Converter sliding plate inter-plate refractory erosion inspection and inter-plate cold steel cleaning tool and method

The invention discloses a converter sliding plate inter-plate refractory erosion inspection and inter-plate cold steel cleaning tool and method, comprising the following steps: a converter is shaken to a vertical zero position after converter tapping, and is stopped for 10 seconds, so that steel slag accumulated in a tapping hole flows back into the converter; the converter is shaken to the 26-degree position behind the converter, a sliding plate is opened, a cleaning tool goes deep into the sliding plate of the converter along a steel outlet outside a fire damper behind the converter and strikes towards the side of the fire damper, and semi-crescent cold steel formed after molten steel left between the sliding plates of the converter due to refractory erosion is solidified is hooked out; if the cold steel cannot be hooked out at one time, repeatedly operating for multiple times to hook out the cold steel; a cleaning tool radially and repeatedly passes through the plates, and the size of erosion gaps between
