specific Embodiment approach 1

[0015] A converter furnace body measuring device, as shown in Figure 1, includes a measuring support rod 1, two tie rods 2, a rotatable measuring rod 3, two variable measuring rods 4, a measuring support rod 1 and a rotatable measuring rod 3 are connected by screws 7, and two pull rods 2 are respectively fixed on the two ends of the rotatable measuring support rod 3. The rotatable measuring rod 3 is a hollow tube with multiple positioning holes 5 at both ends. The outer diameter of the variable measuring rod 4 is smaller than the inner diameter of the rotatable measuring rod 3, and one end is provided with multiple positioning holes 5, which can be fixed The pin 6 is fixed in the tube of the rotatable measuring rod 3.

[0016] The converter body measuring device shown in Figure 1 is used to measure the thickness of the lining in the direction of the trunnion of the converter. The measuring method is to turn the converter to 90 degrees, place the measuring support rod 1 on the cent...

specific Embodiment approach 2

[0017] A converter furnace body measuring device, as shown in Figure 2, includes a measuring rod 1, a variable measuring rod 4, a positioning hole 5, and a fixing pin 6. The measuring rod 1 is a hollow tube, and the outer diameter of the variable measuring rod 4 It is smaller than the inner diameter of the measuring rod 1, and one end is provided with a plurality of positioning holes 5, which are fixed in the tube of the measuring rod 1 by a fixing pin 6.

[0018] The converter body measuring device shown in Figure 2 is used to measure the lining thickness of the converter's large surface. The measuring method is to turn the converter to 90 degrees, place the measuring pole 1 on the center line of the converter, and the variable measuring pole 4 is in full contact with the lining Then, fix the position of the variable measuring rod 4 in the pipe of support rod 1 with the fixing pin 5, measure the vertical length from the end of the support rod 1 to the top of the variable measurin...

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 converter body measuring instrument and a measuring method thereof. Background technique [0002] After the converter is replaced with a new furnace lining, it is often eroded and thinned by the slag in the subsequent production process. The erosion rate of the furnace lining must be grasped at all times, and various technical means are used to reduce the erosion rate of the furnace lining, and extend the service life of the furnace lining, that is, increase the furnace age , To achieve the purpose of reducing production costs, and reduce production safety accidents that occur due to the thinning of the lining of the converter body. Use special furnace body measuring tools to detect the thickness of the furnace body refractory material, understand the corrosion status of the refractory material, and guide the converter body maintenance. [0003...
