Device and method for measuring furnace top charge level of bell-less blast furnace

Abstract

The invention provides a device and a method for measuring a furnace top charge level of a bell-less blast furnace. The device comprises a blast furnace stock rod device. A stock rod is provided with a laser range finder, a gyroscope and a wireless communicator; the laser range finder and the gyroscope are arranged on the same plane in parallel side by side and form the same fixed included angle with the vertical charge level of the blast furnace stock rod device; and measurement data signals are sent to an external computer by the wireless communicator. The measurement method comprises the following steps: (1) starting all devices to enable the laser range finder to move downwards along the stock rod; (2) sending the measured data to the computer, and saving the descending height data ofthe stock rod to the computer; and (3) carrying out calculation by the computer by utilizing a trigonometric function formula, and saving a result. By adopting the device and the method for measuringthe furnace top charge level of the bell-less blast furnace, the multi-angle omnibearing stereoscopic measurement can be carried out on the shape of the furnace top charge level of the bell-less blast furnace without modifying furnace top equipment or mounting auxiliary measurement equipment. Moreover, the measurement process is safe and reliable, the measurement result has high precision, and the real-time performance is strong.

Description

technical field [0001] The invention belongs to the technical field of blast furnace ironmaking detection, and in particular relates to a measuring device and a measuring method for a bellless blast furnace top material level. Background technique [0002] The bellless furnace roof is widely used in the production of modern large blast furnaces because of its reliable sealing, flexible cloth distribution and long service life. The initial distribution of the blast furnace charge in the furnace has a great effect on the gas flow distribution of the blast furnace, the utilization of gas, the forward movement of the blast furnace and the longevity of the blast furnace. The measurement of the top charge level of the blast furnace is a work that must be carried out before the blast furnace is started. It is the premise and guarantee of reasonable fabrics. However, the continuity, closure and danger of large blast furnace production have brought great difficulties to the measurem...

AI Technical Summary

Problems solved by technology

However, this patented technology needs to drill holes on the top of the blast furnace. There are many auxiliary equipment such as radar and cooling installed, and the maintenance and use costs are high. After the blast furnace is opened, the measurement accuracy is inevitable due to the high temperature and dust in the blast furnace. are affected
