Sintered ore FeO content on-line detection device and method with automatic blockage treatment function

Abstract

The invention belongs to the technical field of on-line detection, and particularly relates to a sintered ore FeO content on-line detection device and method with an automatic blockage treatment function. The device is characterized by comprising an electric control system, a feeding and batching scale, a movable framework arranged below a blanking point of the feeding and batching scale, a magnetic induction coil arranged on the movable framework, a moving track which is used for bearing the moving framework, an electric mechanism which is arranged on the moving track, and a material level detection instrument I, a material level detection instrument II and a material flow detection instrument which are arranged on the moving framework. The blocking materials do not need to be cleaned manually on site, the labor environment can be improved, and the labor economic cost can be reduced; the abrasion of the magnetic induction coil and the framework is greatly reduced, the service life of equipment is prolonged, and meanwhile, the maintenance amount and the use and operation cost of the measuring device are reduced; and the FeO content of the sintered ore is accurately measured in real time, and preconditions are provided for improving the quality of the sintered ore and optimizing blast furnace production.

Description

technical field [0001] The invention belongs to the technical field of on-line detection, and in particular relates to an on-line detection device and method for FeO content of sintered ore for automatic processing of blocking materials. Background technique [0002] In steel production, the finished product produced by sintering is called sinter, and sinter is the main raw material for blast furnace ironmaking. Among them, the content of FeO (ferrous oxide) in sinter is one of the quality indicators that ironmaking and sintering attach great importance to. Ironworkers also use the content of FeO in sinter to evaluate the quality of sinter, especially the strength and reduction performance of sinter. An important sign of good or bad. Under certain conditions, the content of FeO in sinter is closely related to its strength, and the content of FeO in sinter also has a great influence on the indirect reduction in the upper and middle parts of the blast furnace.

Problems solved by technology

However, due to the measurement principle, the diameter of the magnetic induction coil cannot be too large, and there are inevitably large pieces of material in the sintered ore, which leads to the biggest problem encountered in the actual use process is material blocking

The result is that the maintenance of the measurement device remains high, and the life of the magnetic induction coil and the skeleton is greatly reduced due to wear and tear, which ultimately affects the use of the entire device.
