| It has broad application prospects to plate Zn , Al and alloy steel wire that it is hot. Of our country metal products enterprise of trade have thousands of, but numerous heat plate production line of steel wire equip abstandardly, automatic level low, production with artificial to operate for main fact, product quality can not get the due assurance, cause the rejection rate to be high, energy consumption is large, the production cost is high, greater disparity exists with foreign countries. The purpose that the production automation of steel wire controls lies in controlling hotly and plating the production technology course, improve the quality of the steel wire , and control one fetches linear velocity and tension in course, make it keep invariable , so as to ensure the steel wife does not produce drawing and phenomenon with insufficient tension . To these kind of situation, this text has studied hotly and plated the automatic control system of electric system of production line of steel wire.Seeing that it is done by hand that the control precision and stability intensity of the computer control systems are all far higher than far, to improving product quality, lowering costs has prominent meanings, this text put forward machine of IBS-PC adopted and Model C8051F000 small-scale and getting collecting and distributing computer control system hot to plate apparatus go on automation make a change to to have now . Thermal balance analysis indicate key equipment of production line help , plate pool and zinc-plated boiler body have balanced target of ability, it is approximate to use a steps inertia link and a delay link. " two laws " formula is simple , easy to distinguish the model parameter which is accused of the target online. The simulation experimental result of the control system indicates the control precision of this system has reached the designing requirement, this scheme is feasible.The load of the traction motor belongs to constant torque loads. The load of the rolling motor belongs to constant power loads. The rules of the timing of the traction motor and the rolling motor during rolling and reversal are analyzed respectively. The scheme of the synchronous control of constant line... |
