Description

Technical Field

[0001] The utility model relates to the technical field of converter charging, in particular to a deoxidation alloying material charging device. Background Art

[0002] The composition of the steel billet determines the organization and performance of the steel. The level of control over the composition of the steel billet is also an aspect of measuring the process control capability of the steel plant. Accurate control of the elements in the steel can reduce the performance fluctuations of the same batch of products and reduce the risk of using steel. At the same time, based on the accurate control of the alloy elements in the steel, a more reasonable steel grade composition can be formulated to reduce alloy consumption. At present, the appropriate amount of alloy is generally added to the converter through the feeding device.

[0004] Most of the existing converter feeding devices do not have a weighing structure. Before loading the deoxidation alloying materials, the deoxidation alloying materials need to be weighed and proportioned, which is very inconvenient. At the same time, there is no deoxidation alloying material mixing structure, and the deoxidation alloying materials can only be fed into the converter, which may cause the deoxidation alloying materials to accumulate in the converter, affecting the specific gravity of the various components of the molten steel inside the converter and affecting the quality of the molten steel.

[0015] Compared with the prior art, the utility model provides a deoxidation alloying material feeding device, which has the following beneficial effects:

[0016] 1. The utility model is provided with a weighing sensor, the upper part of which is connected to the support column, and the material bin is fixedly installed on the upper end of the support column through a fixing plate and a connecting frame. The total weight of the material bin, the fixing plate, the connecting frame and the support column will be monitored by the weighing sensor.
