Abstract

The invention relates to a horizontal roller hearth furnace for heat treatment of aluminum plates. The horizontal roller hearth furnace comprises a charging platform, a furnace body and a discharging platform which are arranged sequentially, wherein the charging platform comprises a charging roller table; the charging roller table is extended into the furnace body; the furnace body comprises a heating section and a cooling section; conveying roller tables are arranged in the heating section and the cooling section; the input ends of the conveying roller tables are connected with the charging roller table; the heat section is provided with a plurality of heating areas which are connected sequentially in a horizontal direction; wind nozzle systems for jetting heating air flow are arranged on the upper side and the lower side of each heating area respectively; nozzle systems for spraying cooling water are arranged on the upper side and the lower side of the cooling section respectively; the discharging platform comprises a discharging roller table; and the discharging roller table is connected with the output ends of the conveying roller tables. According to the horizontal roller hearth furnace, the aluminum plates can be subjected to solid solution heat treatment, recrystallized and aged; quick heating and cooling can be realized, and the optimal mechanical properties can be reached after products are subjected to heat treatment; and an induction type furnace charge control system can realize continuous operation of the whole heat treatment process, and manual maintenance is not required.

Description

technical field [0001] The invention relates to the field of industrial annealing, in particular to a horizontal roller hearth furnace for heat treatment of aluminum plates. Background technique [0002] The roller hearth furnace is a kind of heat treatment furnace commonly used in metallurgical factories. The workpiece is transported by the roller table in the furnace, and the furnace rollers are installed at certain distances along the length of the furnace. The roller hearth furnace is widely used because the materials are heated on both sides and the heating is fast and uniform. Normalizing, annealing, quenching, tempering and other heat treatment processes. [0003] Horizontal roller hearth furnaces for aluminum sheets are mainly used for solution heat treatment, recrystallization treatment and aging treatment. strength. In existing roller hearth furnaces, the friction between the conveying roller and the sheet often causes damage to the surface of the sheet, or the a...
