Spraying system for quenching equipment

Abstract

The invention belongs to the technical field of metal processing, and specifically relates to a spray system for quenching equipment, including a cooling water pipeline, a water supply pump, a spray rod and a nozzle, and the spray rods are divided into two rows and installed in the quenching equipment respectively On the upper and lower sides of the roller, each row of spray bars is arranged in parallel with the roller, and the nozzles are vertically installed on the spray bars, and the nozzles are conical flat nozzle nozzles, and the spraying The mouth is elongated, and each spray bar is equipped with a plurality of flat nozzle nozzles arranged in parallel, and the angle between the flat nozzle spray heads and the spray bar is 15°. The spraying system can be used to realize the online roller bottom type aluminum alloy plate quenching and quenching process, reduce energy consumption and improve the solid solution performance of the plate. The design of the conical flat nozzle nozzle and the adjustment of each row of nozzles at an angle of 15° during installation can prevent the fan-shaped surfaces of adjacent nozzles from colliding with each other when spraying, ensuring the cooling effect.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a spray system for quenching equipment. Background technique [0002] Quenching is a metal heat treatment process in which a metal workpiece is heated to an appropriate temperature and maintained for a period of time, and then immersed in a quenching medium for rapid cooling. Commonly used quenching media include quenching liquid, brine, water, mineral oil, air, etc. The purpose of quenching is to transform supercooled austenite into martensite or bainite to obtain martensite or bainite structure. The combination of quenching and tempering at different temperatures can greatly improve the strength, toughness and fatigue strength of the metal, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different use requirements. [0003] The quenching of traditional aluminum alloy medium and thick plates is no...

Problems solved by technology

The traditional roller hearth quenching that is more commonly used in the existing technology needs to wait for the plate to cool down after rolling, and then go offline into the heating zone of the roller hearth furnace for secondary heating to 500-530 degrees, and then quickly enter the water-cooled strong quenching zone to achieve the effect of solid melting , requires secondary heating, resulting in waste of energy consumption, which not only greatly increases the cost of quenching, but also makes it difficult to guarantee the quenching and solid-solution properties of the product
