Heating method of continuous casting slab in soaking pit

Abstract

The invention relates to a heating production method of a continuous casting slab, and particularly relates to a heating production method of a continuous casting slab in a soaking pit. The heating method of a continuous casting slab in a soaking pit of the invention is that: based on the heating characteristics of a continuous casting slab in a pusher-type regenerative furnace and the characteristics of heating steel ingot in a soaking pit, the heating process of a continuous casting slab in a soaking pit comprises the following steps: heating a continuous casting slab with a soaking pit hearth to reach a process-required temperature, performing soaking and heat preservation, and finally performing steel tapping. The invention adopts the above technical scheme, so the soaking pit is utilized effectively; the utilization rate of a rolling mill is effectively increased; without the addition of a new pusher-type regenerative furnace, the normal production of the rolling mill with increased steel rolling productivity can be ensured; the cost of the rolling mill equipment with respect to wind, water, electricity, and gas is reduced; and the energy is saved; idle soaking pits can be utilized effectively, so soaking pits are made the full use of.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, and relates to a continuous casting slab heating production method, in particular to a continuous casting slab heating production method in a soaking pit. Background technique [0002] With the improvement of the rolling rhythm of steel mills, the production capacity of the pusher type regenerative furnace is increasingly unable to meet the rolling needs; the unplanned shutdown of the rolling mill due to insufficient heating time not only affects the normal production of the rolling mill, but also causes wind damage to the rolling mill equipment. , water, electricity, gas costs increase. As for the soaking pit used for heating die casting, due to the excess capacity of die casting, in the case of 6 soaking pits, generally only 4 can meet the needs of die casting production, resulting in waste of resources. Contents of the invention [0003] In view of the above problems, the inventor has...
