In order to ensure consistent argon flow in the stopper gas channel and improve argon bubble performance in the slab casting mould,two patented new technologies CSC(Clean Stream Cartridge) and SHP(Slot Hole Plug) were applied in the argon purging stopper designs.The novel stopper designs can maintain a stable back pressure and argon flow in the argon line during long sequence casting,eliminate pressure increasing at the start of the casting,even distribute gas bubbles in the mould leading to improved mould flux melting and lubrication,reduce mould level fluctuation and so on.  相似文献

Monolithic stoppers play a very important role in continuous casting( short for CC). Sometimes,the stopper slag line is seriously eroded and broken,CC has to pause. The research shows that there are three main reasons which bring severe erosion of monolithic stopper slag line. Firstly,much Fe_2O_3 and MnO in slag react with carbon( C) in the stopper,C is gradually eroded and erosion resistance of the stopper greatly weakens. Secondly,F increase in tundish covering flux will quicken erosion of the stopper slag line. Thirdly, High LOI of tundish covering flux also makes erosion of the stopper slag line speed up. On one hand,CaCO_3 in tundish covering flux decomposes and brings CO_2; on the other hand,minerals with water in tundish covering flux decompose at high temperatures and bring water vapor.Then CO_2 and water vapor react with C in the stopper,C is gradually eroded,aggravating the erosion.  相似文献

Conclusions The use in large ladles of stoppers with diameters of 205 mm, with a porosity of 17–20%, and stopper tubes with a porosity of 20–24% ensures normal operation of the stopper during the whole of the casting cycle.The dimensions of the socket brick GK-8 for the bigger stopper do not have to be altered.According to the experience of ChMZ and NTMK (Nizhne-Tagil'sk Metallurgical Combine) the temperature of initial deformation of stoppers without injury to their resistance can be reduced to 1320°C.The desirability of determining this property for stoppers should be established by the refractory institutes.Existing GOST 5500-50 was not fixed for the widely introduced semidry pressing of stopper equipment and changes in the technology of steel-casting.It is necessary to accelerate the incorporation of resolutions made at the All-Union Conference of Refractory workers in 1960 on re-examination of GOST 5500-50.  相似文献

Conclusions Among the principal reasons for partial or substantial leaking of the metal stream are the following: burning away of the stopper, breaking off of the spherical part of the head, wear and tear of the head and sleeve bricks and opening up of the seams through deformation of the rod.The stoppers burn away on account of a great deal of wear and tear in the pipes, erosion of the seams, formation of cracks in the pipes and head and deformation of the stopper on account of the rod becoming too hot.The amount of slag in the ladle is one of the main factors for corrosion wear in stopper pipes. The aggressive action in the slag increases as the temperature of the metal and casting time are increased.Breaking off of the spherical part of the head during the first stopper opening due to the formation of skull between the stopper saddle and head can be avoided by using a graphite filling.Insulation of the stopper rod reduces the temperature during casting by 150–300°. The use of good quality mortar in assembling stoppers reduces the erosion of seams, while the use of a high-alumina putty prevents wear in the pipes.  相似文献

Conclusions Fireclay stopper tubes made by semidry pressing and fired at 800–900° C are suitable for service in steel casting ladles in the open-hearth departments of NTMK. Compared with ordinary low-fired stopper tubes they are more spalling resistant and less thermal conducting.The use of low-fired stopper tubes is economical owing to the reduction in loss and fuel consumption in firing.Translated from Ogneupory, No. 5, pp. 8–10, May 1967.  相似文献
