Embodiment 1

[0029] Such as figure 1 , figure 2 As shown, a stacked box casting method for hammerheads of crushers is carried out in sequence as follows:

[0030] A. Along the parting line of the hammer handle, the upper and lower molds are combined to form a hammer mold. There is a hollow part in the middle of the hammer mold. The hollow part is the shape of the hammer handle and the composite part. Manganese steel molten steel up to 1500°C is poured into the hammer mold from the gate, and the manganese steel contains C 0.75%, Si 0.2%, Mn 10.5%, Cr 0.5%, Mo 0.1%, Ni0.01%, Cu 0.01%, P 0.008%, S 0.008%, when cooled to 250°C, open the box, knock off the gate first, and then polish it to get a high manganese steel hammer handle;

[0031] B. Remove the impurities on the surface of the composite part of the high manganese steel hammer handle 4, put on the hammer head lost foam 5, then brush the hammer head lost foam 5 with a refractory coating, and bake the assembled hammer head model 3 in a...

Embodiment 2

[0041] A stacked box casting method for hammer heads of crushers, which is carried out in sequence as follows:

[0042] A. Along the parting line of the hammer handle, the upper and lower molds are combined to form a hammer mold. There is a hollow part in the middle of the hammer mold. The hollow part is the shape of the hammer handle and the composite part. Manganese steel molten steel up to 1525°C is poured into the hammer mold from the gate. The manganese steel contains C 1.025%, Si 0.5%, Mn 11.75%, Cr 1.25%, Mo0.1%, Ni 0.105%, Cu 0.055%, P 0.0085%, S 0.0085%, when cooled to 300°C, open the box, knock out the gate first, and then polish it smooth to get a high manganese steel hammer handle;

[0043] B. Remove the debris on the surface of the compound part of the high manganese steel hammer, put on the lost foam of the hammer head, and then brush the refractory coating on the lost foam of the hammer head, and bake the assembled hammer head model in a baking room at 55°C for ...

Embodiment 3

[0053] A stacked box casting method for hammer heads of crushers, which is carried out in sequence as follows:

[0054] A. Along the parting line of the hammer handle, the upper and lower molds are combined to form a hammer mold. There is a hollow part in the middle of the hammer mold. The hollow part is the shape of the hammer handle and the composite part. Manganese steel molten steel up to 1550°C is poured into the hammer mold from the gate. The manganese steel contains C 1.30%, Si 0.8%, Mn 13%, Cr 2%, Mo 0.1%, Ni0.2%, Cu 0.1%, P 0.009%, S 0.009%, when cooled to 350°C, open the box, knock out the gate first, and then polish it smooth to get a high manganese steel hammer handle;

[0055] B. Remove the sundries on the surface of the compound part of the high manganese steel hammer, put on the lost foam of the hammer head, and then brush the refractory coating on the lost foam of the hammer head, and bake the assembled hammer head model in a baking room at 60°C for 1 hour Or ...

Abstract

The invention relates to the technical field of hammerhead casting of a crusher, in particular to a method for casting stacked boxes of hammerheads of a crusher. A stacked box casting method for the hammer head of a crusher, which is carried out in sequence as follows: A, making a high manganese steel hammer handle; B, assembling the hammer head model C, combining several bottom sand core boxes (1) and top sand core boxes (2) Place and fix the stacked boxes from bottom to top; D, molten iron casting, high manganese steel hammer handle (4) and high chromium cast iron joined together; E, unpacking, polished smooth; F, quenching, to get the hammer head of the crusher finished product. The invention has the advantages of simple process, power saving, labor saving, low production cost, simple molding method, high casting molding quality and high productivity.

Description

technical field [0001] The invention relates to the technical field of hammerhead casting of a crusher, in particular to a method for casting stacked boxes of hammerheads of a crusher. Background technique [0002] Crusher is a crushing machine widely used in industries such as cement, ceramics, mining and electric power. The hammer head is its main wearable part. Great progress has been made, but the hammer head is still one of the parts with the shortest life and the largest consumption, and bimetallic composite is an effective way to solve this problem; the hammer head can be divided into hammer handle and hammer head according to the nature of work Two parts, different parts require different performance, the hammer handle requires comprehensive mechanical properties, and must have certain strength and toughness; while the main part of the hammer head wear is the hammer head, so the hammer head is required to have high wear resistance Performance, in order to extend the...
