摘要： PURPOSE:To lower the content of nitrogen by interrupting the supply of an oxidizing gas and an oxidizer temporaily in the region where the carbon concn. in molten steel is above the critical carbon concn. in a decarbonization process and subjecting the molten steel to high vacuum treatment at the time of producing high chromium steels with a vacuum refining furnace. CONSTITUTION:A denitriding and refining method of kexecuting high vacuum treament during oxygen blown refining and decarbonizing at the time of producing high chromium steels such as alloy steels contg. 5-35 Cr, and ferrite or austenite stainless steels. At this time, the supply of an oxidative gas such as oxygen and an oxidizer is interrupted temporarily in the region where the carbon concn. in the molten steel is above the critical carbon concn. and the molten steel is subjected to high vacuum treatment, whereby denitriding reaction is accelerated. In some cases, the molten steel is sujbected to disoxidation treatment by adding a disoxidizer after the temporary interruption of the supply of the oxidative gas and oxidizer, thence it is subjected to the high vacuum treatment.

摘要： PURPOSE:To enable pipe making to be readily done by forming a composite billet compounded with metal of good workability to the core part of the hard-to-work steel material billet and piercing this composite billet. CONSTITUTION:At the steel ingot casting of the hard-to-work metal material to become blank, a metal 3 of good workability is suspended in an ingot case 1, after which the hard-to-work metal steel material 5 is cast to obtain the composite steel ingot. Thence, the composite billet A thereof is formed and this is cut to a suitable length which is then subjected to Mannesmann pipe making. Thence, the thin layer 6 of the metal of good workability left on the inside surface of the resultant pipe is lathed away, to obtain the final product.

摘要： PURPOSE:To safely treat the final billet without generating void by stopping drawing out billet when the molten steel level in the tundish reaches the specified level, charging the tundish with a heat insulating material, and discharging residual molten steel after a specified period of time and before solidification occurs in the feed nozzle. CONSTITUTION:When the tundish 1, mold 3, pinch roller 4 and other components to draw out fillets 5 intermittently draw the final billet, that is, when the molten steel level in the tundish 1 reaches the specified level, pinch rollers 4 stop drawing out billets, and immediately the tundish is charged with a heat insulating material 11. After a period of time defined by the equation t>=3X10 XD where T: time (min) waiting for solidification and D: billet diameter (mm) or minor axis instead if fillet has a flat cross section, and before solidification occurs in the feed nozzle, the cylinder 6 is actuated to open the valve 7 and discharge remaining molten steel in the tundish 1 to the ladle 9. Thereafter, billet 5 is separated from the solidified steel in the tundish 1 by the cylinder device 10.
