Description

Improved casting AZS hook brick sand mould

Technical Field

The utility model belongs to the technical field of refractory material production, concretely relates to improved generation founding AZS couple brick sand mould.

Background

Founding AZS couple brick sand mould at breastwork position is as shown in figure 1 in the glass melting furnace, casting riser 2 including sand mould body 1 and sand mould body 1 top, casting riser 2 well upper portion is square (or cuboid) tube-shape, the lower part is the pyramid form of going up thick thin down, this kind of casting riser adopts two kinds of shapes, the preparation process is loaded down with trivial details, inefficiency, sand mould body right side lower part is equipped with the cavity 3 that is used for the couple of casting couple brick, couple brick casting back of getting out of the case, because brick type structural reason, produce stress easily and cause the crackle to appear in the right angle contained angle (the corner 7 of the upper left corner of cavity 3 promptly) department of couple and brick body, the quality is difficult to control, thereby cause the brick to scrap.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point among the prior art, provide a simple structure, casting rising head make things convenient for, improve improved generation founding AZS couple brick sand mould of couple department casting quality.

In order to solve the technical problem, the utility model adopts the following technical scheme: improved generation founding AZS couple brick sand mo (u) ld, including the sand mo (u) ld body with establish the casting rising head at sand mo (u) ld body top, sand mo (u) ld body right flank top-down is last perpendicular, well ramp face and lower perpendicular face in proper order, and well ramp face top side and last perpendicular face downside butt joint, well ramp face downside and the lower perpendicular face upside butt joint, the slope setting of well ramp face high left and low right side.

The included angle between the middle slope surface and the upper vertical surface is 15-20 degrees.

The whole casting riser is of a conical cylinder structure with a thick upper part and a thin lower part, the lower end of the casting riser is bonded to the top of the sand mould body, and the inner diameter of the lower port of the casting riser is equal to the inner diameter of the upper port of the sand mould body in size.

The thickness of the casting riser is 30 mm.

Adopt above-mentioned technical scheme, in order to solve this brick couple department right angle crack problem, the utility model discloses the sand mould improves, and the whole sand mould of self-hardening type is made into to the sand mould body, and the sand mould does not need to dry, and 24 hours back sand mould intensity just can reach the operation requirement after the room temperature is placed, makes into the shape of a well slope with sand mould body right side corner simultaneously, changes the cooling direction of thermal stress in the cooling process to reduce the probability that the crackle produced. Meanwhile, the thickness of the hook brick at the position is increased due to the arrangement of the slope surface, so that the heat insulation effect of the glass melting furnace is correspondingly improved.

The casting riser is made into a self-hardening integral shape of a conical cylinder with the wall thickness of 30mm and thick upper part and thin lower part, the casting riser does not need to be dried, the strength of a sand mold can meet the use requirement after the casting riser is placed for 24 hours at room temperature, then the top surface of a sand mold body and the lower port of the casting riser are bonded together, then the sand mold is buried in heat-insulating sand, the periphery is filled with silicon sand, AZS molten liquid with the melting temperature of 1800 plus 2000 ℃ in a three-phase electric arc furnace is poured into a cavity, then the casting riser is treated, the heat-insulating sand is covered with heat-insulating sand, the thickness of the covering sand is not less than 200mm, heat insulation is carried out, after heat insulation and annealing are carried out for 7-9 days, the sand mold on the surface of the brick is removed, and then mechanical processing is carried out.

To sum up, the utility model discloses simple structure easily makes, makes things convenient for the drawing of patterns, has solved the crackle problem of the corner of couple brick, has improved the product quality of couple brick, has also improved thermal-insulated heat preservation effect simultaneously.

Detailed Description

As shown in figure 2, the utility model discloses an improved generation founding AZS couple brick sand mo (u) ld, including sand mould body 1 with establish the casting rising head 2 at sand mould body 1 top, sand mould body 1 right flank top-down is last perpendicular 4, well ramp 5 and lower vertical plane 6 in proper order, and well ramp 5 top side docks with 4 lower sides of last perpendicular, and 5 lower sides of well ramp dock with 6 upper sides of lower vertical plane, and the slope setting of 5 high-left-right sides of well ramp sets up.

The angle between the middle slope surface 5 and the upper vertical surface 4 is 15-20 degrees, preferably 17 degrees.

The whole casting riser 2 is of a conical cylinder structure with a thick upper part and a thin lower part, the lower end of the casting riser 2 is adhered to the top of the sand mould body 1, and the inner diameter of the lower end opening of the casting riser 2 is equal to the inner diameter of the upper end opening of the sand mould body 1 in size.

The thickness of the casting riser 2 is 30mm, so that the casting riser not only has better strength, but also has better heat preservation.
