specific Embodiment approach 1

[0015] A device for measuring the thickness of the furnace lining in the direction of the trunnion of the converter, such as figure 1 As shown, it includes a measuring rod 1, two pull rods 2, a rotatable measuring rod 3, and two variable measuring rods 4. The measuring rod 1 is flexibly connected with the rotatable measuring rod 3, and the two pull rods 2 are respectively fixed on The two ends of the rotatable measuring rod 3, the rotatable measuring rod 3 is a hollow tube, the two ends are provided with a plurality of positioning holes 5, the outer diameter of the variable measuring rod 4 is smaller than the inner diameter of the rotatable measuring rod 3, and one end A plurality of positioning holes 5 are provided, which are fixed in the tube of the rotatable measuring pole 3 by fixing pins 6 .

[0016] figure 1 The device shown is used to measure the thickness of the furnace lining in the trunnion direction of the converter. The measurement method is to turn the converter ...

specific Embodiment approach 2

[0017] A converter furnace body measuring instrument, such as figure 2 As shown, including measuring pole 1, variable measuring pole 4, positioning hole 5, fixed pin 6, measuring pole 1 is a hollow tube, the outer diameter of variable measuring pole 4 is smaller than the inner diameter of measuring pole 1, and one end is set There are a plurality of positioning holes 5, which are fixed in the tube of the measuring pole 1 by fixing pins 6.

[0018] figure 2 The converter furnace body measuring device shown is used to measure the thickness of the large-surface lining of the converter. The measurement method is to turn the converter to 90 degrees, place the measuring rod 1 on the center line of the converter, and after the variable measuring rod 4 is in full contact with the furnace lining, Fix the position of the variable measuring rod 4 in the pipe of the support rod 1 with the fixed pin 5, measure the vertical length from the end point of the support rod 1 to the top of the...

Abstract

The invention relates to a converter body survey meter in the converter body maintaining area and its measure method, the converter body survey meter includes measuring fulcrum bar, two fulcrum bar, wheel measuring fulcrum bar, two can change measuring fulcrum bar, which feature is that the measuring fulcrum bar activity connects with the wheel measuring fulcrum bar, the two fulcrum bar separately fixed on the two ends of the wheel measuring fulcrum bar. The measure method is that after the converter body survey meter enter the furnace, pull the fulcrum bar on the specify position to keep the wheel measuring fulcrum bar vertical with the measuring fulcrum bar, using the fixed pin fix the wheel measuring fulcrum bar in the wheel measuring fulcrum bar pipe position after the wheel measuring fulcrum bar completely contact with the furnace lining, measuring the vertical length from the wheel measuring fulcrum bar center to the top of the change measuring bar. The benefit of the invention lies in: the simple making, agility operating, can save the cost of purchase the special purposes measuring instrument, can efficiently reflect the furnace lining erosion condition.

Description

technical field [0001] The invention relates to the field of converter body maintenance, in particular to a device and a measuring method for measuring the thickness of the furnace lining in the trunnion direction of the converter. Background technique [0002] After the converter is replaced with a new lining, it is often thinned by the erosion of slag in the subsequent production process. It is necessary to grasp the erosion speed of the furnace lining at all times, and use various technical means to reduce the erosion speed of the furnace lining and prolong the service life of the furnace lining, that is, to increase the furnace life. , to achieve the purpose of reducing production costs, and reduce the production safety accidents of converter furnace body leakage due to thinning of the furnace lining. Use special furnace body measurement tools to detect the thickness of the refractory material in the furnace body, understand the erosion of the refractory material, and gu...
