Abstract

The invention discloses a fault treatment system of a trolley type spherulitic graphite cast pipe annealing furnace. The trolley type spherulitic graphite cast pipe annealing furnace comprises an electrical control part, a trolley and riding wheels, wherein a PLC (Programmable Logic Controller) is adopted at the electrical control part, the electrical control part is provided with a trolley exiting-in-place limit switch, and the trolley exiting-in-place limit switch is connected with the PLC through a signal circuit. In addition, the invention discloses a treatment method adopted by the treatment system. Due to the adoption of the technical scheme, whether the trolley type spherulitic graphite cast pipe annealing furnace is abnormal in an annealing process is judged, and standby equipment is automatically switched to operate, so that the reliable operation of the equipment is ensured. The standby equipment can be reliably and automatically switched and started, and relevant alarm information can be sent to provide the basis for the following fault judgment.

Description

technical field [0001] The invention belongs to the technical field of production process control in the metallurgical industry, and relates to the production technology of ductile iron pipes. More specifically, the invention relates to a trolley-type ductile iron pipe annealing furnace fault processing system. In addition, the invention also relates to the processing method adopted by the system. Background technique [0002] In the prior art, during the annealing process of the trolley-type annealing furnace, failures of the supporting rollers to stop often occur, causing the annealing tube to be scrapped directly. [0003] After the stall occurs, the problem cannot be found in time. The self-stopping of the supporting wheel causes the annealing tube to be elliptical and scrapped. It is impossible to judge whether it is caused by electrical equipment failure, mechanical failure or operational error. [0004] The equipment is equipped with two 30KW pulley motors controlled...
