| Learned from Tai Chung group, the world's largest bearing oil film bearing was born in the heavy oil film bearing branch. The bearing is the oil film bearing of the wide plate mill produced by Nanjing iron and Steel Co. Ltd., its working diameter is 1670 mm, the working length of the bearing is 1452 mm, the maximum load of the single bearing is 7247 tons, that is, the bearing capacity of one pair of shaft can reach 14494 tons. Related technology personnel said that the bearing is not only the largest load in the world today, but also the world's most in length and diameter. As the heart part of rolling mill, oil film bearing requires large load capacity and high operation accuracy, which plays a vital role in improving the accuracy of steel plate. With the most advanced technology in the world, the product can meet the largest 5.5 meter rolling mill at home and abroad. The product structure, manufacturing precision and product life can reach or exceed the level of the same kind of products abroad. In addition, it has the advantages of simple installation and dismantling process, safe operation and good operation. The price is lower than that of similar products abroad. The successful trial production of the oil film bearing makes a new attempt for the equipment matching of the wide plate mill too heavy. It marks a new lift in the design and manufacturing level of the oil film bearing, breaking the long-term monopoly situation of the foreign company's bearing processing and manufacturing, opening up more for the heavy and even the processing and manufacturing of the oil film bearing in our country. It's a vast market. |
