Method for aligning iron discharged from blast furnace and molten iron tanks below blast furnace

Abstract

The invention relates to a method for aligning iron discharged from a blast furnace and molten iron tanks below the blast furnace. In the process of iron discharging of the blast furnace, an overturning funnel and molten iron tank aligning tractors are in interlocking control, the molten iron tank aligning tractors are remotely controlled by a remote controller, and a rotary encoder is arranged on an output shaft of a speed reducer of each molten iron tank aligning tractor and connected with a tractor aligning control system; during aligning of the molten iron tanks, moving distance of the molten iron tank aligning tractors is calculated according to rotation turns of wheels, and current tank position and tank number information is updated automatically, transmitted into a blast furnace iron discharging control chamber and displayed on an operating panel of the tractor aligning control system. The molten iron tank aligning tractors are adopted to replace an internal combustion locomotive to complete aligning work of the molten iron tanks below the blast furnace, remote aligning is completed through remote control, the molten iron aligning tractors can be controlled by one remote controller, moving of the molten iron tank aligning tractors in the process of iron discharging due to misoperation can be prevented, and equipment and human safety during iron discharging is ensured.

Description

technical field [0001] The invention relates to the technical field of blast furnace tapping, in particular to a method for aligning blast furnace tapping and molten iron tanks under the furnace. Background technique [0002] At present, domestic ironmaking furnaces are generally smelted in blast furnaces. The molten iron flowing out of the taphole is loaded into the molten iron tank under the furnace by a manually operated overturning funnel, and then removed by a tractor for the molten iron tank. In the process of manually operating the flip hopper to load the molten iron flowing out of the taphole into the molten iron tank under the furnace, the operator communicates with the driver of the tractor of the molten iron tank under the furnace through wireless communication, but in actual work, often due to cooperation Improper operation errors occur, and the hot metal tank tractor moves during the molten iron filling process, resulting in molten iron splashing on the locomoti...

AI Technical Summary

Problems solved by technology

When the molten iron tank is not connected with a diesel locomotive, iron shoes must be placed to prevent the car from slipping, and the iron shoes must be removed during traction, and the placement and removal of the iron shoes must be done manually, so molten iron splashes often cause injury accidents

At the same time, according to the blast furnace tapping process, every time the blast furnace taps molten iron, the alignment of the molten iron tank will be completed in a relatively short period of time, and the rest of the time the combustion engine locomotives are in an idling waiting state to ensure mobility, resulting in a great waste of equipment resources and energy waste
