Abstract
The utility model discloses a two-roll hot rolling mill, which comprises a rolling mill frame; four rotating shafts are arranged on the rolling mill frame in a line from the top down; rolls are arranged at the rotating shafts at the upper and the lower ends; conveying roll tables are arranged in the rolling direction of the rolls; conveying chains are arranged on the conveying roll tables; and conveying rolls are laid on the conveying chains. When the two-roll hot rolling mill conducts hot rolling, heated metal plate blanks are placed on the conveying roll tables, and under the control of a control stand, the metal plates are driven to enter between the two rolls for rolling; when the two-roll hot rolling mill conducts cold rolling, two working rolls are respectively arranged between the upper and the lower rolls, and then cold rolling can be conducted; two rolls are utilized during hot rolling, and four rolls are utilized during cold rolling; and the roll table conveying method is adopted during hot rolling, and the method of conveying roll table through the chains is adopted during cold rolling; and therefore, the rolling with two totally different procedures can be finished on one rolling mill, the manufacturing cost is further saved, and the purposes of energy conservation and environmental protection are achieved.
Description
Technical field
The utility model belongs to the milling equipment technical field, is specifically related to a kind of two roller hot-rolling mills.
Background technology
The processing of sheet metal mainly based on rolling calendering, rollingly can be divided into hot rolling, cold rolling; The major advantage of hot rolling has the productivity ratio height, and can change the cast sturcture of metal, eliminates the defective of microscopic structure, the crystal grain of fining metal material, thus make metal material tissue closely knit, mechanical property improves and improves.This improvement is mainly reflected in along on the rolling direction or after changing rolling direction, thereby makes metal material reduce anisotropy to a certain extent, the reinforcement material consubstantiality; The bubble that forms during casting and pouring, micro-crack and loose also can seam under high temperature and the effect of hot rolling power.
The milling train that milling train, particularly hot rolling in the existing metallurgical processing equipment used does not generally possess cold rolling function, thus on carrying out also needing in addition in the middle of the rolling process of pressure processing the milling train of the cold rolling usefulness of a cover, so just increased the cost of manufacturing.
Summary of the invention
The purpose of this utility model provides a kind of two roller hot-rolling mills, can carry out hot rolling, and it is cold rolling also can to carry out four rollers, thereby has saved manufacturing cost, has taken into account hot rolling and cold-rolling mill advantage separately simultaneously.
The technical scheme that the utility model adopted is, a kind of two roller hot-rolling mills, comprise mill stand, on the mill stand, be arranged side by side four rotating shafts from top to bottom, the rotating shaft at two ends is provided with roll up and down, rolling direction at roll is provided with the transmission roller-way, transmits roller-way and is provided with transmission chain, is equipped with transfer roller on the transmission chain.
Feature of the present utility model also is,
Roll also is connected with console, power distribution cabinet in turn by control line, and console is connected with the transmission roller-way by control line.
The utility model two roller hot-rolling mills during hot rolling, are placed on the metal slabs after the heating on the transmission roller-way, enter between two rolls by console control drive metallic plate to be rolled.When cold rolling, in the middle of top and bottom rolls, two working rolls are set respectively again, just can carry out cold rolling.Use two rollers during hot rolling; Use four rollers when cold rolling.Use the roller-way conveying type during hot rolling, transmit roller bed type with chain when cold rolling.Thereby on a milling train, can finish the rolling of two complete different operations, thereby save manufacturing cost.Having reached is the purpose of energy-conservation environmental protection again.
Description of drawings
Fig. 1 is the structural representation of the utility model two roller hot-rolling mills.
Among the figure, 1. transmit roller-way, 2. transfer roller, 3. mill stand, 4. roll, 5. rotating shaft, 6. console, 7. power distribution cabinet, 8. transmission chain.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model two roller hot-rolling mills as shown in Figure 1, comprise mill stand 3, on mill stand 3, be arranged side by side four rotating shafts 5 from top to bottom, the rotating shaft 5 at two ends is provided with roll 4 up and down, roll 4 can 5 rotate around the shaft, rolling direction facing to roll 4 is provided with transmission roller-way 1, transmits roller-way 1 and is provided with transmission chain 8, is equipped with transfer roller 2 on the transmission chain 8.Rotating shaft 5 also is connected with console 6, power distribution cabinet 7 in turn by control line, and console 6 also is connected with transmission roller-way 1 by control line.
The use of the utility model two roller hot-rolling mills is, during hot rolling, will treat that rolling metal blank is placed on the transfer roller 2, enters between two rolls 4 and is rolled thereby drive metallic plates by console 6 control transmission chains 8.Power distribution cabinet 7 provides power for console 6.When cold rolling, working roll is placed between the roll 4, is about to working roll and is placed in middle two rotating shafts 5, realize cold rolling work by frictional drive.Thereby on a milling train, can finish two different operations, thereby save manufacturing cost.
The utility model two roller hot-rolling mills can roll out long 2m-6m, wide 0.4m-1m, thick 0.2cm-110cm metallic plate.Dimensional accuracy has improved the operating rate of panel production line in ± 0.03mm-0.2mm scope, reduced the specific yield production cost, has saved the energy and manufacturing cost, has improved the business economic benefit.
