Abstract
The utility model relates to a box type quenching device used for heat treatment of an extra thick plate, which is provided with a box type quenching water tank. A high-pressure gas or water nozzle is arranged in the quenching water tank so that water circulation temperature is uniform, a steam film on the surface of a steel plate is reduced, and water can absorb the heat of the steel plate to the largest extent. A quenching steel plate clamp is provided for lifting the extra thick plate. By adopting the technical scheme, the box type quenching device of the extra thick plate plays an important role in shortening high-temperature staying time of cooling process of the extra thick plate and finishing heat treatment a quenching procedure. The box type quenching device of the extra thick plate can carry out quenching and tempering process of extra thick plates with special specifications including Cr-Mo series steel, steel for nuclear power, steel for high-pressure steam drums, low content alloy with high strength and alloy steel, further has vital significance to the improvement of performance of the extra thick plate and product grade, and has wide application prospect.
Description
Technical field
The utility model relates to the HTFX of special heavy plate, is specifically related to a kind of heat treated box quenching device of special heavy plate that is used for.
Background technology
Special thick steel (example: Cr-Mo Series Steel, nuclear power are with modified with steel, high-strength low-alloy, steel alloy of steel, high pressure drum) is mainly used in a plurality of fields such as bridge, boiler, pressurized vessel, boats and ships.Big thickness special heavy plate is because substance is big, special requirement (speciality, special thick etc.); Can not heat-treat at roller hearth heat-treated furnace, exterior mechanical stove; Can only heat-treat at car type furnace, do not have corresponding quench systems and handle special car type furnace thick, extra heavy, speciality, and general cooling system can't reach the cooling rate requirement of these steel; So need a cover special heavy plate quench systems, can satisfy the heat-treatment quenching device that special heavy plate is cold soon, quench simultaneously.
Summary of the invention
To above-mentioned situation, for the special heavy plate Cr-Mo Series Steel that solves special requirement, nuclear power with steel, high pressure drum modified problem with steel, high-strength low-alloy, steel alloy, the purpose of the utility model provides the box quenching device of a kind of special heavy plate.
For achieving the above object; The technical scheme that the utility model is taked is that this quenching device has box quenching tank; Set inside at the quenching tank has high pressure gas, water spouting nozzle, is beneficial to water loop temperature and evenly reaches the vapor film that reduces surface of steel plate, makes water to absorb the steel plate heat to greatest extent; Through shortening the special heavy plate high temperature profit reduction and reserving time, by the quick cooling metal sheets of speed of cooling of processing requirement; And the handling special heavy plate is provided with the hardened steel plate holder.
Because the utility model has been taked technique scheme, provides a kind of special heavy plate the box type of cooling for producing big thickness special heavy plate,, accomplish the heat-treatment quenching operation to special heavy plate process for cooling shortening fast steel plate high-temperature residence time; The special requirement special heavy plate Cr-Mo Series Steel that this heat treatment tank type quenching device is carried out, nuclear power are with steel, the high pressure drum hardening and tempering process with steel, high-strength low-alloy, steel alloy; For the performance that improves special heavy plate; Improve product specification and have great importance, have broad application prospects.
Description of drawings
Below in conjunction with accompanying drawing, the constitutional features of the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, 1. hardened steel plate holder, 2. special heavy plate (special requirement), 3. box quenching tank, 4. high pressure gas, water spouting nozzle.
Embodiment
Referring to accompanying drawing, the said quenching device of the utility model has box quenching tank 3, in the set inside of quenching tank 3 high pressure gas, water spouting nozzle 4 is arranged; Be provided with hardened steel plate holder 1 on the top of quenching tank; Before by the entry of quench steel plate, box quenching tank 3 has been full of water, and special requirement special heavy plate 2 heats by the quenching technology temperature in car bottom furnace, and special heavy plate is by technological temperature requirement heating, and the plate temperature can be come out of the stove after passing through and burning evenly; Chassis is left burner hearth, and the steel plate that the automobile-used quenched nickelclad folder 1 in sky will be in quenching temperature is sling, and level is put into jumbo box quenching tank 3; And fall the about 1.8m of depth of water place, and the feed water valve group is opened, and steel plate is fallen prescribed position; Hardened steel plate holder 1 still tangles steel plate; By the recirculated water of about 600/700 m3 in quench steel plate above and below, its light plate entry front opening high pressure water, high pressure gas utilize high pressure gas, water spouting nozzle 4 that the speed of water with 4m/s is formed the laminar flow cooling and forms overflow from the steel plate above and below; Be beneficial to water loop temperature and evenly reach the vapor film that reduces surface of steel plate; Make water to absorb the steel plate heat to greatest extent, through shortening the special heavy plate high temperature profit reduction and reserving time, by the quick cooling metal sheets of speed of cooling of processing requirement.Steel plate in water tank with certain time; The upper surface of steel plate will insert the temperature downtrending that contact thermocouple shows and write down quilt quenching or fast cold steel plate continuously; When the final cooling temperature of temperature drop to processing requirement, withdraw from contact thermocouple, hang the steel plate water outlet with hardened steel plate holder 1 subsequently; Be placed on the steel stand that dries in the air, wait to get into the tempering process of car bottom furnace.
Enforcement recited above is the technical scheme of unrestricted the utility model in order to explanation only; Under the prerequisite of the design philosophy that does not break away from the utility model; Any modification or local replacement that those skilled in the art make the present technique scheme all should be encompassed in the middle of the claim scope of the utility model.
