Abstract

A cooling temp controller for the electric arc furnace with non-consumable electrode to control the cooling speed of alloy and eliminate the defects is composed of air-tight stainless steel jacket, stainless steel casing with circular top opening, electric resistance wire furnace, and the refractory insulating material between said electric resistance wire furnace and stainless steel casing. The heater, temp controller and temp measurer are linked with said electric resistance wire furnace via the terminals on said stainless steel jacket.

Description

technical field [0001] The invention relates to a cooling temperature control device, in particular to a cooling temperature control device for a non-consumable electrode electric arc furnace, which is used in the field of smelting equipment. Background technique [0002] At present, the non-consumable electrode electric arc furnace is a small electric arc furnace commonly used for melting alloys. Its cooling device is a water-cooled copper crucible. Due to the forced water cooling, the cooling rate of each part of the alloy ingot smelted in the water-cooled copper crucible varies greatly, resulting in great differences in microstructure and mechanical properties. Moreover, due to rapid cooling, there are a large number of casting defects (pores, cracks, etc.) in the obtained alloy ingot, which seriously affects the practical application and even performance evaluation of the material. But the water cooling device cannot be removed, because without the water cooling device...
