Abstract
A heat treatment device for alloy castings comprises a heat preservation heating furnace for keeping the temperature of castings with sand molds in the solidification process at a solution treatment temperature, and a temperature-controlled water tank for performing solution treatment on the castings with the sand molds. The foundry goods temperature that is in the solidification process through control is close to the solution treatment temperature, makes the utility model discloses compare with traditional alloy heat treatment device, shortened solution treatment's heating rise time, the saving running cost that is showing.
Description
Technical field
The utility model relates to a kind of thermal treatment unit, especially a kind of thermal treatment unit of alloy-steel casting.
Background technology
Phase change material has the ability that changes its physical condition in certain temperature range.With the solid-liquid phase change is example, when being heated to melt temperature, just produces the phase transformation from solid-state to liquid state, and in the thaw process, the phase change material absorption also stores a large amount of latent heat; When phase change material cools off, to be dispersed in the environment in the certain temperature range of the heat word of storage and go, carry out liquid to solid-state reverse change.In these two kinds of phase transition process, energy stored and that discharge is called latent heat of phase change.
Solution heat treatment is meant that alloy is heated to high temperature single phase region constant temperature to be kept, and makes surplus fully dissolving cooling mutually, to obtain the thermal treatment process of supersaturated solid solution.The purpose of solution treatment is to make various fully dissolvings mutually in the alloy, strengthens sosoloid, and improves toughness and etch resistant properties, eliminates stress with softening, so that continue processing or moulding.Be applicable to the multiple special steel of processing, superalloy, property alloy, non-ferrous metal.The elimination of the cold working hardening between the part that needing after the thermal treatment to be particularly useful for reprocessing, welded workpiece, forming process.
Ageing treatment can be divided into natural aging and two kinds of natural agings of artificial aging are to place open area more than half a year on foundry goods, just shape gently takes place in it, thereby unrelieved stress is eliminated or minimizing, artificial aging is foundry goods to be heated to 550～650 ℃ carry out stress relief annealing, it is saved time than natural aging, it is comparatively thorough that unrelieved stress is removed. for the high temperature suitable artificial aging of use of aluminum alloy casting of work down, and some employing natural aging of the aluminium alloy of working under the room temperature, some must artificial aging; For general aluminium alloy, during natural aging, yield strength is low slightly and solidity to corrosion is better, and when adopting people's timeliness, the alloy yield strength is higher and elongation and solidity to corrosion all reduce.
Core is made up of sand material and suitable binder material, it is stipulating the shape of foundry goods, generally be placed on the inside of mold and casting mold, fill mold and casting mold with metal alloy, behind alloy graining, foundry goods is removed from mold and casting mold, move on to then to handle in the stove and heat-treat, from core, reclaim the sand material, sometimes, also need to carry out ageing treatment.Thermal treatment and ageing treatment are to adjust the process of metal alloy, and the result has alloy to be applicable to the physical property of different occasions.
The utility model content
The purpose of this utility model is to provide a kind of thermal treatment unit of alloy-steel casting.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of thermal treatment unit of alloy-steel casting, it comprise the temperature of the foundry goods that has sand mold that is used for remaining in process of setting the insulation process furnace of solid solution temperature, be used for to the foundry goods that has sand mold carry out solution treatment the temperature control tank, be used for to the described foundry goods that has sand mold carry out solution treatment the temperature control tank, be used to transport the delivery system that the described foundry goods that has sand mold enters described insulation process furnace and temperature control tank.
Because the employing of technique scheme the utlity model has following advantage:
Enter before the temperature control tank carries out solution treatment at foundry goods, be in casting temperature in the process of setting near solid solution temperature by control, make the utility model compare, shortened the heat temperature raising time of solution treatment, saved running cost significantly with traditional alloy thermal treatment unit.
Description of drawings
Fig. 1 is the thermal treatment unit of the related alloy-steel casting of the utility model;
Wherein: 1, foundry goods; 2, insulation process furnace; 3, temperature control tank; 4, delivery system.
Embodiment
The thermal treatment unit of alloy-steel casting as shown in Figure 1, comprise the temperature of the foundry goods that has sand mold 1 that is used for remaining in process of setting the insulation process furnace 2 of solid solution temperature, be used for to the foundry goods 1 that has sand mold carry out solution treatment temperature control tank 3, be used to transport the delivery system 4 that the foundry goods 1 that has sand mold enters insulation process furnace 2 and temperature control tank 3, foundry goods 1 enters process furnace 2 by delivery system 4, is transported to again in the temperature control tank 3 afterwards.
The foundry goods 1 that temperature control tank 3 will have sand mold is quenched into below the aging temp.
Use the thermal treatment process of the thermal treatment unit of above-mentioned alloy-steel casting to comprise the steps: at first, control is in the casting temperature of the foundry goods 1 in the process of setting near solid solution temperature; Then, the foundry goods 1 that will have a sand mold is quenched and is carried out solution treatment in the entry, is quenched into below the aging temp; At last, foundry goods 1 is carried out ageing treatment.
In the present embodiment, control is in the casting temperature of the foundry goods 1 in the process of setting near this step of solid solution temperature, can select to utilize the waste heat supply temperature of the foundry goods 1 that is in the process of setting, foundry goods 1 is placed in the insulation process furnace 2, and the mode that is incubated the regular hour according to solid solution temperature realizes.
