Description
Technical Field
The invention relates to the field of diamond wire bus machining, in particular to a diamond wire bus quenching system and a temperature control method thereof.
Background
Diamond wire is an abbreviation for diamond cut line, also known as diamond cut line or diamond wire. The diamond wire is produced through a plurality of steps by a busbar, wherein the primary step is to pay out the busbar from a wire roller and then carry out one-stage or multi-stage drawing operation, so that the busbar with larger diameter is finally formed into the required diameter through the drawing operation. The current quenching operation of the diamond wire bus is that the steel wire is discharged from a quenching furnace, and the heating temperature is generally about 900 ℃ to obtain complete austenite. If the cooling rate is too high, hard martensite is generally obtained and cannot be drawn at all. After the additive Aqua query 110 is added into water, the AQ110 can increase the viscosity of the water, increase the vaporization temperature of the water, reduce the heat conductivity and form a steam film on the surface of the hot steel wire. The steel wire is not in direct contact with water, and the steel wire exchanges heat with the water in the water through the steam film, so that the steel wire is cooled slowly. The wire cannot be contacted with water at any time and must be surrounded by a vapor film generated by film boiling before the transition is completed. Without the end of the transformation, the wire forms martensite when in contact with water.
Conventional diamond wire busbar quenching has certain defects which are concentrated in: firstly, cooling time in a water tank is difficult to control, cooling treatment of the water tank cannot be carried out according to discharge temperature, the defect that residence time in the water tank is difficult to control often exists, bainite is formed or is caused, boiling is locally generated when the time is too short, the integrity of a vapor film is damaged, meanwhile, the vapor film is broken when the time is too long, and finally the quality of a finished product is influenced; secondly, the traditional cooling after quenching lacks temperature control, after the quenching operation is finished, cooling treatment operation is needed to be carried out on the diamond wire bus in stages, only single AQ single quenching cooling is adopted, the defects are easy to occur, the finished product cannot form austenite, meanwhile, in the cooling process, according to the change of cooling, the transformation from austenite to fine pearlite or sorbite exists, the transformation process is difficult to complete in the AQ single quenching cooling, and if the temperature of the steel wire is excessively high at the stage, the mechanical property of the steel wire can be influenced. Therefore, strict temperature control and time control operation must be implemented for the transformation process, and accurate control is implemented according to the discharging temperature and the material temperature after the AQ single quenching and cooling; again, concentration and the pond liquid level of traditional AQ single quenching cooling in additive can take place to deteriorate when using, along with vapor's evaporation liquid level can reduce, simultaneously the concentration of additive also can change, traditional quenching process lacks the control to this, leads to cooling pond to last behind the use additive and cooling liquid's supply can not keep up, or even give the supply, also can not keep the required effective concentration of cooling, AQ flow can not be too big, otherwise also can lead to the steam membrane to break. To ensure the stability of the vapor film, the surface tension of the vapor-water interface must satisfy a minimum value. This means that the active AQ concentration must be sufficiently high. If the hardness of the water is too high, the concentration of calcium therein will also become high, resulting in carbonization or partial decomposition of the AQ, which in turn results in lower concentrations of active AQ than measured, affecting the quality of the finished product.
Therefore, the diamond wire bus quenching system and the temperature control method thereof have the advantages that the structure is simple, the operation is convenient, the degree of automation is high, the cooling operation can be implemented in sections in the process of quenching the diamond wire, the transformation from austenite to fine pearlite or sorbite is facilitated, the efficient and scientific cooling operation can be implemented on the premise of not affecting the quality of a finished product, the time and the depth of a steel wire in a cooling pool are realized through control, the optimal quenching cooling control is implemented according to the discharging temperature, the concentration and the flow of cooling liquid are always monitored, the optimal cooling effect is kept, and the method is simple and easy to operate, so that the diamond wire bus quenching system and the temperature control method thereof have wide market prospect.
