 Briefly describe the role of the bottom blowing of the re-blowing in the process of converter smelting (1) Increase the pre-mixing, accelerate the melting of scrap steel, improve the smelting reaction, and facilitate the formation of early slag; (2) Make the blowing process more balanced, reduce splashing, and improve the metal yield; (3) In the later stage, the C-O reaction can be balanced, the oxygen content in the steel can be reduced, and the ultra-low carbon steel can be blown. http://www.tjxysteel.com/news/role-of-the-bottom-blowing-of-the-re-blowing-535.html

 What is the bottom of the furnace? What is the main reason for the rise in the bottom of the furnace? The so-called bottom rise is the gradual increase of the bottom of the furnace during the smelting process, as if it is on the original lining, and a new layer of refractory material is applied. This is a new problem caused by improper operation of dolomite slag. As the bottom of the furnace increases, the slag moves on the line, threatening the furnace cap and affecting the control of the gun position. Therefore, it must be eliminated during the smelting process. The main reason for the increase is the result of excessive slag. http://www.tjxysteel.com/news/main-reason-for-rise-in-bottom-of-furnace-536.html

 The furnace lining works in the furnace. First, a brittle decarburization reaction occurs on the surface, and a “reaction layer” is formed on the surface. The carbon in the reaction layer has been oxidized, and Fe2O3 and SiO2 in the slag invade the brick to form a low melting point substance with MgO and CaO. The more intrusive Fe2O3 and SiO2, the more the fire resistance and high temperature strength of the furnace lining bricks are degraded, even in the state of steelmaking, it becomes the state of the melting contact membrane, and the mechanical scouring of steel slag and furnace gas cannot be withdrawn, so that the brick and furnace lining will be Crisp down. http://www.tjxysteel.com/news/erosion-mechanism-of-Mg-C-brick-lining-537.html

 The secondary combustion oxygen lance has a single flow path and a double flow path. The use of a secondary combustion lance is also a form of thermal compensation technology. By supplying oxygen, the CO gas discharged from the molten pool is partially burned, and the heat in the furnace is supplemented to secondary combustion. Oxygen is divided into two strands after entering the nozzle from one channel. One stream passes through the main hole channel of the Laval nozzle, and the other enters the auxiliary channel of the straight hole. The oxygen flow entering the main channel of Lavalcon is used for smelting; the oxygen entering the auxiliary flow channel is used for the combustion of CO gas in the furnace, also called the end-type secondary combustion oxygen lance; the body of the gun is still three Layer concentric sleeve. The oxygen of the double-flow secondary combustion lance is supplied to the molten pool through the main oxygen flow path and the auxiliary oxygen flow path...

 The hardness test is to slowly press a hard indenter into the surface of the sample under specified conditions, and then test the depth or size of the indentation to determine the hardness of the material. Hardness test is a simple, rapid and easy-to-implement method in material mechanical property test. The hardness test is non-destructive, and there is an approximate conversion relationship between the material hardness value and the tensile strength value. The hardness value of the material can be converted into the tensile strength value, which has great practical significance. Since the tensile test is inconvenient to test, and the conversion from hardness to strength is convenient, more and more people only test the hardness of the material and less test its strength. The hardness of seamless steel tubes is generally measured by three hardness indicators: Brinell, Rockwell and Vickers. 1. Brinell hardness In the seamless steel tube standard, the Brinell hardness is widely us...

 A lead screw is a slender, flexible workpiece. Because slenderness lacks sufficient rigidity and is easy to bend, bending and internal stress are important issues in lead screw processing. The current whirlwind milling process is still suitable, but it needs to be improved continuously, improve the level of existing equipment, and pay attention to solving the problems of tool quality, sharpening and measuring tools. The following describes the screw processing technology: (1) Precision machining of the outer circle and thread can be divided into multiple processes, and the cutting amount can be gradually reduced, thereby gradually reducing the cutting force and internal stress, reducing the machining error and improving the machining accuracy. (2) After each aging treatment, the center hole should be re-drilled or the center hole should be ground to repair the deformation caused by the aging treatment; and remove the oxide scale, etc., so that the processing has a reliable and acc...
