Abstract

This invention discloses a slab electroslag furnace, which comprises: an AC power supply, an electrode elevator, an electrode, a crystallizer, a support platform, an ingot feeder, a liquid level detector of molten steel, a rotary frame, a weight sensor, an ingot discharger, and a control system. The crystallizer is fixed in the support platform. The rotary frame is fixed on the support platform, and can move along a fixed track. The electrode elevator is set on the platform of the rotary frame, and can be horizontally adjusted. The weight sensor is set at the contact surface of the electrode elevator and the platform of the rotary frame. One end of the electrode (monopolar or bipolar) is fixed with the electrode elevator, and the other one is set in the crystallizer. The liquid level detector of molten steel is set on the sidewall of the crystallizer. The ingot discharger is set on a frame below the support platform. A wagon is fixed on the ingot discharger. The ingot feeder is fixed in the wagon. The control system, elevator, weight sensor, ingot discharger and wagon are electrically connected.

Description

technical field [0001] The invention belongs to the technical field of metal electroslag remelting equipment, and particularly relates to a slab electroslag furnace, which is applied in the process of metal remelting and smelting. Background technique [0002] Electroslag furnace is a kind of metallurgical equipment that uses the resistance heat generated when electric current passes through molten slag as a heat source to smelt metal. After electroslag remelting, the content of gas and inclusions in the steel can be reduced, and a steel ingot with uniform composition, dense structure and excellent quality can be obtained. The ductility and toughness of the alloy, especially the transverse properties, are improved, anisotropy is reduced, and various macroscopic and microscopic defects are eliminated or mitigated. Therefore, electroslag furnace equipment has been widely used in steel, machinery and other industries at home and abroad. [0003] At present, domestic electrosl...
