Abstract
The utility model relates to a device for measuring the thickness of the slag at the top of a steel ladle, belonging to the technical field of metallurgical continuous casting and comprising a chassis (1), a lead-in pipe (2) and a handle (3), wherein the lead-in pipe (2) is welded on the chassis; and the handle (3) is welded at the central position of the chassis. The device has the advantages of being capable of ensuring verticality of slag wires and molten steel level, being convenient, fast and safe in operation and being capable of measuring the thickness of the slag at the top of the steel ladle accurately.
Description
Technical field
The utility model belongs to the metallurgical continuous casting technical field, and a kind of thick device of ladle top slag slag of measuring particularly is provided.
Background technology
Ladle top slag comes from the following slag of converter in tapping process, because the ladle top slag oxidisability is stronger, the oxygen in the refining treatment process in the slag of top can be transferred to molten steel and cause the secondary oxidation of molten steel, reduces the degree of purity of molten steel.For reducing the pollution of ladle top slag to molten steel, the following quantity of slag that detects each stove is one of efficiency index of weighing the converter tapping operant level, can also further follow the tracks of follow-up slab quality the following big heat of the quantity of slag simultaneously.The means of measuring ladle top slag at present are will survey the slag silk to insert in the molten steel, extract after 10 seconds, and the part that enters molten steel is melted, and measures the part of dry slag, is ladle top slag thickness.But find that in measurement the survey slag silk of insertion molten steel can't guarantee vertical with the molten steel face, the angle of surveying slag silk and molten steel face fluctuates between 45 °-90 °, and artifical influence factor is too big, can't guarantee the accuracy of measuring.
Summary of the invention
The purpose of this utility model provides a kind of thick device of ladle top slag slag of measuring, and solves the inaccurate problem of ladle top slag thickness measure, has realized accurate measurement ladle top slag thickness, and is easy to operate, degree of accuracy height.
The utility model comprises chassis (1), ingress pipe (2), handle (3); Ingress pipe (2) is welded on the chassis, and handle (3) is welded to the centre on chassis.
The chassis is circular, adopts corrosion resistant plate, diameter phi 200mm, thickness 5mm,
Ingress pipe is the steel pipe of long 3.5m, diameter phi 10mm, is welded on the chassis, at bolt of ingress pipe middle part welding, is used for fixing and surveys the slag silk.
Handle is a round steel pipe, curves the angle of 140-160 degree as required, is welded to the centre on chassis.
It is vertical with the molten steel face, easy to operate that the novel advantage of this use is to guarantee the surveying slag silk, quick, safety, and it is thick to measure bag top slag exactly.
Description of drawings
Fig. 1 is the utility model structural representation, wherein, and chassis 1, ingress pipe 2, handle 3.
Fig. 2 is the utility model vertical view.
The specific embodiment
Figure, Fig. 2 a kind of specific embodiment of the present utility model.
The utility model comprises chassis 1, ingress pipe 2, handle 3; Ingress pipe 2 is welded on the chassis, and handle 3 is welded to the centre on chassis.
Adjust the angle of bend of steel pipe according to the position of ladle and operating platform, chassis 1 can keep level angle to be advisable when standing in the operating platform operation with operating personnel.To survey the slag silk and penetrate ingress pipe 2, and make the length that passes chassis 1 be not less than 500mm.To survey the slag silk with set bolt and fix, operating personnel use novel level to stick the ladle top slag top of the slag this when measuring, extract after 10 seconds, and be benchmark with 1 bottom surface, chassis, measure the thickness that unfused survey slag silk is ladle top slag.
