Example Embodiment

[0043]Example 1 Cooled liquid dispensing type scrap ingredient

[0044]This implementation, for exampleFigure 1 ~ 6As shown, it is a coolant distribution type scrap ingredient, including a cylindrical body 1, a hollow cylindrical structure that is inclined to the upper and lower openings of the converter inverted in the converter. In the present embodiment, the cross section of the cylinder 1 is circular, and the cylinder 1 is disposed in the sidewall of the vaporized cooling flue and communicating with the vaporization cooling and flue. Since the cylindrical 1 is the passage of the scrap into the converter, it has a high wear and impact resistance of the cylinder 1.

[0045]Since the cylindrical body 1 is a hollow structure, the cylindrical body 1 has a cylindrical wall, in order to improve the wear and impact resistance of the cylinder 1, the barrel wall is arranged to become a multilayer structure:figure 2 As shown, the cylinder wall includes a temperature resistant layer 2, a resistan...

[0054]Example 2 Method for fabricating the coolant distribution type scrap ilet

[0055]The present embodiment is a method for producing a coolant dispensing type scrap ingredient opening for the production of a coolant distribution type scrap bubble in Example 1. The method of fabricating the coolant distribution type scrap ingredient in this embodiment includes the following steps:

[0056]Production Cooling Circulating Layer: Take the low temperature cooling layer 4 or the outer wall 15, on the outer wall of the low temperature cooling layer 4 or on the inner wall of the cylinder outer wall 15, the first partition 17 and the second partition 18 are provided in a welded manner. The first separator 17 is provided in a hole in which the circulation tube 19 is welded, and the backhill port 20 is formed in a punched manner. According to the first separator 17 and the second partition 18 in the above step, the first partition plate 17 and the second partition 18 are set. The other end of the...

Abstract

The invention discloses a cooling liquid distribution type scrap steel distribution port, and belongs to the field of metallurgical equipment. A cylinder wall comprises a temperature-resistant layer, an impact-resistant layer, a low-temperature cooling layer and a cooling circulation layer which are sequentially arranged from inside to outside. The invention further discloses a manufacturing method of the cooling liquid distribution type scrap steel distribution port. According to the manufacturing method, the temperature-resistant layer and the cooling circulation layer are taken, the ends of the temperature-resistant layer and the cooling circulation layer are connected and sealed through a lower sealing plate, the ends of the cooling circulation layer are connected and sealed through an upper sealing plate, a cavity is formed, a cooling circulation channel is formed in the cooling circulation layer, and an impact-resistant layer material is poured between the temperature-resistant layer and the low-temperature cooling layer to form the cylinder wall. According to the distribution port, the cooling circulation channel is arranged to cool a cylinder of the distribution port, so that the thermal stress of the cylinder is reduced; the multi-layer arrangement structure is adopted to lower the thermal conductivity and prolong the service life of the cylinder; and the material is simple and easy to obtain, the cost is low, the production efficiency is improved, and the distribution port is suitable for adding all hard materials.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and relates to metallurgical equipment and a manufacturing method thereof, in particular to a coolant distribution type scrap steel batching port and a manufacturing method thereof. Background technique [0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloy as the main raw materials. The steelmaking process is completed in the converter by the physical heat of the molten iron itself and the heat generated by the chemical reaction between the components of the molten iron without the aid of external energy. At present, in order to reduce the amount of molten iron and reduce costs, iron factories will increase the proportion of scrap steel. [0003] In order to add steel scrap more efficiently, in the related art, the steel scrap is added through the batching port at the vaporization cooling flue of the converter. The batching port is a tubular opening connected to the ...
