Description
Technical field
The utility model relates to a kind of even slow cooling device of the large-scale steel-casting for carrying out shake out at 500 ~ 600 DEG C of temperature, especially relates to a kind of annealing device for steel-casting hot shake-out.
Background technology
Traditional Steel Castings process step is: moulding, cast, cooling, shake out, knockout, preheating, rising head cutting, heat treatment, gouge, relief grinding, ball blast, processing, welding etc.Wherein, for preventing steel-casting because cooling rate is uneven, the temperature difference comparatively large and crack, the defect such as distortion, large-scale steel-casting even could must to be unpacked under lower temperature shake out by Slow cooling < 300 DEG C after being cast in sandbox.
Mostly adopt silica sand due to during large-scale steel-casting moulding, press against ore in sand form etc. as raw and auxiliary material, adopt box moulding and cored-up mould mode, steel-casting after being cast initial stage cooling is very fast, is generally down to 500 ~ 550 DEG C through 5-7 days temperature, temperature reduction of speed slows down subsequently, is generally 20 ~ 40 DEG C/day.Low alloy steel castings meets shake out to be taken seeking time and is generally 16 ~ 20 days, high-alloy steel due to alloy-steel casting constituent content high, cracking risk is larger, shakeout temperature requires lower, mostly shake out below 100 DEG C, its pressure case, shake out time are longer, generally more than 30 days.Pressure case, shake out time are long, and cause the turnover rate of the resources such as melt pit, sandbox mainboard, case band to reduce, place holding time is long, has a strong impact on the production efficiency of foundry.
Due to the demand of production cycle, start have manufacturer to select to carry out hot shake-out to foundry goods, then select heat-treatment furnace as slow cooling frock.Although this method improves the utilization rate in the wage source, make-up department such as melt pit, sandbox mainboard, but occupy heat-treatment furnace again simultaneously, and foundry goods carries sand, arbor, running channel etc. and brings a large amount of work loads to the cleaning of heat-treatment furnace, add the production cost of heat treatment step.
Also have in prior art and build special slow cooling melt pit, for slow cooling after large-scale steel-casting hot shake-out.This special slow cooling melt pit not only possesses heat supply and temperature measuring equipment, is also equipped with inlet and outlet to adjust foundry goods cooling velocity, effectively can controls the cooling velocity after steel-casting shake out, reduce foundry goods tearing tendency.But it is huge to build special slow cooling melt pit up-front investment, adds the production cost of shake out operation, and this special slow cooling melt pit does not possess the function of high temperature knockout.
Also do not overcome the device of above-mentioned defect at present.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, there is provided a kind of structure uniqueness, for controlling the cooling velocity after large-scale steel-casting hot shake-out, reduce the temperature difference of foundry goods different parts, avoid foundry goods to occur the defect such as crackle, distortion, make the integration of shake out, knockout simultaneously, shorten shake out, the production cycle of shakeout operation, simple to operate, safe and reliable a kind of annealing device for steel-casting hot shake-out.
