Wide-and-thick plate heat treatment production line for double rows or multiple rows of cloth

Abstract

The invention relates to a wide-and-thick plate heat treatment production line for double rows or multiple rows of cloth. The wide-and-thick plate heat treatment production line for the double rows ormultiple rows of cloth is arranged in a heat treatment workshop, and comprises a shot blasting front roller table 1, a shot blasting machine 2, a shot blasting machine output roller table 3, a mark spraying machine 4, a charging roller table 5, a heat treatment furnace 6, a quenching machine 7, a finished product discharging roller table 8, a programmable logic controller (PLC) system 9 and the like. A width measurement device is arranged in front of the shot blasting machine 2. The mark spraying machine 4 is arranged in the rear of the shot blasting machine 2. The heat treatment furnace 6 isarranged between the shot blasting machine 2 and the quenching machine 7. The shot blasting machine output roller table 3 and the charging roller table 5 are further arranged between the heat treatment furnace 6 and the shot blasting machine 2. A steel plate I 22 and a steel plate II 23 are used for measuring the length, measuring the width, measuring the thickness, tracking materials and correcting the position in front of a furnace. The quenching machine 7 adopts a frame structure, and comprises a quenching machine body, an automatic control system and the like. A quenching machine lower frame 17 comprises a quenching machine lower roller 12; and a quenching machine upper frame 14 can slide along a guiding pillar up and down.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and relates to a heat treatment production line for wide and thick steel plates produced by two or more rows of cloth. Background technique [0002] The heat treatment of wide and thick plates involves processes such as normalizing, quenching, tempering, and controlled cooling. Among them, the processes of normalizing, quenching, tempering, and controlled cooling require heating the steel to a certain temperature (generally ≧600°C), and then adopt water cooling or The air cooling method lowers the final cooling temperature of the process at a certain cooling rate to achieve the purpose of improving the internal structure and structure of the metal and improving performance. [0003] The heat treatment of wide and thick plates usually uses a roller hearth heat treatment furnace to complete the heating process, and a quenching machine to complete the quenching and controlled cooling...
