EICH軸承,EICH軸套,EICH軸承,EICH花鍵 Use of Eich bearings in continuous casting plants. The Eich name has been closely associated with the international steel industry since the 60s owing to the success of the eich roller bearings in continuous casting plants. Eich bearings equipped with the typical spring bushings were installed to meet the demand for a dust-resistant bearing for the strand guide in the upper segments. The Eich bearings were installed both as original equipment and as replacements for the bearing variants used up to that time with solid fixed bearing rings. In 1967 Eich bearings were installed in a GrilloFunke plant as part of its original equipment. Standard roller bearings have a relatively large diameter and therefore require larger roller diameters for the strand guides. In the upper segments of the strand guide, this can lead to a risk of bulging of the elatively thin strand shell. The bearing installed in the upper area has to be sealed in order to withstand the high amount of cooling water sprayed. Even until today, all attempts to use plastic seals have failed due to the high strand temperatures; spray water remains the only cooling element. However, water cooling has the disadvantage that the scale that enters the bearing seat with the cooling water damages the roller body and races of the roller bearing as the rollers rotate. The casting flux required for an optimum casting process forms hydrofluoric acid on contact with water that quickly corrodes the bearings. These conditions put high demands on the bearings: High temperatures cause the material in the bearing seats to expand considerably, which could subsequently lead to blockages in non-spring-bush roller bearings. The largest possible segment width should be used to support the strand, and this requires bearings that can be installed in the roller thereby restricting the space for complex housings with seals. The high strand temperatures and the consequent need for spray water cooling res
