Both sides of the ribs for the customer newly purchased the equipment for cold rolling mill How enables the operator to secure the proper operation of both sides of the ribs cold rolling mill facilities is a major issue that they are concerned about. So Gongyi City Metallurgical Machinery Manufacturing Co., considers multifunction straightening machine production line, for the first time using a cold-rolled ribbed steel bar production line operators, the need to pay attention to the following issues: hazards: High temperature heating equipment, high-temperature logistics, high-speed operation of mechanical equipment, oxygen and other flammable gas and toxic gases, toxic and hazardous chemicals, electrical and hydraulic facilities, energy and lifting equipment, and high temperature operation, noise and smoke impacts. Accident categories: mechanical damage, against objects, lifting injuries, scalding, falls, electrocution and explosions. Cause of the accident: illegal operations and operational errors, technical equipment defects and deficiencies guards, security technology and operational unskilled job adverse environmental conditions, safety regulations do not strict. These are some of the common cold rolling mill production process failures, new and old customers according to their own situation, to avoid these common problems. So as to make both sides of the ribs cold rolling mill equipment last longer multifunction straightening machine equipment, the production process greatly reduce the accident rate. Safety, Hello I'm so Hello everyone! Mill stand by the elastic deformation of the following components: elastic deformation fl (1) of roll system. Elastic four-roll mill roll deformation system consists of three parts: the backup roll bending f11, flexible working roll and backup roll flattening deformation between f12 and work roll and rolled flattened elastic deformation f13 ask that the Department of roll total deformation is: For two-roll mill, no f12 this one. (2) Modification f2 roller bearing. Elastic deformation of the rolling bearing can be calculated multifunction straightening machine parameters and hydrodynamic oil film thickness of liquid friction roller bearing is running with speed variation and change, this film thickness will affect the roll gap change that affects the stiffness of the mill. Through the automatic control system for mill speed compensation to eliminate the effects of the oil film thickness variation of the roll gap. Therefore, multi-straightening machine during mill stiffness calculation, do not consider the impact of changes in the film. Elastic (3) arch deformation f3. St. Paul vertical deformation will roll gap changes that affect precision rolling, it should be considered. Elastic deformation f4 (4) reduction of the system. For electric pressure device, the impact of the elastic deformation of the roll seam includes screws and pressure reduction compression nut and screw thread of bending three parts. (5) bearing elastically deformed f5. (6) the thrust pad, elastic upper plate, lower plate and the top part of the compression load f6. (7) pressure plate aligning contact deformation f7.
