Reversible semi-ladle temperature measuring and sampling device

Abstract

The invention discloses a reversible semi-ladle temperature measuring and sampling device, belongs to the technical field of converter steelmaking equipment, and is used for automatically performing temperature measuring and sampling on semi-steel. According to the technical scheme, two bearing seats are fixedly connected to a steel beam base, the two ends of a turning shaft are connected with thebearing seats through the turning bearings correspondingly, one end of the turning shaft is connected with a turning shaft driving device, the middle of a gun frame is vertically connected with the turning shaft, a temperature measuring gun and a sampling gun are mounted at the front end of the gun frame in a connecting mode, and a gun frame rotating device is installed at the rear end of the gunframe. The device is simple in structure and convenient to use, the gun frame can perform turning sampling and temperature measuring, meanwhile, the gun frame can rotate along the longitudinal axis of the gun frame, a sampler and a temperature measuring coupling head can be conveniently replaced, the space is saved, the operation is easy, the temperature measuring and sampling can carried out onthe semi-steel at the same time, the data error caused by manual operation is avoided, the working efficiency is improved, the labor intensity of operators is reduced, potential safety hazards are eliminated, and the device has excellent popularization and use value in the industry.

Description

technical field [0001] The invention relates to a half-ladle temperature measuring and sampling device, which belongs to the technical field of converter steelmaking equipment. Background technique [0002] In iron and steel enterprises, the dual method of vanadium extraction and steelmaking is an important method widely used in many molten iron vanadium extraction processes. This method uses two converters for production, one is a vanadium extraction converter, a movable or fixed spray gun is used to blow in pure oxygen or air, and the nozzle of the spray gun is blown in from the top, bottom or side of the converter, using the principle of selective oxidation , high-speed oxygen jets stir the vanadium-containing molten iron, oxidize the vanadium in the molten iron into stable vanadium oxides to produce vanadium slag, then recycle the vanadium slag, and then move the semi-steel to another converter for slag making and steelmaking. This method can obtain high-quality vanadiu...

Problems solved by technology

Under normal conditions, temperature measurement and sampling requires manual operation, but manual temperature measurement and sampling will cause some disadvantages due to human factors: first, the position and insertion depth of the temperature measurement and oxygen gun insertion point are difficult to meet the specified requirements; second, manual temperature measurement If the heating time is long, its stability will deteriorate, which will affect the accuracy of the data; moreover, the composition of the samples obtained by manual sampling fluctuates, and the rate of bad samples is high; finally, manual temperature measurement and sampling are labor-intensive and the environment is harsh, which is relatively dangerous , pose a threat to the personal safety and health of the operator

With the development of production, the automatic temperature measurement and sampling device has also been applied in production, but it is found in use that the existing automatic temperature measurement and sampling device still has some shortcomings: one is that the temperature measurement and sampling device is completely exposed to the The surface of the ladle is subjected to severe heat radiation, which shortens the service life of the device; second, it is difficult to install the probe of the automatic temperature measurement sampling gun, and the working surface of the staff is very close to the edge of the ladle, the environment is harsh, and there is a risk of personal safety; the third is temperature measurement Sampling uses the same gun body, which can only complete one task (temperature measurement or sampling) at a time, and the work efficiency is low; Fourth, the current automatic temperature measurement and sampling device has a complex structure and takes up a lot of space

[0005] In summary, the current state of manual temperature measurement and sampling and the existing automatic temperature measurement and sampling device are no longer suitable for the needs of production development. Problems to be solved
