Embodiment Construction
[0043] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0044] The invention discloses a process method for continuous heat treatment of steel plates with variable specifications, see figure 1 , for a roller quenching machine, the roller quenching machine includes a roller table, and a plurality of high-density nozzles and a plurality of gap nozzles arranged between each roller of the roller table, the method includes: measuring the length, width and thickness of the steel plate to be processed ; When the thickness of the steel plate to be processed is greater than 10mm, calculate the water volume, water pressure and time required for quenching according to the length, width and thickness of the steel plate to be processed; transport the steel plate to be processed to the cooling area where the high-density nozzle is...

The invention relates to the technical field of heat treatment of metal materials, in particular to a method of continuous heat treatment process of a variable-specification steel plate. The method is used for a roller quenching machine, and comprises the following steps of measuring the size of the steel plate; when the thickness is greater than 10 mm, calculating out the water quantity, water pressure and time of quenching, using a roller way to convey the steel plate to an area where a high-density nozzle is located, opening the high-density nozzle, carrying out quenching according to the calculated water quantity, water pressure and time, and delivering the steel plate out of the quenching machine; and when the thickness is less than or equal to 10 mm, calculating out the water quantity and water pressure of quenching, opening a gap nozzle, conveying the steel plate with the roller way to pass through the gap nozzle, and then delivering the steel plate out of the quenching machine. According to the method, the quenching procedure is selectable according to different thickness of the steel plate, and then the steel plate is directly fed into a designated area of the quenching machine to finish quenching, so that the quenching procedures are rapidly selected and switched when the quenching machine is used for processing continuous production of small-batch and multi-specification steel plates, the process conversion / adjustment time is shortened, the production efficiency is improved, and the energy is saved.
Description
technical field [0001] The invention relates to the technical field of heat treatment of metal materials, in particular to a process method for continuous heat treatment of steel plates with variable specifications. Background technique [0002] Roller quenching machine is the main equipment for continuous heat treatment of metal plates and strips in the prior art. It has the characteristics of high automation, high production efficiency, and good performance stability. It is suitable for mass heat treatment production of single-size steel plates. [0003] In modern production, for the continuous production of small batches and multi-specification steel plates, the existing roller quenching machines often need to frequently replace the quenching procedures of the quenching machine, so there is an increase in the proportion of invalid production time such as process conversion / adjustment, which reduces production efficiency and energy consumption. Waste and so on. Contents ...
