Thin Plate Rolling Mill For Industrial Production

Short Description:

Thin plate mill is the rolling (0.3 ~ 4.0) mm × (600 ~ 1000) mm thin plate rolling mill. The standard delivery size of the finished hot-rolled sheet is (0.5 ~ 2.0) × 1000 × 2000mm (thickness × width × length), which is rolled by the corresponding specification slab using a 1200 sheet mill.

Customizable Industrial EquipmentThin plate mill is the rolling (0.3 ~ 4.0) mm × (600 ~ 1000) mm thin plate rolling mill. The standard delivery size of the finished hot-rolled sheet is (0.5 ~ 2.0) × 1000 × 2000mm (thickness × width × length), which is rolled by the corresponding specification slab using a 1200 sheet mill. As a result of high-temperature heating of the slab in the multi-pass rolling. After the large deformation, the edges are not straight, so the four sides are cut. In order to achieve the standard delivery size, the actual rolling to leave an appropriate margin.

Usually the size of the rough board after rolling is about 1040 × 2320mm (width × length), and the effective size of 1000 × 2000mm is cut by the disc unit, the shear rate (shear rate) of the rough board after shearing is: 1000 × 2000 / 1040 × 2320 = 82.89% The loss caused by the cut edge and head reaches 17.11%, which becomes the main bottleneck to improve the rate. The use of the double-size production process can effectively reduce the cutting head loss.

Rolling principle

The basic principle of double-edge rolling is that two sets of finished products are obtained after shearing the double-edge lengths of the rough boards at one time. The advantage is that two sets of plates need to cut two sets of heads and tails, a total of four pieces, while the double-fold rolling system only needs to cut one set of heads and tails, compared with the reduction of one set of heads and tails, thus improving the yield.

The shear rate can be calculated as follows: (1000 × 2000) × 2 / 1040 × 4500 = 85.47%, thus it can be seen that the shear rate can be increased by 2.58 percentage points compared with single-fold rolling by using double-fold rolling.

Heating system

The maximum depression rate should not exceed 35 %, because double-fold rolling than single-fold rolling generally increase 2 to 3 times, resulting in heat dissipation area and heat dissipation time increased, in order to ensure the final rolling temperature, the general opening temperature of the same specification than single-fold rolling increased by 30 to 50 ℃.
