Ferroalloy furnace's accident analysis

CThe main reason is that some smelters have weak safety awareness and numbness of thought, do not abide by the safe operation procedures for tapping and oxygen blowing, or are affected by habitual illegal operators, and operate against regulations when the safety protection devices are lack and damaged and the safety protection measures are not implemented in place, resulting in accidents.

Ferroalloy furnace's introduction

Main equipment for smelting ferroalloy. Ferroalloy electric furnaces are divided into reduction electric furnaces and refining electric furnaces. There are various types of electric furnace, such as electric furnace with open or semi arc operation, or electric furnace with submerged arc operation. Electric refining furnace is used to refine medium carbon, low carbon and micro carbon ferroalloys.

Low micro carbon ferrochrome furnace's basic introduction

As a kind of ferrochrome with low carbon content, low-carbon ferrochrome is an important additive in steelmaking and casting. At ordinary times, our common stainless steel and high alloy ferritic steel are smelted by adding low-carbon ferrochrome in smelting. It can be said that low-carbon alloys are widely used.

Ferroalloy submerged arc furnace: a solution to the temperature rise and redness at the bottom of the furnace

Traditional ferroalloy submerged arc furnaces generally use pre-baked carbon blocks and wide coarse joints to build the furnace lining, and adjust the primary current to control the depth of the electrode inserted into the furnace (that is, the load of the electric furnace). Take the main equipment of a company's 2*25.5MVA submerged arc furnace as an example. Its lining adopts semi-graphite charcoal brick fine-seam masonry technology, but the redness of the furnace bottom appeared three months after the furnace was opened. Through fine furnace anatomy and cause analysis, find out the solution to the problem.

Ferroalloy submerged arc furnace have three important characteristics

Energy saving: The production of ferroalloys accounts for a large proportion of electricity consumption, so reducing power consumption and increasing the cost of thermal efficiency is an effective way to reduce the production cost of ferroalloys.
