Abstract

The invention discloses a continuous casting type electroslag furnace with a self-arc-striking mechanism, and relates to the technical field of electroslag furnaces. According to the continuous casting type electroslag furnace, during use, firstly, a furnace body upper shell is lifted up through a lifting device, then, a furnace charge grid is filled with metal raw materials, then, the furnace body upper shell is buckled on a furnace body outer shell, then fuel gas is injected into an electroslag furnace body through a fuel gas injection pipe, electric arcs are introduced through two electrode needles, under combustion supporting of the fuel gas, when the electric arcs are formed, energy is concentrated, the temperature of an arc area is 3000 DEG C or above, and therefore the metal raw materials are smelted; and if the two electrode needles cannot generate the electric arcs due to the short arc length of the electric arcs, an adjusting cylinder drives the two electrode needles to move downwards through a mica ceramic insulating plate, two limiting blocks are symmetrically arranged, and the adjacent sides of the two limiting blocks are inclined planes, when the two electrode needles move downwards, the lower ends of the two electrode needles are gradually close to each other, and therefore the electric arcs are generated.

Description

technical field [0001] The invention relates to the technical field of electroslag furnaces, in particular to a continuous casting electroslag furnace with a self-arcing mechanism. Background technique [0002] An electric arc furnace refers to an industrial furnace that uses the heat generated by an electric arc to smelt ores and metals. When the gas discharge arc furnace forms an electric arc, the energy is very concentrated, and the temperature in the arc area is above 3000 °C. For smelting metals, the electric arc furnace is more flexible than other steelmaking furnaces. It can effectively remove impurities such as sulfur and phosphorus, the furnace temperature is easy to control, and the equipment occupies a small area. It is suitable for smelting high-quality alloy steel. Electric arc furnaces can be divided into three-phase electric arc furnaces, consumable electric arc furnaces, single-phase electric arc furnaces, and resistance electric arc furnaces according to th...
