Method for rapidly measuring quenching machine slot nozzles

Abstract

The invention discloses a method for rapidly measuring quenching machine slot nozzles. The method comprises steps that (1), three square timbers with the consistent thickness are selected, and red lubricating oil is uniformly coated on surfaces of the square timbers; (2), the three square timers are displaced on an outlet roller way of a quenching machine and are arranged at the assigned positionfrom left to right; (3) the roller way of the quenching machine is started, the three square timbers are poured back to the position of the slot nozzle of the quenching machine, distances between quenching machine slots and the square timbers are reduced, the upper and lower slot nozzles are started up and down, and the water supply pressure, the valve opening degree and the continuous water supply time are guaranteed; (4), the roller way of the quenching machine is lifted to 600mm, and the three square timbers are taken out of the quenching machine and are lifted down from the roller way; and(5), an included angle formed by surfaces of the square timbers after water washing is measured through a steel plate ruler, if the tip portion of the included angle is at 1 / 2 of the thickness direction and errors are in the assigned range, requirements are satisfied, if not, the slot nozzle angle is adjusted. The method is advantaged in that a problem of warping of a quenching plate can be completely solved.

Description

technical field [0001] The invention relates to a method for quickly measuring the gap nozzle of a quenching machine. Background technique [0002] The quenching plate shape control of the quenching and tempering plate quenching process is mainly guaranteed by the precision of the quenching machine, and the quenching machine is composed of a high-pressure section and a low-pressure section, of which the high-pressure section is divided into a gap nozzle and a high-density nozzle, and the gap nozzle first contacts the steel plate And the water volume is the largest, and the accuracy of the strike angle of the gap nozzle directly determines the quenched plate shape of the quenched and tempered plate. However, in the actual quenching process, it is difficult to effectively measure the angle due to the characteristics of water flow. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for quickly measuring the ga...
