A safe casting method based on ingot casting machine

Abstract

The invention discloses a safe casting method based on a pig casting machine. The safe casting method based on the pig casting machine comprises the following steps of (1) enabling casting liquid in asmelting furnace of the pig casting machine to enter a distribution plate through a guide slot; (2) enabling a flame spray head of a preheating device to enter a casting slot, preheating the inner wall of the casting slot, enabling the casting slot to move forward at constant speed during the preheating process, and after finishing preheating, enabling the flame spray head to retreat from the casting slot; (3) enabling the casting slot to arrive at a first detection unit, and using the first detection unit for acquiring temperature and humidity data in the casting slot; (4) enabling the casting slot to arrive at a second detection unit, using the second detection unit for acquiring temperature and humidity data in the casting slot again, and judging whether the distribution plate needs tobe casted or not through a programmable logic controller (PLC); and (5) when the casting condition is not met, enabling the casting slot not to cast when passing through the distribution plate; and when the casting condition is met, enabling the casting slot to cast when passing through the distribution plate. According to the safe casting method based on the pig casting machine provided by the invention, the casting slot is automatically preheated, so that the time and the effort are saved, and the heating efficiency is high; and the temperature and the humidity of the casting slot are detected, so that the casting safety is improved.

Description

technical field [0001] The invention relates to the technical field of casting machinery, in particular to a safe casting method based on an ingot casting machine. Background technique [0002] The ingot casting process is an extremely important part of metal smelting. During the ingot casting process, high-temperature molten metal is prone to explosion accidents when it encounters water. The process of explosion caused by high temperature molten metal meeting water is as follows: high temperature molten metal is easy to sink and disperse in water, and quickly granules, prompting a large amount of water to boil and generate high temperature steam; water decomposes to produce hydrogen and oxygen and explodes; Produces hydrogen and spontaneously ignites and explodes. The four factors work together to cause a strong explosion of high-temperature molten metal in contact with water, resulting in casualties and equipment damage. [0003] The water content in the casting mold of ...

Problems solved by technology

[0009] Aiming at the deficiencies of the above-mentioned prior art, the object of the present invention is to propose a safe casting method based on an ingot casting machine, which solves the problem of explosion caused by humid air cooling condensation in the casting tank and accumulation of water when high-temperature molten metal is easily encountered during the ingot casting process. And artificial heating is difficult to control the preheating temperature of the casting tank, resulting in waste of gas source and low heating efficiency.
