Abstract
The invention relates to a method for monitoring the heat treatment temperature of a power-up steel wire. The method comprises the following steps of: when the steel wire moves and passes through a carrier roller to enter a lead bath groove, performing lead bath treatment, and allowing the steel wire to pass through the carrier roller and enter the lead bath groove to perform the lead bath treatment after the steel wire reaches a preset temperature at the heating stage; at the heating stage, collecting a temperature signal of the movable steel wire by using an infrared thermal imaging system, and transferring the signal to a programmable controller by communication; comparing the temperature of the steel wire with the preset temperature by using the programmable controller, and calculating to obtain direct-current voltage of a direct-current power supply; and regulating the direct-current voltage to regulate energized current on the steel wire to control the heating temperature of the steel wire, so that the steel wire reaches the preset temperature at the heating stage. Due to the adoption of the monitoring method, the heating temperature of the steel wire can be controlled accurately to ensure the heat treatment quality of the steel wire. In addition, the monitoring method is easy and convenient to operate, the yield of machined products is high, and the production efficiency is improved greatly.
Description
Technical field
The invention belongs to steel strand rope and make field, particularly a kind of electric card type Steel Wire Heat Treatment temperature monitoring method.
Background technology
The electric card type Steel Wire Heat Treatment is a kind of method of steel wire being heat-treated with electrically heated mode, and its process is to the perfectly straight stream electrically heated of steel wire, and laggard lead bath quencs.Steel wire is carried out electric card type thermal treatment; The Heating temperature of steel wire will reach more than 900 ℃; Do not stop in the Steel Wire Heat Treatment process to move always; Yet pyritous mobile object like this is carried out relatively difficulty of temperature survey, so a maximum difficult point of electric card type thermal treatment is monitoring and detection to the steel wire heating temperature.The detection of temperature is divided into contact and contactless two kinds; Contact temperature-measuring can reach very high temperature measurement accuracy; But certain request for utilization is arranged, and the steel wire thermometric that thermal treatment is moved for electric card type is also inapplicable, and the electric card type Steel Wire Heat Treatment can only be measured the steel wire heating temperature with contactless.Electric card type Steel Wire Heat Treatment key is the Heating temperature of control steel wire, and the accuracy of its heating and temperature control directly influences the thermal treatment quality of steel wire.Existing temperature controlled method is relatively backward, is the experience that relies on the operator, confirms the Heating temperature of steel wire through the lightness after the visual inspection steel wire heating, and the electrical current of artificially regulating steel wire changes the Heating temperature of steel wire.The therefore existing artificial factor of method is very big, and the operator is different, and sense organ is just different, and the error of steel wire heating temperature is bigger, and is bigger to the thermal treatment quality influence.The past wire temperature adopts two-color thermometer to measure, and artificially regulates steel wire electrical current control Heating temperature then, because people's the sense organ difference and the measuring error of TM self cause the control error of wire temperature bigger.
Summary of the invention
Technical problem to be solved by this invention provide a kind of can application of advanced temperature detection instrument and the automatic control technology realization combining to the electric card type Steel Wire Heat Treatment temperature monitoring method of the accurate control of temperature.
A kind of electric card type Steel Wire Heat Treatment temperature monitoring method after steel wire moves through carrying roller and gets into the lead bath groove and carry out lead bath and handle, gets into the heating phase, and steel wire gets into the lead bath groove through carrying roller again again after the heating phase reaches preset temp carries out lead bath and handle; It is characterized in that: in the heating phase, the temperature signal of steel wire is moved in said infra red thermograph collection, is delivered to programmable logic controller to signal through communication; Programmable logic controller to wire temperature with preestablish temperature and compare, through calculating, provide the volts DS of direct supply; Regulate the size of volts DS; With the electrical current on the adjusting steel wire, thereby the Heating temperature of control steel wire makes steel wire reach preset temp in the heating phase; Programmable logic controller configuration man-machine interface is provided with temperature and shows.
The temperature monitoring method of electric card type Steel Wire Heat Treatment of the present invention with the compared with techniques in past, has precision height, level of automation advantages of higher, has stopped the steel wire heating temperature error problem that causes because of artificial factor.And monitoring method of the present invention is simple, convenient, and the product percent of pass that processes is high, has improved production efficiency greatly.
Description of drawings
Fig. 1 is the monitoring temperature synoptic diagram of electric card type Steel Wire Heat Treatment temperature monitoring method of the present invention;
Embodiment
Along with progress of science and technology; The infra red thermograph that occurred in recent years can satisfy the temperature survey that high temperature moves steel wire; The present invention just is to use infra red thermograph to gather the temperature signal of steel wire, by PLC (programmable logic controller) control steel wire electrical current, wire temperature is controlled automatically.
The crucial equipment of the present invention is infra red thermograph; Though this instrument price comparison is expensive; But can measure the temperature of steel wire in heat treatment process very accurately; Therefore with regard to present technical qualification, adopt infra red thermograph to accomplish the selection that the monitoring to electric card type Steel Wire Heat Treatment Heating temperature is best suited for.
Technical scheme of the present invention is following:
The thermal treatment flow process figure of steel wire as shown in Figure 1 after steel wire moves through carrying roller and gets into the lead bath groove and carry out lead bath and handle, gets into the heating phase; The temperature signal of steel wire is moved in infra red thermograph collection this moment, is delivered to PLC (programmable logic controller) to signal through communication, PLC to wire temperature with preestablish temperature and compare; Through calculating; Provide the volts DS of direct supply, regulate the size of volts DS, to regulate the electrical current on the steel wire; Thereby the Heating temperature of control steel wire makes steel wire reach preset temp in the heating phase.Steel wire gets into the lead bath groove again through carrying roller again and carries out the lead bath processing after the heating phase reaches preset temp.PLC configuration man-machine interface is provided with temperature and shows.
The key of electric card type Steel Wire Heat Treatment is the Heating temperature of control steel wire, and the accuracy of its heating and temperature control directly influences the thermal treatment quality of steel wire.Therefore adopt monitoring method of the present invention can accurately control the Heating temperature of steel wire, thereby guarantee the thermal treatment quality of steel wire.And monitoring method of the present invention is simple, convenient, and the product percent of pass that processes is high, has improved production efficiency greatly.
