Abstract

The invention discloses pressure testing equipment of a cooling medium of a secondary cooling area for continuous casting and a using method thereof, and belongs to the technical field of pressure testing. The pressure testing equipment comprises a transverse moving mechanism, a longitudinal moving mechanism and a controlling mechanism. The transverse moving mechanism comprises an electrically controlled rail, a position sensor contact point, a sliding base, a pressure transmitter and the like. The transverse mechanism is used for moving the pressure testing equipment transversely. The longitudinal moving mechanism comprises a carrier board, a mobile support and a roller table. The longitudinal moving mechanism is used for moving the pressure testing equipment longitudinally. The controlling mechanism comprises a computer and a display. The using method of the pressure testing equipment includes following steps: firstly, moving the pressure transmitter transversely to finish the pressure field testing of spray nozzles in the first row; secondly, moving the pressure transmitter longitudinally to spray nozzles in next row to finish the pressure field testing of the spray nozzles in the next row; repeating the steps above to finish dynamic pressure testing of all spray nozzles. The pressure testing equipment of the cooling medium of the secondary cooling area for continuous casting is high in accuracy, simple in structure, easy to produce and low in manufacturing cost.

Description

technical field [0001] The invention relates to a pressure testing device, more particularly, to a cooling medium pressure testing device in the secondary cooling zone of continuous casting and a method of using the same, which are mainly used for testing the spray pressure of cooling water mist in the secondary cooling zone of continuous casting in iron and steel plants, It belongs to the technical field of stress testing. Background technique [0002] Continuous casting secondary cooling technology is one of the most critical technologies in continuous casting production. The purpose of secondary cooling is to make the continuous casting billet leave the mold and receive continuous cooling until it is completely solidified. Machine output and billet quality are closely related. In industrial production, once the continuous casting billet has quality problems caused by uneven cooling, the operator can only check the quality of the nozzles one by one under the working condi...
