Abstract
The invention relates to the technical field of carburization, in particular to a double-cavity carburizing pot. The double-cavity carburizing pot comprises a pot body, a crush resisting layer, a heating chamber, an intermediate separation layer, a cooling chamber and an external temperature control device. The double-cavity carburizing pot is characterized in that the crush resisting layer is arranged on the periphery of the interior of the pot body, the pot body is divided into the heating chamber and the cooling chamber by the intermediate separation layer, and the external temperature control device is located on the right portion of the pot body. The heating chamber is composed of a high-temperature-resistant heat-insulation layer and a bottom heating device. A condenser and an exhaust pipeline are arranged in the cooling chamber, and the cooling chamber is connected with the external temperature control device. The double-cavity carburizing pot has the advantage that heating and cooling are integrated. Equipment is condensed rapidly through the condenser after carburization; in addition, the pressure applied to the pot body when the carburizing pot works can be effectively lowered through the crush resisting layer, the equipment is effectively protected, and the service life of the equipment is prolonged.
Description
Technical field
the present invention relates to a kind of carburizing tech field, especially relate to a kind of dual cavity packing pot.
Background technology
carburizing is the process of instigating carbon atom to penetrate into steel upper layer.Also be the upper layer making the workpiece of soft steel have high carbon steel, then through quenching and low-temperaturetempering, make the upper layer of workpiece have high rigidity and wear resistance, and the centre portions of workpiece still remain toughness and the plasticity of soft steel.The chemical composition of carburizing Hou ﹐ steel piece surface can close to high carbon steel.Also will through Cui Huo ﹐ to obtain the high wear resistance of high Biao face Ying Du ﹑ and Pi labor Qiang Du ﹐ and Qiang Ren ﹐ after keeping heart portion to have soft steel to quench makes workpiece can withstand shocks load after workpiece carbonization.Carburization process is widely used in the Ji tool Ling Jian ﹐ of Fei Ji ﹑ automobile and tractor etc. as Chi Lun ﹑ Zhou ﹑ camshaft etc.
gas cementation, Gu body Shen Tan ﹑ Ye body Shen Tan ﹑ and carbonitriding (cyaniding) can be divided into by different ﹐ carburizing of carbon containing medium.Gas cementation is loaded by workpiece in airtight cementing furnace, pass into gas penetration enhancer (methane, ethane etc.) or liquid penetration enhancer (kerosene or benzene, alcohol, acetone etc.), at high temperature decomposite active atoms of carbon, infiltrate workpiece surface, to obtain a kind of carburizing operating procedure of high carbon surface layer; Solid carburizing is contained in airtight case hardening box by workpiece together with solid carburizer (charcoal adds promotor composition), case is put into process furnace and is heated to carburizing temperature, and held for some time, make active atoms of carbon ooze a kind of method for carburizing the earliest of people's workpiece surface; Liquid carburizing utilizes liquid medium to carry out carburizing, and conventional liquid carburizing medium has: silicon carbide, " 603 " carburizing agent etc.; Carbonitriding (cyaniding) is divided into again gas carbonitriding, liquid carbonitriding, solid carbonitriding.
in recent years, there is high concentration carburizing process, in complete austenitic area, (temperature is at 900 ~ 950 DEG C with traditional technology, carburizing rear surface carbon mass fraction is 0.85% ~ 1.05%) carry out carburizing difference, it carries out under the inhomogenous austenite state between Ac1 ~ Accm, and its layer surface carbon concentration can up to 2% ~ 4%.Its result can obtain fine particle carbide evenly, the infiltration layer of Dispersed precipitate.Its carburizing temperature is down to 800 DEG C ~ 860 DEG C temperature ranges, can realize direct quenching after general steel carburizing; The carbide of the Dispersed precipitate of very high quantity (20% ~ 50%) is contained due to high-concentration carburized layer, therefore demonstrate wear resistance, the solidity to corrosion more excellent than common carburizing, higher contact and bending fatigue strength, higher impact toughness, lower fragility and good temper resistance.This technique also has suitability extensively, to equipment without advantages such as particular requirements, has higher economic benefit and practical value, obtains competitively research and development at home and abroad in recent years.
due to the high temperature produced in cementation process, after work is completed, the cooling of equipment defines certain difficulty, and the pressure produced in cementation process has a certain impact to equipment, causes the inconvenience in production.
Summary of the invention
the object of the present invention is to provide a kind of dual cavity packing pot, the impact caused with the cooling and pressure that overcome existing high temperature.
the object of the present invention is achieved like this.A kind of dual cavity packing pot, comprise tank body, resistance to compression layer, heating chamber, middle insulating course, cooling room, it is characterized in that: tank interior surrounding is provided with resistance to compression layer, tank body is divided into heating chamber and cooling room by middle insulating course, and outside temperature control unit is positioned at the right part of tank body.
described heating chamber is made up of high temperature insulation layer and bottom heating device.
described cooling room inside is provided with condenser, gas exhaust duct, is connected with outside temperature control unit.
