Casting machine

Abstract

The invention provides a casting machine which comprises a hearth, a furnace lining, a coil, a feeding channel and a discharging channel. The appearance of the furnace lining is in a round shape, and a channel boss is arranged on the inner wall of the furnace lining; the coil is arranged on the outer side of the furnace lining; and the feeding channel and the discharging channel penetrate the channel boss of the furnace lining to be communicated with the hearth. The casting machine has the beneficial effects that the internal space of the hearth is expanded, the limited internal space of the coil is reasonably and effectively utilized, the duty ratio of molten iron in the coil is remarkably improved, and the energy efficiency is obviously improved. A diamond-type coil is replaced by the regular round coil, so that the manufacturing process is simple and practical, the appearance size is controllable, the round coil is simple to assemble, and the whole machine quality is remarkably improved. Furthermore, the overheating time of molten iron is shortened, and the problem of nodularization degeneration is effectively solved.

Description

technical field [0001] The invention relates to a pouring machine, in particular a coreless heating air pressure control pouring machine is designed. Background technique [0002] The pouring machine is a device that presses the molten metal out of the top of the closed pouring container by means of regulated compressed air or inert gas into the top of the pouring container. [0003] figure 1 It is a cross-sectional schematic diagram of the existing pouring machine. [0004] like figure 1 As shown, the hearth 1 of the existing pouring machine is circular, and in order to meet the requirements of the iron channels 5 and 6 occupying space, the shape of the furnace lining 2 is rhombus. Therefore, the coil 3 also adopts a rhombic design and is arranged outside the furnace lining. Similarly, the yoke 4 is also rhombus-shaped and is located outside the coil. This structure mainly has the following disadvantages: [0005] 1. The duty ratio of molten iron in the coil is too low...

AI Technical Summary

Problems solved by technology

[0005] 1. The duty ratio of molten iron in the coil is too low, resulting in low energy efficiency

[0006] 2. The manufacturing process of the diamond-shaped coil is complicated, and the shape is difficult to guarantee, resulting in difficulty in assembly and affecting product quality

[0007] 3. Due to the efficiency problem, there is a phenomenon of spheroidization decline
