A surface carburizing reaction kettle

Abstract

The invention belongs to the technical field of surface carburization, and particularly relates to a surface carburization reaction still. The surface carburization reaction still comprises a reactionstill, a first rotating disc, a second rotating disc and first springs, wherein the right side wall of the inside of the reaction still is rotatably connected with the second rotating disc; a rotating shaft is driven by a motor; the other side of the first rotating disc is fixedly connected with a first fixed frame; one side of the first fixed frame is fixedly connected with a compression plate;one side of the compression plate is connected with the second rotating disc through three first springs which are equidistantly arranged; cams are symmetrically arranged in the reaction still; one side of each cam is connected with a worm wheel through a fixed shaft; one side of each worm wheel is meshed with a worm rod; an upper sieving plate and a lower sieving plate are successively arranged in the reaction still from top to bottom; the upper sieving plate is in sliding connection with the lower sieving plate; two ends of the lower sieving plate are symmetrically and fixedly connected withconical springs; a spiral groove is formed in the exterior of the second rotating disc; the lower part of the second rotating disc in the reaction still is fixedly connected with a second fixed frame; a gas inlet is formed in the bottom of the reaction still; a controller is arranged at the exterior of the reaction still.

Description

technical field [0001] The invention belongs to the technical field of surface carburizing, in particular to a surface carburizing reaction kettle. Background technique [0002] Carburizing is a kind of metal surface treatment. Carburizing is mostly low-carbon steel or low-alloy steel. The specific method is to put the workpiece into a single-phase austenitic steel with active carburizing medium and heat it to 900-950 degrees Celsius. After a sufficient time of heat preservation, the activated carbon atoms decomposed in the carburizing medium will infiltrate into the surface layer of the steel part, thereby obtaining high carbon in the surface layer, and the core part still maintains the original composition. When carburizing treatment, a carburizing treatment is required Carbon Reactor. [0003] There is also a surface carburizing reaction kettle in the prior art, such as a Chinese invention with the application number 2015800139854 disclosing a carburizing device, which h...
