Abstract

The utility model discloses a multi-line slit rolling device which comprises a rough rolling assembly, a moderate rolling assembly, a fine rolling assembly and cylindrical flat rollers arranged on the rough rolling assembly and the moderate rolling assembly. The utility model allows the rolled pieces to be randomly regulated in shape and size prior to multiline slit rolling, to meet the requirements for multiline slit rolling, increase the yield of multiline slit rolled steels and increase the work efficiency of multiline slit rolling.

Description

The multi wire cutting rolling device

Technical field

The utility model relates to a kind of multi wire cutting rolling device.

Background technology

Domestic and international existing multi wire cutting rolling device is to adopt: roughing is an elongation pass sequence, be generally " box-shaped-ellipse-circle " pass schedule, in roll the pass schedule of employing " ellipse-circle ", multi-thread slitting pass system is adopted in finish rolling, the defective of this milling method is: 1, pass quick abrasion, and low precision, being difficult to provides qualified supplied materials for the special slitting pass of finish rolling, cause heap steel accident rate height, make to produce to be difficult to direct motion; 2, thick, in the groove quick abrasion, cause that to change the groove roll change frequent, make steel rolling effective operation rate have only 50%～60%, general rolling 1 hour slotted eye must be changed.While is adjusted frequently owing to change the increase of groove roll change number of times, causes occurring piling the probability increase of steel accident and quality accident; 3, the shared property of pass is poor, need change the roll and the guide and guard of corresponding pass during rolling products of different specifications, causes roll, guide and guard storage level big, drops into to increase; 4, the roll gap adjusting range of pass is little, makes to adjust difficulty.

The utility model content

The purpose of this utility model is to provide a kind of multi wire cutting rolling device, this device can make rolled piece enter the preceding shape and size of at random adjusting rolled piece fast of multi-thread slitting pass, for multi wire cutting rolling provides qualified supplied materials, satisfy the needs of multi-thread cutting, improve multi-thread cutting steel output, improve multi-thread cutting operating efficiency.

The purpose of this utility model is achieved in that a kind of multi wire cutting rolling device, comprises roughing unit, middle milling train group and mm finishing mill unit, and the roll of being installed on roughing unit and the middle milling train group is cylindric plain-barreled roll.

The utility model has carried out structure optimization to original elongation pass sequence under the situation that does not increase any equipment, make the adjustment of roll simplify, and speeds up, and community improves, and roll change is changed the groove number of times and significantly reduced; Greatly improve the anti-wear performance of roll, guaranteed red size precision of every sortie, guaranteed finished size; Because used roll is plain-barreled roll, the rolled piece section can make up arbitrarily like this, high wide size can be adjusted arbitrarily, the qualified supplied materials of any width can be provided for multi wire cutting rolling, satisfy special pass easily, and it is rolling to realize arbitrarily getting rid of frame the supplied materials demand, reduce the use of milling train, roll, significantly reduce power consumption and roll consumption, adopt the utility model can make the operating rate of milling train bring up to 80%～90% by 50%～60%, rolling output of steel can improve more than 50%.The utility model can make rolled piece enter the preceding shape and size of at random adjusting rolled piece fast of multi-thread slitting pass owing to adopt flat rolling, satisfies the needs of multi-thread cutting, improves multi-thread cutting steel output, improves multi-thread cutting operating efficiency.Simultaneously, the utility model Roller Machining is simple, and the turning amount is few, can reduce the outfit of roller machine tool and cutter, reduces maintenance and rolling cost.Iron scale very easily comes off in the flat rolling process, and iron scale can not be brought to mm finishing mill unit, and finished surface is highly polished, quality of finished product good.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a configuration structure schematic diagram of the present utility model;

Fig. 2 is the rolling deformation of rolled wire schematic diagram of process the utility model.

The specific embodiment

A kind of multi wire cutting rolling device as shown in Figure 1, comprises roughing unit, middle milling train group and mm finishing mill unit, and the roll of being installed on roughing unit and the middle milling train group 1,2 is cylindric plain-barreled roll.As shown in Figure 2, utilize plain-barreled roll 1,2 rolling rolled pieces 5 to form rectangular cross section by unrestricted spread, just can make the supplied materials that enters slitting pass 6 obtain stable section configuration and size by simple adjustment milling train drafts, carry out multi wire cutting rolling thereby be convenient to mm finishing mill unit; The used flat roll mill of the utility model can not have the roll gap adjustment, and the rolled piece section is simple, can not occur being full of defective supplied materials such as causing the ears or side handles of a utensil because of crossing, and can guarantee provides dimensional accuracy qualified and control stable raw material for mm finishing mill unit.Cooperate on finished product roller 3,4 roll surfaces of installing on the mm finishing mill unit suit affixed carbon tungsten roller ring.Because tungsten carbide is not easy to wear, can make cutting hole, the rolling tonnage of finished product hole groove bring up to present 800 tons like this by original 100 tons, change groove roll change number of times and descend, operating rate improves.

Claims

1. a multi wire cutting rolling device comprises roughing unit, middle milling train group and mm finishing mill unit, it is characterized in that: the roll of being installed on roughing unit and the middle milling train group (1,2) is cylindric plain-barreled roll.

2. multi wire cutting rolling device according to claim 1 is characterized in that: cooperate on the finished product roller of installing on the mm finishing mill unit (3, the 4) roll surface suit affixed carbon tungsten roller ring.
