Embodiment Construction

[0011] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as Figure 1~3 As shown, a flow-following inoculation device is provided with a column 6 above the pouring port of the ladle 1, the column 6 is fixed on the ladle cover 2, and a barrel body 8 is movably installed on the column 6, and the barrel body 8 can wrap around the column 6 spins. The top of the barrel body 8 is provided with an inlet, and the bottom is provided with an outlet. Above the inlet, a loam cake 4 that can rotate around the column 6 is provided. The cover 4 makes its round hole coincide with the entrance of the barrel body 8, the inoculant is added into the barrel body 8, and the upper cover 4 is rotated in the opposite direction to block the entrance of the barrel body 8.

[0013] The below of barrel body 8 is provided with flow adjustment plate 11 and base 12, and flow adjustment plate 11 and base 12 are respectively prov...

Abstract

The invention discloses a stream inoculation device. A stand column (6) is arranged above the sprue gate of a pouring ladle; the stand column is movably provided with a bucket body (8); the top of the bucket body (8) is provided with an inlet; the bottom of the bucket body (8) is provided with an outlet; an upper cover (4) is arranged above the inlet; a base (12) is arranged below the bucket body (8); the base (12) is provided with a round hole corresponding to the outlet of the bucket body; a rotary connecting plate (10) is fixed on the outer side wall of the bucket body (8) and is hinged with a push-pull rod (15); one end of the push-pull rod (15) is connected with a return spring (14); the other end of the push-pull rod (15) is hinged with an oscillating rod (9); and a handheld rod (13) is fixed on the other end of the oscillating rod (9). The stream inoculation device has the characteristics of simple structure, low cost, easiness for popularization and implementation and flexibility in application, can be suitable for various casting production modes and can be used for overcoming the boundedness that a stream inoculation machine only can be used on an automatic production line. According to the stream inoculation device, the size, amount, form and distribution of graphite can be effectively improved so as to improve the homogeneity of the internal organization, the comprehensive mechanical performance and the machining performance of the casting, and the stream inoculation device has the effects of improving the product grade and comprehensively lowering the cost.

Description

Technical field: [0001] The invention relates to a device for adding an inoculant in the casting process of molten iron in the foundry industry. Background technique: [0002] In the casting production process, in order to ensure that the casting material has good mechanical properties, it is necessary to add an inoculant during the molten iron pouring process. There are many forms of addition, and the most effective form is inoculation with flow. At present, domestic and foreign foundries use flow incubators produced abroad. The cost of this equipment is more than one million yuan. Because the investment cost is too high, it is difficult to be widely used. Invention content: [0003] The present invention aims at the above-mentioned deficiencies of the prior art, and provides a streamline incubating device with simple structure, convenient operation and low cost. [0004] The technical solution of the present invention is: a flow-following inoculation device, which is pr...
