SPECIALIZED NUCLEAR-GRADE ZIRCONIUM PLATE ROLLING AND QUENCHING HEAT TREATMENT CONTINUOUS PRODUCTION LINE AND PROCESS THEREFOR

摘要

Disclosed are a specialized nuclear-grade zirconium plate rolling and quenching heat treatment continuous production line and a process therefor. The production line comprises a rolling system (A) and a quenching system (B). The rolling system (A) involves a rolling heating furnace (A1), and a rolling mill (A2), wherein a zirconium plate can move back and forth in a heating area (1b) of the rolling heating furnace; and the quenching system (B) comprises a heating furnace (B1), a rapid quenching device (B2) arranged at an outlet of the heating furnace, and a traversing roller way (B3) arranged at the outlet of the heating furnace and communicating with a conveying roller way, towards the rolling mill, of the rolling heating furnace. By means of the production line and process, on the one hand, the processes of rolling and quenching are directly coupled, so that continuous processing is realized; and on the other hand, through the arrangement of a temperature area of a furnace roller assembly in the heating furnace, the length of the whole furnace body is shortened, the equipment structure is simplified, and the cost and the energy consumption are reduced.
