Abstract
The utility model provides a powder metallurgy electric furnace cooling system and belongs to the technical field of power metallurgy. The powder metallurgy electric furnace cooling system solves the problem that the existing electric furnace cooling system is slow in speed and bad in effect. The powder metallurgy electric furnace cooling system comprises a shell of an electric furnace and an inner container of the electric furnace, wherein a cooling jacket is formed between the shell and the inner container, a first water inlet and a first water outlet are installed on two side walls of the shell, the first water inlet and the first water outlet are connected with the cooling jacket, and the top of a inner cavity of the inner container is provided with a water cooling device. The powder metallurgy electric furnace cooling system has the advantages of being fast in cooling speed.
Description
Technical field
The utility model belongs to powder metallurgical technology, relates to a kind of cooling system, particularly a kind of powder metallurgy electric furnace cooling system.
Background technology
Product temperature after powder metallurgy sintered is generally more than 1000 ℃, need behind the sintering product temperature is lowered, for product is cooled down at short notice, the mode that generally adopts at present is at the electric furnace end place of coming out of the stove a few electricity-saving oven cooling jackets to be installed, movement by guipure or graphite cake, product is dropped to below 60 ℃ by high temperature, finishes sintering process.Although this mode can play good cooling effect, but still exist some problems: mainly be that cooling velocity is slow, the speed that cools down is 30 °/minutes, do not having in the sufficiently long cooling jacket situation, the easy oxidation of product, and product tissue odds is even, can not obtain tiny disperse shape crystal grain pearlitic structrure.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the fast and adjustable powder metallurgy electric furnace of a kind of cooling velocity cooling system.
The purpose of this utility model can realize by following technical proposal: a kind of powder metallurgy electric furnace cooling system, the shell and the inner bag that comprise electric furnace, be formed with cooling jacket between shell and the inner bag, the shell two side is provided with water inlet pipe one and outlet pipe one, described water inlet pipe one and outlet pipe one are communicated with above-mentioned cooling jacket, and it is characterized in that: the inner cavity top of described inner bag is provided with water-cooling apparatus.
In above-mentioned a kind of powder metallurgy electric furnace cooling system, described water-cooling apparatus comprises the continuous coil pipe of a cover U-shaped and is arranged on water inlet pipe two, outlet pipe two on the inner bag two side, and described continuous coil pipe is between water inlet pipe two and outlet pipe two and be communicated with water inlet pipe two and outlet pipe two.
In above-mentioned a kind of powder metallurgy electric furnace cooling system, be fixed with a plurality of fin on the described continuous coil pipe.
Compared with prior art, this powder metallurgy electric furnace cooling system carries out cooling work inside and outside having adopted two cover water cooling systems realizations simultaneously, thereby can so that the product in the inner bag can cool off fast, improve the quality of products.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, shell; 2, inner bag; 3, cooling jacket; 4, water inlet pipe one; 5, outlet pipe one; 6, continuous coil pipe; 7, water inlet pipe two; 8, outlet pipe two; 9, fin.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this powder metallurgy electric furnace cooling system comprises shell 1 and the inner bag 2 of electric furnace, be formed with cooling jacket 3 between shell 1 and the inner bag 2, shell 1 two side is provided with water inlet pipe 1 and outlet pipe 1, water inlet pipe 1 and outlet pipe 1 are communicated with above-mentioned cooling jacket 3, and the inner cavity top of inner bag 2 is provided with water-cooling apparatus.
Further, water-cooling apparatus comprises the continuous coil pipe 6 and the water inlet pipe 27, the outlet pipe 28 that are arranged on inner bag 2 two sides of a cover U-shaped, continuous coil pipe 6 is between water inlet pipe 27 and outlet pipe 28 and be communicated with water inlet pipe 27 and outlet pipe 28, is fixed with a plurality of fin 9 on the coil pipe 6 continuously.
Extraneous cooling water enters into cooling jacket 3 by water inlet pipe 1, and then the cooling water that is arranged in cooling jacket 3 cools off the product of inner bag 2 and inner bag 2 takes heat out of from outlet pipe one 5 discharges; Extraneous cooling water directly cools off the product of inner bag 2 by the continuous coil pipe 6 that water inlet pipe 27 enters into U-shaped, and cooling effect is very good and speed is fast.The utility model technology is by under the prerequisite of original cooling jacket, design in addition the independent continuous coil pipe 6 of cooling U-shaped that can control chilling temperature of a cover, and be directly installed on water jacket inner bag 2 the insides, can improve fast and effectively cooling velocity, because from sintering part out, amount of heat is directly absorbed by the water in the continuous coil pipe 6 of U-shaped out, taken away a large amount of heats, make the cooldown rate of product can reach 60 ℃/minutes, product managerization detection out, pearlite reaches more than 80%, and is specially adapted to sinter-hardened steel.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
