The characteristics of high speed wire rod rolling mill bearing

The characteristics of high speed wire rod rolling mill bearing: the metallurgical industry in our country by the increasing demand for construction materials in recent years were introduced from abroad dozens of high speed wire rod production line, the discharging mouth speed ranging from 63 ~ 100 m/s, annual production of mostly in 60 & times; 104 ~ 100报; 104 t. High speed wire rod mill work due to the particularity of, puts forward more strict requirements on with bearings. The characteristics of high speed wire rod rolling mill bearing 1. High solid sex is the most striking features of high speed wire rod production line is high reliable mill have homework. Due to the high speed wire rod production line of the unit output value is high, the requirements in the regulations of the tally cycle, the key element in the history of rolling mill bearing is higher than general rolling mill bearing have strong sex. If because of the shaft bearing present problems will lead to the whole production line production, this is the manufacturer will not tolerate. Thus in high speed wire rod rolling mill bearing, planning, manufacture shall ensure that under the condition of high speed operation in the firm. 2. High speed wire rod rolling mill bearing wear resistance better resistance to wear, can adapt to high speed rotating operation occasion. Example: some high speed wire rod production line, the export of linear velocity of 63 m/s, export of rolling mill roll homework a diameter of 330 mm, the bearing of the operation speed of 3650 r/min, long time operation under high speed, heavy load, the wear resistance of bearing will be a severe test. This request for bearing it is necessary to have the requirements of wear resistance. The characteristics of high speed wire rod rolling mill bearing A. High speed wire rod rolling mill bearing fatigue life long fatigue life. Under normal circumstances, the foreign high speed wire rod rolling mill bearing supply using three years ( For half the time roll components to unloading machine maintenance, renovation, the actual operating time for a year and a half) , so the user requirements of domestic bearing can use at least two years. B。 Impact toughness of high speed wire rod rolling mill bearing better impact toughness is better, especially the roughing mill bearing, the continuous casting billet in the process of rolling into a bar, impact load is very large. High speed wire rod rolling mill bearing, therefore, in the condition of high speed, high impact work breakdown phenomenon should not attack. To sum up, the characteristics of high speed wire rod rolling mill bearing. The previous: the smooth bearing next article: steel structure of common material
