Embodiment 1

[0009] This embodiment is a method for increasing the frequency of the solenoid valve of the quenching machine. The quenching machine is a roller quenching machine, which is suitable for the treatment of the solenoid valve of the quenching machine with long time and stable water volume. The relationship between the frequency increase time and the water consumption per ton of steel is shown in the table:

[0010]

[0011]

[0012] It can be seen from the above table that when the frequency of the quenching machine is increased, the valves are opened one by one, and there is a stabilization time. The current stabilization time exceeds 100S, and the longer the frequency increase time, the more serious the water waste. This embodiment starts with reducing the frequency-up stabilization time, so that the solenoid valve directly reaches the set value. Specifically: when the next steel plate is tapped, click the frequency increase on the quenching machine interface to quickly op...

Abstract

The invention relates to a frequency rising method for a magnetic valve of a quenching machine. According to the method, the interface of the quenching machine is clicked for frequency rising in the tapping process of a next steel plate, the electromagnetic valve is quickly opened to the opening degree under the stable state of a previous steel plate, and then fine adjustment is carried out. The method is mainly applied to the roller type quenching machine with low frequency rising speed, the frequency rising speed can be increased, the problems that the tapping rhythm is limited and the energy consumption is wasted due to the fact that the water yield stabilizing time is long can be solved, and the method is fast, effective and simple. The method has the advantages that the stabilizing time for frequency rising of the quenching machine can be greatly shortened, meanwhile, the tapping rhythm can be accelerated, the benefits can be created, the energy consumption utilization rate can beincreased, and no cost is needed.

Description

technical field [0001] The invention relates to the technical field of quenching machines, in particular to a method for increasing the frequency of a solenoid valve of a quenching machine. Background technique [0002] The steel plate produced by heat treatment tends to be shorter and thinner gradually. In the case of very heavy production tasks, if the production rhythm is not controlled, it is difficult to continuously quench the steel plate while ensuring the performance of the steel plate; during the quenching process, water treatment usually turns on four The pump supplies water continuously, and the water volume of the reservoir reaches a certain height. Only when the interface of the quenching machine can receive the frequency-up signal can the quenching machine be upgraded. This process takes about 8 minutes, which cannot solve the problem of the steel plate entering the furnace without gaps. Contents of the invention [0003] The technical problem to be solved by...
