Abstract

An improved hot continuous rolling coil wrapper roll belongs to facilities of coilers, and comprises a roll body, and is characterized in that two ends of the roll body are frustum-shaped. The length b of the roll body is 2300 mm, the length of the middle part a of the roll body is 1700 mm; the length of each of the two frustum-shaped ends of the roll body is 300 mm; and the height of the tapered roll body in the radial direction is 1.5 mm. Through the use of the improved hot continuous rolling coil wrapper roll, during the producing process of an extra-thin hot rolled strip containing carbon steel with the thickness of below 2 mm and stainless steel with the thickness of below 3 mm, inward loose rolling and telescoped rolling of the coiler are avoided, meanwhile, since the wrapper roll and a drum are not in hard collision, the safety of equipment is protected, the service lives of the drum and the wrapper roll are prolonged, the serious equipment accident is avoided, and the rolling quality is improved.

Description

Improved hot continuous rolling coiling machine helps winding up roller

technical field.

The utility model belongs to the facility of coiling machine, is specifically related to hot continuous rolling coiling machine and helps winding up roller.

Background technology

Fig. 1 is the structure chart that existing hot continuous rolling coiling machine helps winding up roller.

Along with the exploitation of hot continuous rolling factory new product, particularly below the carbon steel 2mm, in the production process of the thin hot-strip of spy below the stainless steel 3mm, loose winding, turriform were rolled up in coiling machine often took place, even caused steel scrap because of twining failure.Trace it to its cause is to set gap=deviator+belt steel thickness * coefficient because of coil wrapper roll; Also be that rolled band steel is thin more, help winding up roller and reel gap more little, as because of the gap actual value less than setting value; Help winding up roller and reel hard collision can occur; Not only possibly cause the bad even steel scrap of scroll, also can cause coiling machine precision forfeiture, even help pernicious equipment breakdown such as winding up roller bearing fragmentation.

Summary of the invention

In order to produce below the carbon steel 2mm, in the production process of special thin hot-strip, avoid loose winding in the coiling machine generation, turriform volume below the stainless steel 3mm, the utility model provides improved hot continuous rolling coiling machine to help winding up roller.

The utility model comprises roll body, and the two ends that it is characterized in that roll body are taper type.

The length b of described roll body is 2300mm, and wherein the length of a is 1700 mm, and the two ends 300mm of roll body is a taper type, and its tapering radial direction height h is 1.5mm.

The use of the utility model is being produced below the carbon steel 2mm, in the production process of the thin hot-strip of spy below the stainless steel 3mm; Avoid coiling machine that interior loose winding, turriform volume take place; Simultaneously, protected device security, prolonged reel and helped winding up roller service life because of helping winding up roller and reel the phenomenon of hard collision can not occur; Avoid taking place pernicious equipment breakdown, improve scroll simultaneously.
