Problems solved by technology
[0002] In the prior art, wear-resistant steel balls are formed by sand molds. On the production line, the transmission mechanism drives the sand molds one by one to pass under the holding furnace. The molten steel is stored in the holding furnace. By controlling the valve below the holding furnace, the molten steel passes through the sand mold. The gate and runner of the mold then enter the cavity. After the molten steel enters the cavity of the sand mold, it gradually cools down. When the molten steel in the sand mold reaches a certain height, the valve needs to be manually adjusted to allow the molten steel to slowly flow in for refilling. This process needs to be judged by the experience of technicians. Therefore, the feeding operation cannot be accurately controlled, resulting in waste of materials or the quality of the steel balls obtained is not up to standard.

The invention discloses a temperature control type automatic steel ball forming die feeding system used for continuous casting of wear-resistant steel balls. Dies are placed on a transmission mechanism, a heat preserving furnace is located above the dies, a discharge port is arranged below the heat preserving furnace, a sprue is arranged at the top of each die and communicated with an internal cavity of the die through a runner, a real-time flow control valve is arranged at the discharge port of the heat preserving furnace and used for controlling flow rate of molten steel, a first temperature detection device is arranged in each die runner, a second temperature detection device is arranged at the sprue of each die, and position sensors, the first temperature detection devices and the second temperature detection devices are all in communication connection with a control device. The invention further discloses a control method adopting the automatic feeding device for wear-resistant steel ball casting. Feeding control in the process of continuous casting of the wear-resistant steel balls is realized, and the system is simple in structure and accurate in control.
