Centrifugal casting device and method for alloy steel casting and forging

Abstract

The invention discloses a centrifugal casting device and method for alloy steel casting and forging. The centrifugal casting device comprises a bottom plate, a second centrifugal casting cylinder is arranged in a fixing ring on the left side, a first centrifugal casting cylinder corresponding to the second centrifugal casting cylinder is arranged in a fixing ring on the right side, an output shaftof a second motor is provided with a crankshaft connected with a mounting frame, a sleeve is arranged on the outer side of the crankshaft, an injection hopper is arranged at the top of the mounting frame, a second casting pipe penetrating through the second centrifugal casting cylinder is arranged on the outer side of a first casting pipe, a casting port is arranged on the outer side of a secondcasting pipe, and a connecting rod is arranged between the second casting pipe and the sleeve. The second motor and the crankshaft are arranged, the crankshaft is driven to rotate by starting the second motor, the sleeve on the outer side drives the second casting pipe which is connected with the sleeve through the connecting rod to move leftwards and rightwards, the effect that the casting position is not fixed is achieved, casting is uniform, and casting quality is high.

Description

technical field [0001] The invention belongs to the technical field of centrifugal casting machines, and in particular relates to centrifugal casting equipment and a casting method for alloy steel casting and forging. Background technique [0002] A casting method in which liquid metal is poured into a rotating mold, filled and solidified into a casting under the action of centrifugal force. The machine used for centrifugal casting is called centrifugal casting machine. According to the direction of the rotation axis of the mold, the centrifugal casting machine is divided into three types: horizontal, vertical and inclined. The horizontal centrifugal casting machine is mainly used for casting various tubular castings, such as gray cast iron ductile iron water pipes and gas pipes, with a minimum diameter of 75mm and a maximum diameter of 3000mm. In addition, it can also cast large-diameter copper rollers for paper machines, various Carbon steel, alloy steel pipe, and double...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of centrifugal casting equipment and its casting method for alloy steel casting and forging, to solve the above-mentioned background technology. The diversion groove guides the molten steel into the mold cylinder. Since the position of the diversion groove is fixed, the molten steel poured into the mold cylinder can only flow from one end of the mold cylinder to the other end, and the temperature of the molten steel will increase when it flows. gradually decreases, which leads to a large temperature difference between the two ends of the casting, which causes the problem of uneven hardness at both ends of the casting after production.
