A Method of Improving the Reliability of Tundish Baking Flame Detector

Abstract

The invention provides a method for improving reliability of a tundish baking flame detector, and belongs to the technical field of steelmaking and continuous casting. The method comprises the following steps: firstly detaching sealing treatment of the flame detector; then manufacturing a fixing block of a position adjusting mechanism of the flame detector and welding the fixing block to the outside of a rotating shaft of a rocker arm; manufacturing the position adjusting mechanism of the flame detector; connecting the position adjusting mechanism of the flame detector to the fixing block of the adjusting mechanism of the flame detector by a position adjusting bolt; mounting the flame detector in a seamless steel tube of the position adjusting mechanism of the flame detector and fixing the flame detector by a locking bolt; and adjusting the position of the position adjusting mechanism of the flame detector by loosening the position adjusting bolt. The method has the advantages that the position and the angle can be adjusted flexibly, namely, the reliability of the flame detector can be improved, the service life is prolonged, and costs of spare parts are reduced.

Description

technical field [0001] The invention belongs to the technical field of steelmaking and continuous casting, and in particular relates to a method for improving the reliability of a tundish baking flame detector. Background technique [0002] The function of the tundish baking device is to bake the tundish, which can increase the temperature of the refractory lining in the tundish, remove the moisture in it, and reduce the temperature drop and heat loss of the molten steel in the tundish. [0003] The tundish roasting device has complete safety protection facilities. The flame detector mainly monitors whether the flame is normal when the ladle roaster is running, and can capture the infrared rays emitted by the burning flame to judge whether the burning is normal. If there is an abnormal flameout, start the automatic ignition system immediately. If it still cannot be ignited within 30 seconds, cut off the gas immediately and send an alarm. [0004] The original design of the ...
