[0003] Due to abnormal conditions, steelmaking and continuous casting produces slabs with components exceeding the standard, continuous casting slabs of different steel types, water exchange slabs, etc. These slabs cannot be digested and processed because they do not meet the requirements of the original standard. The general treatment method is to cut waste and give Steel mills bring big losses

Embodiment 1
[0024] A method for rolling a checkered plate using an abnormal billet, comprising the following steps:
[0025] (1) Cut the abnormal slab produced by steelmaking to the standard patterned slab size, and the length required for cutting should be greater than 8m (to ensure that the steel is loaded in the walking heating furnace) and less than 9.5m (to ensure that the finished coil diameter is smaller than the maximum coil diameter of the coiler) Design), change the steel type mark, accumulate the abnormal slab quantity, and facilitate the scheduling of checkered plate production in batches.
[0026] (2) The upper roll of the finish rolling stand adopts patterned rolls, and it is required to inquire about the use history of the rolls every time the rolls are selected and engraved with patterns. The roll body must undergo another ultrasonic flaw detection inspection before the roll is grooved, and the pattern to be engraved can only be selected after confirming that the roll surf...

Abstract
The invention discloses a method for rolling a patterned plate by using an abnormal blank. The method comprises the following steps: firstly, cutting an abnormal blank produced by steelmaking into thestandard patterned plate blank size, carrying out heating and rough rolling, using a pattern roller as an upper roller of a finish-rolling final rack, using different tail rack fixed reduction ratesaccording to different thicknesses of a finished patterned plate coil for rolling, using high-pressure air blowing at the laminar cooling tail end, setting a coiling thickness coefficient according tothe pattern height calculated according to the final rack reduction rate, and finally obtaining the finished pattern plate coil. Thus, the abnormal blank of steelmaking can be effectively utilized toroll the finished patterned plate, and cutting waste loss is avoided.
Description
technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a method for rolling a checkered plate by utilizing an abnormal billet. Background technique [0002] The steel plate with a pattern on the surface is called a checkered plate, and the most common one is the lenticular shape in the market. The checkered plate has many advantages such as beautiful appearance, anti-skid, enhanced performance, and steel saving. It is widely used in transportation, construction, decoration, floor around equipment, machinery, shipbuilding and other fields. Generally speaking, the user does not have high requirements on the mechanical properties and mechanical properties of the checkered plate, so the quality of the checkered plate is mainly manifested in the flower formation rate and height of the checkered plate. [0003] Due to abnormal conditions, steelmaking and continuous casting produces slabs with components exceeding the stand...
