The invention aims to provide a method for efficiently and accurately installing double-roller ultrathin strip continuous casting machine equipment.
In order to achieve the above object, the present invention is realized by:
an installation method of an ultrathin strip casting roller is characterized by comprising the following steps: comprises the steps of
Step 1, assembling a casting roller frame off line;
step 1.1, arranging a temporary support to integrally mount two casting roll racks by using connecting beams, and accurately adjusting the positions of a track and a casting roll locking cylinder between the racks;
step 1.2, the top frame of the casting roll rack is arranged on the assembled rack, so that the overall strength of the rack can be improved, the adjustment precision can be improved, and the rack cannot deform during hoisting;
step 1.3, respectively installing a cooling water pipe device on the transmission side and the operation side of a rack, and hoisting the cooling water pipe device in place together with a rack;
step 2, integrally assembling cast roll accessories; and (3) installing rotary joints at two ends of the casting roll, wherein the rotary joints are connected in a ferrule type quick joint mode. An upper coupling device is arranged on the transmission side of the casting roll, and the casting roll adopts a tooth-inserted coupling;
step 3, quickly filling the casting rolls;
step 3.1, installing the roller conveying track on the operation side of the frame, installing the roller conveying trolley on the roller conveying track, and placing the two sets of assembled casting rollers on the roller conveying trolley to push the two sets of assembled casting rollers into the frame;
3.2, arranging positioning pins on two sides of the frame, lifting the roller trolley to be transported after the roller trolley is in place, and installing the roller trolley into a positioning pin hole at the bottom of the roller trolley, so that the roller trolley cannot move front and back;
step 4, accurately positioning and firmly locking the casting roller; and a thin jack is arranged between the rack and the roller conveying trolley, and the casting roller is lifted to the proper position and then fixed by using a casting roller locking cylinder.
Aiming at the problems of low online piece-by-piece installation precision and low construction efficiency of more casting roll frame components, the invention adopts an offline assembly integral installation method to improve the installation precision and accelerate the installation progress. Because the casting roller is of a hollow circulating water cooling structure, and the two ends of the casting roller are provided with rotary joints connected with cooling water, the casting roller is assembled on the casting roller in advance by adopting an integral assembly method, so that the online assembly link is reduced, and the installation efficiency is improved. Because the integrally assembled casting roll has larger volume and is inconvenient to install, the assembled casting roll is placed on a roll conveying trolley and is filled into the frame by adopting a roll conveying trolley structure; in order to realize the accurate positioning of the casting rolls, the roll conveying trolley is locked by positioning pins, the roll conveying trolley is jacked by a thin jack, and after the casting rolls reach the installation positions, the casting roll locking hydraulic cylinders are started to fix the casting rolls.
In conclusion, the method for installing the casting roll equipment is beneficial to improving the construction efficiency and has the characteristic of high assembly precision.
