Technical Field
[0001] The utility model belongs to the technical field of digital mud mark making, in particular to a digital mud mark making device for a blast furnace mud gun. Background Art
[0002] At present, the mud volume of many blast furnace mud guns in China is indicated on site by mechanical mud markers. The disadvantages of this indicator device are that there are few indicating scales and large errors. Due to the poor on-site environment, it is difficult for operators to grasp the actual mud volume of each batch of mud guns, which can easily cause the depth of the iron mouth to be unstable and increase the difficulty of opening the iron mouth. It not only wastes gun mud, but also increases the consumption of drill bits and drill rods. In addition, if the mud volume is not well controlled for a long time, it will also make the iron mouth work unstable, the local temperature of the iron mouth will increase, and in severe cases, it will induce furnace steel burn-through accidents.
