AI Technical Summary
In the existing technology, the addition of limestone is inconvenient during the steelmaking process of high-strength geological drill pipe steel, which causes molten steel to adhere to the ladle and affect the steelmaking efficiency.
Design a steelmaking furnace device for high-strength geological drill pipe steel, and set up a pipeline connection between the limestone silo and the ladle station. Control the addition of limestone through valves to ensure that limestone covers the inner wall of the ladle to reduce the adhesion of molten steel.
It effectively reduces the adhesion of molten steel inside the ladle, improving the convenience and efficiency of steelmaking operations.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steelmaking technology, specifically relating to a steelmaking furnace device for high-strength geological drill pipe steel. Background Technology
[0002] In the steelmaking process, limestone mainly serves as a slag-forming material and deoxidizer, helping to remove harmful impurities from the molten steel and adjusting the composition, basicity, and viscosity of the slag.
[0003] For this purpose, a limestone silo is located upstream of the smelting furnace to facilitate the addition of limestone. Utility Model Content
[0004] The technical problem to be solved by this utility model is: how to design a steelmaking furnace device for high-strength geological drill pipe steel that facilitates the addition of limestone to the ladle.
[0005] The specific technical solution of this utility model is as follows:
[0006] A steelmaking furnace apparatus for high-strength geological drill pipe steel includes a steel smelting plant, a ladle station located below the side of the steel smelting plant, a limestone silo located upstream of the steel smelting plant, the limestone silo being connected to the steel smelting plant via a smelting furnace pipeline, one end of the limestone silo being connected to the ladle furnace pipeline, and the other end of the ladle furnace pipeline reaching above the ladle station.
[0007] The smelting furnace pipeline and the ladle furnace pipeline are respectively equipped with a first valve and a second valve.
[0008] Compared with the prior art, the technical effect of this utility model is that it is equipped with a ladle limestone pipeline, which can add limestone to the ladle and reduce the amount of molten steel adhering to the ladle. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation
[0010] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0011] like Figure 1 A steelmaking furnace device for high-strength geological drill pipe steel includes a steel smelting 10, a ladle station 11 located on the lower side of the steel smelting 10, and a limestone silo 20 located upstream of the steel smelting 10.
[0012] The limestone silo 20 is connected to the steel smelting 10 through the smelting furnace pipeline 21. One end of the limestone silo 20 is connected to the ladle furnace pipeline 23, and the other end of the ladle furnace pipeline 23 reaches above the ladle station 11.
[0013] For ease of control, a first valve 22 and a second valve 24 are respectively installed on the smelting furnace pipeline 21 and the ladle furnace pipeline 23.
[0014] like Figure 1 Its working principle is as follows:
[0015] When the molten steel flows out, the ladle reaches the ladle station 11. First, the second valve 24 is opened, a layer of limestone is laid on the inner wall of the ladle, and then the molten steel in the steel smelting 10 flows into the ladle.
[0016] Features of this application:
[0017] After a layer of limestone is laid on the inner wall of the ladle, the limestone prevents some of the molten steel from sticking to the ladle, which helps the molten steel to flow out of the ladle and makes the steelmaking operation more convenient.
[0018] For other details, please refer to the existing technology.
[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
