Main technique function of the bloomer: diameter of the roller is 1150mm1350mm, corporeity of the roller is 3100mm, the work route of travel is 1700mm, the biggest route of travel is 1905mm,the rolling pressure is 3000T, electric motor power is 50002KW, the rotate speed is 03570 rpm, the depressive speed is 142284 mm/sec, the center distance of two toriis is 4140mm, openings degree of the toriis window: the operate profile is1400mm,the transmission profile is 1390mm. The design of this rolling mill include the count of the rolling force,the choice of the electromotor capacitance, the choice of the depressive system, make certain the size of the depressive screm and nut, the choice of the depressive electromotor, the count of the balance means, verify the strength of the rollerthe universal couplingthe machine shelfthe roller bearingsthe wheel gearthe depressive screm and nut ectAnd the choice of the lubricating means,the demand of the contral system,the dependability analyse of the equipment ect. Bloomer adopte the liquid drive morely, mechanisation degree is higher.
