Abstract

The invention discloses a heat treatment device for a nodular cast iron piston casting, and belongs to the technical field of nodular graphite processing equipment.The heat treatment device comprises a heat treatment device body, a heat isolation plate and an isolation connecting plate. The isolation connecting plate is fixedly installed at the top of the heat treatment device body, the heat isolation plate is fixedly installed on the outer side of the isolation connecting plate, the bottom of the isolation connecting plate is fixedly mounted at the top of the heat treatment device main body, and the bottom of the heat isolation plate is fixedly mounted at the top of the heat treatment device main body. The heat treatment device is ingenious in design, the heat treatment main body, the heat storage plate and the heat anti-diffusion plate are combined, the problem that when an existing heat treatment device is used, the device cannot store internal heat is conveniently solved, and by means of the structure, the heat treatment device can store the internal heat when being used, so that the effect of improving heat preservation of the equipment can be achieved, and heat is prevented from being diffused outwards in the using process.

Description

technical field [0001] The invention relates to a heat treatment device, and relates to the technical field of nodular graphite processing equipment, in particular to a heat treatment device for a ductile iron piston casting. Background technique [0002] Graphite cast iron refers to adding graphite to cast iron, and under certain conditions, the graphite is spherical, which can greatly increase the hardness and strength of cast iron. Cast iron is divided into several grades of gray cast iron according to the tensile strength. Generally, HT200 and HT150 are used. , Below HT100, use gray cast iron. When the tensile strength is above 250, nodular cast iron has better anti-friction properties and is often used in places where wear resistance is required. The production of nodular cast iron in my country started very early. It was successfully developed and put into production in 1950. So far, the annual output of nodular cast iron in my country Reached 2.3 million tons, ranking...
