth.
Background technology
Along with the slag splashing process application; The backup lining brick erosive velocity reduces; Converter lining life is improved constantly (the steel-making 40t of a subsidiary factory converter lining life reaches about 20000 stoves); Under the high temperature each position magnesia carbon brick corroding thickness in the stove is only judged by rule of thumb do not have advanced detecting instrument to detect the backup lining brick residual thickness.Especially converter two inboard slag linings only depend on Gunning refractory, spatter slag blanket and safeguard, before the converter, stove back erosive velocity is fast., furnace lining, under the smelting state, will produce the stove accident of wearing when reaching safe-guard line if observation is not careful.
Summary of the invention
The purpose of the utility model is to provide a kind of special tool of measuring size of burner hearth, and it is simple in structure, and is easy to use; Can accurately measure each position backup lining brick corroding thickness of burner hearth,, rationally arrange body of heater to safeguard according to erosion condition; Reduce the fettling number of times; Improve furnace life, reduce the consumption of ton steel refractory materials, reduce personnel labor.
The purpose of the utility model is achieved in that a kind of special tool of measuring size of burner hearth; Special tool is made up of upper boom and lower beam; The front end of upper boom and lower beam is being provided with the outward-dipping measurement pin of symmetry respectively; The rear end of upper boom and lower beam is being provided with the inside interior dihedral of symmetry respectively and is measuring plate, the equal in length of upper boom and lower beam, and be hinged together through the articulated mounting that is provided with on the pin joint of its second half section.
When adopting the utility model to measure size of burner hearth: 1, body of heater is shaken to 90 ° of positions of level stop, aiming at the fire door position of center line to the fire door window; 2, will measure the burner hearth instrument and be placed on the fire door scroll wheel and advance burner hearth, the position that will measure stop, opening burner hearth instrument lets outward-dipping measurement pin brick in the contact oven gently, and measures and measure between the pin outer end and open distance A; 3, after the amount burner hearth finishes,, when the outer end distance be A, measure between the plate the inner in measuring and open apart from being size of burner hearth B at platform opening burner hearth instrument; 4,,, calculate the backup lining brick corroding thickness according to the new furnaceman size of planting through size of burner hearth B.
Use through to amount burner hearth instrument has following advantage: 1, accurately grasp each position backup lining brick corroding thickness in the burner hearth; 2, according to erosion condition, rationally arrange body of heater to safeguard, reduced the fettling number of times, reduced the consumption of ton steel refractory materials, reduced staff labor intensity; 3, rationally arrange to spatter the slag rate, guarantee type of furnace rule, make smelting process steady, reduce the converter splash, improve recovery rate of iron, reduced iron and steel stock consumption; 4, rationally arrange body of heater to safeguard, improve the slag splashing effect, improve furnace life, reduce the consumption of refractory materials.
Through on probation, it is accurate to measure size of burner hearth at first steelworks for the utility model at present, and effect is remarkable, and also safety is retired to make the 40t converter lining life reach 32860 stoves.
The utility model is simple in structure, and is easy to use, can accurately measure each position backup lining brick corroding thickness of burner hearth; According to erosion condition, rationally arrange body of heater to safeguard, reduced the fettling number of times; Improve furnace life, reduced the consumption of ton steel refractory materials, reduced personnel labor.
