Vertical spray quenching apparatus and quenching technique

Abstract

The invention relates to quenching equipment and a quenching process for applying the quenching equipment, in particular to vertical type spray quenching equipment and a quenching process for quenching a large diameter alloy bar. The equipment comprises a heating chamber, a vapor division board, a spray quenching chamber, a feed-and-discharge control system, and a booster pump, wherein the heating chamber, the vapor division board and the spray quenching chamber are arranged vertically in sequence; and the feed-and-discharge control system transports workpieces to the heating chamber and the spray quenching chamber in sequence for heating and quenching treatment. The quenching process comprises the following steps: placing an alloy workpiece at a proper position in the heating chamber; starting a heating program for heating treatment; opening a water inlet and a water outlet of the quenching chamber after heating treatment; then opening a bottom door of the heating chamber, and opening the vapor division board simultaneously; carrying out the quenching treatment after the alloy workpiece enters the proper position in the quenching chamber through the feed opening of the quenching chamber, and closing the vapor division board at the same time; and closing a water inlet valve after finishing the quenching treatment and taking out the alloy workpiece from the top of the heating chamber.

Description

Vertical spray quenching equipment and quenching process Technical field The invention relates to a quenching device and a quenching process using the device, in particular to a vertical spray quenching device and a quenching process suitable for quenching large-diameter alloy bars. Background technique Large-size heat-treatable and strengthened alloy extruded bars have a wide range of applications in the aerospace field. As the diameter size of alloy bars increases, alloy materials encounter hardenability problems. The hardenability of the alloy has an important impact on the performance of the alloy, and also directly affects the safety issues during the aircraft service. How to improve the hardenability of large-diameter alloy bars so as to meet the demand for alloy materials in the aerospace field has become a hot spot of concern among alloy materials workers. Increasing the speed of the water flow impacting the surface of the alloy bar during quenching can break the vap...

Problems solved by technology

Increasing the water flow velocity at which the water flow hits the surface of the alloy rod during quenching can break the vapor film generated during the quenching of the alloy, thereby effectively improving the hardenability of the alloy material, but there is no mandatory requirement for large-diameter alloy rods Report on Spray Quenching Equipment
