Problems solved by technology

[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, the accuracy of the strike angle of the gap nozzle directly determines the quenched plate shape of the quenched and tempered plate, but in the actual quenching process, the characteristics of water flow make it difficult to effectively measure the angle

Embodiment 1

[0017] This embodiment provides a method for quickly measuring the gap nozzle of a quenching machine, which specifically includes the following steps:

[0018] Step 1: Select 3 square logs with the same thickness of 100mm, and apply red lubricating oil evenly on the surface of the square logs, the length of which is 1000mm, and the thickness is 2mm;

[0019] Step 2: Lift the three square logs smeared with red lubricating oil on the exit roller table of the quenching machine, and place them in the order of left, middle and right. The middle square log is placed on the position of 1 / 2 of the width of the exit roller table of the quenching machine , the square logs at the left and right ends are placed 200mm away from the ends of the left and right sides of the exit roller table of the quenching machine;

[0020] Step 3: Start the roller table of the quenching machine, pour the three square logs back to the position of the quenching machine gap nozzle, and reduce the thickness of...

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...
