The invention provides a vertical quenching furnace which comprises a liner, a furnace body and a column, wherein the upper end and lower end of the furnace body are respectively welded at the upper end and middle part of the column. The vertical quenching furnace is characterized by also comprising a lifting platform, wherein the lifting platform is positioned at the lower part of the furnace body; cross beams are arranged at the upper and lower ends of the lifting platform; a roller is arranged at the lower part of the cross beam at the lower end; the roller is clamped on a guide rail. When the equipment works, the lifting platform enables the liner to enter the furnace body and prop against the furnace body to guarantee air tightness; when a heating and thermal insulation stage ends, the lifting platform is operated to descend, and an air blower is started so that the liner is quickly cooled and an expected cooling effect is realized and the product performance is not influenced; the vertical quenching furnace has the beneficial effects that the cooling effect after the heating and thermal insulation is accelerated, the reject ratio of the product is reduced, and the space is saved.
Description
technical field [0001] The invention belongs to the technical field of heat treatment processing equipment, and in particular relates to a vertical quenching furnace. Background technique [0002] Quenching is a heat treatment process in which the raw material is heated above the critical temperature, kept for a period of time, and then rapidly cooled at a cooling rate greater than the critical cooling rate. Usually, the solid solution treatment of steel, aluminum alloy, copper alloy, titanium alloy, tempered glass and other materials or the heat treatment process with rapid cooling process is called quenching. [0003] Most of the existing equipment for thermal processing are horizontal equipment, and most of them are horizontal equipment for this quenching process. Due to the need for rapid cooling during the quenching process, the quenching transfer time should not be too long, otherwise the performance of the product will be affected, some unqualified products will be p...
