Standby.Every have independent straightening and drive system, can be with the one of isolated operation group continuous casting installation for casting, referred to as the one of conticaster
Machine.It is referred to as the fluxion of conticaster by the strand radical that the molten steel of a tundish under a steel ladle can be poured into a mould simultaneously.As
Really each stream of a conticaster can isolated operation, this conticaster just be referred to as a few strand casting machine of several machines.General steel plant use
Conticaster all 2 stream 2 machines more than.Each flows down to be required for arranging a roller-way and solidifies, in order to convey crystallizer, the blank.
The blank rollgang currently using all is made up of single free roll, and each free roll includes roll shaft, is enclosed within roll shaft
Roller covers and is enclosed within the bearing at roll shaft two ends.Because roller-way is formed by single free roll is arranged in parallel, and each flows down
Need a roller-way, so the roller of existing roller-way use and number of bearings are all larger.
The continuous casting machine fan-shaped segment roller bed roller-way being to contact at first the high temperature strand that crystallizer condenses out, the blank of roller-way conveying
Temperature very high up to more than 900 DEG C, when the roller set of roller is subject to the high temperature of strand thus when causing roll shaft linear expansion, bearing with
Roll shaft axial stretching, it will directly affect the service life of bearing, and be constantly in due to free roll >=900 DEG C of high temperature under
Work, roller bearing cannot lubricate for a long time, and roller is easy under the influence of being enclosed within long term high temperature produce deformation, leads to conticaster to be fanned
The service life of shape averagely every free roll of section was less than 1 month, so that the spare part usage amount of conticaster remains high always.And
And the roller bearing of the existing use of fan-shaped section is spherical aligning roller bearing, its bearing capacity can not meet the big gauge steel of conveying
The demand of base.
