Description

Technical Field

Background

At present, the phenomena of dirt, fatigue, benzene and the like exist in the field of manufacturing of graphite electrodes in China, the graphite electrodes belong to smelting steel consumables, the demand is continuously increased, more and more manufacturers start to invest in the processing production of the graphite electrodes, and the following problems exist in the processing production process of the graphite electrodes: firstly, the graphite electrodes need to be connected in series, marshalled and transported in the processing and production process of the graphite electrodes, but at present, the graphite electrodes are separately operated, and then are uniformly hoisted and roasted after being uniformly connected in series and marshalled, so that the processing and production efficiency of the graphite electrodes is low; secondly, in the operation of serially connecting and grouping the graphite electrodes, most manufacturers still adopt the original manual operation at present, and particularly, each furnace needs to be subjected to serial connection and transfer for twenty times for the small-diameter graphite electrodes, which is time-consuming, labor-consuming and extremely low in efficiency; thirdly, a bridge crane is mostly adopted for transferring during transferring of the graphite electrode, however, lifting of a lifting appliance of the bridge crane is mostly controlled by an electric hoist steel wire rope, so that during the lifting and throwing processes of the graphite carbon rod, the lifting appliance of the crane can swing due to inertia, the swinging of the lifting appliance not only easily causes the graphite carbon rod to fall off from the lifting appliance to cause safety accidents, but also influences the accurate throwing of the carbon rod, so that when the carbon rod is thrown into a roasting furnace, workers often need to manually regulate and control, and the roasting processing efficiency of the graphite electrode is seriously influenced; fourthly, the existing crane lifting appliance is mostly provided with lifting hooks, workers need to firstly use ropes to bind the graphite electrode carbon rods, and then hang the lifting hooks on the ropes for lifting, and the operation mode is complex in process, time-consuming and labor-consuming, and the graphite electrode carbon rods often fall off in the lifting process, so that great potential safety hazards exist; fifthly, in the roasting processing process of the graphite carbon rod, the graphite carbon rod is required to be hoisted, and the roasting furnace heat-insulating cover is also required to be hoisted, however, if a lifting appliance of the bridge crane is convenient to grab a grapple of the graphite carbon rod, the roasting furnace heat-insulating cover cannot be effectively hoisted, and needs to be hoisted after being bound and fixed by using a steel wire rope, the roasting furnace heat-insulating cover can cross over from the upper part of an operator or equipment in the hoisting process, and if the roasting furnace heat-insulating cover falls off in the hoisting process, a great safety accident is easily caused; therefore, an integrated operation device capable of realizing the processing and production of the graphite electrode is urgently needed.
