Quenching furnace with methanol gasifying device

Abstract

The invention discloses a quenching furnace with a methanol gasifying device, comprising the quenching furnace which is interlay horizontally provided with a mesh belt for conveying workpieces. The quenching furnace is characterized by also comprising the methanol gasifying device; a plurality of pipelines communicated with the quenching furnace are arranged on the top of the quenching furnace; the air inlets of the pipelines are communicated and connected with the methanol gasifying device; in the quenching furnace, fans are arranged beside the air outlets of the pipelines; a main control chamber of the quenching furnace is provided with a CP value display device; and the CP value display device is connected with an oxygen-carbon head. The invention solves the problems of incomplete gasification and decomposition of liquid methanol in the quenching furnace, damage of a furnace body and the workpieces and environment pollution in the prior art and provides the quenching furnace with the methanol gasifying device, thereby enabling the methanol to be gasified and cracked in the methanol gasifying device; and in addition, the invention can well control the flow of gasified methanol, thereby enabling a methanol gas to be uniformly distributed.

Description

technical field [0001] The invention relates to an improved device for a heat treatment process, in particular to a quenching furnace with a methanol gasification device. Background technique [0002] The metal heat treatment process is to heat the metal workpiece to an appropriate temperature and keep it for a period of time, and then immerse it in the quenching medium for rapid cooling. Commonly used quenching media are brine, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, measuring tools and parts that require surface wear resistance (such as gears, rolls, carburized parts, etc.). Through the combination of quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different use requireme...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem of incomplete gasification and decomposition of liquid methanol in the quenching furnace in the prior art, resulting in carbon deposition, damage to the furnace body and workpieces, and environmental pollution, the present invention provides a quenching furnace with a methanol gasification device , so that methanol is gasified and cracked in the methanol gasification device, and it has been completely decomposed in the quenching furnace. At the same time, the flow rate of gasified methanol can be well controlled, so that the methanol gas is evenly distributed
