Problems solved by technology

[0018] 1. The rolling force setting of hot continuous strip steel is only for a single material, and the deformation resistance setting for composite materials cannot be accurately set
[0019] 2. The deviation of the rolling force forecast will lead to the out-of-tolerance of the strip size. Due to the large second flow matching deviation of the rack, the serious deviation will lead to scrap steel in the rack

Abstract

Disclosed is a rolling force prediction method for hot continuous rolling composite material strip steel. Incoming material information is received through a process control machine, and the materialof an incoming material is determined; and a rolling force based on a single plate and a rolling force based on a composite plate are established according to determined material properties of the incoming material, thereby establishing the rolling force prediction method suitable for production process control of multi-layer hot continuous rolling composite material with different materials.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and in particular relates to a rolling force prediction method for hot continuous rolling composite material strip steel. Background technique [0002] like figure 1 As shown, the hot rolling process generally includes heating, rough rolling, finishing rolling, coiling, transportation, finishing and other processes. First, according to the rolling plan, the slabs are loaded into the walking heating furnace 11 in sequence. After the slabs are heated to the target temperature specified by the process, the slabs are drawn out one by one by the steel pumping machine, placed on the roller table in front of the furnace, and then the hot slabs are transported to the rough rolling unit. In the roughing mill, the slab first enters the No. 1 descaling box 12 for descaling. Send into E1, R1 two-roll reversing mills 13 and 14 again, rolling 1-3 passes. Then the slab enters E2, R2 four-high reversin...
