Main ditch refractory material erosion monitoring and early warning system

Abstract

The invention relates to a main ditch refractory material erosion monitoring and early warning system which comprises a main ditch, five temperature sensors, a programmable controller and an upper computer database. One temperature sensor is pre-buried in the bottom of the main ditch, two temperature sensors are pre-buried in each of the two sides of the main ditch, each temperature sensor is connected with the programmable controller, and the programmable controller is connected with the upper computer database. The five temperature sensors are arranged at the main ditch of a blast furnace casting house, temperature signals are accessed to the programmable controller, and the programmable controller calculates the erosion degree of a refractory material through a model by integrating information such as a temperature monitoring value, the material of the refractory material and the structure of the main ditch and displays the erosion degree in different colors on a monitoring pictureof an upper computer. The erosion degree of the refractory material in a casting house area is automatically monitored and early warned, defects that in the past, the manual detection precision is poor, and real-time monitoring cannot be achieved are overcome, and a probability of major personal injury accidents caused by the fact that a main ditch burns through spilled iron is reduced.

Description

technical field [0001] The invention belongs to the technical field of blast furnace casting plant monitoring, and in particular relates to a monitoring and early warning system for main channel refractory erosion. Background technique [0002] With the improvement of the blast furnace process operation level and the upgrading of equipment, the repair cycle of the blast furnace has been gradually extended from the original 60-90 days to 150 days. For some blast furnaces with stable operation and advanced indicators, the regular repair cycle can even reach more than 180 days. With the increase of blast furnace utilization rate and load, and the extension of regular maintenance period, the corrosion degree of blast furnace refractory materials by molten iron often intensifies within a regular maintenance period. Moreover, the casthouse area of ​​the blast furnace is a densely populated place. Once the molten iron leaks, it is very easy to cause major safety and equipment acci...
